Heil Quaker ICP 1170429 Gas Valve

The Heil Quaker ICP 1170429 Gas Valve is a critical direct replacement component designed for high-efficiency furnace ignition systems. This Honeywell SmartValve assembly integrates the gas control and electronic ignition functions into a single unit, specifically engineered for ICP-branded HVAC equipment, including Heil, Tempstar, and Comfortmaker. Operating on a 24V signal, this natural gas valve regulates fuel flow while providing precise sequence timing for the intermittent pilot system. It features a compact footprint suited for tight furnace vestibules and includes standard 1/2-inch NPT inlet and outlet connections for seamless mechanical integration.

Technicians rely on the 1170429 gas control for its reliable solenoid operation and internal pressure regulation. When troubleshooting pilot outages or main burner ignition failures, this valve serves as the central diagnostic point. It is built to maintain stable manifold pressure, ensuring consistent combustion performance across varying input conditions. Professionals should verify the specific SV9501 series model number on the existing valve to ensure electrical harness compatibility during installation.

Technical Specifications & Field Benefits

Common Contractor Questions

Is this valve compatible with LP (Propane) systems?
This unit is factory-configured for natural gas. For LP applications, a specific conversion kit must be installed to adjust the orifice and regulator spring settings.

Does this replace older SV9500 series valves?
The 1170429 replaces specific SmartValve generations. Always verify the wiring harness pin configuration as some older iterations require an adapter or lead modification.

What is the typical cause of failure for this component?
Failures often manifest as a failure to initiate the pilot spark or a stuck solenoid coil. Ensure the 24V transformer is providing adequate VA before replacing the valve assembly.
