Modine 3H0374540001 Pilot Assembly

Ensure reliable combustion in your Modine unit heaters with the Modine 3H0374540001 Pilot Assembly. Designed for professional intermittent pilot ignition (IPI) systems, this genuine OEM component is a direct replacement for obsolete part numbers including 3H37454-1, 3H37454-3, 5H0806900001, and 5H80690A0203. It is dual-fuel compatible, featuring orifices for both Natural Gas (NG) and Liquid Propane (LP), allowing for versatile application across various field configurations.

Built for the rigors of industrial and commercial heating, this Modine spark ignition pilot provides a stable spark for consistent main burner light-off. It is specifically engineered for high-performance units such as the PD250 gravity vented air heater and PA series models (PA105, PA130, PA175). The assembly includes the spark electrode, pilot hood, and required gas orifices to facilitate a streamlined swap on the job site. Using real OEM Modine replacement parts preserves the factory-certified safety and efficiency ratings of your HVAC equipment while preventing the nuisance lockouts common with generic alternatives.

• Precise OEM Fit: Drop-in Modine 3H0374540001 replacement ensures alignment with existing spark igniter mounting brackets.
• Dual Fuel Versatility: Includes both NG and LP pilot orifices for flexibility in different gas service environments.
• Reliable IPI Operation: Optimized for intermittent pilot ignition modules to reduce gas waste and improve cycle reliability.
• Robust Construction: Engineered to withstand high-temperature combustion zones without premature electrode degradation.

Is this compatible with standing pilot systems?
No, this is an intermittent pilot assembly designed for electronic ignition systems; it will not function with older standing pilot gas valves.

Does this assembly include the flame sensor?
This is the primary pilot and spark assembly. If your system requires a separate flame sensor (such as 5H0719450000), it must be ordered individually for a complete igniter assembly overhaul.

Will this work for both propane and natural gas?
Yes, the 3H0374540001 is a multi-fuel component. Ensure the correct orifice is installed to match the unit's fuel source during service.
