Minimum Clearances For Side Combustible Mate- rial, 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 5.

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 opening (see Figure 5).

Note: When installing your gas logs into a manufactured fire- box, 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

Figure 5 - Minimum Clearance for Combustible to Wall

NOTICE: Manual control heaters may be used as a vented product. If so, you must always run heater with chimney flue damper open. If running heater with damper open, noncombustible material above fire- place opening is not needed. Go to Installing Damper Clamp Accessory for Vented Operation, page 10.

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" up (for all models). If noncombustible material is less than 12", you must install the fireplace hood accessory (24" and 30" models only). Even if noncombustible material is more than 12", you may need the hood accessory to deflect heat away from your mantel shelf. See Figure 6 and Figures 7 and 8 on page 9 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 10.

Noncombustible	Requirements for
Material Distance (A)	Safe Installation

12" or more	Noncombustible material okay.
Between 8" and 12"	24" or 30" Models: Install
	fireplace hood accessory
	(GA6050, GA6052, or
