Introduction
Pellet Quality:
Pellet quality is important, please read the following: Your enviro pellet stove has been designed to burn wood pellets only. Do not use any other type of fuel, as this will void any warranties stated in this manual. The performance of your pellet stove is greatly affected by the type and quality of wood pellets being burned. As the heat output of various quality wood pellets differs, so will the performance and heat output of the pellet stove. CAUTION: It is important to select and use only pellets that are dry and free of dirt or any impurities such as high salt content. Dirty fuel will adversely affect the operation and performance of the unit and will void the warranty. The Pellet Fuel Industries (P.F.I.) has established standards for wood pellet manufacturers. We recommend the use of pellets that meet or exceed these standards. Ask your dealer for a recommended pellet type. P.F.I. PELLET STANDARDS: Fines (fine particles)......1% maximum through a 1/8 screen Bulk Density..................40 pound per cubic foot minimum Size.............................. to 5/16 diameter 1 long maximum Ash Content..................1% maximum (Premium grade) ..................3% maximum (Standard grade) Moisture Content...........8% maximum Heat Content.................approximately 8200 Btu per pound minimum ASH: The ash content of the fuel and operation of your stove will directly determine the frequency of cleaning. The use of high ash fuels may result in the stove needing to be cleaned daily. A low ash fuel may allow longer intervals between cleaning. CLINKERING: [clinkers are silica (sand) or other impurities in the fuel that will form a hard mass during the burning process]. This hard mass will block the air flow through the Burn Pot Liner and affect the performance of the stove. Any fuel, even approved types, may tend to clinker. Check the Burn-Pot Liner daily to ensure that the holes are not blocked with clinkers. If they become blocked, remove the liner (when the unit is cold) and clean/scrape the clinkers out. Clean the holes with a small pointed object if required. Refer to the section Routine Cleaning and Maintenance. PELLET FEED RATES: Due to different fuel densities and sizes, pellet feed rates may vary. This may require an adjustment to the slider damper setting or to the auger feed trim setting on low. Since Sherwood Industries Ltd. has no control over the quality of pellets that you use, we assume no liability for your choice in wood pellets. Store pellets at least 36 (1 m) away from the pellet stove.
Introduction
imPoRtant Safety Data:
Please read this entire Owners Manual before installing or operating your ENVIRO Pellet Stove. Failure to follow these instructions may result in property damage, bodily injury or even death. Contact your local building or fire official to obtain a permit and any information on installation restrictions and inspection requirements for your area. To prevent the possibility of a fire, ensure that the appliance is properly installed by adhering to the installation instructions. An ENVIRO dealer will be happy to assist you in obtaining information with regards to your local building codes and installation restrictions. Be sure to maintain the structural integrity of the home when passing a vent through walls, ceilings, or roofs. The stoves exhaust system works with negative combustion chamber pressure and a slightly positive chimney pressure. It is very important to ensure that the exhaust system be sealed and airtight. The ash pan and viewing door must be locked securely for proper and safe operation of the pellet stove. Do not burn with insufficient combustion air. A periodic check is recommended to ensure proper combustion air is admitted to the combustion chamber. Setting the proper combustion air is achieved by adjusting the slider damper located on the left side of the stove. When installing the stove in a mobile home, it must be electrically grounded to the steel chassis of the home and bolted to the floor. Make sure that the structural integrity of the home is maintained and all construction meets local building codes. Minor soot or creosote may accumulate when the stove is operated under incorrect conditions such as an extremely rich burn (black tipped, lazy orange flames). If you have any questions with regard to your stove or the above-mentioned information, please feel free to contact your local dealer for further clarification and comments.
