air duct connections on either side or the furnace bottom.
When airflow requirements are greater than 1,800 CFM for
heating or cooling, both sides or a bottom return must be
used.
Down flow furnaces installed vertically must have the re-
turn duct connection on top the furnace. For any furnace
installed horizontally, return duct must be attached to the
end of the furnace.

This furnace is shipped from the factory configured for natural
gas up to 10,000 ft. altitude. Propane conversions require
the proper LP kit to compensate for the energy content dif-
ference between natural and propane gas.
LP kits include an L.P. gas valve and a set of gas orifices.
Although the gas valve is ready to use with L.P. gas, be
sure not to remove the tape from the regulator screws. Do
not change or adjust the gas valve regulator springs.

ROPER ENT LUE AND OMBUSTION
Adhere to these instructions to ensure safe and proper furnace
performance. The length, diameter, and number of elbows of
the vent/flue pipe and combustion air pipe (when applicable)
affects the performance of the furnace and must be carefully
sized. All piping must be installed in accordance with local codes
and the insttaltion manual shipped with the furnace.
Piping must be adequately secured and supported to prohibit
sagging, joint separation, and/or detachment from the fur-
nace. Horizontal runs of vent/flue piping must be supported
every three to five feet and must maintain a 1/4 inch per foot
downward slope, back towards the furnace, to properly return
condensate to the furnace's drain system.
