Outside Air Kit Installation (provided)
These appliances are equipped with a combustion air inlet collar so that it is possible to duct combustion air from the outdoors to the firebox. To accomplish an outside air hook- up, use only the Outside Air Kit provided with these appliances. These kits come complete with all components necessary in completing a combustion air vent system.
Indoor Installations - An Air Gate Kit must be installed prior to the installation of the Outside Air Kit (purchased separately - see Page 23 for ordering information).
Outdoor Installations - Units installed outdoors are required to have the Outside Air Kit (pro- vided) installed without the Air Gate Kit. The optional Air Gate Kit is not approved on outdoor installations.

Install as follows:
Connect the 4" (102 mm) Class 0 air duct provided, to the collar on the fireplace with the clamps provided in the kit’s hardware package
(Figure 16).
Route the Class 0 metallic air duct out the back wall or side wall, up through the ceiling or floor joists to an outside wall. The air duct’s inlet should be located above any anticipated snow level. Check local building codes for any restrictions. We recommend that the inlet be at least 4 feet above grade level.
Note: Air inlet ducts must not terminate in attic space.
CAUTION
Avoid installing the air inlet where the opening could be blocked by snow, bushes or other obstacles. The maximum height for the outside air is 50 feet above the hearth, providing the air inlet is terminated a minimum of three (3) feet below the chimney cap level.
ATTENTION
Évitez d’installer la prise d’air ou l’ouverture pourrait etre bloquee par la neige, les buissons ou d’autres obstacles. La hauteur maximum pour la prise d’air est de 50 pi. Au dessus de la base du foyer à condition qu’elle se situe
àau moins 3 pi. En dessous de la sortie de la cheminée.
NOTE: DIAGRAMS & ILLUSTRATIONS ARE NOT TO SCALE.
Note: Secure the duct hood to a vertical post with the inlet positioned downward. Ensure that nothing blocks the hood opening. This duct must never terminate higher than 3 feet below the fireplace termination (Figure 17).

Duct Hole Framing:
Cut or frame a hole through the outside of the enclosure for the installation of the duct inlet hood. A 5" (127 mm) diameter hole is required. Feed the loose end of the flexible duct through the hole cut for the inlet hood and attach to the collar on the inlet hood using two (2) screws. Insert the hood into the opening. Secure in place with nails driven through the holes in hood flange. Seal with noncombustible waterproof silicon type caulking. If additional duct is needed, use Class 0 metallic air duct (refer to Figure 16).
