LOCATION
The location selected for installation of the appli-
ance must allow the provision of a satisfactory flue,
an adequate air supply (for type B23), 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, meas-
ures should be taken to protect the appliance from
damage 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 ma-
terial 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 con-
nections or the combined temperature and pres-
sure 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) diameter pipe, angled for
proper drainage.
Access must be provided to the front of the boiler
with adequate clearance for servicing and opera-
tion. (Fig 1.1)
The floor on which the boiler is installed must be
flat, level and of sufficient strength to withstand
the weight of it when filled with water, and should
satisfy the requirements of the Local Authority &
Building Regulations.
Whether connecting to an existing or a new
heating system, a filter/strainer (with two
isolation valves) must be fitted in the return
pipe. When necessary it can be removed
and cleaned, which will help protect the
appliance from contaminants, from within
the heating system.
APPLIANCE FLOOR FIXING KIT

another two plates have been used to fasten the
appliance to the pallet.

face, fix the appliance to the floor using the follow-
ing method.
