Derating Procedure:
To derate this unit, install the appropriate orifice as
shown in the High Altitude chart.
1. Remove the two ¼” hex head screw that holds
the burner tube/log support to the bottom of the
stove.
2. Remove the burner tube/log support to expose
the main burner orifice.
3. Remove the air deflector shield around the main
burner orifice.
4. Remove the orifice and replace with the appropri-
ate one from the high altitude kit.
5. Be sure to attach the high altitude conversion
sticker provided with the kit to the rating plate on
the appliance.
A self-adhesive Conversion Label ( Fig. 21) is
included with the High Altitude Kit. Apply this label
to the control valve after it has been converted for
high altitude.

High Altitude Adjustment
When installing the Lillehammer in high altitude
(above 2500 ft.) locations, it becomes necessary to
compensate for the thinner air (less volume of oxygen
per cubic foot). High altitudes affect the atmospheric
pressure and heat value of gaseous fuels. The lower
oxygen content in the air and the lower gas viscosity
require the use of a different orifice to achieve
efficient, clean combustion at the burner tube.
U.S. Requirements
THE DERATING KIT MUST BE INSTALLED BY AN
AUTHORIZED SERVICE TECHNICIAN IN ACCORDANCE
WITH THE MANUFACTURER’S INSTRUCTIONS AND ALL
CODES AND REQUIREMENTS OF THE AUTHORITY
HAVING JURISDICTION. THE INFORMATION STICKER
MUST BE FILLED OUT BY THE INSTALLER AND AD-
HERED TO THE APPLIANCE AT THE TIME OF THE
CONVERSION. THE QUALIFIED SERVICE AGENCY
PERFORMING THIS WORK ASSUMES RESPONSIBILITY
FOR THIS DERATING.
Canadian Requirements
This unit has been tested for installation at high
altitudes in accordance with Canadian test standard
CAN/CGA-2.17.
THE DERATING SHALL BE CARRIED OUT IN ACCOR-
DANCE WITH THE REQUIREMENTS OF THE PROVIN-
CIAL AUTHORITIES HAVING JURISDICTION AND IN
ACCORDANCE WITH THE REQUIREMENTS OF THE
CAN1-B-149.1 AND .2 INSTALLATION CODE.
For installations from 610 - 1370 meters (2000-
4500 ft.) the orifice size for natural gas is #49
and for
propane gas #56. SEE THE HIGH ALTITUDE ORIFICE
CHART
See the Rating 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 informa-
tion sticker must be filled out by the installer and
adhered to the appliance at the time of the conver-
sion.
