Heater Location
The
heater will be mounted in a cockpit locker, lazerette, or
engine area. The heater’s miniature size makes it easy to
tuck away out of sight.
Fuel System
The
fuel metering pump draws fuel from the main boat tank via
a purpose designed standpipe. All fuel lines and clips are
included in the kit. The Airtronic uses minute amounts of
fuel: e.g. D4 Airtronic 0.38 litres/hr on high setting.
Exhaust
The
products of combustion are passed to atmosphere through a
flexible twin wall stainless tubing, pre lagged and over sleeved
and then through a specially designed hull fitting.
Electrics and Switch
The
heater requires a 12v or 24v battery supply: usually taken
through a suitable fuse from the main auxiliary batteries
or suitable auxiliary point. Current draw is minimal (see
specification data). All harnesses are pre cut, sleeved, and
plugs connected for easy installation. Either a simple On/Off
switch with a temperature control dial or digital timer regulate
the temperature in the boat.

The Duct
System
Flexible ducting carries the hot air
to outlets in cabin fascias, such as seat or locker
fronts. The ducting has been carefully chosen for its
layers of integrated insulation and high flexibility
without compromising air flow.

How
the Airtronic works
A single cabin
control switch (1), or a 7 day timer, will start the heater
operation. The heater’s motor will operate the fan (4) drawing
in air for the combustion chamber (2) to mix with diesel.
This is delivered by the remote factory set fuel metering
pump (3). This draws the fuel for the heater from the main
boat’s tank (or a separate tank in the case of a petrol engined
craft).
A glow pin (5) ignites the
fuel air mist and combustion is established. This heats the
heat exchanger (6), and the products of the combustion (7)
are passed out of the heater and on through flexible stainless
steel tube to the exhaust outlet; usually located on the transom,
or boat’s hull. The heater is not connected in any way to
the engine or other boat systems.

|
The fresh air fan (8) draws in cold air
for heating; quite separate from the combustion process. This air
passes over the sealed, finned heat exchanger (6) and under pressure,
passes through the duct work. This delivers the warm air to the
cabins which is automatically controlled to give your desired temperature.
All the components that go to make a full
installation are purpose designed to work together reliably and
withstand the tough marine environment.
