Recommended Installation Positions
*MEC96 models may be installed upflow or horizontally with
left or right side down. *CEC96 models may be installed down
flow or horizontally with left or right side down. Do not install
this furnace on its back. For upright upflow furnaces, return
air ductwork may be attached to the side panel(s) and/or
basepan. For horizontal upflow furnaces, return air ductwork
must be attached to the basepan. For both upright or hori-
zontal counterflow furnaces, return ductwork must be at-
tached to the basepan (top end of the blower compartment).
NOTE: Ductwork must never be attached to the back of the
furnace. Refer to "Recommended Installation Positions" figure
for appropriate installation positions, ductwork connections,
and resulting airflow arrangements.

ORIZONTAL PPLICATIONS
When installing a furnace horizontally, additional consideration
must be given to the following:

URNACE USPENSION
If suspending the furnace from rafters or joists, use 3/8" threaded
rod and 2"x2"x1/8" angle iron as shown in the following dia-
gram. The length of rod will depend on the application and the
clearances necessary.
If the furnace is installed in a crawl space it must be suspended
from the floor joist or supported by a concrete pad. Never install
the furnace on the ground or allow it to be exposed to water.
