INSTALLATION
SECTION 3
THE LAW REQUIRES THAT INSTALLATION IS CARRIED OUT BY A
PROPERLY QUALIFIED PERSON
Installations must be carried out in accordance with current Building Regulations, The
Water Supply (Water Fittings) Regulations 1999 and any requirements of the 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. If a purpose built
boiler 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.
There must be easy access to the boiler room and heater at all times.
The heater must not be installed in a room which contains a bath or shower and must
not be installed in a bedroom or bedsitting room.
We recommend that adequate clearance is left around the heater for fitting and servicing
purposes with no obstruction at the front of the heater to allow easy access to the
burner. Service clearance above all the heaters except heater models OFS25 should be
1270mm for removal of the flue baffle. Heater model OFS25 flue baffle is hinged for low
ceiling removal. It is very important that heater models OFS108 & OFS163 have at least
600mm clearance at the rear for the installation and removal of the T/P valve if fitted.
We will supply magnesium articulated anodes part No.C333 as a service replacement for
all heater models this will be beneficial where lack of head room is a problem.
The floor on which the heater is installed must be non combustible, level and of sufficient
strength to withstand the heater weight when filled with water. Any combustible material
adjacent to the heater must be placed or shielded as to ensure that its temperature does
not exceed 65
o
C (150
o
F).
Every Andrews oil fired water heater is supplied with a purpose matched burner
assembly. The burner is supplied complete with nozzle factory fitted for use with
kerosene-class C
2
only. If the appliance is to be used with gas oil-class D
1
the nozzle must
be changed before the burner is fitted to the water heater. The correct nozzle specified
for use with gas oil is supplied in the nozzle burner box. It is the responsibility of the
installer to ensure that the correct nozzle is fitted to suit the fuel to be used with this
appliance.
