MANTEL CLEARANCES (Figure 4)
Minimum non-combustible material clearance.
If not using hood.
You must have non-combustible materials above the fireplace
opening. Non-combustible material must extend at least 12" above
fireplace opening. With sheet metal, you must have non-
combustible material behind it.
Heat resistant materials such as slate and marble must be at least
1/2" thick. Sheet metal should not be installed onto
combustible material.
Important: If you can not meet these minimum clearances, you
must operate this heater with chimney flue damper
open, if possible. See instructions for vented
operations.
If above minimum clearances can not be obtained, you must
use a hood.
