TABLE 6 - HIGH ALTITUDE SPECIFICATIONS
Gas input ratings are certifi ed for elevations to 5400 ft. (1646 m) on natural gas. For elevations above 5400 ft. (1646 m) on natural gas, or
LP fuel source above 2000 ft. (610 m), follow orifi ce derate chart above.

H18.1B
In Canada, this funace does not need to be converted for high altitude (2000-4500ft), when the fuel source
is natural gas. It has been certi
fi ed to operate at high altitude as manufactured. If the fuel source is liquid
propane, refer to High Altitude Speci fi cations table for appropriate derate above 2000ft based on a 4%
reduction of input capacity for every 1000ft above sea level.
In the United States, this furnace does not need to be converted for high altitude from (2000-5400ft), when
the fuel source is natural gas. It has been certi
fi ed to operate at high altitude as manufactured up to 5400ft
only. Beyond 5400ft the modi fi cations are based on a 4% reduction of input capacity for every 1000ft above
sea level. If the fuel source is liquid propane, refer to High Altitude Speci fi cations table for appropriate derate
above 2000ft based on a 4% reduction of input capacity for every 1000ft above sea level. Consult with local
fuel suppliers or authorities to determine local regulations or customs.
H18.2A
This series furnace is manufactured as a natural gas appliance that may be converted to LP gas through use of
the
Conversion Kit part number W370-0018 . This kit contains the conversion kit instructions, ori fi ces needed
for all models, the regulator spring for the gas valve, and a label to af fi x adjacent to the appliance rating plate to
alert subsequent service technicians of the conversion. The parts removed for this conversion must remain
with the furnace for any future conversion back to natural gas.
H18.3
Refer to Conversion NG to LP Kit (W370-0018) for complete instruction.
WHITE-RODGERS 36G54 TWO STAGE GAS VALVE
1. Turn off the gas and electrical supply to the furnace.
2. Back inlet pressure test screw (inlet pressure boss, see FIGURE 31) counterclockwise out one turn
maximum, with a 3/32” Allen wrench. Attach a hose and calibrated U-tube or digital manometer to the inlet
pressure boss. Hose should overlap boss 3/8”. The manometer must have a scale range of at least 0” to
15” of water column.
3. Turn ON the gas and electrical supply and operate the furnace and all other gas consuming appliances on
the same gas supply line. Using a leak detection solution, check for leaks around the gas valve/manifold
connection and the burner ori
fi ces. Repair any leaks before continuing.
4. Measure furnace gas inlet pressure with burners fi ring. Inlet pressure must be within the range speci fi ed
on the furnace rating plate. 5-7” w.c. (Natural Gas) or 11-13” w.c. (LP).
If the inlet pressure differs from the rating plate, make the necessary adjustments to pressure regulator,
gas piping size, etc. and/or consult with local gas utility.
