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.

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.
Noncombustible | Requirements for |
Material Distance (A) | Safe Installation |
|
|
12" or more | Noncombustible material OK. |
Between 8" and 12" | 24" or 30" Models: Install |
| fireplace hood accessory |
| (GA6050, GA6052, or |
| GA6053 see Accessories, |
| page 34). |
Less than 8" | Noncombustible material |
| must be extended to at least |
| 8". See Between 8" and 12", |

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 11.