Introduction
ASHES: Disposed ashes should be placed in a metal container with a tight fitting lid. The closed container of ashes should be on a non-combustible floor on the ground, well away from all combustible materials pending final disposal. If the ashes are disposed of by burial in soil or otherwise locally dispensed, they should be retained in the closed container until all cinders have been thoroughly cooled. ELECTRICAL: The use of a surge protected power bar is recommended. The unit must be grounded. The grounded electrical cord should be connected to a standard 115 volts (4.5 Amps), 60 hertz electrical outlet. Be careful that the electrical cord is not trapped under the appliance and that it is clear of any hot surfaces or sharp edges and also must be accessible. If this power cord should become damaged, a replacement power cord must be purchased from the manufacture or a qualified ENVIRO dealer. The EF3s maximum power requirement is 520 watts. GLASS: Do not abuse the glass by striking or slamming the door. Do not attempt to operate the stove with broken glass. The stove uses ceramic glass. Replacement glass must be purchased from an ENVIRO dealer. Do not attempt to open the door and clean the glass while the unit is in operation or if glass is hot. To clean the glass, use a soft cotton cloth and mild window cleaner, gas or wood stove glass cleaner, or take a damp paper towel and dip into the fly ash. This is a very mild abrasive and will not damage the glass. FLAMMABLE LIQUIDS: Never use gasoline, gasoline-type lantern fuel, kerosene, charcoal lighter fluid, or similar liquids to start or freshen up a fire in the heater. Keep all such liquids well away from the heater while it is in use. SMOKE DETECTOR: Smoke detectors should be installed and maintained in the structure when installing and operating a pellet burning appliance. OPERATION: The ash pan and door must be closed securely for proper and safe operation of the pellet stove. Also ensure all gaskets on the door are checked and replaced when necessary. KEEP ASH PAN FREE OF RAW FUEL. DO NOT PLACE UNBURNED OR NEW PELLET FUEL IN ASH PAN. A fire in the ash pan may occur. INSTALLATION: Be sure to maintain the structural integrity of your home when passing a vent through walls, ceilings, or roofs. It is recommended that the unit be secured into its position in order to avoid any displacement. DO NOT INSTALL A FLUE DAMPER IN THE EXHAUST VENTING SYSTEM OF THIS UNIT. DO NOT CONNECT THIS UNIT TO A CHIMNEY FLUE SERVING ANOTHER APPLIANCE. FRESH AIR: Outside Fresh Air connection is optional. Must be connected to all units installed in Mobile and Air Tight Homes (R2000) or where required by local codes. Consider all large air moving devices when installing your unit and provide room air accordingly. Limited air for combustion may result in poor performance, smoking and other side effects of poor combustion. If you have any questions with regards to your stove or the above-mentioned information, please feel free to contact your local dealer for further clarification and comments. SINCE SHERWOOD INDUSTRIES LTD. HAS NO CONTROL OVER THE INSTALLATION OF YOUR STOVE, SHERWOOD INDUSTRIES LTD. GRANTS NO WARRANTY IMPLIED OR STATED FOR THE INSTALLATION OR MAINTENANCE OF YOUR STOVE. THEREFORE, SHERWOOD INDUSTRIES LTD. ASSUMES NO RESPONSIBILITY FOR ANY CONSEQUENTIAL DAMAGE(S).
Operating Instructions
automatic Safety featuReS:
Your pellet Stove has the following safety features: A. The stove will shut off when the fire goes out and the exhaust temperature drops below 120F (49C). B. The stove has a high temperature safety switch. If the temperature on the hopper reaches 200F (93C), the auger will automatically stop and the stove will shut down when the exhaust temperature cools. If this happens, call your local dealer to reset the 200F (93C) high limit switch. ALSO FIND THE REASONS WHY THE UNIT OVERHEATED. C. The unit has a convection fan control over-ride. This function causes the convection fan to reach its full speed when the temperature at the back of the firebox reaches 160F (71C). This is a normal safety feature of your unit. To compensate for the fan cycling action that may occur, turn up the blower control proportionately to the heat output. D. If the power goes out, the unit will stop running. When the power comes back on, the stove will not restart unless the exhaust temperature is still above 120F (49 C).
SliDeR/DamPeR Setting:
The slider/damper must be set at time of installation. This is used to regulate the airflow through the pellet stove. The slider damper is located behind the left side panel. To open the left side panel, undo the one screw located in the upper front corner of the cabinet side SPECIAL NOTES: The easiest way to make sure that an efficient flame is achieved is to understand the characteristics of the fire. A tall, lazy flame with dark orange tips, requires more air Open slider (pull out) slightly. A short, brisk flame, like a blowtorch, has too much air Close slider (push in) slightly. If the flame is in the middle of these two characteristics with a bright yellow/orange, active flame with no black tips then the air Figure 1: Efficient Flame. is set for proper operation Pellet quality is a major factor in how the Pellet stove will operate. If the pellets have a high moisture content or ash content the fire will be less efficient and has a higher possibility of the fire building up and creating clinkers (hard ash build-up). If the fire should happen to go out and the Dial-A-Fire has been set on the lowest setting, the Slider Damper should be pushed in slightly, decreasing the air in the firebox or the Dial-A-Fire and Auger Trim can be turned up slightly. If, after long periods of burning, the fire builds up and overflows the burn pot or there is a build up of clinkers, this would be a sign that the pellet quality is poor, this requires more primary air, the slider damper must be pulled out to compensate. Pulling the slider damper out gives the fire more air.

