Installation with external ON/OFF
Example showing how a EFC21 controller can be connected directly to a gas fire without having to use an
extra SMG. This type of installation requires a fire with a controller that has flame-detection and automatic
ignition – or a permanent pilot light. If there is insufficient chimney draught (detected by the fan pressure
switch) the controller will switch off the gas fireplace (potential-free switch).
• Connect the mains earth to the earth terminal of the chimney fan.
• Connect the chimney fan and pressure switch to terminals 1–5.
• Optional external ON/OFF switch is connected to terminals 8–9.
• Connect the optional Air inlet monitoring to terminals 10–11.
If this monitoring is not mandatory then a jumper must be fitted across terminals 10–11.
• Connect start/activate burn control to terminals 12–13 (potential-free switch).
• Connect mains supply to terminals marked ”Supply”.
