INSTALLATION

Continued

Carefully follow the instructions below. This will ensure safe installation into a masonry, UL127-listed manufactured fireplace, or listed vent-free firebox.

Minimum Clearances For Side Combustible Material, Side Wall, and Ceiling

A.Clearances from the side of the fireplace cabinet to any com- bustible material and wall should follow diagram in Figure 4.

Example: The face of a mantel, bookshelf, etc. is made of combustible material and protrudes 3 1/2" from the wall. This combustible material must be 4" from the side of the fireplace cabinet (see Figure 4).

Note: When installing your gas logs into a manufactured firebox, follow firebox manufacturer’s instructions for minimum clear- ances to combustible materials.

B.Clearances from the top of the fireplace opening to the ceiling should not be less than 42 inches.

Example

*

*Minimum 16 inches from Side Wall

Figure 4 - Minimum Clearance for Combustible to Wall

If Using Mantel

You must have noncombustible material(s) above the fireplace opening. Noncombustible materials (such as slate, marble, tile, etc.) must be at least 1/2 inch thick. With sheet metal, you must have noncombustible material behind it. Noncombustible material must extend at least 8 inches up. If noncombustible material is less than 12", you must install the fireplace hood accessory. Even if noncom- bustible material is more than 12", you may need the hood accessory to deflect heat away from your mantel shelf. See Figure 5 and Figures 6 and 7, page 10, for minimum clearances.

IMPORTANT: If you cannot meet these minimum clearances, you must operate heater with chimney flue damper open. Go to Install- ing Damper Clamp Accessory for Vented Operation, page 11.
