Introduction

The Benson Jetstreme 4+ series of

highly

efficient oil fired boilers

combine

the

benefits of

advanced design with well proven construction techniques

and

modern

manufacturing processes.

They operate at high efficiency with clean combustion

and a low

operating noise level.

The heat exchanger is enclosed within

an

insulated jacket

with

secondary insulation attached

on

the

inside ofthe

case. The case is finished

in

white

powder

coat enamel

and

is styled to blend into

any

kitchen. The controls are enclosed behind

an

hinged panel

on

the

front of

the

appliance

thus

reducing possible accidental

damage

to them.

A flame viewing port facility is located

at

the

front of the boiler directly behind

the

front panel.

A combustion test point is located

on

the flue spigot

of

the

boiler to enable the commissioning

engineer to carry

out

his setting checks at a convenient point.

The Jetstreme 4+

range

is available for

both

Conventional

and

Balanced Flue systems.

The
Balanced Flue range is extremely versatile offering several configurations for the installation of the
terminal.

The Jetstreme 4+ range

of

both Conventional

and

Balanced Flue Appliances are designed to

operate

on

Kerosene fuel oil

(28

sec). The Conventional Flue appliance can also

be

operated

on

gas

oil

(35

sec), however

it

is not recommended that

the

Balanced Flue appliances are operated

on

this

fuel as combustion problems could occur. All boilers are supplied

with

the

burners

adjusted for

use

with Kerosene (class C2)

28

sec fuel oil. Should the

use

of

gas oil (class D) 35 sec

be

required to

be

used with a Conventional Flued appliance

then

the modification

must

be

carried

out

at

the time

of

installing

and

commissioning.

Although the Jetstreme range of boilers will operate successfully

on

a gravity

hot

water system

it is recommended that a fully

pumped

system is used for both hot water

and

central heating

if

installing a

new

system. The boiler is suitable for

open

vent

and

pressurised systems, however if a

pressurised

system

is

used,

the

manufacturers

recommendations

for

the

use

of

the

auxiliary

components

must

be

adhered

to,

and

pressure

must

not exceed

45

psi

(3

bar).

The Jetstreme

4+

boiler is

approved

by

BSRIA

(the Building Services Research & Information

Association) for OFTEC.

Combustion

Chamber

Size

Location

The

Jetstreme 4+

must

be

located

on

a level

non-inflammable

surface

that

can

withstand

the

weight

of

the

boiler

and

associated

equipment.

The

boiler

location

must

permit

adequate

ease

of

access for

maintenance

and

servicing.

It

is

recommended

that

the

following clearances

should

be

provided:-

Above

the

boiler

600mm

(24 inches)

To

either

side

25mm

(1

inch)

In

front

900mm

(36 inches)

When

choosing

a site for

the

boiler,

the

major

consideration

is

the

provision

of a suitable

flue

system

and

whether a Conventional

type

flue

or

a Balanced Flue

type

should

be

used.

Consideration

must

be

given

to

the

required

position

of

the

flue, access of

the

oil

supply

from

the

storage

tank,

and

the

location

of

the

air

vents

that

may

be

required.

If

the

boiler

is

to

be

located

within a compartment

or

cupboard

then

the

compartment

or

cupboard

must

be

constructed

or

modified

for

the

purpose

intended.

Details

of

these

requirements

are

given

in

BS

6798: 1987 Specification for

the

installation of

Gas

Fired

Hot

Water Boilers

of

Rated

Input

not

exceeding 60 kW.

Conventional Flue

If

the

flue is

on

the

outside

of

the

building

then

the

flue

must

be

of

the

insulated

twin

wall

type

to

eliminate

the

possible

formation

of condensate.

The

flue

should

rise

as

near

vertically

as

possible

to

its

maximum

possible

length

before

any

bends

are

included.

The

number

of

bends

should

be

kept

to

an

absolute

maximum

of

two.

No

bend

should

have

an

angle

less

than

135°.

No

part

of

the

flue

internal

diameter

should

be

less

than

that

of

the

flue

outlet

spigot

diameter

on

the

boiler.

