The appliance must be isolated from the gas supply line by closing its individual manual gas shutoff valve (gas cock) during any pressure testing of the gas supply piping system that is equal to or less than pressures of 1/2 psig (3.5 kPa).

ALWAYS TEST PRESSURE WITH VALVE CONTROL KNOB SET ON HIGH. Symptoms of incorrect gas pressure include:

Insufficient gas pressure:

Small pilot flame which can result in insufficient millivolts.

Little variation in flame picture between HI and LO settings.

Insufficient gas to support more than one appli- ance causing nuisance outages or gas surges.

Excessive gas pressure:

Permanent damage to valve causing complete appliance shut down.

Too large a pilot flame resulting in overheating of the power generator and consequent shut down.

Sooting due to impingement and/or incorrect fuel to air mix.

High Altitude Adjustment

Installations located at altitudes from 2000 - 4500 ft. (610 M - 1370 M), require compensation 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 combus- tion 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 (#155610-NG / #155611-LP).

In the U.S: THE DERATING KIT MUST BE INSTALLED BY AN AUTHORIZED SERVICE TECHNICIAN IN ACCOR-

DANCE WITH THE MANUFACTURER’S INSTRUCTIONS AND ALL CODES AND REQUIREMENTS OF THE AUTHORITY HAVING JURISDICTION. THE INFORMA- TION STICKER MUST BE COMPLETED BY THE IN- STALLER AND APPLIED TO THE APPLIANCE AT THE TIME OF THE CONVERSION. THE QUALIFIED SERVICE AGENCY PERFORMING THIS WORK ASSUMES RE- SPONSIBILITY FOR THIS DERATING.

In Canada: 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 ACCORDANCE WITH THE REQUIRE- MENTS 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 1-4 of the Fuel Conversion procedure outlined on page 14.

2.Remove the original orifice. Consult Table 1 to determine the correct orifice size for your eleva- tion and fuel type. Install the appropriate orifice included in the high altitude kit.

3.Fill out the high altitude conversion label and attach to the rating plate or fireplace cabinet floor See Figure 27.

4.Reassemble the firebox components.

5.It may be necessary to adjust the air shutter on the burner tube. See the AIR SHUTTER/FLAME APPEARANCE section of this manual for more details.
