1. Product information
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).

2. Installation
All installations must be carried out by competent personnel in
accordance with local laws and regulations.
Isolation switch • An isolation switch must be installed between the controller and
the chimney fan.
• For installation of the isolation switch please consult the
installation instructions for the chimney fan.
• The isolation switch is not supplied by EXHAUSTO.
The control panel is to be installed on a level surface with a minimum distance of 100
mm to any corner.
The front cover is removed from the frame by twisting a screw driver in the two holes on
the sides of the front cover. The front cover can then be tipped carefully and the frame
can be mounted on the wall.
Notice The front cover is mounted with a connection ribbon cable in the right side, which results
in a restricted opening of this side.
The assembling part of the IR-sensor, the black cable, may not be bend.
The control box covers a standard single back box.(Not EXHAUSTO supply)
.
• Installation of the power supply wire must be carried out in
accordance with local laws and regulations.
• The earth wires must always be connected.
• Before the appliance a fused switch must be present that
completely disables power to the appliance. The switch must
always be switched off when the appliance is not in use.

Description The example shows how to connect the EFC25 directly to the fireplace control. This
installation demands a fire with a control unit which has flame detection and automatic
ignition. In case of insufficient flue gas flow (controlled by the PDS in the fan) the
fireplace control will be disconnected, by means of a voltage free contact.
• Connect the earth wires between power supply and chimney fan
• Connect the chimney fan and pressure switch to terminals 1-5
• Connect the start/release signal for the burner control to terminals 12-13 (voltage
free contact)
• Connect Step 2 signal (if any) to terminals 14-15 (voltage free contact)
• Connect the power supply to the terminals marked ”Power”.

3. Commissioning
Commissioning is carried out with the control panel open. Only touch
the components in the box with electrically insulated tools.
Notice Before commissioning all windows and doors must be closed; if other types of fans are
installed they must be switched on 10 minutes in advance and run at full speed during
commissioning.
Dipswitches Check the factory settings of the dipswitches (Fig. 1-I) before commissioning.
In service mode the safety functions of the flow control (PDS) and the
fresh air inlet are bypassed
• Open control panel
• Press ON/OFF button (Fig. 1-C)
• Wait until constant green light, if the fire has to be lit during commissioning
• Press the service mode button (Fig. 1-H) on reverse of front cover. The alarm
LED (Fig. 1-A will flash RED and operation LED (Fig. 1-B) will flash according to
the position of the PDS switch as follows:

• The potentiometer (Fig. 1-J) is set at maximum by turning clockwise.
• Adjust the speed slowly down by using the potentiometer. Check for spillage by
carrying out a thorough test, all along the edge of the fireplace.
• If spillage is detected, increase the fan speed until spillage cannot be detected.
• If the control unit Step 2 is connected to the gas fire unit, high level can be
activated from the remote control (Fig. 2-C)
The pressure switch is typically placed inside the chimney fan.
• Set the PDS at minimum by turning anti-clockwise. Minimum is 20 Pa, do not
attempt to turn the dial lower than 20 Pa
• Increase slowly the PDS setting until disengagement of the PDS can be
registered (click sound) or the operation LED changes from GREEN to RED.
• Register the PDS value of disengagement.
• Turn back the setting of the PDS until it is connected, the operation LED changes
to GREEN.
• Set the PDS to 10 Pa below the registered value of disengagement.
• Press the ON/OFF button (Fig. 1-C) and the control turns off the service mode.
• Check the start-up function after commissioning by pressing the ON/OFF button
to start the fireplace
• Check the fireplace for spillage with all windows and doors closed; if other types
of fans are installed they must be switched on and running at full speed.
• If spillage is detected, repeat commissioning.
• After 10 minutes without spillage switch off the isolation switch for the chimney
fan and check the fail-safe function. The fireplace must cut-out 15 seconds after
the PDS has disconnected. Remember to turn the isolation switch back on.
• Mount the front cover
• Inform the end-user about the functions of the control and leave the instructions
with the end-user.
• Keep one copy with the appliance
• Post one copy back to EXHAUSTO Ltd. (pre-paid)
