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 Outside 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, non-combustible,
heat resistant material up to 350°F (177°C). Cut the
pipe to the required length for your installation.
• Phillips head screw driver
• Silicone sealant
• Non-combustible pedestal sealing material if installing
with the Alternate Floor configuration.
• Drills and saws necessary for cutting holes through the
wall or flooring in your home
1. Rear: Remove the access cover on the back of the
pedestal and discard (Figure 36.2).
2. Using a #2 Phillips screw driver attach the flex adapter
to the appliance using 4 screws. Secure with Wire Tie
(Figure 36.1).
3. Floor: For standard floor installation remove the
circular "knock-out" in the base of the pedestal.
4. Floor & Rear Installation: Cut a 4 inch (102mm) hole in
outside 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 36.1.
If that is the case, follow the instructions for a rear
installation install the flex pipe to the rear of the pedestal
and remove the circular "Knock-Out" in the base of
the pedestal. You must seal off the pedestal with non-
combustible material (not supplied). The goal is to seal the
pedestal so no room air can leak into the pedestal and to
seal for cold air infiltration (Figure 36.2).
WARNING
Fire Risk.
Asphyxiation Risk.
Do not draw outside combustion air from:
• Wall, floor or ceiling cavity
• Enclosed space such as an attic or garage
• Close proximity to exhaust vents or chimneys
Fumes or odor may result
WARNING
Asphyxiation Risk.
Outside air inlet must be located to prevent
blockage from:
• Leaves
• Snow or ice
• Other debris
Block may cause combustion air starvation
Smoke spillage may set off alarms or irritate
sensitive individuals.
WARNING
Asphyxiation Risk.
Length of outside air supply duct shall NOT
exceed the length of the vertical height of the
exhaust flue.
• Fire will not burn properly
• Smoke spillage occurs when door is opened
due to air starvation.
Sealing Material
(not supplied)
Remove Circular "Knock-Out" in Base of
Pedestal and Seal the Pedestal with
Non-combustible Material.
