All BCL 120 thru 250 models are provided with one blower prover switch with +0.38" w.c. setpoint. The blower prover switch is provided on the heater to verify that the fan is operating. It is a positive pressure switch whose electrical contacts are normally open. The blower prover switch electrical contacts will close on a rise in pressure as the blower increases the pressure in the burner. This switch is connected to the blower outlet pressure tap by a piece of silicone tubing. This tubing must be connected in order for the switch to close the electrical contacts.

Servicing should only be performed by a Qualified Service Technician
