Minimum Non-combustible
Material Clearances
If Not Using Mantel
You must have non-combustible material(s)
above the fireplace opening. Non-combus-
tible materials (such as slate, marble, tile,
etc.) must be at least 1/2 inch thick. With
sheet metal, you must have non-combus-
tible material behind it. Non-combustible
material must extend at least 8" up (for all
models). If non-combustible material is less
than 12", you must install the fireplace hood
accessory (24", 30", and 36” models only).
See Figure 4 on page 7 and Figure 5 for
minimum clearances.
IMPORTANT: If you cannot meet these
minimum clearances, you must operate
heater with chimney flue damper open. Go
to Installing Damper Clamp Accessory for
Vented Operation, page 10.
If Using Mantel

sheet metal, you must have non-combus-
tible material behind it. Non-combustible
material must extend at least 8 inches up (for
all models). If non-combustible material is
less than 12", you must install the fireplace
hood accessory (24", 30”, and 36" models

minimum clearances, you must operate
heater with chimney flue damper open. Go
