INSTALLATIONS

These engines are equipped with connections for the plumbing

engine coolant to transfer heat to an on-board water heater.

The

water heater should

mounted in a convenient location

either in a high

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.

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.

The pressure cap on the engine's manifold should be

installed after the engine's cooling system is filled with

coolant. Finish filling the cooling system from the remote

tank after the system is filled and is free

air and exhibits

good coolant circulation. During engine operation, checking

the engine's coolant should

done at the remote tank and

not at the engine manifold cap.

The

hose connection from the

heater to the remote expansion tank should
