Flame Picture Adjustment - Jøtul GF 370 DV Installation And Operation Instructions Manual

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 fire-
box 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 indi-
vidual 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 com-
mon to detect some odor as the metal and manu-
facturing 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 continu-
ously 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
