INSTALLATION
Installation of the R18 should only be carried out by a recog-
nised installer in accordance with the current national and local
requirements, norms and standards (see supplement).
Siting
Install the water heater as close to the chimney as possible. A
plinth base is not required.
To maintain ease of access and therefore ease of maintenance
refer to clearances in figure 1.
If these dimensions are not met, maintenance operations could
be seriously inhibited.
The location chosen for the water heater must permit the provi-
sion of a satisfactory flue system and air circulation around the
water heater, see dimensions.
The water heater must be installed on a level non-combustible
surface capable of supporting it's weight and any necessary
equipment. If the water heater is to be installed on a raised
plinth, the plinth must carry forward by at least 1100 mm in
front of the water heater to allow removal of the burner trolley.
It is important that the water heater is sited so that extraneous
material cannot be stored next to it.
The product has to be installed by a recognised installer fully
ventilation
according to the current national and local requirement, norms
and standards.
Ventilation openings should be placed so that the boiler room is
equally ventilated. More inlet openings in roof top boiler rooms
should be used and situated at regular distances. By internally
or externally casing the inlet openings the negative influence of
wind on the boiler room can be minimised (see fig. 17).
In general, approximately half of the heat transmission in a
boiler room is used to heat the room itself and the other half is
lost through the draught diverter to the outside. To prevent air
stratification, and therefore greater losses, the high level outlets
should be situated as high as possible.
Incorrect or poorly sited boiler room ventilation can lead to high
temperatures in the boiler room, poor combustion and early
failure of control and regulation equipment caused by the high-
er ambient temperatures.
