2. ACC Override
The ACC OVERRIDE lever is located behind the lower
access panel (See Figure 3.4) and may be used to over
-
ride the setting of the automatic combustion air control.
If the ACC has been activated and burn rate needs to
be slowed, remove the bottom access panel by lifting
it up and pulling it off. To close down the air supply for
an over-fire situation or to slow the burn rate down im
-
mediately, slide the linkage to the left. See Figure 3.5.

1. Automatic Combustion Control (ACC)
The automatic combustion control system allows you to
set the fireplace to high (slide the combustion air control
all the way to the right), start the fire, and then move
the combustion air control to the desired burn level.
The fire will automatically go to that level once it is fully
established. This allows for less interaction with the fire
by the homeowner and more efficient use of fuel while
maintaining the desired heat output.
After the fireplace becomes hot, 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.
NOTICE
:
If reloading a bright, hot coal bed for longer
(low) burn time, setting the ACC may not be required.
Burn dry, well seasoned wood.
NOTICE
:
To establish your settings, always begin with
the air control all the way to the left to CLOSED and then
move it to the right for your desired setting.
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
approximately 1 in. (25mm) to fully engage the automatic
combustion control (ACC) system.

A source of air (oxygen) is required in order for com-
bustion to take place.
1.
Before lighting the fire open the bottom access panel
by lifting it up and pulling it off.
2.

the handle up and pull out to open the door (push-
ing the handle in will close the door).
3. Reinstall the bottom access panel.
3. Outside Air
