Description
The Burnham Boiler 80160744 Pressure Switch is a fixed-setting air pressure safety switch used in boiler systems to verify proper draft, and combustion air flow before allowing burner operation. It is calibrated to a precise switching point of 0.80 inches water column, ensuring the inducer fan is generating sufficient negative pressure for safe ignition and continued firing. Installed in a gas-fired system, it connects to the vent or combustion air tubing and signals the control system when airflow conditions are within safe limits. This helps prevent unsafe burner startup, protects against flue blockages, and ensures accurate combustion performance in the heating applications.
