Contractors Only

Some Effikal brand vent dampers (involving all sizes) that were manufactured between July 1, 2007 and March 1, 2008 have developed cracks on the plastic ears connecting the motor assembly to the mounting bracket. If both ears break, the motor assembly could disconnect from the bracket. If this occurs, the boiler may light with the vent damper in the closed or partially closed position.

Vent Damper Replacement Procedure:

  1. Purchase replacement motor assemblies, Effikal Part #70009000, for $25 from the wholesaler.
  2. Replace vent damper motor assemblies of all vent dampers in the
