9 Appliance Set-up
A. Outside Air Kit Installation
A source of air (oxygen) is necessary in order for combustion to take place. Whatever combustion air is consumed by the fire must be replaced.
Air is replaced via air leakage around windows and under doors. In homes that have tightly sealed doors and windows, an outside air source is highly recommended. An optional Out- side Air Kit is available.
Included in kit: Termination cap, (2) wire ties, flex adapter, and fasteners
Items Needed for Installation (not supplied)
•4 inch flex aluminum pipe, or if using alternate material, then it shall be made from durable,
•Phillips head screw driver
•Silicone sealant
•
•Drills and saws necessary for cutting holes through the wall or flooring in your home
Instructions
1.Rear: Remove the access cover on the back of the pedestal and discard. Figure 39.2.
2.Using a #2 Phillips screw driver attach the flex adapter to the appliance using 4 screws. Secure with wire tie. Figure 39.1.
3.Floor: For standard floor installation remove the circular
4.Floor & Rear Installation: Cut a 4 inch (102mm) hole in out- side wall or floor to accommodate outside air piping. Use 4 inch (102mm) aluminum metal flex or rigid piping to directly connect outside air to appliance intake. Use the supplied termination cap with a rodent screen. Seal between the wall (or floor) and the pipe with silicone to prevent moisture penetration.
5.Floor Installation Alternative: In some instances you may not be able to install the flex pipe as show in
Figure 39.1.
If that is the case, follow the instructions for a rear installation install the flex pipe to the rear of the ped- estal and remove the circular

Outside air inlet must be located to prevent blockage from leaves, snow, ice or other debrs. Blockage may cause combustion air starvation. Smoke spillage may set off alarms or irritate sensitive individuals.
The length of the outside air supply duct shall NOT exeed the length of the vertical height of the exhaust flue.
•The fire will not burn properly and their will be smoke spillage when the door is opened due to air starvation.
