Proper Combustion
Furnace should operate minimum 15 minutes with correct
manifold pressure and gas flow rate before checking
combustion. Take combustion sample beyond the flue outlet
and compare to the tables below. The maximum carbon
monoxide reading should not exceed 100 ppm.

*Conversion requires installation of a gas valve manifold spring which is provided with the gas conversion kit.
Pressure switch is factory set. No adjustment necessary. All models use the factory-installed pressure switch from 0-4500 feet (0-1371 m).

High Altitude Information
NOTE: In Canada, certification for installations at elevations
over 4500 feet (1371 m) is the jurisdiction of local authorities.
Units may be installed at altitudes up to 10,000 ft. above
sea level without manifold adjustment. Units installed
at altitude of 4501 - 10,000 feet (1371 to 3048 m) may
require a pressure switch change which can be ordered
separately. Table 17 lists conversion kit and pressure switch
requirements at varying altitudes.
The combustion air pressure switch is factory-set and
requires no adjustment.
NOTE: A natural to LP/propane gas changeover kit is
necessary to convert this unit. Refer to the changeover kit
installation instruction for the conversion procedure.
