System Check - Jøtul GF 400 DV Sebago Installation And Operation Instructions Manual

System Check

1. PURGING THE GAS LINE: When lighting the appli-
ance for the first time, it will take a few moments to
clear the gas line of air. Once this purge is complete,
the appliance will operate as described in the
lighting instructions. See the inside back cover of
this manual or the stove Rating Plate attached the
bottom of the stove. Subsequent burner starts will
not require purging the gas line unless the supply
line is shut off.
2. PILOT FLAME: You can monitor the pilot flame
through the view port located at the rear of the
Right Log. The pilot flame should be steady - not
lifting or floating. The flame should be blue in color
around the pilot hood, , , , , with traces of yellow toward
the outer edges.
The pilot flame should engulf the top 3/8" of the
thermopile (to generate millivolt current) and the
top 1/8" of the thermocouple. The pilot flame should
project out of all three pilot hood ports 1" and
project over to the burner plate carry-over ports. See
fig. 38 and 38a.
DO NOT ATTEMPT TO ALTER THE FLAME APPEARANCE
BY POSITIONING THE GAS VALVE CONTROL IN ANY
OTHER THAN THE FULL "ON" POSITION.
3. BURNER ADJUSTMENT: This stove is equipped with a
variable gas control valve that allows easy adjustment
of the flame height appearance and heat output. To
adjust the flame between the HI and LOW setting,
rotate the HI/LOW knob, located in the center of the
valve face. Flame height will adjust approximately 1"
to 2" between the LOW and HIGH settings. See fig. 39.
NO SMOKE OR SOOT SHOULD BE PRESENT. CHECK LOG
PLACEMENT IF ANY SOOT OR SMOKE IS PRESENT. IF
SOOT OR SMOKE PERSISTS, THE AIR SHUTTER MAY
NEED TO BE ADJUSTED.
See Air Shutter/Flame Appearance section of this
manual for proper air shutter settings and adjust-
ments. Note: the more offsets there are in the vent
system, the greater the need for an air shutter adjust-
ment. See page 20.
AIR SHUTTER ADJUSTMENTS SHOULD ONLY BE
PERFORMED BY A QUALIFIED PROFESSIONAL
SERVICE TECHNICIAN.
