Fireplace Operation
Burner Controls
•
Burner functions may be manually controlled by plac-
ing the burner switch in the ON/OFF position.
•
The STAT position permits automatic control through
use of an optional wall thermostat or remote control
device. Fig. 33.
Pilot Modes
Two distinct burner ignition modes permit greater
operational flexibility under a variety of conditions.
• Continuous Pilot Ignition ( CPI )
In this mode, the pilot continues burning even when
there is no call for heat. This feature permits the
burner to ignite smoothly and continue to function
under a variety of adverse conditions. For example, it
can be difficult to establish positive draft through a
very long vent system, particularly in colder weather.
In such cases, the entire system will benefit from
the heat generated by a continuously burning pilot
flame. The slight expense of running the pilot is
offset by the improved functionality of the appliance.
Exercise caution when operating with a continuous
pilot. DO NOT USE CLEANING PRODUCTS HAVING
COMBUSTIBLE VAPORS AROUND THE OPERATING
FIREPLACE.
• Intermittent Pilot Ignition ( IPI )
This mode allows the pilot flame to go out
when there is no call for heat. Ideal for use with
thermostatic or remote control, this feature ignites
the pilot flame only when there is a call for heat. A
battery back-up permits continued use in the event of
a power failure.
NOTE: If the unit performs better in CPI mode, or cannot
be operated in IPI mode, consider installing a high-
efficiency pilot orifice.

Flame Picture
The gas control valve regulator provides easy adjustment
of flame height, appearance, and heat output. To adjust
the flame between the HI and LO setting, rotate the HI/LO
knob, located on the valve face.
NO SMOKE OR SOOT SHOULD BE PRESENT. IF THERE
IS EVIDENCE OF EITHER SMOKE OR SOOT, CHECK THAT THE
BURNER MEDIA IS NOT BLOCKING THE AIR GAP IN THE
BURNER TRAY. IF SOOT OR SMOKE PERSIST, THE AIR SHUT-
TER MAY REQUIRE ADJUSTMENT.
See figs. 21 -22 on page 19 for correct burner flame
depictions.

NOTE: THE FUNCTIONALITY OF THE IPI SYSTEM IS
DEPENDANT UPON A NUMBER OF VARIABLES UNIQUE
TO YOUR SPECIFIC INSTALLATION. THESE INCLUDE TALL
CHIMNEYS, WINDY ENVIRONMENTS, AND VERY COLD
OUTSIDE TEMPERATURES. SUCH CONDITIONS CAN
RESULT IN PILOT AND/OR BURNER MALFUNCTION.
IF THIS SHOULD OCCUR, OPERATE THE APPLIANCE IN CPI
MODE. SEE BELOW FOR DETAILS.
