5. Remove plastic plug from alternate vent/flue location.
Relocate and install plug in standard vent/flue location (top
cover).
6. Insert cut section of vent/flue pipe and coupling into alternate
vent/flue location. Using a rubber coupling and worm gear
hose clamps from the drain kit bag, attach the vent/flue pipe
and coupling to the induced draft blower. Secure the
coupling to the cabinet using the screws removed in step 1
or with field-supplied 3/8" #8 self drilling screws.
T
HE RUBBER ELBOW IS NOT DESIGNED TO SUPPORAT A LOAD.
RUBBER ELBOW IS MOUNTED EXTERNALLY TO THE FURNACE CABINET,
EXTREME CARE MUST BE TAKEN TO ADEQUATELY SUPPORT FIELD-SUPPLIED
VENT/FLUE PIPING, AS DAMAGE CAN RESULT IN LEAKS CAUSING BODILY
INJURY OR DEATH DUE TO EXPOSURE TO FLUE GASES, INCLUDING CARBON
MONOXIDE.
7. For upright installations, externally mount the rubber elbow
to the vent/flue coupling using a worm gear hose clamp.
Secure field supplied vent/flue piping to the rubber elbow
using a worm gear hose clamp. NOTE: Use of the alternate
vent/flue location for upright installations, requires the drain
trap be installed on the same side of the unit as the flue
pipe.
8. For horizontal installations, externally secure the field-
supplied vent/flue pipe directly to the vent/flue coupling using
a PVC or ABS coupling or elbow.

Non-direct vent installations require only a vent/flue pipe. The vent
pipe can be run horizontally with an exit through the side of the
building or run vertically with an exit through the roof of the building.
The vent can also be run through an existing unused chimney;
however, it must extend a minimum of 12 inches above the top of
the chimney. The space between the vent pipe and the chimney
must be closed with a weather-tight, corrosion-resistant flashing.
For details concerning connection of the vent/flue pipe to the fur-
nace, refer to Section IX, Vent/Flue Pipe and Combustion Air -
Standard Furnace Connections or Alternate Furnace Connections
for specific details. Refer to the following Non-Direct Vent (Single
Pipe) Piping - Vent/Flue Pipe Terminations for specific details on
termination construction.
Although non-direct vent installations do not require a combustion
air intake pipe, a minimum of one 90° elbow should be attached to
the furnace's combustion air intake if: an upright installation uses
the standard intake location. This elbow will guard against inad-
vertent blockage of the air intake.

ENT LUE IPE ENGTHS AND
Refer to the following table for applicable length, elbows, and pipe
diameter for construction of the vent/flue pipe system of a non-
direct vent installation. In addition to the vent/flue pipe, a single 90°
elbow should be secured to the combustion air intake to prevent
inadvertent blockage. The tee used in the vent/flue termination
must be included when determining the number of elbows in the
piping system.
