Installation and initial start-up
Installation
Ensure suffi cient air ventilation for heater, mini-
mum aperture of 100 / 150 cm
into installation area.
Ensure that the boat is suffi ciently ventilated.
The exhaust pipe outlet must be at least 400
mm (16") away from the opening for fi lling fuel
or tank breather.
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 3 m).
Fuel system
Fuel for the device comes through a separate
tank fi tting, not via a manifold or connection
shared by the engine or other device.
Install the fi lter to the fuel hose before you install
the device, in an accessible location for fi lter
changes.
Fasten the fuel hose couplings tightly. Al-
ways use a sleeve joint on the hose (olive ring).
Make sure that the surfaces of the couplings are
clean before fastening them.
The hoses must be kept clean during installa-
tion.
Use only Wallas fuel hoses.
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.
Cut the fuel hoses to the appropriate length
when installing them.
Electrical installation
The nominal voltage of the device is 12 VDC.
Current for the device is taken directly from the
battery terminals using cables that are as short
as possible.
Put the main fuse of c. 15 A on the + cable close
to the battery.
Exhaust fumes
When choosing the outlet location, note that
exhaust fumes are hot.
Use a goose-neck to prevent splash water en-
tering the boat from splashing into the outlet.
If your boat has a metal hull, the device and
outlet must be insulated from the hull to prevent
electrochemical corrosion.
The exhaust pipe must not come into contact
with combustible materials. Insulate the exhaust
hose, if necessary.

Installation
Initial start-up
The device usually does not start the fi rst time after
(16 / 24 sq. in.)
it has been installed. It may take several starts (c.
2
4-6) for the fuel hoses to fi ll up enough for the fuel to
reach the burner.
Watch the hoses as they fi ll 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 fi ll 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.
