WATER HEATER CONNECTION (OPTIONAL)
As an accessory, WESTERBEKE wiJI provide a connector
that directs the engines hot water (coolant) flow to heat the
fresh water
in the ships hot water tank.

The water heater shouKl be mounted in a convenient location
either
in a high or low position in relation to the engine, so
that the connecting hoses from the heater to the engine can
run
in a reasonably direct line without any loops which
might trap air.
Hoses should rise continuously from their low point at the
heater to the engine so that air will rise naturally from the
heater to the engine.
If trapped air is able to rise to the heater,
then
an air bleed petcock must be installed at the higher
fitting on the heater for bleeding air while filling the system.
NOTE: If any portion of the heating circuit rises above the
engine's closed cooling system pressure cap, then a pressur-
ized (aluminum) remote expansion tank (Kit #024177)
must
be installed in the circuit to become the highest point. Tee the
remote expansion tank into the heater circuit, choosing the
higher
of the two connections for the return. Tee at the
heater; and plumb a single line up to the tank's location and
the other back to the engine's return. Install the remote
expansion tank in a convenient location so the fresh water
coolant level can easily be checked. The remote expansion
tank will now serve as a check
and system fill point. The
plastic coolant recovery tank is not used when the remote
expansion
tank kit is installed, since this tank serves the
same function.
