6. High Altitude Adjustment
The decreased atmospheric pressure of higher altitudes
affects heat value of gaseous fuels. Most gas suppli-
ers derate the gas intended for use at elevations above
2000 feet. Check with your gas supplier before perform-
ing 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
Altitude Adjustment Kit 156822 for Natural gas.
DO NOT DERATE FOR PROPANE.
U.S & Canada per
ANSI Z21.88-2005•CSA 2.33-2005, 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.
Cet appareil est equippé pour des altitudes compries
entre 0 et 2000 pieds (0-610 m ) seulement.
Derating Procedure
• Follow Steps 1-6 of the Fuel Conversion procedure
on pages 16 to change the burner injector. Use the
injector 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 adjust-
ments as specified on pages 22-23.
INSTALLER: Fill out the appropriate information
and apply the high altitude conversion label provided
to the rating plate on the appliance. See fig. 24.

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 SKAMOL
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. 25.
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. 26.
4. Orient the side panels, smooth side out, and sliding
each behind the retainer wings. See Fig. 26a.
5. Push the Upper Retainer back against the glass
panels and tighten the three sheet metal screws.
6. Replace the Lower Panel Retainer.
