Standard installation
The diagram shows how a separate solenoid valve (SMG) must be connected to the EFC21.
The solenoid valve is part of the separate fail-safe system and will cut off the gas supply in the case of
insufficient system chimney draught (controlled by the fan pressure switch).
• Connect the earths of the mains supply, chimney fan and solenoidvalve together (SMG).
• Connect the chimney fan and pressure switch to terminals 1–5.
• Connect the SMG to terminals 6–7.
• 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 mains supply to terminals marked ”Supply”.
