MODEL PS1505 FAN PROVING SWITCH SAFETY INTERLOCK The Model PS1505 Fan Proving Switch works on all Tjernlund Draft Inducers to assure adequate draft is present before burner is allowed to fire. The PS1505 complies with burner safety interlock provisions of National Mechanical Codes. PURPOSE 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.

TYPICAL INSTALLATION ELECTRICAL WIRING Wiring diagrams are included in these instructions for various draft inducer applications. While it would be impractical to show every conceivable variation, the ones included will demonstrate sufficient basic techniques for the design and installation of the unusual control system. The installer should always check the rated capacity of a burner primary control.
