INSTALLATION

Continued

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 cabi- net to any combustible material and wall should follow diagram in Figure 8.

Example: The face of a mantel, bookshelf, etc. is made of combustible material and pro- trudes 3 1/2" from the wall. This combustible material must be 4" from the side of the fire- place cabinet (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.

Example

*Minimum 16 inches from Side Wall

Combustible to Wall

NOTICE: Manual control heaters may be used as a vented prod- uct. If so, you must always run heater with chimney flue damper open. If running heater with damper open, noncombustible material above fireplace open- ing is not needed. Go to Install- ing Damper Clamp Accessory for Vented Operation, page 12.

Minimum Noncombustible Material Clearances

If Not Using Mantel

Note: If using a mantel, proceed to If Using Man- tel, page 10. If not using a mantel, follow the in- formation 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 noncombus- tible material behind it. Noncombustible material must extend at least 8" up (for all models). If non- combustible material is less than 12", you must in- stall the fireplace hood accessory (24" model only). See Figure 5 for minimum clearances.

IMPORTANT: If you cannot meet these minimum clearances, you must operate heater with chim- ney flue damper open. Go to Installing Damper Clamp Accessory for Vented Operation, page 12.