Operating Instructions
oPeRating youR Pellet Stove:
1. Check and fill hopper with pellets. 2. Make sure unit is plugged into a working outlet. 3. Switch the power ON by pushing the start-up switch once only. 4. Turn knob B to the 12 oclock position. (Lower grade pellets may need a higher setting on the feed rate). NOTE: Unit will take longer to light if the hopper has been completely emptied or is the first fire up. 5. Wait until the fire is established, then turn Knob B to the desired heat output. The stove may not be able to burn in the BLUE ZONE if poor quality wood pellets are being used. Adjust the slider-damper to the appropriate setting (see Slider/damper Setting section. 6. If the stove should shut off after fifteen (15) minutes and there is still a fire in the firebox press the start-up switch once more. If the fire went out, return to step 2 and re-light the stove. KNOB A: Fan Controller. By adjusting the knob you will Figure 3: Dial-A-Fire control panel. vary the rate of airflow into the room by varying the speed of the convection blower. When you first start the stove, it should be placed in the OFF position in order to heat the unit as quickly as possible. Once the room has come up to temperature, the control may be set to a comfortable level. *Note: The convection blower may cycle to high automatically depending on the setting of knobs A and B. This is a normal safety feature of the unit. SPECIAL NOTES: The flashing green light corresponds to the auger feed rate. KNOB B: Dial a Fire Heat Output Knob. This knob controls the amount of heat output. The dial has a scale with the blue zone representing the coolest setting of the stove, and the red zone representing the hottest setting. The scale on knob B represents a range, not exact at times or fuel quantities. Wood pellets of differing quality may affect the performance of the stove. If the stove has trouble operating at either end of its range, turn the heat output knob back slightly.
INSIDE FIREBOX (weekly) For bi-weekly clean out, ash may be removed from behind the steel plates by rotating the circular cover to allow vacuuming behind the plates. ASH PAN AND DOOR GASKETS (weekly) After extended use the gasket may come loose. To repair or replace this, glue the gasket on, using hightemperature fiberglass gasket glue available from your local ENVIRO dealer. This is important to maintain an airtight assembly.
The EF3 pellet stove inserts ash pan is located behind the lower grill. HEAT EXCHANGER TUBES (2-3 days) The handle for the heat exchanger cleaning rod is pointed out in Figure 5. This handle is to be pulled back and forth a few times (ONLY WHEN THE UNIT IS COLD) in order to clean away any fly ash that may have collected on the heat exchanger tubes. As different types of pellets produce different amounts of ash, cleaning of the tubes should be done on a regular basis to enable the unit to run efficiently. FRESH AIR INTAKE (season) Inspect periodically to be sure that it is not clogged with any foreign materials. EXHAUST PASSAGES (season)
For bi-weekly clean out, ash may be removed from behind the steel plates by rotating the circular covers located behind the right and left side panels. Loosen the screw on the disks and open, this will allow vacuuming behind the firebox liners plates. Removal of the firebox backing for bi-annual cleaning: Remove the top baffle. Lubricate and then remove the seven (7) screws that hold the brick liner in place. Tilt the top of the brick panel towards the firebox opening and remove from the firebox Remove the top rod by first removing the screw that holds it in place, then slide the rod sideways Pull the side panels into the center of the firebox, then out Pull the center panel out. Clean and vacuum all passages thoroughly.

