COMBUSTION AIR ASSEMBLY
TO INSTALL THE OUTSIDE COMBUSTION AIR KIT
1.Remove the cover plate from the outside air opening located on the left OR right side of the fireplace. DO NOT remove the cover plate if the outside air will not be connected.
2.Insert the outside air starting collar into the hole on the side of the fireplace chosen by step 1 above. Fasten the collar in place with the four sheet metal screws provided. See Figure 24.
3.For residential type installation, cut a
4.Select and cut a piece of duct a sufficient length to attach to the starting collar on the fireplace and protrude at least three inches beyond the face of the wall to which the inlet air vent (the termination cap) will be attached. For maximum efficiency and safety, use FP4U Air Duct in residential installations; use FP6U Air Duct in manufactured home installations. Ducts may be cut with a standard pocket knife. Do not use a combustible duct. Always use UL Listed Class 0 or 1 duct material. (NOTE: If it is necessary to splice the duct, model 403 Duct Connector should be used to splice the FP4U duct sections, and model 603 Duct Connector should be used to splice the FP6U duct sections. See Figure 26.)
5.Slip one end of the duct onto the starting collar on the fireplace. Use the duct clamps or duct ties provided to secure the duct end to the collar attached to the fireplace. See Figure 24. (NOTE: If the duct is the insulated type, temporarily push the insulation back from the end of the duct approximately two inches before securing the end of the duct onto the starting collar.)
6.Route the air duct through the hole cut in the wall and use the duct clamps or ducts ties provided to secure it to the termination cap as shown by Figure 25.
7.Mount the Termination Cap with “TOP” upward to prevent cold air from entering through the wall. Nail or screw the Termination Cap to the surface of the wall. (If the wall covering is brick or stone, use appropriate masonry fasteners to secure the Termination Cap to the wall.)
When the fireplace is in use, the fireplace’s “outside combustion air” damper connected to an outside air assembly may be opened to allow air from outside to enter the fireplace firebox. When the fireplace is not in use, the “outside combustion air” damper should be closed to prevent cold air from entering the firebox. An “outside combustion air” damper is open when its control lever is up, and closed when its control lever is down. A control lever for each “outside combustion air” damper is located inside the firebox near the top of the side firebrick on each side of the fireplace.
GAS APPLIANCE INSTALLATION
WARNING: Improper installation or operation of a gas appliance in this fireplace can allow unburned gas to leak out which will cause a fire or explosion hazard, or the release of poisonous carbon monoxide into the dwelling which can cause serious injury or death to its inhabitants. To reduce these risks to a minimum, the following important notices and instructions should be read and followed carefully.
IMPORTANT NOTICES:
1.The provision for a gas line is intended for connection to a decorative gas appliance which has an automatic shutoff device and complies with the Standard for Decorative Gas Appliances for Installation in Vented
