FUEL CONNECTION
- Fuel is supplied through a suction hose from either a separate tank (connection 1016), from
the diesel tank via an adapter (1016/2) or with a tank connection kit (2265).
- The cooktop should be placed above the liquid level of the tank. The fuel line must be above
the fuel level of the tank all the way before the pump (prevents siphoning in the event of a
hose failure).
- The fuel lines and the tank must be carefully secured and protected from heat and mechanical
impacts.
- The fuel pump must be fitted near the tank, above the liquid level with the suction side down.
You can disconnect the fuel line and pump power wires from the cooktop’s side during
installation. The wires of the pump can be connected either way round. If you need a longer
fuel hose, you can increase the length of the hose between the pump and the tank by
replacing the entire hose, thus avoiding splicings and the possibility of air leaks that they bring.
- Be careful not to attach the pump to rigidly to the structures as this may cause resonation.
ELECTRICAL CONNECTIONS
- The cooktop operates at 12V DC. It is recommended to use the 12V auxiliary battery if the
boat is equipped with one. A sufficiently efficient 24/12V voltage converter must be used in
24V systems, e.g. Victron Energy Orion 24/12 12A.
- It is advisable to connect the power cables of the heater directly to the battery. Please note
that the minimum conductor area in mm
2
corresponds to the length of the cable in metres. If
longer cables are needed, the original wires of the cooktop (2.5mm
2
) must be replaced with
thicker wires by cutting the wires max. 0.5m from the cooktop and connecting a thicker wire
with a good-quality terminal block. Wire colours red = +, yellow =
–.
Be careful
not to connect
the wires with reversed polarity. When disconnecting power from the main power switch, it is
important to allow the aftercooling to complete. It is also advisable to always switch off the
cooktop from the control panel.
- Wiring diagram (Figure 3).
- The + lead from the battery must be protected by a slow 15A fuse. The heater circuit board
has an automatic main fuse F1.
- A high-power bow thruster is a risk factor for electrical interference.
Please note
that the outside of the heater is galvanically connected to the battery terminal.
