The location selected for installation of the appliance must allow the provision of a satisfactory fl ue, an ad-
equate air supply (for type B
23
), a drain and be well illuminated. A purpose built plant room or compartment is
strongly recommended.
If a purpose built plant room is not available, measures should be taken to protect the appliance from dam-
age and prevent any extraneous matter from being stored on or around the Heater. See BS 6644 Clauses 4,
5 and 6 for details. Any combustible material adjacent to the appliance must be so placed and shielded as
to ensure that it’s temperature does not exceed 66ºC (150ºF).
There must be easy access to the plant room and boiler at all times. The appliance must be located in an
area where leakage from the tank, water connections or the combined temperature and pressure safety
valve will not result in damage to the area adjacent to it. When such locations cannot be avoided, a suitable
drain tray must be installed under the Heater. The drain tray must be no deeper than 38mm and must be
100mm wider and longer than the boiler. It should be piped to an adequate drain using 20mm (0.75in) diam-
eter pipe, angled for proper drainage.
Access must be provided to the front of the boiler with adequate clearance for servicing and operation (See
3.1). The fl oor on which the boiler is installed must be fl at, level and of suffi cient strength to withstand the
weight of it when fi lled with water, and should satisfy the requirements of the Local Authority & Building
Regulations.
This appliance has been supplied with metal plates to fasten the appliance securely to the fl oor. There are
four fl oor fi xing plates (M6644) included with this appliance and these have been packed separately with the
Flue/Air Duct kit. Fix the appliance to a level fl oor using the following method:
1. Slide a plate into position so that it interlocks onto one of the
front supports. Mark fl oor with hole position and remove plate.
2. Drill marked position on fl oor to allow installers preferred
method of fi xing.
3. Refi t plate and fasten through using preferred fi xing method.
4. Repeat method for the other three corner fi xing points.
