DO NOT permanently place furniture or other items such as decorative pillows within 60" of the fireplace front face.

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.Install optional outside combustion air kit.

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

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

6.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 LA41 fireplace is as follows; sides and back – 2" (51mm), combustible floor – 0" (0mm), adjacent wall 20" (508mm), adjacent shielded wall (K factor of .54 or less 24" W x 36" H ) 14" (356mm), ceiling – 37 ¹⁄₂" (953mm).

Note: Clearance at the nailing flange for both fireplace models is 0" (0mm).

Note: Adjacent wall considerations are for an adjacent wall on only a single side. Walls should not be placed at minimum distance at both sides of the fireplace.

NOTE: DIAGRAMS & ILLUSTRATIONS NOT TO SCALE.

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 clearance established by the fireplace lower front face.
