6 - CIRCULATING PUMP CHARACTERISTICS

The

circulating

pump

is

equipped

with

a

3-speed

motor

with

a

maximum

input

power

of

88

W.

The

electrical

power

consumption

of

the

heating

cir- culating

pump

can

be

greatly

optimised

by

adapting the

speed

to

the

requirements

of

the

installation

by using

the

optional

control

devices

proposed

(section 4

-

chapter

IV

-

INSTALLATION).

7 - EXPANSION VESSEL CHARACTERISTICS

GWR

boilers

come

equipped

with

a

12

litre

expan-

sion

vessel.

This

vessel

has

a

useful

capacity

of

7.5

litres

with

a

head

of

5

metres,

which

is

satisfactory

up

to

a

total

installation

capacity

of

125

litres

for

a

maximum

temperature

of

80°C.

For

higher

capacities,

plan

for

an

additional

expansion

vessel.

The

expansion

vessel

absorbs

the

increased

vol-

ume

of

water

in

the

system

caused

by

the

rise

in

the

water’s

temperature.

The

pre-inflation

of

the

vessel

pushes

the

internal

membrane

on

the

connection

side

and

the

expansion

of

the

water

pushes

down

on

this

membrane.

boilers

only

have

a

single

sheath

receiving

the

heating

elements

(7,

fig.

5).

The

GWR

18

boilers

have

two

sheathes

(7,

fig.

5).

The

control

system

of

the

GWR

boiler

automatically

adapts

its

power

to

the

power

requested

by

the

in-

stallation,

in

sections

of

1/3,

2/3

or

3/3

of

its

maxi-

mum

power.

Example:

For

a

GWR

18

boiler

of

18

kW

-

If

the

power

requested

is

less

than

6

Kw ( = mild

outside temperature)

•

the

boiler

controls

between

0

and

6

kW,

namely

between

0

and

1/3

of

its

maximum

power.

-

If

the

power

requested

is

10

kW

(6

kW

<

P

<

12

kW): (= cool

outside temperature)

•

the

boiler

controls

between

6

and

12

kW,

namely

between

1/3

and

2/3

of

its

maximum

power.

-

If

the

power

requested

is

15

kW

(12

kW

<

P

<

18

kW) ( = cold outside temperature)

•

the

heater

regulates

between

12

and

18

kW, namely

between

2/3

and

3/3

of

its

maximum power.

-

If

the

power

requested

is

greater

than

or

equal

to

18

Kw ( = very cold outside temperature)

•

the

boiler

is

at

its

maximum,

namely

3/3

of

its

maximum

power

(18

kW).

INSTALLATION

2 - ASSEMBLY

Before

any

intervention,

cut

off

the

!

power

supply.

The

boiler

must

be

installed

in

an

area

suitable

for

its

protection

index

(IP

x

2D),

on

a

wall

that

is

solid

enough

to

support

the

weight

of

the

boiler

when

it

is

filled

with

water.

For

normal

working,

the

cover

must

be

mounted

and

secured

with

screws.

To

allow

the

resistances

to

be

removed,

a

distance

of

250

mm

between

the

top

of

the

boiler

and

the

ceiling

must

be

re-

spected.

-

Remove

the

cover

after

removing

the

two

screws

located

in

the

lower

part

of

each

side

of

left

without

a

control

valve

or

a

differential

valve

must

be

installed

so

that

there

is

al-

ways

a

correct

minimum

flow

in

the

boiler.

For

assembly

on

ensure

that

the

to

eva-

cuate

any

stagnant

mud

in

the

1 - PROTECTION OF THE INSTALLATION

Atlantic

2000

recommends

the

use

of

the

following

heating

system

water

conditioning

products:

!

-

AL16

corrosion

inhibitor

(or

equivalent

products),

1.1

-

AL16

is

a

non-toxic,

biocide,

traceable

corrosion

inhibitor

specially

designed

to

protect

multi- metal

heating

circuits.

Through

its

efficient

means

of

acting

against

all types

of

corrosion

and

all

types

of

bacteria,

AL16

-

Prevents

the

formation

of

rust

and

metallic sludge,

-

Prevents

the

formation

of

algae

and

bacteria sludge,

-

Also

suitable

for

under-floor

heating

systems,

-

Prevents

hydrogen

build

up,

-

Contains

an

internal

marker

so

that

doses

can

be easily

controlled.

AL16

DOSAGE:

-

Without

under-floor

heating:

or

connection

using reinforced

polyethylene

type

pipes:

1%

(0.5

l

of

AL16

for

50

l

of

water).

-

With

under-floor

heating

or

radiators

connected

in reinforced

polyethylene

type

pipes:

2%

(1

l

of

AL 16

for

50

l

of

water).

.

Important warning

AL16

must

only

be

put

in

a

clean

installation

that

has

been

checked.

It

is

!

therefore

imperative

to

fill

the

entire

system

one

or

more

times

with

clean

water

as

required.

In

some

cases,

the

system

may

need

washing

by

a

suitable

product:

Example:

-

In

a

new

installation:

To

detect

any

leaks

and

eliminate

any

traces

of

welding,

weld

solder

or

other

residues.

-

On

an

old

installation:

To

eliminate

any

trace

of

sludge

and

other

products

in

the

radiators,

under-floor

heating

system

and

the

boiler.

The

boiler

must

be

empty

when

filling

!

with

antifreeze.

2 - FILLING THE INSTALLATION WITH WATER

-

Filling

the

installation:

•

open

the

heating

flow/return

valves,

if

neces-

sary,

•

fill

the

installation

slowly

(to

make

degassing

easier)

by

using

the

filling

valves

of

the

discon-

necter,

•

close

the

filling

valves,

•

check

the

leaktightness

of

the

circuit,

•

bleed

the

entire

installation,

particularly

the

ra-

diators.

Continue

to

fill

the

system

until

a

pres-

sure

of

approximately

1

bar

is

reached.

3 - VERIFICATIONS PRIOR TO COMMISSIONING

-

Check

that

the

boiler

is

filled

with

water

and

under

pressure

(1

bar),

-

check

that

the

electrical

connections

of

the

boiler

are

correct:

230

V

single

phase

or

400

V

three-

phase,

earth

connection

compliant,

polarities

cor-

rect,

-

check

that

the

electrical

cables

are

tightened

properly

at

the

terminal,

safety

switch

and

contactors

-

check

that

the

automatic

bleeds

are

working

cor-

rectly.

To

do

this,

before

starting

to

heat,

correctly

bleed

the

boiler

and

the

installation

and

ensure

that

the

pressure

is

not

less

than

0.8

bar

(mini-

mum

pressure

that

triggers

the

lack

of

water

se-

curity

mechanism).

4 - USER INFORMATION

The

heating

engineer

must

operating

mode.

In

particular

the

user

must

be
