Thermostat unit
:
5.Air distribution:
The hot air ducting should be run through the boat in the most direct route possible
-
the less bends the better the air
flow
!
The MY
16
uses
55
mm ID ducting so use a
60
mm hole saw to allow clearance when running the ducting through
bulkheads and partitions
,
the MY
30
uses
80
mm ID ducting so use a
90
mm hole saw
.
The hot air outlets require a
95
mm hole saw for mounting
.
There are
2
types
,
the directional vent and the open
/
close
vent
.
There must always be at least one permanently open vent on the installation to prevent overheating of the unit
.
The MY
16
vents have an extra plug in reducer on the back of the outlet to accept the
55
mm hot air ducting
. (
see
dia
7
).

When the holes have been drilled for mounting the hot air outlets they should be secured using the 4

s self tapping screws provided
.
It is advisable to secure the
55
mm reducers with a self tapping screw to
prevent them working
loose
-
especially on motor boats
.
Air inlet
:
This is usually taken from within a well ventilated locker
,
but if for instance the heater was mounted in an engine
room then it would be necessary to duct the inlet air to the heater to prevent any fumes being drawn into the cabin
area
.
The inlet ducting should always be kept to a minimum length to prevent any restriction in air flow
.
