Burnham Boiler 80160751 Pressure Switch

The Burnham 80160751 Pressure Switch is a critical safety component designed for precise draft monitoring in specific Burnham Alpine and Series 2 boiler models. Engineered with a factory-set 0.60" WC (Water Column) trip point, this SPST (Single Pole Single Throw) switch ensures the inducer motor is moving sufficient combustion air before allowing the ignition sequence to proceed. It features a standard 1/4" barb connection for secure pneumatic tubing attachment and facilitates reliable electrical continuity under demanding thermal cycles. For field technicians, this direct replacement pressure switch ensures the heating system maintains its AFUE rating and operational safety margins without the drift often associated with universal aftermarket alternatives.

Key Technical Benefits

• OEM Compatibility: Specifically calibrated for Burnham boiler parts integration to prevent nuisance lockouts.
• High-Precision Sensing: Fixed 0.60" WC differential ensures accurate response to flue pressure changes.
• Industrial Build: Durable diaphragm construction resists fatigue in condensing gas boiler environments.
• Rapid Installation: Features standard spade terminals and a 1/4 inch barb for immediate drop-in replacement.

Common Contractor Questions

What causes a pressure switch lockout on a Burnham boiler?
Beyond a faulty switch, lockouts often stem from a restricted vent pipe, a failing inducer motor, or moisture in the sensing lines. If the Burnham 80160751 fails to close, verify the venting system is clear before replacing the component.

Can I use an adjustable pressure switch to replace the 80160751?
It is not recommended. The 0.60" WC setpoint is engineered for the specific blower curve of the appliance; using a non-OEM specification can lead to incomplete combustion or safety hazards.

How do I test this SPST pressure switch?
Using a manometer and a multimeter, apply the rated 0.60" WC pressure to the barb and check for continuity across the terminals. If the resistance is high or the circuit remains open, the switch requires replacement.
