FAN PROVER SWITCH
OWNERS INSTRUCTIONS
THESE MUST REMAIN WITH EQUIPMENT
DO NOT DESTROY
PURPOSE
The Tjernlund Fan Prover has been designed to monitor the pressure
within the fan housing only. A motor or wheel failure will decrease hous-
ing pressure and deactivate the pressure switch, thus preventing combus-
tion. The 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 both 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 pro-
cedures may result in generation of toxic carbon monoxide gas.
