BURNER FLAME
ADJUSTMENT
Figure 29 - Correct Pilot Flame Pattern
The main burner flame should be a blue flame
somewhere between a long blue flame and a
short, sharp flame that tends to blow off the
ports. If flame is short, very sharp or blowing,
the burner air shutter should be closed enough
to obtain a long blue flame (see Figure 30).
Long yellow flame produce excess carbon
monoxide and could cause sooting.
TO SHUT OFF
1. For temporary shutoff, turn off electri-
cal power to unit either by wall switch
or remote control.
2. For long term shutoff, depress the gas
valve cock valve, located under the fire-
box, turn clockwise to the OFF position.

Thermopile
Pilot Burner
1. Upon completing your gas line connec-
tion, a small amount of air will be in
the lines. When first lighting the appli-
ance it will take the appliance a few
minutes to purge the air. Once purging
is complete, the pilot and burner will
light and operate as indicated in the
instruction manual. Subsequent light-
ing of the appliance will not require
such purging.
1. When lit for the first time, the appli-
ance will emit a slight odor for an hour
or two. This is due to the “curing” of
the logs and “burn-in” of internal paints
and lubricants used in the manufactur-
ing process.
2. Keep control compartment, logs burn-
ers, and area surrounding the logs
clean by vacuuming or brushing at
least twice a year. Do not vacuum the
mineral wool located in the front of
the burner assembly.
3. Always turn off gas to pilot before
cleaning. For example relighting, refer
to the lighting instructions.
4. A qualified field service technician should
inspect the appliance and venting system
before use or at least annually.
5. Always keep the appliance area clear
and free from combustible materials,
gasoline and other flammable vapors
and liquids.
6. Never obstruct the flow of combustion
and ventilation air. Keep the front of
the appliance clear of all obstacles and
materials.
7. Never leave children unattended when
the appliance is operating.
WARNING: Turn off gas and
electrical power before servicing
appliance. It is recommended that
a qualified serviceman perform
these checkups at the beginning
of each heating season.
In order to properly clean the burner and
pilot assembly remove the logs exposing the
burner and pilot assembly.
CLEANING BURNER AND
PILOT
Clean all foreign materials from the top of
burner and from bottom panel below. Check
to make sure that burner orifice is clean.
Visually inspect pilot. Brush or blow away
any dust and lint accumulations. If pilot
orifice is plugged, disassembly maybe re-
quired to remove any foreign materials from
orifice and/or tubing. When appliance is put
back in service, check pilot flame patterns
(see Figure 29).
