Minimum Noncombustible Material Clearances
If Not Using Mantel
Note: If using a mantel, proceed to If Using Mantel. If not using a mantel, follow the information below.
You must have noncombustible material(s) above both fireplace openings. 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. See Figure 5 at right 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 9.
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 (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 5 and 6 and Figure 7, page 9, for minimum clearances.

12" or more | Noncombustible material OK. |
Between 8" and 12" | Install fireplace hood accessory |
MANTEL CLEARANCES
In addition to meeting noncombustible material clearances, you must also meet required clearances between fireplace openings and mantel shelf on each side of the fireplace. 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 6).
Determining Minimum Mantel Clearance When using a Hood
If minimum clearances in Figure 6 are not met, you must have a hood. When using a hood there are still certain minimum mantel clearances required. Follow minimum clearances shown in Figure 7, page 9 when using hood.
NOTICE: Surface temperatures of adjacent walls and mantels become hot during operation. Walls and mantels above the firebox may become hot to the touch. If installed properly, these temperatures meet the requirement of the national product standard. Follow all minimum clearances shown in this manual.
NOTICE: If your installation does not meet the mini- mum clearances shown, you must do one of the following:
•operate the logs only with the flue damper open
•raise the mantel to an acceptable height
•remove the mantel
| (GA6050, GA6052 or GA6053, see |
| Accessories, page 27). |
Less than 8" | Noncombustible material must be |
| extended to at least 8". See Between |
| 8" and 12", above. If you cannot |
| extend material, you must operate |
| heater with flue damper open. |
