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 fi re
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, fl ex adapter,
and fasteners
Items Needed for Installation (not supplied)
• 4 inch fl ex aluminum pipe, or if using alternate material,
then it shall be made from durable, non-combustible, heat
resistant material up to 350
required length for your installation.
• Phillips head screw driver
• Silicone sealant
• Non-combustible pedestal sealing material if installing with
the Alternate Floor confi guration.
• Drills and saws necessary for cutting holes through the wall
or fl ooring 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 fl ex adapter to
the appliance using 4 screws. Secure with Wire Tie. Figure
39.1.
3. Floor: For standard fl oor installation remove the circular
"knock-out" in the base of the pedestal.
4. Floor & Rear Installation: Cut a 4 inch (102mm) hole in out-
side wall or fl oor to accommodate outside air piping. Use 4 inch
(102mm) aluminum metal fl ex 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 fl oor) and
the pipe with silicone to prevent moisture penetration.
For Floor Installa-
tions Remove
Circular "Knock-Out"
in Base of Pedestal.

5. Floor Installation Alternative: In some instances
you may not be able to install the fl ex pipe as show in
Figure 39.1.
If that is the case, follow the instructions for a rear
installation install the fl ex pipe to the rear of the ped-
estal and remove the circular "Knock-Out" in the base
of the 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 infi ltration.
Figure 39.2.
Sealing Material

WARNING! Risk of Fire and Asphyxiation!
Do not draw outside combustion air from:
• Wall, fl oor, ceiling cavity or enclosed space such
as an attic or garage. Also do not draw outside air
from close proximity to exhaust vents or chimneys.
Fumes or odor may result if you do.
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
fl ue.
• The fi re will not burn properly and their will be
smoke spillage when the door is opened due to air
starvation.
