Description
The Utica-Dunkirk 1500009 is a 280°F Blocked Vent Safety Switch engineered to protect residential and light-commercial heating systems from the hazards associated with blocked or restricted flue venting. When vent temperatures rise to unsafe levels due to an obstruction, this safety switch responds by shutting down the burner, preventing heat exchanger damage, carbon monoxide buildup, and potential fire hazards.
Key Features
- 280°F trip temperature provides reliable, precise overheat detection
- Designed specifically for Utica-Dunkirk boilers and heating equipment
- Blocks burner operation upon detecting dangerous blocked-vent conditions
- Direct OEM replacement ensures proper fit and reliable performance
- Helps protect against carbon monoxide risks associated with flue blockages
- Supports safe, code-compliant system operation
Why Blocked Vent Safety Switches Matter
A blocked vent safety switch is a critical safety component in any gas-fired heating system. If the flue becomes obstructed by debris, ice, or a bird’s nest, combustion gases can back up into the living space — creating a serious carbon monoxide hazard. The Utica-Dunkirk 1500009 monitors vent temperatures and automatically shuts down the appliance before conditions become dangerous, giving homeowners and technicians peace of mind.

- Compatible with select Utica-Dunkirk boilers and heating appliances
- Ideal for use as a direct OEM replacement part
