NOTE: Standard and alternate locations can be combined (for 
example, an installation may use the standard combustion air 
intake location but use the alternate vent/flue location or vice 
versa), if needed.

Alternate Vent/Flue Location

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” illustration.

NOTE: Counterflow instructions follow the upflow instructions.

Upflow Units

1. Remove and save the 4 screws securing the vent/flue 

coupling to the furnace top panel.

Counterflow Units

Remove and save the 4 screws securing the vent/flue 
coupling to the furnace base pan. Also remove the 3 screws 
securing the furnace’s internal vent/flue piping to the blower 
deck.

Upflow and Counterflow Units

2. Loosen the worm gear hose clamps on the rubber elbow and 

detach the rubber elbow from both the induced draft blower 
and the vent/flue pipe.

3. Remove the vent/flue pipe from the furnace.

Upflow Units

4. Cut the vent/flue pipe 3

³⁄₄

" (9.5 cm) from the flanged end of 

the pipe. See “Vent/Flue Pipe Cuts” illustration. 

NOTE: The section of pipe attached to the coupling will reach 
through the side panel to the induced draft blower. 

5. Discard remaining pipe and elbows.

Save vent/flue pipe attached to the blower deck coupling for 
use in the alternate location.

Discard remaining pipe and elbows.

6. Remove the plastic plug from the alternate vent/flue location.

7. Relocate and install the plastic plug in the standard vent/flue 

location (top cover).

Counterflow Units

Remove the plastic plug from the alternate vent/flue location.

Relocate and install the plastic plug in the standard vent/flue 
location (base pan). 

Plug remaining hole in the blower deck with the plastic plug 
included in the drain kit bag.

Upflow and Counterflow Units

8. Insert the cut section of the vent/flue pipe and coupling into 

the alternate vent/flue location. 

9. Attach the vent/flue pipe and coupling to the induced draft 

blower using a rubber coupling and worm gear hose clamps 
provided in the drain kit bag. 

10. Secure the coupling to the cabinet using the screws removed 

in Step 1 or with field-supplied 

³⁄₈

" #8 self-drilling screws.

11. For upright installations, externally mount the rubber elbow to 

the vent/flue coupling using a worm gear hose clamp.

12. Secure the 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 to be installed on the 
same side of the furnace as the flue pipe.

13. 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.

Placeholder

The rubber elbow is not designed to support a load. 
When the 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.
