13.1 HIGH ALTITUDE CONVERSION
H18.1.2
In Canada and the United States, this furnace is certi
fi
ed to 2000 feet (610m) on natural gas only. In the
United States of America above 2000 feet, the modi
fi
cations for high altitude are based on a 4% reduction of
input capacity for every 1000 feet (305m) above sea level. In Canada units above 2000 feet (610m) will need
to be derated 10%. Table 6 illustrates the impact of altitude for selected elevations. Consult with local fuel
suppliers or authorities to determine local regulations or customs.

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).
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.
5. Turn off gas and electrical supply to furnace, remove the manometer hose from the inlet pressure tap
boss, and tighten the inlet pressure tap screw using the 3/32” Allen wrench. (Clockwise, 7 in-lb minimum).
6. Turn on the gas supply and electrical power to the furnace.
