Heil Quaker ICP 1005597 Gas Valve

The Heil Quaker ICP 1005597 Gas Valve is an OEM-spec replacement engineered for residential and light commercial natural gas furnaces. This intermittent pilot gas valve features a 1/2-inch NPT inlet and outlet, designed for precise fuel flow regulation in ICP-manufactured equipment, including brands like Comfortmaker, Tempstar, and Arcoaire. Designed for reliability in harsh environments, it is rated for a low-temperature ambient operation down to -40°F, ensuring the solenoid coils and internal diaphragms function without sticking during extreme cold snaps. The gas valve manifold pressure is factory-set to a standard 3.5" W.C., facilitating straightforward installation and combustion analysis for field technicians. Whether you are performing a furnace gas valve replacement or troubleshooting ignition failures, this high-quality Honeywell or White-Rodgers equivalent part provides the consistent millivolt signal response required by the integrated furnace control board to maintain safe and efficient burner operation.

• OEM Compatibility: Precision-fit for Heil, Quaker, and ICP units, reducing "truck stock" guesswork and ensuring proper furnace part replacement.
• Extreme Weather Resistance: Rated for -40°F to +175°F, preventing mechanical failure or sluggish response in unconditioned spaces.
• Standardized Porting: Features a 1/2" NPT connection and standard terminal wiring for fast retrofit and HVAC gas valve installation.
• Regulated Performance: Pre-set 3.5" W.C. ensures optimal BTuh output and efficient combustion across the heat exchanger.

Is the ICP 1005597 compatible with LP (Propane) systems?
This valve is factory-configured for Natural Gas at 3.5" W.C. To use this in an LP furnace conversion, a specific manufacturer-approved conversion kit must be installed to adjust the spring and orifice settings.

What are the symptoms of a failing furnace gas valve?
Common indicators include the burner failing to ignite despite a confirmed spark or hot surface igniter glow, "chattering" solenoid noises, or inconsistent manifold pressure readings during a manometer test.

Can I use this gas valve in any furnace brand?
While the 1/2" NPT threading is standard, gas valves are safety-critical components. This part is specifically calibrated for ICP equipment architectures; verify your specific model number against the OEM cross-reference list before installation.
