on irect ent nstallations
A minimum of one 90° elbow should be installed on the combus-
tion air intake "coupling" to guard against inadvertent blockage.
Alternate Vent/Flue Location
On upflow models, the alternate vent/flue location is the large
hole directly in line with the induced draft blower outlet. To
use the alternate vent/flue location refer to the following
steps and the "Alternate Vent/Flue Location" figure.
NOTE: In the horizontal left installation position, a means
of condensate collection must be provided to keep vent
pipe condensate from entering the draft inducer housing.
If the vent drain elbow is eliminated from the installation,
an RF000142 kit must be used.
1. Remove the four screws from the vent pipe flange on
top the furnace.
2. Remove the internal elbow and vent pipe
3. Cut 2 1/2" from the flange .
4. Remove plastic plug in line with the inducer outlet
5. Install cut end of the flanged section and connect to
inducer with rubber coupling supplied with furnace.
6. Install screws removed in step 1 securing flange to
cabinet.
Insert flange. Cut 2 ½" long.

1. Maximum allowable limits listed on individual lengths for inlet and
flue and NOT a combination.
2. Minimum requirement for each vent pipe if five (5) feet in length
and one elbow/tee.
3. Tee used in the vent/flue termination must be included when de-
termining the number of elbows in the piping system.
4. 2 1/2" or 3" diameter pipe can be used in place of 2" diameter
pipe.
