This pilot-operated valve requires a minimum pressure differential of 5 PSI to function correctly and ensure the diaphragm lifts
preventing hazardous operation in the event of flue blockages or inducer assembly failure
The Maxitrol 325-9L-2-12A49 is a field-proven 2-inch NPT line pressure gas regulator designed for high-capacity residential and commercial 2 PSI piping systems
Always verify your specific wiring diagram to ensure the fan timer control board matches your system's CFM requirements for both stages

ICM Controls ICM104 Relay 318172-701 This pilot-operated valve requires aThe ICM Controls ICM104 Delay On Make Timer is an adjustable HVAC R time delay relay designed for applications requiring controlled equipment startup. Operating at 1830 VAC, 50 60 Hz, the ICM104 provides an adjustable 101,000 second time delay. When input power is applied, the timing cycle begins. Once the selected delay expires, the load energizes. The control uses precise digital circuitry with an isolated, high power SPDT (1 Form C) relay output.
