The PS1505 Fan Prover has been designed to monitor the pressure within the fan housing only. A motor or wheel failure will decrease housing pressure and deactivate the pressure switch thus preventing combustion.

The PS1505 Fan Prover is not a safety control designed to ensure proper draft or to indicate chimney failure. It is the responsibility of the end user to properly maintain the combustion equipment and its chimney or vent. Yearly maintenance and inspection should be conducted by qualified service personnel. Failure to follow such maintenance and inspection procedures may result in generation of toxic carbon monoxide gas.
