Start-Up Procedure
Start the furnace using the procedures in the section
"Operating Your Furnace".
WARNING: Danger of bodily injury or death.
propane gas is heavier than air and it will settle in
any low area, including open depressions and it will
remain there unless the area is ventilated.
Never attempt to start-up the unit before thoroughly
ventilating the area.
Check the furnace operation as outlined in the following
instructions.
CHECK GAS INPUT AND PRESSURES
For furnaces located at elevations between sea level and
2,000 feet, the measured input must not be greater than
the input shown on the rating plate of the furnace. For
elevations above 2,000 feet, the measured input must not
exceed the input on the rating plate reduced by 4 percent
for each 1,000 feet that the furnace is above sea level.
Gas supply pressure and manifold pressure with the
burners operating is specified on the rating plate.
Rated input will be obtained on a heating value of 2,500
BTU/hr. for propane at 10-inches manifold pressure with
factory-sized orifices. If L.P. Gas having a different heating
value is supplied, orifices must be changed by a qualified
service technician before the furnace is operated.
