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 in., you
must install the fireplace hood accessory. Even if noncombustible material is
more than 12 in., you may need the hood accessory to deflect heat away from mantel shelf.
See Fig. 4, 5 and 6 for minimum clearances requirements.
IMPORTANT: If these minimum clearances are not met, you must operate heater with
chimney flue damper open. Go to “Installing Damper Clamp Accessory for Vented
Operation,” page 15.
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 clearance requirements between mantel shelf and top of fireplace
opening, a hood is not necessary (see Fig. 5).
Noncombustible
Material Distance Requirements for Safe Installation
8 in. or more Noncombustible material okay.
Less than 8 in.
Noncombustible material must be extended to at least 8 in. See be-
tween 8 in. and 12 in. above. If you can not extend material, you must
operate heater with flue damper open.
Determining Minimum Mantel Clearance
When Using a Hood
If minimum clearances in Fig. 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
