CAUTION: 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 RE-

MOVED FROM INSIDE THE FIREPLACE. DO NOT REMOVE THE KNOCKOUT UNLESS YOU ARE INSTALLING A GAS LINE. If removal is attempted from the outer wrapper, 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.

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 must connect to a gas shut-off valve usually recessed flush into the wall or floor. The valve should be controlled by a removable valve key for safety.

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: REPACK INSULATION MATERIAL IN SQUARE HOLE AROUND GAS LINE, INTERIOR AND EXTERIOR, TO SEAL.

In Canada, this provision is intended for connection to a decorative gas appliance only in accordance with the latest National Gas Installation Code, CAN 1-B149.1. This complies with the ULC S610 standard.

CAUTION: WHEN USING THE DECORATIVE GAS APPLIANCE, THE FIREPLACE DAMPER MUST BE SET IN THE FULLY OPEN POSITION.

COLD CLIMATE INSULATION

If you live in a cold climate, it is especially important to seal all cracks around the fireplace 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 chimney sections.

Note: 2" (51 mm) air space must be preserved for all 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 Trim

It is sometimes best to frame your fireplace after it is positioned and the chimney is in- stalled. Frame enclosure for chimney and fireplace with 2 x 4’s (or heavier) lumber.

Note: The header may rest on the two (2) metal top spacers on top of the unit but the header must not be notched to fit around the spacers.

In Canada, the minimum height for a combustible mantel is 18" (457 mm) above the opening. Figure 54 shows typical Canadian installation. In installations other than Canada, combustible mantels and trim may be installed 12" (305mm) above the opening as per NFPA 211, Section 7-

3.3.3.and Figure 55. If a mantel is of a non- combustible material, it is exempt from the requirements as long as it does not interfere with the operation of glass doors.

Hearth Extensions and Wall Shields

A hearth extension must be installed with all fireplaces. Its purpose is twofold. It protects a combustible floor in front of the fireplace from both radiant heat and sparks and it distinguishes the prescribed hearth extension area from other non-protected surfaces.

The hearth extension must extend beyond the front and both sides of the CPF-38 and CST-38 fireplace side openings. A hearth extension on the end opening of the CPF-38 fireplace is optional. Use a hearth extension constructed of a durable noncombustible material having an equal or greater insulating value of k=.84 BTU IN/FT2 HR ° F or a thermal resistance that equals or exceeds r=1.19 HR ° F FT2/BTU IN. A minimum ³⁄₈" (10 mm) thick noncombustible material is all that is required over a noncom- bustible or slab floor.
