LTERNATE ENT LUE OCATION
The alternate vent/flue location is the large hole directly in line with
the induced draft blower outlet. To use the alternate vent/flue loca-
tion on an upflow / horizontal model, refer to the following steps
and the "Alternate Vent/Flue Location" figure. To use an alternate
vent location on a counterflow / horizontal model, a special kit is
required.
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 screws from vent flange.
2. Remove internal elbow and vent pipe.
3. Cut pipe 2 1/2" from flange.
4. Remove cabinet plug adjacent to inducer outlet and install an
original cabinet vent hole.
5. Install RF000142 coupling on inducer outlet.
6. Install flanged vent section removed in step 2 & secure with clamps.
7. Secure flange to cabinet using screws removed in step 1.
