NOTICE: Surface temperatures of adjacent
walls and mantels become hot during opera-
tion. 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 clearances shown, you must do one
of the following:
• operate the logs only with the flue damper
open
• raise the mantel to an acceptable height
• remove the mantel

Determining Minimum Mantel Clearance When Using a
Hood
If minimum clearances in Figure 4, 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 5, when using hood.
INSTALLING DAMPER CLAMP ACCESSORY FOR
VENTED OPERATION
Note: When used as a vented indoor appliance, appliance
must be installed only in a solid-fuel burning fireplace with a
working flue and constructed of noncombustible material.
For Massachusetts Residents Only: Installation of this gas
log set as a vented indoor appliance in the Commonwealth of
Massachusetts requires the damper be permanently removed
or welded in the fully open position.
You must install the damper clamp accessory (to order, see
Accessories, page 21). This will insure vented operation (see
Figure 8). The damper clamp will keep damper open. Instal-
lation instructions are included with clamp accessory.
See chart below for minimum permanent flue opening you
must provide. Attach damper clamp so the minimum perma-
nent flue opening will be maintained at all times.
FLOOR CLEARANCES
A. If installing appliance on the floor level, you must maintain
the minimum distance of 14" to combustibles (see Figure
6).
B. If combustible materials are less than 14" to the fireplace,
you must install appliance at least 5" above the combustible
flooring (see Figure 7).
