High Altitude Adjustment - Jøtul GF 370 DV MV Installation And Operation Instruction Manual

130102- 1 GF 370 DV MV 2/22

6. High Altitude Adjustment

The decreased atmospheric pressure of higher altitudes af-
fects heat value of gaseous fuels. Most gas suppliers derate
the gas intended for use at elevations above 2000 feet.
Check with your gas supplier before performing derate
adjustment to the burner.
This appliance may be adjusted for altitude over 2000 ft.
(610 - 1371 m) for natural gas.
If the gas supplier does not derate fuels, install High Alti-
tude Adjustment Kit 156822 for Natural gas.
DO NOT DERATE FOR PROPANE.
U.S & Canada per
ANSI Z21.88-2019•CSA 2.33-2019, CAN/CGA 2.17
For natural gas installations from 610-1370 meters
(2000-4500 ft.) the orifice size (DMS) is #39. See
data plate for additional information. For high altitude
installations consult the local gas distributor or the
authority having jurisdiction for proper rating methods.
If the installer must convert the unit to adjust for varying
altitudes, the information sticker must be filled out and
applied to the appliance at the time of the conversion.
Derating Procedure
• Follow Steps 1-16 of the Fuel Conversion procedure on
pages 16 to change the burner injector. Use the injec-
tor supplied with the kit. Detailed instructions are also
included in the kit.
• Conduct gas leak and gas pressure tests as detailed on
page 15 of this manual.
• Conduct system check and flame picture adjustments as
specified on pages 21-22.
INSTALLER: Fill out the appropriate information and
apply the high altitude conversion label provided to the
rating plate on the appliance. See fig. 7.8.

7. Firebox Panel Installation
Skamol Panels and optional
Reflective Glass Kit 156817
Skamol Panels
These insulating panels are installed at the factory. If
desired, the panels may be painted black using any high-
temperature paint.
THE SKAMOL PANELS MUST BE LEFT IN PLACE.
DO NOT OPERATE THE STOVE WITHOUT THE SKA-
MOL PANELS INSTALLED.
Reflective Glass Panels
Tools: 1/4" socket driver
Optional: High-temp Black Paint may be applied to the
exposed edges of the side Skamol panels to match the black
glass.
Cotton gloves are provided with the glass panels. Use them
to handle the panels to prevent fingerprints on the surfaces.
Fingerprints are difficult to remove. Use a clean cloth to remove
any dust from the glass panels.
1. Remove the Upper Retainer Bracket from the firebox
with removal of three #8 x 12 sheet metal screws. See
fig. 7.9.
2. Remove the Lower Panel Retainer from the back of the
burner skirt with removal of three #8 x 12 sheet metal
screws.
3. Orient the rear panel, smooth side out, textured side
in. Rest the bottom of the panel on the burner skirt,
centered against the back wall. See fig. 7.10.
4. Orient the side panels, smooth side out, and sliding each
behind the retainer wings. See Fig. 7.11.
5. Push the Upper Retainer back against the glass panels
and tighten the three sheet metal screws.
6. Replace the Lower Panel Retainer.
