appliance and consult a CORGI registered engineer. If it is
known or suspected that a fault exists on the appliance it
MUST NOT be used until the fault has been rectified by a
competent person.
DO NOT interfere with any sealed components and use the
appliance only in accordance witth these instructions.
This appliance is not intended for use by persons (including

The method of connection to the mains supply must facilitate
complete isolation of the appliance. Either a 3A fused three pin

ELECTRICAL SUPPLY
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:
System 18 = 88cm

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
front face of the boiler.
4. When installed in a cupboard or compartment it is not
permissible to store other objects in the cupboard. Additionally
no flammable objects/items must be allowed to come into