A

brick

chimney

should

be

lined

with a suitable

stainless steel flue

pipe,

or

other

suitable

non-

combustible

lining,

with

the

void

between

the

lining

and

the

masonry

filled

with a suitable

insulating

material

e.g. vermiculite.

The

chimney

must

always

be

swept

before

the

fitting

of

a liner.

A

draught

stabiliser

must

not

be

used

unless

the

flue

pull

is

found

to

be

excessive.

The

flue

outlet

should

terminate

at

least

600mm

(24 inches)

above

the

apex

of

the

roof, if this is

not

practical,

or

it

is

found

that

the

appliance

is

being

subjected

to a down

draught,

then

an

approved

cowl

should

be

fitted to

eliminate

this condition.

The

fitting

of a suitable

cowl is

always

recommended.

4

Balanced Flue

Jetstreme 4+ boilers

are

designed

to

also

use

a Balanced Flue

system,

whereby

the

appliance

is

completely

sealed

from

the

room

where

it is installed.

Air

is

taken

directly from

the

outside

of

the

building

to

the

burner

for

combustion,

and

then

discharged

again

to

the

outside

of

the

building.

It

is

sometimes

found

that

the

burner

noise level is increased

when

passing

through

a

normal

inlet/exhaust

pipe,

but

the

Jetstreme

4+

inlet/exhaust

also

incorporates a silencer

to

reduce

this effect.

The flue kit

may

be

positioned so as to

pass

through

the

wall to

the

rear,

or

through

a side wall

to

the

left

or

right,

taking

due

account of

the

building

regulations

and

the

recommendations

shown

in

fig

5.

The

standard

flue kit is suitable for walls

up

to

11

inches thick. For walls

up

to 22 inches thick a

supplementary

kit is available

and

can

be

ordered

directly from Benson Heating,

quoting

Flue

Kit

No.1.

Flue

Kit

No.2.

This kit enables

the

balanced flue to

be

discharged

through

the

wall

at a high

level

(2

metres) above

the

floor.

Flue

Kit

No.3.

This kit,

although

still a

balanced

flue system, is suitable for situations

where

the

only

route for

the

discharge is

through

a flat

or

shallow pitched roof.

The

terminal

guard

basket

supplied

with

the

balanced

flue kit

must

always

be

fitted

even

at

high

level.

If

the

balanced

flue

terminal

discharges

within

900mm

(3

feet)

below a plastic

gutter

or

overhang,

the

gutter

must

be

protected

with

a non-combustible material.

Burner

Various

burners

are available for

use

on

the

Jetstreme 4+ boiler

and

all are rigorously tested for

their

suitability. Because

burners

may

be

added

to

the

range

from

time

to

time,

details

of

the

burners

are given

within a separate

document.

It

should

be

noted

that

the

EOGB

burner

is referred

to here; this is because

the

initial external BSRIA

approvals

for

the

Jetstreme 4+

were

carried

out

with

the

EOBG 'Burner fitted.

Oil

Supply

Any

fuel oil leak,

however

small must

be

rectified immediately.

Careful consideration

must

be

given to

the

siting of

the

oil storage tank,

taking

account of:-

Access for delivery

of

oil.

Proximity

and

relationship

of

tank

to boiler.

Visual acceptability

by

the

customer

and

neighbours.

Conformity

to local bylaws.
Building Regulations.
Protection for

the

retention

of

oil

in

the

event

of a leak.

Plastic oil storage

tanks

should

comply

with

OFS

TlOO

and

should

be

OFTEC

Approved

under

the

OFCERT Scheme.

5

Gravity One Pipe System

It

is recommended that the oil tank is situated so that the oil outlet from the tank is not less

than

lOOmrn

(4

inches) above the oil

burner

pump.

This will

permit

the

use

of a gravity feed system

from

the

tank to

the

burner. The oil tank outlet

must

not

exceed 4 metres (13 feet approx.) above

the

burner

pump.

All Jetstreme

4+

appliances are supplied ready to

be

used

on

a gravity system.

If

it is

not

possible to

use

a gravity feed system then conversion to a two pipe system

must

be

carried

out, this is explained

on

page

7.