Figure 16: Use in conjunction with Table 1 for allowable exterior vent termination
3. Termination must exhaust above the inlet elevation. It is recommended that at least five feet of vertical pipe be installed outside when the appliance is vented directly through a wall, to create some natural draft to prevent the possibility of smoke or odor during appliance shut down or power failure. This will keep exhaust from causing a nuisance or hazard from exposing people or shrubs to high temperatures. In any case, the safest and preferred venting method is to extend the vent through the roof vertically. 4. Distance from the bottom of the termination and grade is 12 (30 cm) minimum. This is conditional upon the plants and nature of grade surface. The exhaust gases are hot enough to ignite grass, plants and shrubs located in the vicinity of termination. The grade surface must not be lawn. 5. If the unit is incorrectly vented or the air to fuel mixture is out of balance, a slight discoloration of the exterior of the house might occur. Since these factors are beyond the control of Sherwood Industries Ltd, we grant no guarantee against such incidents. NOTE: Venting terminals shall not be recessed into walls or siding. 15

outSiDe fReSh-aiR connection:
A Fresh-air intake is strongly recommended for all installations. Failure to install intake air may result in improper combustion as well as the unit smoking during power failures. The inlet to the intake must be below and a minimum of 12 (30cm) away from the unit exhaust outlet. Outside fresh air is mandatory when installing this unit in airtight homes and mobile homes. When connecting to an outside fresh air source, do not use plastic or combustible pipe. A 1 minimum (42 mm) ID (inside diameter) steel, aluminum or copper pipe should be used. It is recommended, when you are installing a fresh air system, to keep the number of bends in the pipe to a minimum.

Do not forget to place high temperature silicone around the pipe that passes through the thimble. 11. Install a vertical pipe, or if all requirements for direct venting are met, install vent termination. The stainless steel cap termination manufactured by the vent manufacturer is recommended. However, when the vent terminates several feet above ground level and there are no trees, plants, etc. within several feet, a 45 elbow can be used as termination. The elbow must be turned down to prevent rain from entering. NOTE: It is recommended that horizontal through wall installations have 3 to 5 feet (91 to 152 cm) of vertical pipe in the system to help naturally draft the unit in the event of extreme weather or a power outage. Some horizontal through wall installations may require a T and 3 to 5 feet (91 to 152 cm) of vertical pipe outside the building to help draft the unit. This may be required if a proper burn cannot be maintained, after the stove has been tested and the airflow set. This is due to the back pressure in the exhaust caused by airflow around the structure. Follow vent manufacturer guidelines for installation of venting. High temp Sealent must be used when connecting vent pipe to the units starter pipe. Improper seals at the vent joints may cause combustion by-products to leak into the room where installed - seal as required.

SliDeR/DamPeR inStallation:
This is used to regulate the airflow through the pellet stove. 1. Remove the slider rod (short rod with knob and nuts) from their package and open the left side panel. 2. Remove the knob and outer nut from the knob. Push the rod through the hole in the slider. Place the lock nut on the rod and tighten, leaving a 1/32 (1 mm) gap between the slider and the other nut. 3. Make sure the slider moves freely. Close the side panel and tighten screws after placing the rod through the panel. Screw the knob onto the slider. A Qualified Service Technician or Installer must set the Slider Damper. Taking a reading of vacuum pressure inside the firebox with a magnehelic gauge can be used to set the slider for best combustion. The slider damper should be set only on a hot stove (operating for 30 minutes or more) by placing a Magnehelic Pressure Gauge in the firebox (test port is located in the center of the stove just below the door opening). The best settings are a reading of 0.12 to 0.13 inches of water column (30 Pa) on the high fire setting. Some fuels may require higher or lower settings. The reading can be taken from the (3 mm) hole located on the front of the unit below the door and behind the magnetic ash lip.

