Domestic Hoi Water
All
engine covered in this manual are
equipped with a domestic hot water con-
nection.
If the owner/operator wishes to
connect a hot water heater, remove the
bypass hose and connect a heater as
described
in the instructions presented
below.
General:
With the bypass hose (Part #
30962) removed, there remain two con-
necting points A and
e for hoses to run to
and from the water heater. These connec-
tions assure a
How of hot water through
the heater at all times but do not effect the
flow
of coolant through the engine.
Flow Controller
Installation:
The heater should be mounted conveniently 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. Connection point A on the Flow Control housing should connect to the lower
of the two connections on the water heater while the upper connection on the heater returns to connection
e, nearest to the heat exchanger.
