ASSEMBLY STEPS

Note: The following steps represent the normal sequence of installation. Each installation is unique, however, and might require a different sequence.

1.Position firebox prior to framing or into prepared framing.

2.Install the chimney system.

3.Connect house wiring to the fireplace for later attachment of optional blower.

4.Install optional outside combustion air kit.

5.Plumb gas line if a decorative gas appliance will be used. (Gas connections should only be performed by an experienced, licensed/certi- fied tradesman.)

6.Complete the installation, finish wall mate- rial, surround and hearth extension to your individual taste.

7.Assemble and attach optional glass door assembly.

Study the three dimensional illustration (Fig- ure 1 ) to get a general idea of each element of your fireplace system.

PRE-INSTALLATION NOTES

The fireplace may be installed directly on a combustible floor or raised on a platform of an appropriate height. Do not place fireplace on carpeting, vinyl or other soft floor coverings. It may, however, be placed on flat wood, ply- wood, particle board or other hard surfaces. Be sure fireplace rests on a solid continuous floor or platform with appropriate framing for support and so that no cold air can enter the room from under the fireplace.

The fireplace may be positioned and then the framing built around it, or the framing may be constructed and the fireplace positioned into the opening.

Usually, no special floor support is needed for the fireplace, however, to be certain:

1.Estimate the total weight of the fireplace system including chimney and surround ma- terials such as brick, stone, etc., to be in- stalled. Shipping weights for the fireplace may be found on page 18.

2.Measure the square footage of the floor space to be occupied by the system, surrounds and hearth extensions.

3.Note the floor construction, i.e. 2 x 6’s, 2 x 8’s or 2 x 10’s, single or double joists, type and thickness of floor boards.

4.Use this information and consult your local building code to determine if you need addi- tional support.

CAUTION: DO NOT BLOCK THE HEAT-CIRCU- LATING AIR INLET AND OUTLET PORTS ON CIRCULATING MODELS. DOING SO MAY RE- SULT IN A POTENTIAL FIRE HAZARD.

If you plan to raise the fireplace and hearth extension, build the platform assembly then position fireplace and hearth extension on top. Secure the platform to the floor to prevent possible shifting.

CLEARANCES

Minimum clearance to combustibles for the appliance is as follows: sides and back - 1" (25 mm), floor - 0" (0 mm), adjacent wall - 12" (305 mm), ceiling - 37-1/2" (953 mm).

INSTALLING THE FIREPLACE

Step 1. Slide the fireplace into prepared fram- ing or position fireplace in its final position and frame later.

The fireplace may not be recessed into a com- bustible floor. Maintain the floor to hearth clear- ance established by the fireplace lower front face.

Step 2. Insert the provided metal safety strips, beneath the fireplace as illustrated (Figures 6, 7 and 8 ). The safety strips should overlap 1/2" for continual coverage of the floor.

Note: Safety strips are not required when fire- place rests on a noncombustible surface.

Note: Install the hearth extension only as illus- trated.

The safety strips should extend from front of the fireplace at least 1-1/2" and should extend to be at least flush with the sides. In the event a wooden support is used to elevate the fireplace above the floor, a “Z” type safety strip should be fabricated and used to protect the front surface of the wood support as well as the floor beneath the hearth extension (Figures 8 and 9 ). The safety strips should be tacked down to prevent possible movement.

Note: The “Z” type safety strip is not supplied.
