Installation and initial start-up
Installation check list before test-run
Installation
Read manual and use only official Wallas parts
Ensure that the boat/cottage/location is sufficiently ventilated.
In boat heaters the exhaust pipe outlet must be atleast 400mm(16”) away from the opening for filling fuel or tank
breather.
We recommend installing the control panel on a vertical surface where liquids are not able to leak into the
switch and it is out of reach of children.
Fuel system
Fuel for the device comes through a separate tank fitting, not via a manifold or connection shared by the engine
or other device.
Install the filter to the fuel hose before you install the device, inanaccessible location for filter changes.
Fasten the fuel hose couplings tightly. Always 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 installation.
If the surface of the fuel tank is above the device, 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.
In boat heaters use a goose-neck in exhaust pipe to prevent splash water entering.
If your installation location is a boat with 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.
Warm air outlet(Spartan and Viking models only)
If your heater has air hosing, do not reduce air hosing too much. Recommendation of ø 75 mm outlet is to divide
it to two ø 60 mm outlets.
It is recommend to insulate the warm air hoses to save energy.
Note! All warm air vents are not allowed 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.
Follow the instruction for unlocking the device and try again.
When the device starts, look for possible leaks in the exhaust and fuel connections.
Run the device for c. ½ hour to allow possible installation and manufacturing greases to burn off. Make sure
there is enough ventilation.
Remember to carefully read the instructions for installing, operating and servicing each device before
installation.
