HIGH ALTITUDE INSTALLATIONS:

When installing the Allagash in high altitude (above 2000') situations it becomes necessary to compensate for the thinner air (less volume of air per cubic foot). Higher altitudes effect 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.

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 FILLED OUT BY THE INSTALLER AND ADHERED TO THE APPLIANCE AT THE TIME OF THE CONVERSION. THE QUALIFIED SERVICE AGENCY PERFORMING THIS WORK ASSUMES RESPONSIBILITY FOR THIS DERATING.

ALWAYS TEST PRESSURES WITH VALVE CONTROL KNOB SET ON HIGH

Symptons 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 appliance causing nusance outages or gas surges.

Excessive gas pressure:

•Permanent damage to valve causing complete appliance shut down.

•Too large a pilot flame resulting in over heating of the power generator causing shut down.

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

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 REQUIREMENTS OF THE PROVINCIAL AUTHORITIES HAVING JURISDICTION AND IN ACCORDANCE WITH THE REQUIREMENTS OF THE CAN1-B-149.1

AND .2 INSTALLATION CODE.

For installations from 2000ft.(610m) to 4500ft.(1370m) the orifice size for:

natural gas is a #42 propane gas is a #55

SEE THE HIGH ALTITUDE ORIFICE CHART

on page 14.

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 by the installer and adhered to the appliance at the time of the conversion. See Figure 6.
