HIGH ALTITUDE DERATE
Input ratings (BTUH) of these Furnaces are based on sea
level operation and should not be changed at elevations up to
2,000 ft.
If the installation is 2,000 ft. or above, the Furnace input rate
(BTUH) shall be reduced 4% for each 1,000 ft. above sea level.
The Furnace input rate shall be checked by clocking the gas
flow rate (CFH) and multiplying by the heating value ob-
tained from the local utility supplier for the gas being deliv-
ered at the installed altitude. Input rate changes can be
made by adjusting the Manifold Pressure (min 3.0 - max 3.7
in. W.C. - Natural Gas) or changing orifices (orifice change
may not always be required).
If the desired input rate can not be achieved with a change in
Manifold Pressure, then the orifices must be changed. LP
installations will require an orifice change.
IMPORTANT: Reinstall the replacement orifices to the same
depth as the orifices supplied with the equipment.
See Table 19 for help in selecting orifices if orifice change is
required. Furnace input rate and temperature rise should be
checked again after changing orifices to confirm the proper rate
for the altitude.
The vent length table on page 19 shows the required vent
lengths for installations at various altitudes. An optional
high altitude kit is available for installations above 5000
feet. Installations above 12,000 feet are not allowed.

Turn the main Gas Valve toggle switch (See Figures 30 & 31)
within the unit to the “OFF” position. Turn the external gas
valve to “ON”. Purge the air from the gas lines. After purging,
check all gas connections for leaks with a soapy solution -- DO
NOT CHECK WITH AN OPEN FLAME. Allow 5 minutes
for any gas that might have escaped to dissipate.
LP Gas being heavier than air may require forced ventilation.
Turn the toggle switch on the Gas Valve in the unit to the “ON”
position.
If your application requires a high altitude pressure switch
use Table 20 to select the appropriate kit for your model
furnace.
