High Altitude 

Capacity Changes 

5.

 With the heater operating determine that the inlet pressure to the heater for natu

-

ral gas is between 5 and 13.5 inches w.c. and for propane between 10 and 13.5 

inches w.c. Take this reading as close as possible to the heater (Heaters are 

equipped with gas valves that have an inlet pressure tap.) If the inlet pressure is 

not within the specified range, the inlet pressure must be corrected and Steps 3 

and 4 repeated.

6.

 Find the High Altitude Adjustment label in the plastic bag that contained these 

instructions. Using a permanent marker, fill-in the appropriate information from the 

tables below. Select a location for the label on the outside of the heater access 

panel so that it will be conspicuous to anyone operating or servicing the unit. Be 

sure the surface is clean and dry and adhere the label.

The input and/or the capacity of the heater changes with the derate. The tables below 

list inputs and capacities at altitudes from sea level to 10,000 ft (3045M).
