EFC21 Control System For Gas

The EFC21 is a semi-automatic control with an integrated monitoring system that controls the exodraft chimney fan in connection with gas appliances. The control EFC21 was developed for gas fire places that are connected to an exodraft chimney fan.

The control monitors the failsafe function and if there is not sufficient chimney draft, the EFC21 stops the gas supply to the fireplace. This is to ensure that no gas enters the room.
