Water Pressure Pump

Regulate the flame with the regulator knob:

• Big flame right, small flame left.
• Turning the water control knob counterclockwise increases the water amount, and turning clockwise decreases it.

The most economical positions are: flame in the middle and water amount small. If you use the shower, both flame and water amount should be at maximum.

The pilot light is always burning when the heater is on duty. The flame can be turned off by pushing the flame regulator to the left. The pilot light has an automatic flame guard. When you hear a slight snap about 15 seconds after turning the light off, you know that the flame guard works properly. As a safety measure, the gas valves can also be shut off.

CAUTION!
Get the air out!

If the air is not properly expelled from the fresh water system, and particularly the warm water branch, the low water pressure will turn the heating flame on although no water is used. The heater will be overheated and may become the start of a fire on board. When you notice that you are about to run out of fresh water, turn the heater off immediately. It absolutely requires proper pressure for safety.

Raritan Water Heater

A NAUTICAT may be equipped with an optional Raritan water heater, a well-insulated container (taking 25 litres = 5.5 GB, 6.5 US gallons) through which the engine cooling water circulates in a spiral. The water in the container gets as hot as the cooling water of the engine. The temperature can be seen from the engine temperature gauge. The water will remain warm overnight (the temp falls about 30°C though) and is hot again after running the engine for five minutes. This heater is always ready for use, and it requires no operation. It is installed on the port side of the engine bay.

As an option, the Raritan heater has a 220 V heating unit which can be connected to shore power. The unit has a thermostat control (90°C).
