K. 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 needed. An
optional Outside Air Kit is avail
able.
Items Needed for Installation (not supplied)
• Phillips head screw driver
• Outside air shield
• Wire ties
• Plastic outside air vent
• Flex / Rigid pipe
• Silicone sealant
• Drills and saws necessary for cutting holes through
the wall or flooring in your home.
1. Remove all materials from packing box.
2. Using a #2 Phillips screw driver attach the flex adapter to
the appliance using 4 screws. Figure 5.12 & 5.13.
3. Floor & Rear Installation: Cut a 3” (76 mm) hole in outside
wall or floor to accommodate outside air piping. Use 3”
(76 mm) 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.
