This appliance must be earthed.
Supply: 230V - 50Hz fused at 3A.
The method of connection to the mains supply must facilitate
complete isolation of the appliance. Either a 3A fused three pin
plug and unswitched shuttered socket outlet, or a 3A fused
double pole switch having a 3mm contact separation in both
poles, serving only the boiler (and its external controls), may
be used.
1. A flat vertical area is required for the installation of the
boiler.
2. Where an open flued (B23) system is used then an air vent
must be provided in the same room or internal space of the
flue duct air inlet, with a minimum free area of:
Dimplex 24 = 88cm
2
Dimplex 30 = 121.5cm
2
Dimplex 38 = 159cm

3. These dimensions include the necessary clearance around
the boiler for case removal, spanner access and air movement.
Additional clearances may be required for the passage of pipes
around local obstructions such as joists running parallel to the

If the pressure exceeds 3 bar the pressure relief valve will
operate and a fault may be indicated. Contact your installer
