A. Design and Installation Considerations
Consideration must be given to:
• Safety
• Convenience
• Trafc ow
• Chimney and chimney connector required
It is a good idea to plan your installation on paper, using exact
measurements for clearances and oor protection, before
actually beginning the installation. If you are not using an
existing chimney, place the appliance where there will be a
clear passage for a factory-built listed chimney through the
ceiling and roof.
We recommend that a qualied building inspector and your
insurance company representative review your plans before
and after installation.
If this appliance is in an area where children may be near it is
recommended that you purchase a decorative barrier to go
in front of the appliance. Remember to always keep children
away while it is operating and do not let anyone operate
this appliance unless they are familiar with these operating
instructions.

A. Locating Your Appliance & Chimney
Location of the appliance and chimney will affect perfor-
mance. As shown in Figure 10.1 the chimney should:
• Install through the warm space enclosed by the build-
ing envelope. This helps to produce more draft, espe-
cially during lighting and die down of the re.
• Penetrate the highest part of the roof. This minimizes
the affects of wind turbulence and down drafts.
• Consider the appliance location in order to avoid oor
and ceiling attic joists and rafters.
• Locate termination cap away from trees, adjacent
structures, uneven roof lines and other obstructions.
Your local dealer is the expert in your geographic area and
can usually make suggestions or discover solutions that will
easily correct your ue problem.

A. Outside Air Kit Installation
A source of air (oxygen) is necessary in order for combus-
tion to take place. Whatever combustion air is consumed
by the 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 needed.
An optional Outside Air Kit is avail able.
Optional OAK-ACC includes: Termination cap, (2) wire ties,
ex adapter, and fasteners
Items Needed for Installation (not supplied)
• 4 inch ex aluminum pipe, or if using alternate material,
then it shall be made from durable, non-combustible,
heat resistant material up to 350oF. Cut the pipe to the
required length for your installation.
• Phillips head screw driver
• Silicone sealant
• Drills and saws necessary for cutting holes through the
wall or ooring in your home.
Installation Instructions
1. Remove all materials from packing box.
2. Floor & Rear Installation: Cut a 4 inch (102mm) hole in
outside wall or oor to accommodate outside air piping.
Use 4 inch (102mm) aluminum metal 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 oor) and the pipe with silicone to
prevent moisture penetration.
WARNING
Fire Risk. Asphyxiation Risk.
Do not draw outside combustion air from:
• Wall, oor or ceiling cavity
• Enclosed space such as an attic or garage
• Close proximity to exhaust vents or chimneys
Fumes or odor may result
