If Using Mantel
You must have noncombustible material(s) such as slate, marble, tile,
etc. At least ½ in. 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
inches. you must install the fireplace hood accessory. Even if
noncombustible material is more than 12 inches, you may need the
hood accessory to deflect heat away from mantel shelf. See Figure 6, 7
and 8.
Mantel Clearances
In addition to meeting noncombustible material clearances, you must
also meet required clearances between fireplace opening and mantel
shelf. If the clearances listed below are not met, you will need a hood.
Determining Mantel Clearances
If you meet minimum clearances requirements between mantel shelf
and top of fire place opening, a hood is not necessary. See
Figure 6
Determining Minimum Mantel Clearances When Using a
Hood
If minimum clearance is Figure 7 are not met, you must have
a hood. When using a hood there are still certain minimum
clearances required. Follow minimum clearances shown in
Figure 7 when using a hood.
The gas log heater must be installed at least 1 3/8” above
any combustible flooring material, such as carpeting or tile,
which is closer than 14” to the base of the fireplace. The minimum
distance must be maintained from the top surface of carpeting, tile,
etc. See Figure 8.
OR
The gas log heater may be installed nearer to the floor is a
minimum of 14” of noncombustible material such as a slate or
marble is installed between the base of the fire place and the
combustible flooring. See Figure 9.
When installing your log set as a vent free installation the damper
clamp can be used to eliminate the potential for odors when
burning the logs for the first time.
IMPORTANT: If these minimum clearances are not met, you
must operate heater with chimney flue damper open. Go to
“Installing Damper Clamp”, page 13.
