ENERAL RAIN NFORMATION
All furnace models come with a factory installed drain trap. For
vertical installations, the trap will remain in the factory posi-
tion. All furnace models installed horizontally require the trap to
be relocated. Many drain hoses have a built–in grommet which
will provide a cabinet seal when installed. See instructions below
for your model and installation position. NOTE: Both sides of
the drain trap must be primed prior to initial furnace start
up

IELD UPPLIED RAIN
Drain the furnace and air conditioning coil if applicable, in com-
pliance with code requirements. In horizontal installations, a field
installed rubber coupling will allow the drain trap to be removed
for cleaning. The drain trap must be primed before initial fur-
nace start up. When an air conditioning coil drain is connected
to the field supplied furnace drain, it must be vented with an
open tee installed at a height no higher than the bottom of the
furnace collector box to prevent air conditioning condensate from
backing up into the furnace if the common drain became blocked.
