Downflow Installation
When the furnace is installed in the downflow position
the combustion air and exhaust vent may exit through
the left or right side of the cabinet (when viewed in the
upflow position.). The inducer is installed so that the left
side exits require no rotation.
If exhaust vent exits the left-side panel the pipe can be
routed straight outside the cabinet.
If exhaust vent exists the right-side panel the
inducer requires rotation.
The pipe exiting the cabinet in any installation should be
long enough to install the vent clamp on the outside of
the cabinet.
WARNING
WHEN INSTALLED IN THE DOWNFLOW POSITION ON A
COMBUSTIBLE FLOOR, SUBBASE KIT #30476 IS
REQUIRED. FAILURE TO INSTALL SUBBASE KIT COULD
RESULT IN FIRE, DEATH OR SERIOUS INJURY.
The opening in the floor must provide adequate clearances
to the combustible material.
A half-inch of clearance will be required between the
plenum and the combustible material. If installed on a
non-combustible material, zero clearance is required.
In the downflow installation, this furnace can only vent
through the left or right side of the furnace.
The condensate drain trap can be mounted on the right or
left side.
