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

Minimum Clearances For Side Combustible Material, Side Wall and

Ceiling

A. Clearances from the side of the fireplace cabinet to any combustible 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 combus- tible material must be 4" from the side of the fireplace opening (see Figure 4).

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

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

*Minimum 16 inches from Side Wall

Figure 4 - Minimum Clearance for

Combustible to Wall

NOTICE: Manual control heaters maybeusedasaventedproduct. If so, you must always run heater with chimney flue damper open. If running heater with damper open, noncombustible material above fireplace opening is not needed. Go to Installing Damper Clamp Accessory for Vented Operation, page 11.

Minimum Noncombustible Material Clearances

If Not Using Mantel

Note: If using a mantel, proceed to If Using Mantel, page 10. If not using a mantel, follow the information below.

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. Noncombus- tible material must extend at least 8" up (for all models). If noncombustible material is less than 12", you must install the fireplace hood accessory (24" and 30" models only). See Figure 5, page 10 for minimum clearances.

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