Inducer Venting Conversion Instructions
Important: After deciding the orientation of the flue outlet, cut the
metal tabs around the appropriate 5” metal cutout on the
furnace cabinet and remove the cutout, if necessary.
Note: When rotating the inducer it may be necessary to cut the wire
tie. A new wire tie must be installed once the inducer is rotated.
Note: Self-tapping screws are recommended for attaching the vent
pipe to the inducer outlet.
Pressure Switch locations
L8V1 — The Pressure Transducer connects to the hot header.
Upflow orientation with top venting
Important: The combustion air duct MUST be installed on C100
upflow applications. Failure to install will result in
nuisance burner box limit trips.
Note: Future C100 furnaces with the Burner Box limit on the bottom
DO NOT require the Combustion Air Duct.
1. Install combustion air duct by sliding the split section of the duct
around the J-tube until it reaches the clearance hole of the duct.
2. Install hose clamp and hand tighten.
3. No changes need to be made to the inducer when installing the
furnace in upflow position when vented through the top.
Note: Self-tapping screws are recommended for attaching the vent
pipe to the inducer outlet.
Upflow orientation with left side venting
Important: The combustion air duct MUST be installed on C100
upflow applications. Failure to install will result in
nuisance burner box limit trips.
Note: Future C100 furnaces with the Burner Box limit on the bottom
DO NOT require the Combustion Air Duct.
Before proceeding, lay unit on its back to make the conversion easier.
The following changes need to be made to the inducer when installing
the furnace in upflow position with the combustion air vented out the
left side.
1. Remove the four screws holding the inducer in place.
2. Rotate the inducer so the inducer outlet is pointing towards the 5”
cutout.
3. Secure the inducer in place using the screws removed in step 1.
4. Attach the vent to the inducer outlet.
Note: Self-tapping screws are recommended for attaching the vent
pipe to the inducer outlet.
