A. Install the Outside Air Kit

tionisprovidedtoallowproperdrafttothereplacesystem.
See Section 2.
Using an outside air kit must be used for combustion to mini-
mize the effects of negative pressure within the structure.
We recommend you utilize the shortest duct run to optimize
the performance of the outside air kit. The outside air kit inlet
should be positioned in a manner that will not allow snow,
leaves, etc. to block the inlet. In some installations the air
duct may need to be run vertically. In such an installation, a
3 ft (914 mm) height difference must be maintained from the
top of the uppermost chimney section to the outside com-
bustion air inlet. See Figure 16.1 on page 16.
See Figure 17.1 on page 17 for proper placement of outside
air inlet.
The outside air kit is installed on the right hand side of the
replace.SeeFigure15.1forhandlelocation/operation.

Installation of Fireplace
Figure 15.1 Outside Air Installation
1.
Cut a 6 in. (152 mm) hole in outside wall to accommodate
air piping. The outside air is located on top, auxiliary
convection air intake is located on the bottom. See Figure
15.1.

todirectlyconnectoutsideairtoreplaceintake.Insulate
the pipe to prevent frost condensation.
3. Use the supplied termination caps.
4. Seal between the wall and the pipe with silicone to prevent
moisture penetration and air leaks.
5. Seal between the termination cap and the house with
siliconetopreventairinltration.
NOTE: A control knob allows you control of the outside air
inlet. Use of outside air for combustion is required to
conserve heated air within the structure and to provide
makeupairtokeepthereplaceventingproperly.
IMPORTANT!
TURN CLOCKWISE TO “OPEN” POSITION.
OUTSIDE AIR KNOB MUST BE IN THE “OPEN” POSI-
TION TO OPERATE FIREPLACE PROPERLY.
