comes

complete

wi

th

a

Flow

Control

which,

when

proper

ly

connected

to

a

heater

tank,

produces

domestic

hot

water

from

waste

engine

heat.

Principle:

With

the

bypass

hose

130962

removed,

there

remain

2

con-

necting

points

A

and

B

for

hose

to

and

from

the

water

heater.

These

connections

assure

a

flow

of

hot

water

through

the

heater

at

all

times

and

yet

preclude

excessive

restriction

of

engine

cooling

water

flow

caused

by

the

heater

-

all

simply

and

automatically.

Installation:

The

heater

should

be

mounted

conveniently

either

in

high

or

low

position,

so

that

connecting

hoses

from

heater

to

engine

can

run

in

reasonably

direct

line

without

loops

which

might

entrap

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

B,

nearest

the

heat

exchanger.

Hoses

should

rise

continuously

from

their

low

point

at

the

heater

to

the

engine

so

that

trapped

air

will

rise

naturally

from

the

heater

to

the

engine.

If

trapped

air

can

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.

Avoid

loops

in

hose

runs

which

will

trap

air.

If

any

portion

of

the

engine

cooling

water

circuit

to

or

from

the

heater

rises

above

the

engine's

own

pressure

cap,

then

the

pressurized

remote

expansion

tank

must

be

installed

in

the

circuit

to

become

the

highest

point.

The

tank

kit

part

number

is

24177.

Install

the

remote

expansion

tank

in

a

convenient

location

such

as

a

sail

locker

for

ease

of

checking

fresh

water

coolant

level.

The

cap

on

the

engine

mounted

expansion

tank/manifold

should

not

be

opened

once

the

remote

system

is

installed

and

filled.

The

hose

should

be

heater

to

connection

from

the

heater

routed

and

supported

so

as

the

tank

enabling

any

air

in

to

to

the

the

remote

expansion

tank

rise

continuously

from

the

system

to

rise.