Troubleshooting
DO NOT: Service the stove with wet hands. The stove is an electrical appliance, which may pose a shock hazard if handled improperly. Only qualified technicians should deal with possible internal electrical failures. Remove any screws in the firebox without first lubricating them with penetrating oil. WHAT TO DO IF: 1. The stove will not start. 2. The stove will not operate when hot. 3. The exhaust blower will not function normally. 4. The convection blower will not function normally. 5. Ignitor - Everything else in the stove operates but the ignitor will not light the pellets. 6. The auger motor does not function normally. 7. The Dial-A-Fire has no effect on the fire. 8. The 200F (93C) high limit temperature sensor has tripped. 9. The stove will not shut off. 10. The stove keeps going out. *NOTE: All troubleshooting procedures should be carried out by qualified technicians or installers. 1. The stove will not start. Make sure the stove is plugged in and the wall outlet is supplying power. With the stove unplugged, examine all connections. Make sure they are firmly connected and that there are no exposed wires touching the stove (except the chassis ground wire). Check the continuity and placement of connections against the Wiring Diagrams in this manual. If the unit still does not start after trying the below, contact your local dealer for service. Push the Start-up switch. If the stove fails to start, unplug the unit and open the hinged side panels (held tight with two screws). Ensure that the connections to the fifteen (15) minute start-up timer are correct. Attempt to bypass the switch by inserting a jumper wire between the red and white wires that attach to the switch. Plug the stove back in. If the stove starts, replace the switch. If this fails, replace the fifteen (15) minute start-up timer. Caution: Installation of a new start-up timer without checking the ignitor resistance may cause another failure to the new start-up timer due to a short in the ignitor. The proper resistance through the ignitor should be 30 to 50 3. 2. The stove will not operate when hot. Check the hopper for fuel. Incorrect air damper setting - Excessive air may consume the fire too quickly before the next drop of fuel, leaving completely unburned fuel in the burn pot liner. Insufficient air will cause build up, further restricting the air flow through the Burn Pot Liner. This in turn will cause the fuel to burn cold and very slowly. Fuel may build up and smother the fire. (NOTE: Unit may require a change to the vent system or installation of fresh air to correct Air to Fuel ratio problems). Combustion Blower failure - The Combustion Blower is not turning fast enough to generate the proper vacuum in the fire box. Visual Check is the blower motor turning?

Troubleshooting
Check Vacuum levels in the exhaust channel by bypassing the Vacuum Switch, then remove the Vacuum hose from Vacuum Switch. Check exhaust vacuum readings by placing the open end of the Vacuum Hose on a Magnehelic Gauge (readings must be above 0.10 W.C. on low fire). Note: If the motor fails to reach a 0.10 W.C. reading, then replace the Combustion Blower. Poor Quality Fuel Insufficient energy in the fuel to produce enough heat to keep the stove burning or operational. Exhaust Temperature Sensor failure Bypass sensor located on Exhaust Blower. If stove now operates properly, the unit may require cleaning or a new sensor. Contact your local dealer for service. The unit may require cleaning. Contact your local dealer for service. Unplug the stove, open the left side panel. Jump the two (2) brown leads that are attached to the 140F (60C) temperature sensor. If the stove operates replace the 140F (60C) sensor. 3. The exhaust motor will not function normally. Open the left side access panel; check all connections against the wiring diagram. If all the connections are verified and the exhaust blower does not function at all, tap lightly on the exhaust blowers motor end cap, this may loosen a tight motor. Apply 115 V AC directly to the exhaust blower. If the motor does not run, replace the blower. If the motor runs, have your dealer check the harness. See 2. The stove will not operate when hot. section. Contact your local dealer for service. 4. The convection blower will not function normally. Clean all grill openings at the back and below unit. Check all the connections between the controller, switch, and the convection blower against the wiring diagram. If the convection motor will not run, apply 115 V AC to the motor directly. If the motor runs, replace the fan controller. If the motor does not run, the convection blower has failed. Replace the blower. If the convection blower runs on high at all times (no control with the fan controller), check the connections from the 160F (71C) sensor (located on the upper left side of the firewall) and convection fan controller to the blower. Disconnect one of the wires from the sensor; if control of the convection blower returns to the fan controller, replace the sensor. If the motor is still on high, re-connect the sensor and replace the convection fan controller. 5. Ignitor - Everything else in the stove operates but the ignitor will not light the pellets. Check the burn pot liner placement. Make sure the burn pot liner is up tight and square to the ignitor tube (by pushing the burn pot back against the ignitor tube). Check all the electrical connections on the 120F (49C) temperature sensor located on the exhaust channel. Place a jumper wire between the two leads on the 120F (49C) temperature sensor. If the ignitor works, replace the sensor. Check to see if the exhaust blower is operating. If not, contact your local dealer for service. If the ignitor does not work, replace it. NOTE: The ignitor should be bright orange in color. If not, replace the ignitor.

