Heil Quaker ICP 1013351 Gas Valve

The Heil Quaker ICP 1013351 Gas Valve is an OEM-grade SV9541Q SmartValve system control engineered for high-efficiency, 2-stage gas valve applications. This intermittent pilot control integrates a pressure regulator, electronic sequencing, and safety shut-off into a single heavy-duty unit, making it a critical component for ICP (International Comfort Products) equipment including C8MPT, C8MPV, C9MPT, and C9MPV series furnaces. Designed for versatility, this dual fuel gas valve is factory-configured for natural gas but is fully compatible with liquid propane (LP) conversions when using the appropriate Honeywell conversion kit. Technical professionals will appreciate its 1/2" NPT inlet and outlet ports, 24 Vac electrical rating, and the integrated SmartValve technology that coordinates directly with the Q3450 or Q3480 pilot hardware. Whether diagnosing a failing solenoid or optimizing manifold pressure during a seasonal tune-up, the 1013351 replacement part provides the precision required for stable combustion and reliable ignition sequencing in fan-assisted heating systems.

• 2-Stage Operation: Provides precise low and high-fire regulation for improved thermal comfort and equipment efficiency.
• OEM Compatibility: Specifically designed for ICP families including Heil, Quaker, Tempstar, and Comfortmaker furnaces.
• Integrated Sequencing: Combines gas flow control with electronic intermittent pilot logic to streamline troubleshooting.
• SmartValve Technology: Interfaces seamlessly with fan timers and power-stealing thermostats for advanced system communication.
• Dual Fuel Support: Robust internal diaphragms support both Nat and LP gas systems with field-installed conversion kits.

How do I confirm if my SV9541Q is failing?
Technicians should check for 24 Vac at the valve terminals when the inducer is running and the pressure switch is closed. If voltage is present but the valve fails to click or open, or if you observe 0.0" WC manifold pressure with gas supplied, the internal solenoid or sequencing circuit has likely failed.

Can this 1013351 valve be used with LP gas?
Yes, but it must be field-converted. Do not attempt to use a natural gas-set valve on LP without installing the specific Honeywell LP conversion kit (typically including a spring and cap screw) and adjusting the regulator to the manufacturer-specified 10.0" - 11.0" WC.

Does this valve support post-purge cycles?
The post-purge function is factory-set but is typically only available when the control is interfaced via an electronic fan timer; if wired directly to a thermostat, power is removed at the end of the call for heat, ending the purge immediately.
