If Using Mantel
You must have noncombustible material(s) above
the fireplace opening. Noncombustible materials
(such as slate, marble, tile, etc.) must be at least 1/2
inch thick. With sheet metal, you must have non
-
combustible material behind it. Noncombustible
material must extend at least 8" up. If noncombus
-
tible material is less than 12", you must install the
fireplace hood accessory. Even if noncombustible
material is more than 12", you may need the hood
accessory to deflect heat away from your mantel
shelf. See Figure 5 and Figures 6 and 7 on page
11 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 12.

Noncombustible material
must be extended to at
least 8". See
Between 8"
and 12"
, above. If you
cannot extend material,
you must operate heater
with flue damper open.
MANTEL CLEARANCES
In addition to meeting noncombustible material
clearances, you must also meet required clearances
between fireplace opening and mantel shelf. If
you do not meet the clearances listed below, you
will need a hood.
Determining Minimum Mantel Clearance
If you meet minimum clearance between mantel
shelf and top of fireplace opening, a hood is not
required (see Figure 6, page 11).
DETERMINING MINIMUM MANTEL
CLEARANCE WHEN USING A HOOD
If minimum clearances in Figure 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 Figure 7,
page 11, when using a hood.
FLOOR CLEARANCES
A. If installing appliance on the floor level, you
must maintain the minimum distance of 14"
to combustibles (see Figure 8, page 11).
B. If combustible materials are less than 14" to
the fireplace, you must install appliance at
least 5" above the combustible flooring (see
Figure 9, page 11).
NOTICE: Surface temperatures
of adjacent walls and mantels
become hot during operation.
Walls and mantels above the
firebox may become hot to
the touch. If installed properly,
these temperatures meet the
requirement of the national
product standard. Follow all
minimum clearances shown in
this manual.
NOTICE: If your installation does
not meet the minimum clear-
ances shown, you must do one
of the following:
• operate the logs only with the
flue damper open
• raise the mantel to an accept-
able height
• remove the mantel
