8.0 Operation
READ AND UNDERSTAND ALL OPERATING
INSTRUCTIONS BEFORE ATTEMPTING TO OPERATE
THIS APPLIANCE. DO NOT ALLOW ANYONE TO
OPERATE THIS APPLIANCE WHO HAS NOT READ
AND UNDERSTOOD THESE INSTRUCTIONS. KEEP
THE REMOTE CONTROL TRANSMITTER WHERE
CHILDREN CANNOT REACH IT.
SEVERE INJURY. THIS APPLIANCE CAN BE SET TO
OPERATE THERMOSTATICALLY. BE AWARE THAT
THE APPLIANCE MAY BE VERY HOT EVEN WHEN
THE BURNER IS NOT APPARENTLY OPERATING.
KEEP CHILDREN AWAY FROM THE APPLIANCE.
n
During the first few hours of operation, it is common to detect
some smoke and odor resulting from the high-temperature
paint curing. This condition is temporary and may be alleviated
by opening windows and using a fan to exhaust air out of the
area.
n
Condensation will develop on the glass each time the burner
ignites from a cold start. This "fog" will dissipate as the glass
heats. Leaving the pilot on during the heating season will
minimize condensation.
n
IMPORTANT: It will be necessary to clean the glass after the
first few fires. A white powdery residue will be evident which
results from the burner media curing.
Use a non-abrasive household glass cleaner or warm water.
IF THE GLASS IS NOT CLEANED, THIS RESIDUE CAN
CAUSE THE GLASS TO BECOME PERMANENTLY
ETCHED. DO NOT USE AMMONIA-BASED CLEANERS.
n NOTE GI 645 DV MV MODEL: This appliance can be
operated with a continuously burning pilot flame for up to
seven days after which the flame will automatically extinguish
if there has been no call for heat within that time period.
Relight the pilot manually following the instructions on the
back cover and rating plate.
n
Keep the control compartments free of dust and debris. Always
keep the appliance area clear and free from combustible
materials, or flammable liquids.
n
Exercise caution when using household products containing
combustible vapors when the pilot is burning.
n
CAUTION: DO NOT OPERATE THIS APPLIANCE WITH
THE GLASS PANEL REMOVED, CRACKED OR BROKEN.
REPLACEMENT OF THE GLASS SHOULD BE DONE BY
A LICENSED OR QUALIFIED SERVICE PERSON. USE
ONLY REPLACEMENT GLASS PROVIDED BY YOUR
AUTHORIZED JØTUL DEALER. DO NOT SUBSTITUTE ANY
OTHER TYPE OF GLASS.

WARNING:
WARNING:
8.1 Initial System Check and
General Operation
Service should only be performed by a
licensed gas service technician. If these
instructions are not followed exactly, a
fire, explosion, or production of carbon
monoxide may result causing property
damage, personal injury or loss of life.
1. Initial System Purge:
Open the gas supply line valve. Make sure glass frame is
removed prior to system purge. When lighting the appliance
for the first time, or after a long period of unuse, it will take
a few moments to clear the gas line of air.
2. Light the Pilot:
Once this purge is complete, light the pilot following the
lighting instructions located on the rating plate and back
cover of this manual.
All three pilot flames should project out of the pilot hood.
The flames should be blueish-yellow in color and extend
approximately 1" over to the burner
ports, thermopile, and thermocouple.
Each flame should be strong and steady
- not fluttering or lifting. It is important
that the pilot flame fully engulf the
upper 1/4" of the thermocouple and
thermopile. See Fig. 8.2.
The pilot flames may be adjusted if
necessary using the adjustment screw
located on the gas valve body, Fig. 7.2.1,
page 15. Pilot adjustments should only
be made by a qualified gas technician.

in a cold flue, it may be necessary to allow the pilot to burn
for 10-15 minutes to establish draft before main burner
ignition.
A) Set the gas valve regulator to LOW.
B) Cold Start: Turn the burner switch to ON and countdown
in seconds the time for full burner ignition; that is, all burner
ports are projecting flame. Full burner ignition should occur
within 4 seconds of switching ON. See troubleshooting guide
if greater than 4 seconds.
Reinstall the glass frame prior to hot start testing.
C) Hot Start: After the burner has been on for 5-10 minutes,
turn it off and wait 2 minutes. Turn it on and again record the
time for full ignition. Full burner ignition should occur within
4 seconds of switching ON. Test condition with burner on low.
See troubleshooting guide if greater than 4 seconds.
Adjust the valve Regulator knob to control fire intensity and
heat output.
