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 Table 16.

Pressure switch is factory set. No adjustment necessary. All models use the factory-installed pressure switch from 0-4,500 feet (0-
1,370 m).

High Altitude
NOTE: In Canada, certification for installations at elevations
over 4500 feet (1372 m) is the jurisdiction of local authorities.
Units may be installed at altitudes up to 10,000 ft. above
sea level. See Table 14 for de-rate manifold values. Units
installed at altitude of 7501 - 10,000 feet require an orifice
change. Units installed at altitudes of 4501 - 10,000 feet (1373
to 3048 m) require a pressure switch change which can be
ordered separately. Table 17 and Table 18 list conversion kit
and pressure switch requirements at varying altitudes.
The combustion air pressure switch is factory-set and
requires no adjustment.
