Heil Quaker ICP Z06G001 Switch

The Heil Quaker ICP Z06G001 Block Vent Switch is a critical safety component engineered for oil-fired heating appliances and high-efficiency furnace systems. Designed as a Blocked Vent Shutoff Switch (BVSO), this genuine OEM part monitors the exhaust flue for restricted airflow or backdraft conditions. If the venting system becomes obstructed by debris, ice, or seasonal nests, the Z06G001 switch detects the resulting pressure or temperature change to interrupt the limit control circuit, preventing the accumulation of hazardous carbon monoxide. This mechanical assembly is specifically optimized for systems operating under negative pressure and is compatible with a wide range of International Comfort Products brands, including Heil, Tempstar, Comfortmaker, and Arcoaire. Built for durability in industrial and residential settings, it features a rugged construction that withstands high-heat environments. For contractors, replacing a faulty vent switch with this exact ICP replacement part ensures the system meets original manufacturer specifications and safety standards during annual inspections or emergency service calls.

• OEM Compatibility: Specifically engineered for Heil, Quaker, Tempstar, and other ICP-branded oil furnaces and heating units.
• Safety Logic: Prevents furnace ignition if proper exhausting isn't confirmed, mitigating carbon monoxide risks.
• Versatile Mounting: Includes a heat transfer tube and fiber gasket designed for secure installation on the flue pipe.
• System Protection: Acts as a spill switch to detect flue gas spillage at the draft diverter or hood.
• Direct Fit: Replaces older ICP part numbers to maintain the integrity of the original furnace safety circuit.

What causes a block vent switch to trip?
A trip is typically caused by a restricted chimney, a collapsed flue liner, or severe downdrafts. It can also occur if professional-grade exhaust fans in the building create excessive negative pressure.

Is the Z06G001 switch manually reset?
Yes, many blocked vent shutoff switches require a manual reset. If the switch has tripped, the underlying venting obstruction must be identified and cleared by a technician before the system is restarted.

How do I verify if the switch is defective?
Technicians verify operation by checking for continuity across the terminals. If the switch is open while the venting is clear, or if there is 24V across the switch during a call for heat without ignition, the component may require replacement.