Troubleshooting
6. The auger motor will not function normally. If the Auger gear box does not turn but the motors armature does try to spin then the auger is jammed. Try to break apart jam by poking at the jam through the drop tube. If this fails then empty the hopper and remove the Auger Cover **Remember to re-seal the cover after installation** Make sure the exhaust blower is operating. Check the condition of the vacuum hose (located on the left side of the stove). It should not be cracked or torn and should be installed on the top air inlet tube on the vacuum sensor. Check the manual reset button on the 200F (93C) temperature sensor. If this sensor has been tripped, check for the cause of the over-heating before pushing the red button in. Check auger for movement. If the auger still does not work, then apply 115 V AC directly to the auger motor. If the auger motor does not work, replace it. By pass the 200F (93C) temperature sensor with a jumper wire; check the auger. If the auger works, replace the sensor. Check the vacuum sensor by placing a jumper wire between the blue wire and the black wire that are attached to the sensor. If the auger works, test to see if the exhaust blower is producing enough vacuum. To test the exhaust vacuum, place a magnehelic gauge in the sensor end of the vacuum tube. It should read 0.5 W.C. If the reading is good, replace the vacuum sensor. If none of the below work contact your local dealer for service. Make sure the dial-a-fire is turned on. Unplug the stove and open the side and back panels. Check all the connections to the auger motor, auger dial-a-fire, vacuum sensor, 200F (93C) temperature sensor and the timing control module against the wiring diagram in this manual. Check the voltage across the load pins of the timing module. It should be around 1 V to 2 V, cycling to line voltage during an auger pulse. If not, replace the timing control module. If the auger motor still does not work, then attempt to by-pass the auger dial-a-fire control by removing the leads from the timing control modules second delay pins and placing a jumper across the pins. If the auger now cycles very quickly, test the dial-a-fire potentiometer. If the auger did not cycle, replace the timing control module. To test the dial-a-fire potentiometer, the potentiometer should have a range of 68K to approximately 850 K ( 10%). If the range is not close, replace the potentiometer. 7. The dial-a-fire has no effect on the fire (Timer Control Only). Make sure all connections to the timer control module are secure. Perform a resistance test to the dial-a-fire potentiometer by placing the two (2) test leads from a multimeter into the leads of the potentiometer. The potentiometer should have a range of 68K to approximately 850 K ( 10%). Potentiometer Readings: Full counter-clockwise (switched off) = open circuit, overload or infinite resistance Low fire ...............................800 K to 900 K High fire ..............................68 K to 82 K If the range is not close or does not vary then replace the potentiometer.

Troubleshooting
8. The 200F (93C) high limit temperature sensor has tripped. Reset the sensor and determine the cause - was it convection blower or 160F (71C) temperature sensor failure? Bypass the 160F (71C) sensor. Does the convection blower come on high? If no, replace the blower. 9. The stove will not shut off. If the unit will not shut off, ensure that the thermostat (if equipped) is turned down below the room temperature (thermostat mode in the ON / OFF position). Disconnect one of the brown wires from the exhaust temperature sensor. If the unit continues to operate, contact your local dealer for service. Check the connections to the 140F (60C) temperature sensor, start-up switch and the start-up timer against the wiring diagram. Check the 140F (60C) temperature sensor by removing one of the brown wires from the sensor. The unit should shut down right away as long as the start button was not pressed within 15 minutes of this test. If the stove shuts down within fifteen (15) minutes, replace the 140F (60C) sensor. If the stove does not shut down within fifteen (15) minutes, test the switch. To test the switch, the stove must be cold. Pull the plug, then plug the stove back in. If it fails to start, replace the switch. 10. The stove keeps going out If the stove goes out and leaves fresh unburned pellets or cigarette-like ashes in the burn pot liner, the fire is going out before the stove shuts off. Check to see that the Slider / Damper is in the correct position. Turn the Dial-a-Fire up slightly (poor quality pellets will require slightly higher settings). If the stove goes out and there are partially burned pellets left in the burn pot liner, the stove has shut down due to a lack of air, exhaust temperature, or power failure. Adjust the Slider / Damper. Check to see if the stove needs a more complete cleaning. Did the power go out? Contact your local Dealer for service. Turn the Dial-a-Fire up slightly (poor quality pellets will require slightly higher settings). If the stove goes out and there are no pellets in the liner, the auger is stopping. See The auger motor will not function normally and The exhaust blower will not function normally.
