High Altitude Adjustment
Installations burning natural gas and located at altitudes
from 2000 - 4500 ft. (610 M - 1370 M), require compen-
sation for the thinner air (less volume of air per cubic
foot). Higher 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.
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, use Jøtul High Altitude Kit,
#155885-LP or # 155895 NG.
DO NOT DERATE THE BURNER FOR PROPANE.
In the U.S: 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
COMPLETED BY THE INSTALLER AND APPLIED TO THE
APPLIANCE AT THE TIME OF THE CONVERSION. THE
QUALIFIED SERVICE AGENCY PERFORMING THIS WORK
ASSUMES RESPONSIBILITY FOR THIS DERATING.
In Canada: This unit has been tested for installation at
high altitudes in accordance with Canadian test stan-
dard CAN/CGA-2.17. THE DERATING SHALL BE CARRIED
OUT IN ACCORDANCE WITH THE REQUIREMENTS OF THE
PROVINCIAL AUTHORITIES HAVING JURISDICTION AND
IN ACCORDANCE WITH THE REQUIREMENTS OF THE
CAN1-B-149.1 AND .2 INSTALLATION CODE.

Derating Procedure
1. Follow Steps 1-10 of the Fuel Conversion procedure
outlined on pages 11 and 12.
2. Replace the original orifice with the appropriate orifice
in the kit: 3.10 mm NG or #51 LP.
3. Fill out the high altitude conversion label from the kit
and attach to the rating plate or gas valve.
4. Reassemble the firebox components.
5. It may be necessary to adjust the air shutter on the
burner tube. See AIR SHUTTER/FLAME APPEARANCE
on page 16 for more details.
