Danger!
Risk of injury and burns!
All combustion processes produce high temperature and
toxic exhaust fumes. This is the reason why the exhaust
system must be installed to these instructions.
• Do not perform any work on the exhaust system while
the heater is in operation.
• Before working on the exhaust system, first switch
off the heater and wait until all parts have cooled
completely. If necessary, wear suitable gloves.
• Do not inhale exhaust fumes.
• Do not operate the heater in enclosed spaces such
as a boat shed or when the boat may have a cover
fitted in winter, etc.

Combustion air
The combustion air components are supplied in
the installation kit. A silencer, extension tube and a
combustion air hull fitting are available as optional parts.
The combustion air silencer and tube should be installed
as shown in Figure 10.
If combustion air is to be taken from an engine/
machinery space, please ensure it is adequately vented
and that the area will not be pressurised or under partial
vacuum when the engine is in use or ventilation fans are
running.
If it is to be taken directly to an external hull fitting ensure
that it is positioned with regard to the same conditions as
required for the exhaust hull fitting.

Caution!
Safety instructions for the combustion air system
• The position of the combustion air must not allow
exhaust fumes or flammable vapour to be drawn in.
• If a combustion air hull fitting is used ensure water
ingress is not possible at any time.
• The combustion air inlet must not be restricted or
blocked at any time.
• The combustion air must not be drawn from any of
the accommodation areas.
• The combustion air inlet must be drawn from a neutral
pressure area.
