Antunes Controls 803113102 Pressure Switch

The Antunes Controls 803113102 is a heavy-duty LGP-H Low Gas Pressure Switch designed for precise monitoring of gas line pressures in commercial burner systems. This Manual Reset SPDT switch operates within a tunable 6-15 PSI range, ensuring the system shuts down safely if pressure drops below the required set point. It features a rugged die-cast aluminum housing and a 1/4 inch NPT connection for the primary gas line, along with a 1/8 inch NPT vent. Engineered for industrial furnace safety and boiler applications, the 803113102 provides reliable electrical interlocking for HVAC gas pressure monitoring. The manual reset mechanism requires technician intervention after a trip, facilitating necessary diagnostics before restarting the equipment. This Antunes gas safety switch is a standard component for contractors maintaining compliance with strict combustion safety protocols.

Key Benefits:

• Field-Adjustable Set Point: Fine-tune pressure thresholds between 6 and 15 PSI to meet specific equipment requirements.
• Manual Reset Security: Prevents automatic cycling of the system after a low-pressure event, ensuring technician inspection.
• SPDT Switch Configuration: Offers versatile wiring options for normally open or normally closed circuits in safety loops.
• Durable Construction: Built with high-quality materials to withstand the vibration and temperature fluctuations of mechanical rooms.
• Standard Fittings: Utilizes 1/4" NPT process connections for seamless integration into existing gas manifolds.

Common Questions:

How do I adjust the pressure setting on the 803113102?
Remove the top cover and turn the adjustment screw to align the internal scale with your required PSI set point; always verify the trip point with a calibrated manometer.

Can this switch be used for high-pressure cutout applications?
No, this model is specifically an LGP-H Low Gas Pressure Switch; for high-pressure protection, a dedicated HGP model must be utilized.

Does this unit require a vent line?
Yes, the 1/8" NPT vent port should be piped to a safe outdoor location or an approved atmospheric vent in accordance with local mechanical codes.
