INSTALLATION
NOTICE: Surface temperatures of
adjacent walls and mantels be-
come hot during operation. Walls
and mantels above the firebox
may become hot to the touch. If
installed properly, these tem-
peratures 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

must maintain the minimum distance of 14"
to combustibles (see Figure 8).

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.
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 com-
bustibles 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 31). This will insure vented
operation (see Figure 10). The damper clamp will
keep damper open. Installation instructions are
included with clamp accessory.
See chart below for minimum permanent flue
opening you must provide. Attach damper clamp
so the minimum permanent flue opening will be
maintained at all times.
