Final stage:
The nal stage of burning is the charcoal stage. This occurs
when the ammable gases have been mostly burned and
only charcoal remains. This is a naturally clean portion of
the burn. The coals burn with hot blue ames.
It is very important to reload your replace while enough
lively hot coals remain in order to provide the amount of heat
needed to dry and rekindle the next load of wood. It is best
to open the air control for a short while .
This livens up the coalbed. Open door slowly so that ash or
smoke does not exit replace through opening. You should
also break up any large chunks and distribute the coals so
that the new wood is laid evenly on hot coals.
Fireplace operation does require air. Do not take air from
other fuel burning appliances which can result in improper
venting (smoking) or air dilution. Always provide adequate
makeup air.
IMPORTANT! As you move the Combustion Air Control
to the RIGHT, you will feel resistance about three-fourths
of the way. You must move past that resistance approxi-
mately 3/4 in. (19mm) to fully engage the Automatic
Combustion Control (ACC) sytstem.
With the Automatic Combustion Control system that is on this
replace, you can set the replace to high (slide the Combus-
tion Air Control all the way to the right), start the re, and then
move the Combustion Air Control to the desired burn level.
The replace will automatically go to that level once the re
is fully established. This allows for less interaction with the
re by the homeowner and more efcient use of fuel while
maintaining the desired heat output.
After the replace has been in operation for a period of time,
and is warmed up; you may prefer to not activate the ACC
when reloading fuel. if you do not slide the Combustion Air
Control all the way to the right, the ACC will not be activated.
The lever located to the left of the Combustion Air Control
is the ACC OVERRIDE and may be used to override the
setting of the Combustion Air Control. If the ACC has been
activated and burn rate needs to be slowed, move the
lever to the LEFT and position Combustion Air Control at
the preferred setting. To close the air supply for an over
re situatution or to slow the burn rate down immediately,
slide the lever to the LEFT and also slide the Combustion
Air Control all the way to the left.
