FROM

ON

WESTERBEKE provides easy access

for

connecting

to

an

on-board hot

water

system.

These connections

allow

for

the

engines hot water (coolant)

to

flow

to

the

ships

hot

water

tank,

heating

the

fresh

water and

then

cycling

back

to

the

engine.

The water heater should

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.

PETCOCK

\

NOTE:

An air bleed petcock

is

located

on

the

engine:V

heat

exchanger

and

on

the

thermostat

housing.

Open

these

petcocks

when

filling the engine s coolant system

to

allow air

to

escape.

Close

both

tightly after all

the

air

is

removed.

NOTE:

If

any portion

0/

the

heating

circuit

rises

above

the

engine S closed cooling system pressure

cap,

then

a

pressurized (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,

choos-

ing

the higher a/the

two

connections/or

the

return.

Tee

at

the

heater;

and plumb a single line

up

to

the

tanks

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

The

plastic coolant recovery

tank

is

not

used when

the

remote

expansion tank kit

is

installed,

since

this·

tank

serves

the

same function.
