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
Instructions
1. Rear: Remove the access cover on the back of the
pedestal and discard (Figure 38.2).
2. Using a #2 Phillips screw driver attach the flex adapter
to the appliance using 4 screws. Secure with Wire Tie
(Figure 38.1).
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 38.1. 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
38.2).
Sealing Material
(not supplied)
Remove Circular "Knock-Out" in Base of
Pedestal and Seal the Pedestal with Non-
combustible Material.

• 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.
