The CF780 is designed to have optional outside air. The control for the outside
air is located on the left side beyond the door rail (see Diagram). This control
closes the damper when not in use.
You need to fully open the door and the firescreen to have access to the
external air control.
To minimize the risk of injuries or burns, do not to touch the external
air control and the surrounding parts with your bare hands while the
fireplace is hot. They may be hot enough to burn.
When the round portion of the external air control is pushed to the right,
the outside air damper is open. When it is pushed to the left, the outside air
damper is closed. Use your door handle or a gloved hand to open or close the
air control when the fireplace is hot.
Outside Air Control Location
Pull lever up and slide
over—to open/close
Do not use force to move the control, it should move freely about its pivot point. A spring keeps it open or closed, it will not change position by itself.
Even though the fireplace can be operated with the outside air damper closed, we recommend always using outside air for combustion when burning the fire-
place with the door closed. Outside air is generally colder and denser it will help keep your glass cleaner. In some cases this fresh air will also help compensate
for negative pressure problems within the house; however it will not prevent the fireplace from smoking in a severely depressurized house.
We also recommend using outside air for combustion when burning the fireplace with only the firescreen closed. It will help reduce the depressurization of
the house caused by burning the fireplace with the firescreen.
This control should be closed when the fireplace isn’t burning to prevent cold air infiltration. It is sealed with a gasket.
