It's easy to install the Tjernlund Fan Proving Switch. This unit will give you one additional step of safety in your venting system. This device monitors the fan housing only.

Features:

  • Monitors PSI in fan housing
  • Can be mounted on any vertical surface
  • Includes mounting hardware
  • Fixed set point
  • Prevents combustion in fan housing

The Tjernlund Fan Proving Switch is designed to accurately monitor the fan housing only. A motor or wheel failure dramatically lowers the housing pressure and deactivates the pressure switch to safely prevent combustion within the fan housing.

This fan proper does not ensure proper draft, nor will it indicate any chimney failure. This device only monitors the fan housing. Yearly maintenance and inspection of chimney systems should be regularly scheduled by the home owner.
