ATTENTION

Certaines portes de verre recou- vrent le revêtement noir en métal du foyer. SI la façade du foyer a étérecouverteavecdesmatériaux non-combustibles, il se pourrait qu’il n’y ait pas suffisament de dégagement pour installer les portes de verre de votre choix. Assurez d’avoir un dégagmet suf- fisant à tout moment afin de ne pasinterféreravecl’installationet l’opération des portes de verre.

In Canada, the minimum height for a combustible mantel is 18" (457 mm) above the fireplace opening. Figure 51 shows typical Canadian installations. Combustible mantels and trim may be installed 12" above the fireplace opening as per NFPA 211-latest edition. and Figure 52. If a mantel is of a noncombustible material, it is exempt from these requirements as long as it does not interfere with the installation or operation of glass doors.

*Note: 2" clearance to combustibles required in Canada.

Note: Do not place any combustible materials on the fireplace face.

WARNING

Only non-combustible materials are allowed on front face (front fireplace frame) and around the perimeter within 5" minimum on top and 1/2" on sides.

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 on top of fireplace or against chimney sections. If gas logs are installed, the gas line holes and other openings should be caulked with high temperature caulk or stuffed with unfaced fiberglass insulation.

Note: A 1"* air space must be preserved for insulation and construction 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 FINISHES

Mantels and Trim

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

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

These fireplaces may sit directly on a combustible surface. A 1"* air space is required between insulation and construction material and the chimney. A 1" air space is required between combustible framing and fireplace outer wrapper.

Hearth Extensions and Wall Shields

A hearth extension must be installed with all fireplaces. It is to protect the combustible floor in front of the fireplace from both radiant heat and sparks. The hearth extension must extend 8" beyond both sides of the fireplace opening and 16" beyond the front (see Figure 53). Use a hearth extension constructed of a durable noncombustible material having an equal or better (lower k value) 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. With these values, determine the minimum thickness/material required using the formula and Table 5 on Page 21.

Note: Any noncombustible material having a thickness of 1" whose k value is less than

.84 or whose r value is more than 1.19 is ac- ceptable.

If the fireplace is installed on a combustible floor, use the metal safety strips (provided) on the floor extending half under the fireplace and half under the hearth extension (refer to Figures 21 & 22).

A wall shield is required where a continuous perpendicular side wall is within 12" of the fireplace opening (Figure 53). Use a 24" W x 30" H x 1/2" wall shield constructed of a durable, noncombustible material having an equal or better (lower k value) insulating value than k = .54 BTU IN/FT2 HR °F. At no time may a perpendicular side wall be located closer than 7" from the fireplace opening.

If fireplace is installed diagonally across a 90° corner; no wall shields are required.
