6. High Altitude Adjustment
The decreased atmospheric pressure of higher alti-
tudes affects heat value of gaseous fuels. Most gas
suppliers derate the gas intended for use at eleva-
tions 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
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.
INSTALLER: Fill out the appropriate information
and apply the high altitude conversion label provid-
ed to the rating plate on the appliance. See fig. 24.
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 instruc-
tions are also included in the kit.
• Conduct gas leak and gas pressure tests as de-
tailed on page 15 of this manual.
• Conduct system check and flame picture adjust-
ments as specified on pages 22-23.

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.
DO NOT OPERATE THIS STOVE
WITHOUT THE SKAMOL PANELS INSTALLED.
The labeled lower panel retainer bracket should
be removed from the firebox - it is intended only to
prevent shipping damage.
Reflective Glass Panels
• 1/4” socket driver required
• 7/16” open end or adjustable wrench
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. Loosen, but do not remove the three #8 x 12 sheet
metal screws that secure the Upper Panel Retainer.
Pull the the retainer forward about 1/4 inch. 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.
Tilt the panel to engage its upper edge
behind the retainer bracket. Seat the panel all the way
back and 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.
Cet appareil est equippé pour des altitudes compries
entre 0 et 2000 pieds (0-610 m ) seulement.
