Carefully follow the instructions below. This will ensure safe installation into a masonry,
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 2.
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 2).
Note: When installing your gas logs into a manufactured firebox, follow firebox manufacturer’s instructions for mini- mum clearances to combustible materials.
B.Clearances from the top of the fireplace opening to the ceil- ing should not be less than 42".

12" or more | Noncombustible material OK. |
|
|
Between 8" and 12" | Install fireplace hood accessory |
| (GA6050 or GA6053 see Accessories, |
| page 21). |
|
|
Less than 8" | Noncombustible material must be ex- |
| tended to at least 8". See Between 8" |
| and 12", above. If you cannot extend |
| material, you must operate appliance |
| with flue damper open. |

Minimum Noncombustible Material Clearances
If Not Using Mantel
Note: If using a mantel proceed to If Using Mantel. If not using a mantel, follow these instructions.
You must have noncombustible material(s) above the fireplace opening. Noncombustible materials (such as slate, marble, tile, etc.) must be at least 1/2" thick. With sheet metal, you must have noncombustible material behind it. Noncombustible material must extend at least 8" up (for all models). If noncom- bustible material is less than 12", you must install the fireplace hood accessory (24" and 30" Models Only). See Figure 3 for minimum clearances.
Figure 3 - Heat Resistant Material (Slate, Marble, Tile,
etc.) Above Fireplace
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" 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. Even if noncombustible material is more than 12", you may need the hood accessory to deflect heat away from your mantel shelf. See Figure 3 and Figures 4 and 5, page 6, for minimum clearances.
IMPORTANT: If you cannot meet these minimum clearances, you must operate appliance with chimney flue damper open. Go to Installing Damper Clamp Accessory for Vented Operation , page 7.
Mantel Clearances
In addition to meeting noncombustible material clearances, you must also meet required clearances between fireplace opening and mantel shelf. If you do not meet the clearances listed below, you will need a hood.
Determining Minimum Mantel Clearance
If you meet minimum clearance between mantel shelf and top of fireplace opening, a hood is not required (see Figure 4, page 6).
