Description
The Laars Heating Systems R2061500 Pressure Switch Kit 2.30″WC is a control and safety component used in gas-fired boiler systems to monitor air or flue pressure during operation. It responds to a calibrated pressure threshold water column, ensuring that the inducer fan and venting system are operating correctly before allowing ignition. In HVAC system equipment it is installed in heating units to check proper airflow through the combustion chamber and exhaust path avoiding unsafe operation under blocked or insufficient draft conditions. The switch integrates into the control circuit to permit or interrupt system start-up based on pressure output, supporting safe combustion and accurate heating performance.
