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 installation.
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 fasteners.
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.
The image at left shows the use of the
chimney 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.
