Maintenance
Keep the control compartment, logs and burner area
surrounding the logs clean by vacuuming or brushing
at least twice a year.
THE LOGS CAN GET VERY HOT
— HANDLE ONLY WHEN COOL.
Always turn off gas to the pilot before cleaning. For
relighting, refer to lighting instructions located on the
front cover plate.
Never obstruct the flow of combustion and ventilation
air. Keep the front of the appliance clear of all obstacles
and materials.
Leave at least 36" clearance from front of appliance to
combustibles. Refer to page 3.
Cleaning the Standing
Pilot Control System
The burner and control system consists of:
• main burner
• gas orifice
• pilot burner
• thermopile
• combination millivolt gas valve
• thermocouple
Most of these components may require only an occa-
sional checkup and cleaning and some may require ad-
justment. If repair is necessary, it should be performed
by a qualified technician.
In order to properly clean the burner and pilot assem-
bly, turn off the gas to the unit, open the glass door
(if used), remove logs exposing the burner and pilot
assembly. Clean all foreign materials from the top of the
burner. Check to make sure that burner parts are clean.
Visually inspect pilot. Brush or blow away any dust or
lint accumulation If pilot orifice is plugged, disassembly
may be required to remove any foreign material from
the orifice or tubing.
To obtain proper operation, it is imperative that the pilot
and burner's flame characteristics are steady, not lifting
or floating.
Typically, the top 3/8" or 1/2" of the thermopile should
be engulfed in the pilot flame. (Fig. 19)
To adjust pilot burner, turn pilot screw marked "pilot" for
proper flame size.
The air shutter is set at factory no adjustment should be
necessary.
Cleaning Electronic Ignition System
The Electronic Ignition burner/control system consists
of:
• main burner
• gas orifice
• pilot burner
• 24VAC valve with transformer
Taking care of the Electronic Ignition units is almost
identical to taking care of the Standing Pilot models.
