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.
