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. Noncom-
bustible materials (such as slate, marble,
tile, etc.) must be at least 1/2 inch thick.
With sheet metal, you must have noncom-
bustible material behind it. Noncombus-
tible 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 Installing Damper Clamp Accessory for
Vented Operation, page 10.
