Alternate Electrical and Gas Line Connections

This furnace has provisions allowing for electrical and gas line
connections through either side panel. In horizontal applica-
tions the connections can be made either through the "top" or
"bottom" of the furnace.

Propane Gas/High Altitude Installations

This furnace is shipped from the factory configured for natural
gas at standard altitude. Propane gas installations require an
orifice and spring change to compensate for the energy con-
tent difference between natural and propane gas.
High altitude installations may require both a pressure
switch and an orifice/spring change. These changes are
necessary to compensate for the natural reduction in the
density of both the gas fuel and the combustion air at
higher altitude.
Installation of this furnace at altitudes above 7000 ft (2134
m), shall be made in accordance with the Listed High Alti-
tude Conversion Kit available with this furnace.
For furnaces being converted to LP gas, it is strongly rec-
ommended that a LPLP03 kit also be installed. The use of
this kit will prevent the furnace from firing when the LP gas
supply pressure is too low to support proper combustion.
Contact the distributor for a tabular listing of appropriate
manufacturer's kits for propane gas and/or high altitude
installations. The indicated kits must be used to insure
safe and proper furnace operation. All conversions must
be performed by a qualified installer, or service agency.
