Intake Air Adjustment
An Intake Air shutter plate allows further burner
adjustment for taller vent runs. It is located under the
firebox floor and is set fully open at the factory. See
fig. 16.
The shutter has an adjustment range of 1 inch.
To change the setting, loosen the wingnut and slide
the gasketed shutter stem backward to the half or
fully closed positions, depending on which vent zone
is appropriate. Retighten the wingnut before lighting
the burner to seal the gasket. Allow the flame pattern
to settle in for 10- 15 minutes between each setting
change.

vent adaptor collar.
Exhaust Restrictor Adjustment
1. Remove the Trim Rings from the Top Plate.
2. Loosen the locking screw and turn the restrictor
pivot plate to the appropriate indicator point as
specified in the vent window diagram, figure 17.
After the burner has been operating for 15 minutes,
make any further adjustment in 1/8” increments
until the desired flame picture is achieved.
Do not
exceed the fully closed setting as shown in fig. 15.
Operate the burner for 10-15 minutes between ad-
ditional adjustments.
3. Tighten the locking screw and replace the Trim
Rings.
Vent Restriction Adjustments
The Jøtul GF
370
DV II features adjustment controls for
both intake air and exhaust to accommodate a variety
of conditions that result from variables inherent in the
vent configuration and environment. Both controls
can be accessed from outside the firebox to allow the
burner to be “dialed-in” under operation. See figures 14
and 16.
Use the Vent Termination Diagram, fig. 17, to
determine which zone your vent termination falls
within and make the appropriate exhaust and air
intake setting adjustments. Use these settings as
general guidelines to start from. The final settings
will ultimately be determined by the individual
characteristics of your particular installation.
There are no hard and fast rules.

Zone D
Vent terminations within Zone D are susceptible
to draft conditions that may interfere with the
intermittent Pilot Ignition functionality. In such
cases, we recommend that the stove be operated
only in Continuous Pilot Ignition mode.
Exhaust Vent Restriction
Exhaust restriction prevents overly strong draft
that can interfere with pilot function, cause poor
combustion or a weak flame picture. The shutter is
set in the fully open position at the factory. The final
position of the restriction shutter is determined by
where the vent termination falls within the vent
window diagram.
For example, if the vent rise is 20 feet and
includes one elbow in a horizontal run of 5 feet, the
appropriate exhaust setting will be Full Restriction.
