Place Furnace in Final Location
IMPORTANT: Place the furnace in the final location and position
it in the proper orientation to the house so that connecting ducts,
electrical and gas supplies is easily done. Hoisting may be
required.
Hoisting
NOTE: All access panels must be secured in place before
hoisting.
The unit should be hoisted with 2 lifting slings. Attach the slings
to rigging shackles that have been hooked through holes in the
base rail.
Place 2 spreaders on top of the unit to protect the unit from
damage from the pressure exerted by the slings. Make sure that
all equipment is rated to handle at least 750 lbs and that the
slings will not allow the unit to shift. See “Typical Sling
Configuration.”
Typical Sling Configuration
Convert to Downflow
This furnace is factory built for horizontal airflow applications and
may also be field converted for downflow use.
To convert to downflow use:

panel.
2. Remove the 2 downflow duct cover plates (2 screws) found in
the return and supply air compartments.
3. Using the 2 screws from each duct cover plate, and the 8
screws in the provided literature bag, install the previously
removed duct cover plates on the horizontal return and
supply air openings.
4. Reinstall blower access panel and heat exchanger access
panel.
