Outside combustion air ducting may be run upwards or vertically through framing and ceiling joists, with the hood installed through an outside wall and 3' (914 mm) below the termi- nation. Ducting may also be run downward through floor joists and under the home to a ventilated crawlspace not considered part of the living area of the home.
Note: Do not terminate combustion air kit in attic space under any circumstances.
An optional termination shroud is available to partially conceal the
If glass doors are to be installed on these fireplaces, refer to specific installation instructions packed with the glass doors. Use only the doors that are listed for use with these fire- places. Use of other
CAUTION: CERTAIN GLASS DOORS OVERLAP THE BLACK METAL FACING OF THE FIRE- PLACE. IF THE FIREPLACE HAS BEEN FACED WITH NONCOMBUSTIBLE MATERIALS, THERE MIGHT NOT BE SUFFICIENT CLEARANCE TO INSTALL THE GLASS DOORS OF YOUR CHOICE. ENSURE ADEQUATE CLEARANCE IS MAINTAINED AT ALL TIMES SO AS NOT TO INTERFERE WITH THE INSTALLATION AND OPERATION OF GLASS DOORS.
GAS LINE CONNECTIONCAUTION: PLUMBING CONNECTIONS SHOULD ONLY BE PERFORMED BY A QUALIFIED, LICENSED PLUMBER. MAIN GAS SUPPLY MUST BE OFF WHEN PLUMBING GAS LINE TO FIREPLACE OR PERFORMING SERVICE.
If you’re installing a gas line, connect it before the fireplace is framed and enclosed in the finished wall. The gas knockout is determined by a 1 ¹⁄₈" (29 mm) round indentation located at the bottom and slightly off center in the side refractories.
THE KNOCKOUT IS ALWAYS REMOVED FROM INSIDE THE FIREPLACE. DO NOT REMOVE THE KNOCKOUT UNLESS YOU ARE INSTALLING A GAS LINE. If removal is attempted from the outer wrapper,
Install a ¹⁄₂" (13 mm) gas supply line through fireplace wall for connection to a decorative gas appliance inside the firebox. Outside, the gas supply line connects to a gas
Always plumb gas line installation per local codes. Check all connections with soap suds; leaks will bubble. Never test any gas line connection with a match or open flame.
IMPORTANT:
This provision is intended only for connection to a decorative gas appliance incorporating an automatic
CAUTION: WHEN USING THE DECORATIVE GAS APPLIANCE, THE FIREPLACE DAMPER MUST BE SET IN THE FULLY OPEN POSITION.
Vent Free AppliancesThese units have been tested and approved to ANSI/IAS/AGA Z21.11.2 for use with unvented gas appliances and complies with the standard for
The unit has been tested for use with any unvented gas log sets having a maximum rating of 40,000 BTU. The minimum mantle configurations are outlined in Figures 45 and 46.
These fireplaces have been marked with a maximum rating of 40,000 BTU to assure that homeowners do not exceed the allowable limits for all allowed installations of mantles.
NEVER INSTALL AN UNVENTED GAS LOG SET WITH A BTU GREATER THAN 40,000.
NOTE: DIAGRAMS & ILLUSTRATIONS NOT TO SCALE.
If you live in a cold climate, it is especially important to seal all cracks around the fireplace opening with noncombustible material and wherever cold air could enter the room. Surrounding materials must be caulked where it meets the black metal facing of the fireplace to avoid cold air intrusion. Use noncombustible caulking material only on fireplace facing to seal. Also, the outside air inlet duct should be wrapped with noncombustible insulation to minimize the formation of condensation. Do not place insulation materials against chimney sec- tions.
Note: A 2" (51 mm) air space must be preserved for all combustible materials extending for any continuous length adjacent to the chimney.
It is especially important to insulate between the studs of an outside chase cavity and under the floor if the floor is above ground level. Do not place insulation directly against the fireplace or chimney system
FIREPLACE FINISHESMantels and TrimIn Canada, the minimum height for a combustible mantel is 24" (610 mm) above the fireplace opening. Figure 45 shows typical Cana- dian installation. In installations other than Canada, combustible mantels and trim may be installed 12" (305 mm) above the fireplace opening as per NFPA 211; Section
