INSTALLATIONSECTION 3
INTRODUCTION
LOCATION
THE LAW REQUIRES THAT INSTALLATION IS CARRIED OUT BY A
PROPERLY QUALIFIED PERSON
Installations must be carried out in accordance with Gas safety (Installation and Use)
Regulations 1998, Building Regulations, The Water Supply (Water Fittings) Regulations
1999 and any requirements of the local Gas Authority, Local Authority, Water and Fire
Authorities and the current British Standards and Codes of Practice listed in Section 1.
The location selected for installation of the heater must allow the provision of a
satisfactory flue, adequate air supply, drain facilities and must be well illuminated.
A purpose built boiler room or compartment is strongly recommended.
A manual valve for isolation of the plantroom should be installed in the gas supply; it
should be clearly identified and readily accessible for use at all times.
If a purpose plantroom room is not available, measures should be taken to protect the
heater 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.
The heater must not be installed in any location which contains a bed, bath or shower.
There must be easy access to the plantroom and heater at all times.
The water heater must be located in an area where leakage from the tank, water
connections or the combination temperature and safety valve will not result in damage to
the area adjacent to the water heater. When such locations cannot be avoided, a suitable
drain tray must be installed under the water heater. The drain tray must be no deeper
than 38mm (1.5in) and have a minimum length and width of 100mm (4in) wider than
the heater. The drain tray must be piped to an adequate drain using 20mm (0.75in)
diameter pipe, angled for proper drainage.
Access must be provided around the water heater to provide adequate clearance for it's
servicing and operation.
The floor and plinth on which the heater is installed must be flat, level and of sufficient
strength to withstand the weight of the heater when filled with water, and should satisfy the
requirements of the Local Authority & Building Regulations.
Any Combustible material adjacent to the heater must be so placed and shielded as to
ensure that it's temperature does not exceed 66ºC (150ºF).
All service clearances for the water heater must be maintained as specified in this
Installation Manual.
