Combustion Air
Consult local building codes regarding combustion air supply.
Intake or combustion air can be supplied to the Insert in
one of two ways:
1) Outside air (O/A) supply: Remove cover from ash clean
out in existing fireplace. Place a rodent screen in place of
the cover. Install the Insert as described in the installation
section, making sure not to cover the opening of the air
inlet. When installation is complete, seal surround to
fireplace and anywhere else air may enter. This will ensure
combustion air is drawn from outside the house and into
the 9" x 2" intake at the lower rear of the appliance.
2) Room air supply: Install the Insert as described in the
installation section. When the installation is complete
do not seal surround to fireplace. This will allow enough
combustion air to enter the fireplace cavity and the Insert.
The knockouts in the casing sides and the O/A cover
can be removed to supplement air supply (Fig.30 & 31).
Once removed, combustion air is drawn from the room
into the lower front of the Insert.
Removal: The O/A cover should be removed prior to
installation. For better access, tip the Insert onto its back.

1. Using a 5/16" wrench, remove the screw securing the
O/A cover to the firebox (Fig. #29 & 30).
This unit is not designed to be operated with the firing door
open. In addition to the obvious hazard of sparks landing on
combustibles, an open fire door will cause the heater to draw
air from the living space and possibly cause suffocation.
The living space around the heater must be well ventilated
with good air circulation. Anything that may cause a negative
pressure can cause gases or fumes to be pulled into the
living area.
