Installation and initial start-up
Installation
F Ensure sufficient air ventilation for heater,
minimum aperture of 100 cm
installation area.
F Ensure that the boat is sufficiently ventilated.
F The exhaust pipe outlet must be at least 400
mm (16") away from the opening for filling fuel
or tank breather.
F We recommend installing the operating switch
on a vertical surface where liquids are not able
to leak into the switch and it is out of reach of
children (cable length 6 m).
Fuel system
F Fuel for the device comes through a separate
tank fitting, not via a manifold or connection
shared by the engine or other device.
F Install the filter to the fuel hose before you install
the device, in an accessible location for filter
changes.
F Fasten the fuel hose couplings tightly. Al-
ways use a sleeve joint on the hose (olive ring).
F Make sure that the surfaces of the couplings are
clean before fastening them.
F The hoses must be kept clean during installa-
tion.
F Use only Wallas fuel hoses.
F If the surface of the fuel tank is above the de-
vice, a magnetic valve must be installed into the
fuel hose close to the tank.
F Cut the fuel hoses to the appropriate length
when installing them.
Electrical installation
F The nominal voltage of the device is 12 VDC.
F Current for the device is taken directly from the
battery terminals using cables that are as short
as possible.
F Put the main fuse of c. 15 A on the + cable close
to the battery.
Exhaust fumes
F When choosing the outlet location, note that
exhaust fumes are hot.
F Use a goose-neck to prevent splash water en-
tering the boat from splashing into the outlet.
F If your boat has a metal hull, the device and
outlet must be insulated from the hull to prevent
electrochemical corrosion.
F The exhaust pipe must not come into contact
with combustible materials. Insulate the exhaust
hose, if necessary.

Warm air outlet
F ø 75 mm air hose is not allowed to reduce to 60
mm hose. The only permitted is to devide one ø
75 mm outlet to two ø 60 mm outlets.
F It is recommend to insulate the warm air hoses.
F Note! Warm air registers are allowed not to be
closed at the same time.
Initial start-up
The device usually does not start the first time after
it has been installed. It may take several starts (c.
4-6) for the fuel hoses to fill up enough for the fuel to
reach the burner.
Watch the hoses as they fill up as you start the
device.
After two unsuccessful start-ups, the device
will lock. (The yellow and red LED lamps will blink
simultaneously indicating a lock-up.)
Follow the instruction for unlocking the device
and try again.
Watch the hoses fill up with fuel while you start the
device.
When the device starts, look for possible leaks in
the exhaust and fuel connections.
Run the device for c. ½ hour to allow possible instal-
lation and manufacturing greases to burn off. Make
sure there is enough ventilation.
Remember to carefully read the instruc-
tions for installing, operating and ser-
vicing each device before installation.
