ОГОҲ
The gas water heater requires a sufficient source of clean air for combustion and ventilation. Without enough air, your water heater may not function properly and may cause excessive and abnormal carbon monoxide causing poisoning or death.

Before installing the water heater, you must be sure to supply the required amount of air to the water heater and any other gas equipment in the same area and provide adequate air for combustion and ventilation. If you are not sure of the correct way to supply air to your water heater, please consult a professional. Check chemicals: The air used for combustion and ventilation must be clean and free of corrosive chemicals. If corrosive chemicals such as sulphur, fluorine or chlorine are present, the water heater must be vented directly. Failures due to these corrosive chemicals are not covered by the warranty. WARNING! In all cases, ensure that there are no corrosive chemicals in the air intake. The presence of such chemicals at the air inlet can result in death, personal injury or property damage. Examples of locations where external air is required due to chemicals include:

Beauty salon
Photo Processing Lab
indoor swimming pool
Laundry, hobby or craft room
Chemical storage such as aerosol sprays, detergents, bleaches, cleaning solvents, gasoline, air fresheners, paint and varnish removers, and refrigerants should not be stored or used near water heaters. Does

your installation space have enough combustion air? It is recommended that all installations be ventilated with outdoor air. Even if the water heater is installed in a large open room in a house, outdoor air is usually required because the modern home is very tightly sealed and usually does not provide enough air for the water heater. However, when installed in a large indoor space, it provides enough air without external ventilation. If you are not sure if there is adequate ventilation in your installation location, please contact your local gas company or agent for a safety check or simply vent the water heater.

The instructions below will help determine if the water heater can be installed without outdoor ventilation. Calculate the total BUT/h rating of all equipment. To calculate the required combustion air and ventilation, add the BTU/h rating of all gas appliances (eg water heaters, furnaces, dryers) in the same area. Do not include appliances that are directly ventilated. See the example below. The BTU/h rating of your water heater is on the nameplate. The BTU/h rating should be on the rating plate of the other gas appliance. If you are unsure of the BTU/h rating, contact the manufacturer or have qualified personnel to determine the ventilation requirements. Note: If you are replacing an old water heater with a BTU/h rated higher water heater, the amount of ventilation required may be greater.

Exampле:

Асбоби газ	BTU/h rated
Обгармкунаки газ	170000
печка	75000
Хушккунак	20000

Calculating the amount of air in a room The air demand depends on the size of the room.
Room volume (ft3) = floor area (ft2) x ceiling height (ft)
If there are large objects in the room (such as refrigerators, stoves, cars), subtract their volume.
You can better estimate the available air. Air volume = room capacity – object capacity

Шарҳ: Adjacent rooms with permanently open doorways can be counted as part of the calculation. Calculate the amount of air required to install in an unrestricted attic, with a water heater in the garage or space requiring a space of at least 50 ft3 (1. 42 m3 ) total input of all gas appliances in the same area per 10,000 BTU / h the amount. Required air volume ( ft3 ) = total energy level of the equipment (btu / h) x 50 ft3 / 1000 (btu I h) Example: (294,000 / 1000)x50 = 14,700ft3 If the air volume in the room is less than the required air volume, the water heater must be ventilated or lifted directly.

Provide a permanent external air opening to draw in enough air. If you want to provide combustion air for outdoor ventilation, go to “Using Outdoor Ventilation lnstallation”.lf the amount of air in the room is greater than the amount of air required, the water heater can be installed without external ventilation. However, the impact of the exhaust fan must be considered. Exhaust fans can affect the amount of combustion air available in your home. Electric appliances such as stoves, whole house fans and dryers will let the air out of the house. If the air they pump out is faster than it can be replaced, your water heater may not have enough oxygen to properly ignite. It may also result in back drafting, ie when negative air pressure is drawn back through the chimney or appliance vents. These events can cause unsatisfactory water heater performance. The best solution is to direct the water heater directly to vent or install a sufficient number of supplementary vents.

Installation for outdoor ventilation is recommended for outdoor air ventilation and is required for most installations. There may be adequate ventilation or you may need to increase ventilation. Supplying outside air to a water heater typically requires two openings. One opening must be 12 inches (305 mm) from the floor and the second opening must be 12 inches (305 mm) from the ceiling. Although a single opening is not preferred, if a minimum free area is determined according to Table 1, a single opening can be used to enter the outside air. When using air from another room for ventilation, two openings must be used. The outside air can be taken out of the crawling space or attic, leading to the outside and fully ventilated. You can use vertical or horizontal pipes.
Several types of ventilation can be used to determine the type of ventilation. The various options are listed below.

Directly to the outdoors
Қубури амудӣ
Horizontal pipeline
Single opening (not recommended; must be at least 100 in2 (6.5 cm2). Not applicable to confined spaces of less than 50 ft3 (1.42 m3) per 1000 BTU/ hour or from another The air in the room.)
From a larger room in the room (not recommended – refer to “Calculate the amount of air in the room” above to determine if the total volume of the room is sufficient).

The minimum free zone vents required to define each vent are sized depending on the total BTU/ h rating of all appliances in the space (using the “before” calculation) and the type of vents used. Table 1 provides the minimum free area for each vent, depending on the type of ventilation. Calculating the minimum size of the vents and piping. The venting cross-sectional area required to provide a free area depends on the covering on the vent. Typical vents use shutters or grilles to protect the opening. The blinds or grill itself block some free areas, so the openings may need to be larger to meet the minimum free area requirements. Calculate the required cross-sectional area using the following formula: Cross-sectional area = minimum required free area percentage of free area covered (in decimals -Eg, 60 % = 0.6) For example, an opening of 100 in2 is required.

(645cm2) installation area if Use metal blinds rated at 75% free zone (100in2+ 0.75 = 134in2), then A 134 inch 2 (865 cm2) opening is required. If you don’t know the % available area of the blinds or grill, use the following values:

For wooden shutters or grilles: 25%
For metal shutters or grilles: 75% follow these rules to ensure that the vents and ducts provide adequate airflow:
Each vent must be no less than 1 00in2 (645cm2).
The pipe must have the same cross-sectional area as the free area of the opening.
The minimum size of a rectangular pipe must not be less than 3 inches (76 mm).
All screens must have a grid of 1/4 inch or larger.
The removable blinds must be locked open or interconnected to automatically open during operation.
Keep blinds and grills clean and free of debris or other obstructions. Check that the air source is clean and free of chemicals. The air used for combustion and ventilation must be clean, free from corrosive or flammable chemicals. Failures caused by corrosive chemicals in the air are not covered by the warranty. The combustion air must be free of sulfur-containing, acid-containing chemicals such as fluorine and chlorine. Make sure that these chemicals are not in the air at the vents.
