Heil Quaker ICP 1149021 Gas Valve

Protect your heating system's reliability with this genuine Heil Quaker ICP 1149021 Gas Valve. Engineered for Natural Gas applications, this 24V 3/4" NPT valve features a step-opening characteristic, typically starting at 0.7" W.C. before reaching the factory-set 3.5" W.C. main burner pressure. This sequenced operation ensures a smooth, safe ignition cycle, reducing burner roar and minimizing mechanical stress on the heat exchanger. Specifically designed for intermittent pilot systems, it serves as a direct OEM replacement gas valve for various ICP, Heil, and Tempstar furnaces.

As a single-stage HVAC gas valve, the 1149021 is built to withstand rigorous high-cycle demands in both residential and light commercial settings. The valve includes high-capacity 3/4" x 3/4" inlet and outlet ports and is often supplied with reducing bushings for systems requiring 1/2" connections. For technicians diagnosing ignition failures, ensure 24V is present at the solenoid terminals during the trial for ignition; if the intermittent pilot gas valve fails to click or "thump" while energized, a mechanical internal failure is likely. This robust control integrates seamlessly with original Honeywell VR8304P series specifications, maintaining the precise pressure regulation required for Natural Gas furnace peak performance.

• Step-Opening Ignition: Facilitates a controlled, quieter start-up by delivering a low initial pressure before stepping up to full manifold pressure.
• OEM Precision: Guaranteed compatibility with Heil Quaker and ICP equipment, eliminating the mounting and wiring headaches of "universal" kits.
• High Flow Capacity: Rated for 30 to 415 CFH, providing the volume necessary for large BTU furnace and boiler applications.
• Standardized Connections: 3/4" threading with included bushings allows for versatile HVAC part installation across varying manifold sizes.

What is the purpose of a "step-open" gas valve?
A step-open valve is designed to prevent "delayed ignition" by providing a small amount of gas initially to establish a flame before opening fully, ensuring a smoother transition to high fire.

Can this natural gas valve be converted to LP (Liquid Propane)?
While many intermittent pilot valves can be converted using a specific manufacturer's conversion kit, this unit is factory-configured for Natural Gas ONLY at 3.5" W.C.

Will this valve replace a Honeywell VR8304P model?
Yes, the ICP 1149021 is the specific manufacturer part number for the VR8304P4306, making it the correct technical match for those specs.
