INSTALLATION
Continued
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 and damper
clamp installed
• raise the mantel to an accept-
able height
• remove the mantel

ACCESSORY FOR VENTED
OPERATION
Note: When used as a vented decorative,
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 non-thermostatically con-
trolled 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
27). This will insure vented operation (see Fig-
ure 10). The damper clamp will keep damper
