Flame Appearance / Air Shutter
Adjustment
WARNING:
AIR SHUTTER ADJUSTMENTS SHOULD ONLY BE
PERFORMED BY A QUALIFIED, PROFESSIONAL
SERVICE TECHNICIAN.
Locate the Primary Air Shutter control under the firebox
floor above the gas valve. See fig. 37. The shutter is set
at the midpoint of its adjustment range at the factory.
This will give good results in the majority of installation
configurations, however, you may need find it necessary
to adjust it to get the best flame picture depending upon
the your specific installation.
With the burner operating, loosen the wingnut on
the shutter stem. Push the stem back toward the rear of
the stove will decrease combustion air. Pull it forward to
increase air.
Generally, flame appearance is a matter of
individual preference, however a warm yellowish flame
is most common.
Closing the air shutter - in extreme cases may
generate very long yellow flames resulting in soot.
Sooting produces black deposits on the logs, on the
inside walls of the appliance, and potentially on the
exterior termination cap.
Sooting is caused by incomplete combustion in the
flames and lack of combustion air entering the air
shutter opening.
Opening the air shutter - will generate a flame that
is blue and transparent, or "anemic". This flame is
generally more efficient, but not as attractive.
Allow the burner to operate at the highest setting
for 20-30 minutes before making any adjustments.
Always make adjustments in 1/8" increments and
allow the burner to settle in for 10- 15 minutes
between additional adjustments.

Operation Notes
1. For the first several hours of operation, it is common
to detect some odor as the metal and manufacturing
materials cure under heat. This condition is
temporary and can be alleviated by allowing plenty
of fresh air to circulate through the area.
2. Condensation may develop on the glass upon each
lighting of the appliance. This "fog" will disappear as
the glass heats.
3. Keep the controls and the area under the appliance
free of dust. Always keep the appliance area clear
and free from combustible materials, gasoline and
other flammable liquids.
4. This appliance can be operated with a continuously
burning pilot flame. Exercise caution when using
household products containing combustible vapors.
5. CAUTION: DO NOT OPERATE THIS APPLIANCE
WITH THE GLASS 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.
NEVER USE ANY SUBSTITUTE MATERIALS.
