INSTALLATION
Continued
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, page 11, 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 hood.
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
FLOOR CLEARANCES
A. If installing appliance on the floor level, you
must maintain the minimum distance of 14"
to combustibles (see Figure 8).
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).

INSTALLING DAMPER CLAMP
ACCESSORY FOR VENTED
OPERATION
Note: When used as a vented heater, appliance
must be installed only in a solid-fuel burning
fireplace with a working flue and constructed of
noncombustible material.
If your heater is a manually-controlled model, you
may use this heater as a vented product. There
are three reasons for operating your heater in the
vented mode.
1. The fireplace does not meet the clearance
to combustibles requirements for vent-free
operation.
2. State or local codes do not permit vent-free
operation.
3. You prefer vented operation.
If reasons number 1 or 2 above apply to you, you
must permanently open chimney flue damper. You
must install the damper clamp accessory (to order,
see Accessories, page 42). This will insure vented
operation (see Figure 10, page 13). The damper
clamp will keep damper open. Installation instruc-
tions are included with clamp accessory.
See chart on next page for minimum permanent
flue opening you must provide. Attach damper
clamp so the minimum permanent flue opening
will be maintained at all times.
