A. Outside Air Attachment
Outside Air Kit #1-00-774280 (sold separately) must
be used for attaching outside air to the insert. This kit
contains a 3" stub and gasket to mount to the frame,
and the outside air adapter which secures to the insert
body. The outside air intake connection will seal to the
mounting frame, just like the exhaust does. Follow the
instructions included in the kit to ensure proper instal-
lation.
1. Make a determination of where you want to draw
the outside air from. Here are a few options.
a. Punch a hole through the rear of the
fireplace and exterior wall. Rigid pipe or flex
pipe could be used.
b. Use the chimney or chase as a conduit for
outside air. The exhaust liner must be run
the full length of the flue. When creating
your steel plate to seal the damper area,
Make another 3 inch hole for the outside air
pipe. Install a short run of pipe from the
mounting frame through the sealing plate.
Then install the chimney top extension kit,
item #1-00-674104 at the top of the chimney.
This is slotted to allow fresh air into the
chimney or chase.
2. Secure the outside air supply pipe to the stub on
the mounting frame using a minimum of two fas-
teners.
3. If running the supply pipe direct, install the outside
air cover weldment #1-10-09542 to keep birds or
rodents from entering the supply pipe.
4. Keep the intake a minimum of 4 feet (1.2 m) below
the exhaust termination.
CAUTION!
Never draw outside combustion air from:
• Wall, floor or ceiling cavity.
• Enclosed space such as an attic or garage
The image at left shows the use of the chim-
ney for outside air supply. Also shown is the
Chimney intake extension on the top of the
chimney. It is slotted to allow fresh air into
the flue. Be sure to use the proper flashing
and vent cap to prevent rain from entering the
chimney flue.
The image below demonstrates bringing the
outside air in through a hole cut through the
rear of the fireplace and external wall. With
this method, a screen is necessary to prevent
birds or rodents from entering.
