Heating

The air heating unit, an Eberspricher, is located under the port side deck, accessible from the wheelhouse. The control switch is on the wheelhouse inside wall, port side.

The exhaust pipe is led through the port topside, beneath the steps to the poop deck. It has a rubber plug, attached to a chain.

The rubber plug should be used when sailing with the heater turned off. When it is turned on, the exhaust pipe can be under water temporarily without the heater going out. Water entered through the exhaust pipe when the heater is turned off will damage the unit. Under normal circumstances rain will not enter an unplugged exhaust pipe.

Always check that the plug is out before you turn on the heater. During winter storage the exhaust pipe should be plugged.

The thermostat, located in the aft cabin, controls the ignition circuit of the heater. Therefore, the heater won’t ignite if the thermostat is set for a temperature lower than the prevailing one. Check the thermostat before turning on the heater!

Mind the burning hot exhaust gas coming out of the exhaust pipe on the port side, especially with regard to neighbouring boats and fenders. A plastic fender will melt from the heat.

On the following page, we have gathered the most important points concerning the use and maintenance of the unit.

The warmth of the engine may also be used for heating the boat. Radiators, installed under the seats, are connected to the engine heat exchanger. The system comprises an expansion tank, through which, in the case, the engine cooling water is filled.

The heater must never be on while the tank is being filled. The heater must never be operated in garages.

Operation with universal switch

Ventilation

• To switch on: Turn knob to “I” position. The control light in the knob glows.
• To switch off: Turn knob to “0” position. The control light goes off.

Heating at full capacity:

• Set the control to “I” (Full). The pilot lamp on the switch will come on. The heater will commence functioning after a maximum of 5 seconds.
• The knob should be switched to “0” when the heater is to be switched off; the pilot lamp will go out. The blower motor continues running until the heater has cooled; it will then be switched off automatically.

Maintenance

Even when the heater is not in constant use, it should be switched on for a brief period approximately once every season.

You can rectify the following faults yourself:

• 1. No noise is emitted by the blower after switching on:
  • a) Check the 16 A fuse in the cable harness of the control unit.
  • b) Check the motor fuse in the control unit.
  • c) Check the glow plug. Change if necessary.
• 2. The blower runs for only 3 minutes after switching on, the heater does not ignite and switches off automatically:
  • a) Switch the heater on and off briefly (not more than twice!). If the heater still does not ignite, have the trouble seen to in a workshop.
• 3. After switching on, the blower only runs for some 20 seconds, the heater does not ignite and switches off automatically:
  • a) Check battery voltage. If voltage < 10.5 V or 21 V, the undervoltage safety device has responded.
  • b) Charge battery, switching the heater off, then back on again.
• 4. The heater goes off during operation or automatically switches off 5 seconds after being switched on:
  • The fault is due to overheating. Switch off the heater, remove the cause of the overheating (e.g. blocked hot air line), press the knob of the safety thermal cutout briefly, and switch the heater back on. If the heater still does not ignite, have the trouble seen to in a workshop.

Please ensure that the heater begins to function approx. 2 to 3 seconds after it has been switched on. The pilot light should come on.
