Hoses should rise continuously from their low point at the heater

the engine so that trapped air will rise

naturally from the heater to the engine. If trapped air

able rise

the heater, then an air bleed petcock must

installed at the higher fitting on the heater for bleeding air while filling the system. Avoid loops in hose

runs which will trap air.

Note:

If any portion

the heating circuit rises above the engine's own pressure cap, then a

pressurized (aluminum) remote expansion tank

must be installed in the circuit

become the

highest point. The remote expansion tank's part number

24177. Install the remote expan-

sion tank in a convenient location such as in a sail locker so the fresh water coolant level can

easily

be c hec ked.

The cap on the engine mounted expansion tank should not be opened once the remote system

installed

and filled.

The hose connection from the heater

the remote expansion tank should be routed and supported so as

rise continuously from the heater to the lank, enabling any air in the system to rise.
