1.1 EFC 25 Control System for EXHAUSTO Chimney Fans

Applications The EXHAUSTO fireplace control EFC 25 (Fig. 1) has been developed for use with gas

fire control units which have flame detection and automatic ignition, and in connection
with the installation of EXHAUSTO chimney fans.

The control system supervises the fail-safe function. In case of insufficient chimney
draught, the EFC 25 will shut down the fireplace.

The control system is developed to meet BS 5440: Part 1(2000), BS 6644(1991), Gas
Appliance Directive 90/396/EEC, EN 298(1993) and other relevant European standards.

Functions By activating the EFC 25, the chimney fan will immediately start up on full speed. When

the fail-safe supervision confirms sufficient chimney draught, the fireplace will be lit and
the fan speed will adjust to the pre-set value corresponding to the appliance operating
normally, (Fig. 1-J).

The control has a step-up function and a 15-second built-in delay function to avoid
nuisance cut-outs.

By using the remote control (Fig. 2) it is possible to switch between high and low fire.

When EFC 25 is turned off, the chimney fan stops. It is possible to pre-set a run-on time
period of 3 minutes, (Fig. 1-I).

The EFC 25 and RSVG can also be used for venting purposes.

Fail-safe settings. The fail-safe settings can be set by dipswitches (Fig. 1-I) according to local laws and

standards.

• RESET after fail-safe lock-out (manual/automatic).
