GENERAL

• These high altitude conversion kits are to be used only with L8 natural gas furnace models only.
• These instructions describe the conversion of these furnaces for installations exceeding an altitude of 4000 feet above sea level.
• Due to the lower density of air at higher altitudes, there would be insufficient negative pressure developed by the induced draft blower to maintain normal operation. Therefore, to compensate for the less dense air, the Personality Module must be changed to prevent nuisance lockouts and/or cycling of the induced draft blower on high speed. Please note that with the reduced firing input rates required for high altitude installations, the induced draft blower has ample capacity to provide sufficient combustion air for proper and safe operation.
• Refer to the National Fuel Gas Code – latest Edition 11.1.2 – High Altitude and Table E.1.1(d).

CAUTION

• Before proceeding with the conversion, the gas supply must be shut off prior to disconnecting the electrical power.
