Utica-Dunkirk 2272156 Inducer Assembly, 120V, 3450 RPM
An OEM Utica-Dunkirk inducer assembly used in induced-draft boiler applications to establish proper draft and move combustion products through the venting system when the specified replacement assembly is required.
Key Features
- Inducer assembly rated 120V and 3450 RPM
- Includes: gasket and U-shaped metal plate
- Commonly paired with: Run Capacitor (12904-JARD)
Compatibility & Applications
- Listed as an Utica-Dunkirk inducer assembly
- Must only be used where the manufacturer specifies this exact part number: 2272156 (confirm by the boiler's model/serial and the unit's parts list).
Installation & Operation Notes
- Installation should be performed by a qualified boiler/HVAC service technician.
- Reference the boiler's installation/service manual and wiring/parts documentation for correct removal/installation and checkout.
- Properly supporting the vent pipe so the inducer does not carry the pipe's weight.
- Avoiding vibration transmission where the flue passes through the jacket (ensure clearance at jacket penetrations).
- Providing clearance at wall penetrations (manufacturer guidance cites roughly 1/8" to 1/4" clearance for expansion/contraction, with sealing as needed).
Maintenance & Troubleshooting
- As part of the draft/venting safety sequence, inducer service is commonly tied to no-heat conditions where draft cannot be established or the boiler will not run its normal sequence.
- Manufacturer guidance for inducer-related complaints highlights checking installation factors that can create unacceptable sound levels (vent support, flue/jacket contact, and penetration clearance) before assuming the inducer itself is the only cause.
- Follow the boiler's troubleshooting procedure to confirm the inducer is the root cause and verify safe operation after replacement.
User Reviews & Q&A Summary
- Correct-fit replacement: Multiple reviewers describe it as a direct replacement that bolted up and fit as expected, including induced-draft boiler applications (one reviewer references a Dunkirk XEB-4).
- Performance improvements: Some users report it being quieter than the old inducer and moving air effectively once installed.
- Included/extra hardware notes: Reviewers mention using the new plate included with the assembly; one reviewer noted they needed to source certain mounting screws separately.
- Substitution note: At least one reviewer reported receiving a different-brand inducer (identified as a Fasco unit) described as a direct substitution for part 2272156.
