The heater should be installed in a dry and protected
position and within the permissible mounting planes as
shown in Figure 1. Before deciding on the position, be
aware that the location of the exhaust hull fitting and
length of the exhaust may limit where you position the
heater unit. Refer to the exhaust chapter for further
information. Also you must consider ventilation for the
heater and the relative height of the unit with regard to
other water components such as radiators, matrix units
and any expansion tank (header tank / pressure vessel)
that may be used. Further details are shown in the water
pipework chapter of this manual.
Cockpit locker or engine/machinery spaces are ideal
installation locations for the heater.
However, the heater must not be installed into any
accommodation area.
Ideally, the heater is installed with the exhaust and
combustion air connections pointing vertically downward.
Failure to achieve this could affect the optimum
performance of the heater, particularly when sailing at an
angle. The heater will operate in conditions of permanent
15° angle and after starting to a maximum angle of up to
30°.
When deciding on the position, consideration should also
be given for future servicing and access for removal of
the heater.
Please Note!
Depending on the installation space available, the heater
can be moved sideways in the bracket and screwed in
one of the two fastening threads.
