TYPICAL INSTALLATION SEQUENCE

The typical sequence of installation follows, however, each installation is unique resulting in variations to those described.

1. Construct the appliance framing.

2. Route gas supply line to appliance location.

3. Position the appliance.

4. Install the vent system and exterior termination.

5. Field wire and install operating control switch.

6. Make connection to gas supply.

7. Install (optional) outside Air Kit.

8. Install the logs and rockwool.

9. Checkout appliance operation.

10. Adjust burner to ensure proper flame

appearance.

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, plywood, 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 and surround materials such as brick, stone, etc., to be installed.

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 additional support.

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.

INSTALLING THE FIREPLACE

Step 1. Frame appliance enclosure as illus-

trated in

Figures 4 through 7

Note: The nailing flanges, combustible framing members and screw heads located in areas directly adjacent to the nailing flanges, are EXEMPT from the

¹⁄₂

tible requirements for the firebox wrapper. Combustible framing may be in direct contact with the nailing flanges and may be located closer than

¹⁄₂

" from screw heads and the firebox wrapper in areas adjacent to the nailing flanges. Frame the opening to the exact dimensions specified in the framing details of this manual.

Note: The framed depth, 21 a framed wall, must always be measured from a finished surface. If a wall covering such as drywall is to be attached to the rear wall, then the 21

⁵⁄₈

" (549 mm) must be measured from the drywall surface. It is important that this dimension be exact.

If the appliance is to be elevated above floor level, a solid continuous platform must be constructed.

The header may rest on the top metal spacers, but must not be notched to fit around them.

Consult all local codes.
