INSTALLATIONS

These engines are equipped with connections for the

plnrnbing

engine coolant to transfer heat

an on-board water

heater.

The water heater should be mounted in a convenient location

either

that the connecting

hoses

from the heater

the engine can

run in a reasonably direct line without

any
