Eberspracher Airtronic D2 Installation Manual - Planning Your Installation
Planning your installation
9

Before you begin, we advise that you take some time to
plan the installation.
Where and how you install your system will depend
on various limitations of both your boat design and
construction as well as the technical specification of the
heater. Because of this we have endeavoured to give
helpful advice within the different sections of this manual,
so we advise that each section is read fully before
commencing the installation.
As a general guide before you begin, be aware of the
location of the boat’s fuel and water tanks, the batteries
and any cold box, fridge or cooker that may prohibit the
routing of the hot air ducting or affect the installation.
Before installing the heater into the boat, ensure that in
doing so you are not infringing upon, or contravening
any legal requirements of the boat’s use or construction.
For instance, if the boat is to be used for hire purposes,
it may require additional systems or warning labels to be
installed, which may not be mentioned in this manual.
Similarly, advice from the boat manufacturer may be
required if you plan to cut through bulkheads that may be
structurally important to the boat design.
Regulations that could affect the installation of the heater
may be different in each country / region, so please
check.
Remember additional parts are available.

Installation Considerations
Are all cabins to be heated? If you decide not to heat
a cabin it is worth bearing in mind that a large cold
area will condensate and become damp as the heater
warms and dries the rest of the boat.
Are the heads (toilets) to be heated? The warmer
the boat becomes the colder these areas feel, it is
often a mistake to not have them heated. In a sail boat
a warm heads can be used as a hanging locker for
drying wet clothing. Heads outlets should be kept small
(50mm) and branch off the main duct run.
Are any white outlets required? (Normally used for
heads or cockpit outlets if the boat has a white finish).
Is an exhaust silencer required? The Eberspächer
silenced marine exhaust is extremely effective at
silencing exhaust noise. (Under no circumstance
should any other type of silencer be used, vehicle
exhaust silencers are NOt gas tight).
2m 24mm silenced exhaust 29.2199.01.4506.
2m 30mm silenced exhaust 29.2199.01.4157.
Is an acoustic intake duct silencer required? These
are effective at silencing any blower motor noise heard
at the intake.

100mm Silencer 25.1226.89.5600.
Is an acoustic output duct silencer required? These
are effective at silencing any blower motor / air noise
heard at the output vents.
75mm Silencer 25.1226.89.1500.
90mm Silencer 25.1226.89.1700.
100mm Silencer 25.1226.89.5600.
Windscreen demist options for motor boats and
work boats. An electronic duct diverter valve is
available for demist or cockpit heating options, please
contact your local dealer for further information.
Is duct lagging required? Lagging can significantly
increase the air temperature at the furthest outlets and
should be considered when installing a small heater
into a large boat or long duct runs are involved.
