Superior BCD36MH, BC36MH Combustion Air Kits, Gas Line Connection, Cold Climate Insulation

Always check local building codes. Instal- lation of the BFK36 Blower Kit must comply with local regulations as well as the National Electric Code.

Combustion Air Kits

These appliances are equipped with an outside (make-up) air door and integral actuator arm and an outside air kit with a collar, duct and hood (90L83). The appliance must be installed with an outside air vent system (Figure 38). These kits come complete with detailed installation instructions and all components necessary in completing a combustion air vent system.

After completing the installation of the com- bustion air vent system the actuator arm must be put in service and tested to ensure proper operation before completing any enclosure around the firebox. Failure to do so may result in extensive and costly rework.

Locate the actuator arm along the right side of the appliance firebox opening and refer to Figure 39. To operate, push the end of the actuator to the left as shown in Figure 39, until it "pops" free of its "locked" position. Pull the actuator forward to open the combustion air door, and push it back to close. To "lock" the combustion air door closed, ensure the actuator is pushed all the way back then push the end of the actuators to the right until the step in the actuator moves behind the appliance front face within the slotted opening.

Operate the actuator through several cycles including the "lock position. Ensuring proper operation and freedom of movement. Return the actuator arm to the locked position.

Gas Line Connection

Install a 1/2” 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 shut-off valve recessed flush into the wall or floor. The valve should be con- trolled by a removable valve key for safety.

Always plumb gas line installation per local codes. Check all connections using a gas leak test solution (also referred to as bubble leak solution). Note: Using a soapy water solution (50% dish soap, 50% water) is an effective leak test solution but it is not recommended, because the soap residue that is left on the pipes/fittings can result in corrosion over time. Never test any gas line connection with a match or open flame.

This provision is intended for connection to a decorative gas appliance incorporating an automatic shut-off device and complying with the Standard for Decorative Gas Appliances for installation in vented fireplaces, ANSI Z21.60 (1991) or American Gas Association draft re- quirements for Gas-Fired Log Lighters for Wood Burning Fireplaces, Draft No. 4 dated August, 1993. Install in accordance with the National Fuel Gas Code, ANSI Z223.1. This complies with the revised U.L. 127 standard.

WARNING

This fireplace has not been tested with an unvented gas log set. To reduce risk of fire or injury, do not install an unvented gas log set into this fireplace.

NOTE: DIAGRAMS & ILLUSTRATIONS ARE NOT TO SCALE.

CAUTION

When using the decorative gas appliance, the fireplace damper must be set in the fully open position.

CAUTION

Plumbing connections should only be performed by a quali- fied, 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 the indentation located at the bottom and slightly off center in the side refractories. THE KNOCK-

OUT 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 wrap- per, side refractory damage may occur. With a medium-sized hammer, lightly tap the surface of the indentation. The refractory material is very thin in this area and is easily removed. Once a small hole has been made, continue tapping until you have reached sufficient diameter for the gas line to fit through. The entire knockout does not have to be removed. Remove insulation in the gas line channel.

IMPORTANT

Repack insulation material in square hole around gas line, interior and exterior of fireplace, to seal.

COLD CLIMATE INSULATION

If you live in a cold climate, it is especially important to seal all cracks around the fire- place and wherever cold air could enter the room with noncombustible material. Surround material 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 directly against the chim- ney sections.

Note: 1" (25 mm) air space must be preserved for all materials extending for any continuous length adjacent to the chimney.
