Laars Heating Systems R2004100 Pressure Switch
Maintain the industrial safety standards of your heating equipment with the Laars Heating Systems R2004100 Pressure Switch. This manual reset low gas pressure switch is a critical safety component designed for high-output Laars commercial boilers and MagnaTherm water heaters. Engineered to detect hazardous drops in fuel pressure, the R2004100 interrupts the system's ignition cycle to prevent incomplete combustion and potential carbon monoxide buildup. As a genuine OEM HVAC replacement part, it ensures precise calibration and seamless integration with the gas train assembly, specifically for RHCH, RHCV, and RHHH series models. Its robust construction is built to withstand the rigorous demands of commercial mechanical rooms, providing reliable performance in HVAC gas pressure monitoring. The manual reset feature requires a technician's inspection before the system can resume operation, ensuring that the underlying cause of the pressure drop is addressed for long-term operational integrity.
Key Benefits- System Protection: Actively monitors for low gas pressure conditions to prevent equipment damage and safety hazards.
- OEM Compatibility: Exact replacement for Laars boiler parts, including MagnaTherm 1600 through 4000 MBTU/h units.
- Rigid Safety Standards: Features a manual reset mechanism to force inspection after a safety trip.
- High Durability: Engineered for industrial-grade HVACR pressure control in high-demand environments.
- Precise Calibration: Factory-set to ensure accurate sensing within the Laars gas train assembly.
What models are compatible with the R2004100?
This switch is designed for use with Laars MagnaTherm and RHCH/RHCV series boilers, including 1200, 1600, 2000, and up to 4000 MBTU units.
Why is my low gas pressure switch tripping?
Trips are typically caused by a drop in incoming gas supply pressure or a restriction in the gas line. Since this is a manual reset switch, the system must be inspected by a professional before restarting.
Can I use a universal pressure switch instead of the R2004100?
For boiler safety components, using the specific Laars OEM pressure switch is critical to maintain the engineered safety parameters and correct electrical interface of the control board.
