appliance was firing prior to the power failure occurring it will attempt
to recover the flame if possible. If flame recovery is not possible the
boiler will extinguish and attempt to re-ignite. Where this happens

Setting your time clock

Your heating system may be equipped with a time

clock so that you can set your central heating
to come on when you want it. You may have to
make a few changes to your time clock settings
when you switch to a wood pellet boiler.

When the signal for heat is sent the boiler begins

a process to light a flame before any heat is
generated.

To offset this delay we recommend setting your

time clock to come on earlier, the amount of time
you would want to adjust by will vary based on a
few different factors but once set should mean a
reliable heat source when you expect it.
