System Check - Jøtul GF 300 DV 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. From a cold start, it may be
helpful to let the pilot light burn for 10 - 15 minutes
to establish positive draft, before turning the burner
on. See the inside back cover of this manual or the
stove Rating Plate attached to therear shroud.
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. See fig. 37. 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 over to
the burner plate carry-over ports. See figs. 37 and
37a.
3. BURNER ADJUSTMENT: This stove is equipped with a
variable gas control valve that allows easy adjust-
ment of the flame height and heat output. To adjust
the flame intensity, rotate the HI/LOW knob.
Flame height will adjust approximately 50% be-
tween the LOW and HIGH settings. See fig. 38.
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
adjustment. See page 20.
AIR SHUTTER ADJUSTMENTS SHOULD ONLY BE
PERFORMED BY A QUALIFIED PROFESSIONAL
SERVICE TECHNICIAN.
