Turn on gas supply and test for gas leaks using a
gas leak test solution (also referred to as bubble
leak solution).
Note:
Using a soapy water solution
(50% dish soap, 50% water) is an effective leak
test solution but it is not recommended, because
the soap residue that is left on the pipes/fi ttings
can result in corrosion over time.
A. Light the appliance
(refer to the lighting
instructions provided in the Homeowner's
Care and Operation Instructions).
B. Brush all joints and connections with the gas
leak test solution to check for leaks. If bubbles
are formed, or gas odor is detected, turn the
gas control knob (off/pilot/on) to the “OFF”
position. Either tighten or refasten the leaking
connection, then retest as described above.
C. When the gas lines are tested and leak free be
sure to rinse off the leak testing solution,
D. Turn on burner then observe the individual
tongues of fl ame on the burner. Make sure
all ports are open and producing fl ame evenly
across the burner. If any ports are blocked, or
partially blocked, clean out the ports.
Step 14. CHECKING APPLIANCE OPERA-
TION
With gas line installed run initial system
checkout before closing up the front of
the unit. Follow the pilot lighting instruc-
tions provided in the Homeowner's Care
and Operation Instructions (or pull out the
instruction label located in a holder on rear
shield of stove) . For piezo igniter location
see
Figure 30
.
Fasten the two latches located beneath the
fi rebox fl oor to the glass frame vee-fl ange.
Close both the latches securely.
Step 13. TEST ALL CONNECTIONS FOR
LEAKS (FACTORY AND FIELD).
WARNING
Never use an open fl ame to
check for leaks.
Step 15. BURNER ADJUSTMENTS
Flame Appearance and Sooting
Proper fl ame appearance is a matter of taste.
Generally, most people prefer the warm glow
of a yellow to orange fl ame.
Appliances operated with air shutter openings
that are too large will exhibit fl ames that are
blue and transparent. These weak, blue and
transparent fl ames are termed anemic. If the
air shutter opening is too small sooting may
develop.
The fl ame should project 1" (25 mm) beyond
the hood at all three ports
(
Figure 32
).
Replace logs if removed for pilot inspection.
To light the burner, rotate the gas valve control
knob counterclockwise to the “ON” position
then turn “ON” the ON/OFF rocker switch.

The pilot fl ame should be steady, not lifting
or fl oating. Flame should be blue in color with
traces of orange at the outer edge. The top 3/8"
(10 mm) at the pilot generator (thermopile)
and the top 1/8" minimum (tip) of the quick
drop out thermocouple should be engulfed
in the pilot fl ame.