A filter of the metal bowl type

with

a micronic filter element

must

be fitted

in

the

oil

supply

line.

A valve

must

not

be

fitted

on

the

oil return pipe, if this

pipe

should

become blocked it

may

cause the

The installer MUST

supply

and

fit a fire check valve in

and

this valve

must

comply

with

BS

Two Pipe System

Where

it

is

not

possible to install a gravity oil

supply

system

then a two

pipe

pumped

system

must

be

installed. The oil

in

this

arrangement

is

drawn

from the

tank

by

the

pump

on

the burner,

and any

excess is

returned

via

the

second

pipe

to

the

tank

If a

two

pipe

system

is to

be

fitted,

the

pump

on

the

burner

will require to

be

modified from

that

supplied

(See Burner Manual).

The

diagrammatic

layout

of

the

pipe

work

for a

two

pipe

system is

shown

below. Where

the

tank is

below

the level of

the

oil

pump

the

two

pipes

should

each

be

the

same

length

into

the

oil. If

the

return

pipe

is shorter

than

the

flow,

then

it will

be

necessary to fit a

spring

loaded

non-return

valve to this pipe.

On a two

pipe

system

the

pump

vacuum

should

not

exceed 0.4

bar

(30cm Hg). If this is

not

observed

then

dissolved gas will

be

released from

the

oil resulting

in

oil starvation

to

the

burner

and

repeated boiler 'lockouts'.

A filter

of

the

metal

bowl

type

with

a micronic filter

should

be

installed

in

the oil

return

pipe. If

this

pipe

should

become blocked it

may

cause

the

pump

to fail.

The installer MUST

supply

and

fit a fire check valve

in

the

oil

supply

line,

and

this valve

must

comply

with

BS

799:

part

5:

of

length

of

tank

(1/4

inch

per

foot length). This is to

ensure

that

any

impurities

do

not

contaminate the oil

feed. The customer should be

shown

how

to remove these impurities

from time to time,

or

this should

be

carried

out

at

its service

or

maintenance check.

Connections

on

the oil

Air Supply

Conventional Flue

For a conventional flue boiler, air is required, not only for combustion,

but

also for ventilation,

and where the boiler is located in a compartment

or

cupboard additional ventilation is required.

The

volume

of

air required is 550mm

2

jkW

of

boiler output. The requirements for the Jetstreme

4+

range

of

boilers are given below.

existing brick chimney, a stainless steel flue liner

should

be

used

and

the cavity

between

the liner

and

the brickwork

should

be insulated

with

vermiculite

or

similar.

The first section(s) from the boiler

to

within the brick chimney

should

be

of twin wall flue pipe.

COMMISSIONING

Combustion - The responsibilities of

the

commissioning engineer are clearly stated

in

British

Standard 5410

part

1:

1971

and

these responsibilities

must

be

adhered

to.

It

is important that the boiler is commissioned

by

a competent engineer

with

an

understanding

of

the technology

and

with

the

equipment suitable to enable

him

to carry

out

the tests to set the

appliance

at

its

optimum

efficiency

and

with

clean combustion.

It

is strongly recommended

that

an

OFTEC (Oil Firing Technical Association for the Petroleum

Industry) registered engineer is

used

for this purpose. If difficulty is found locating

an

engineer

then

contact can

be

made

through OFTEC

on

telephone

number

01737-373311.

Electrical - Checks for electrical safety should be carried

out

by a competent electrician

with

a

working knowledge of

the

current

IEE

Regulations.

Fuel - Bleed all the air from

the

oil

supply

line to ensure

an

uninterrupted

supply

of

oil to the

burner. This can

be

achieved

on

gravity systems

by

loosening the suction line connection.

It

is

essential

that

any

oil spillage is contained

and

the area

be

cleane~

on

completion.

On a two

pipe

system purging can

be

carried

out

by

running

the oil

burner

and

resetting after lockout.

Water - Ensure that the system is full of water

and

that all air is bled from the radiators

and

boiler. After firing

and

checking that the system is free of water leaks

and

is working satisfactorily

it

is

recommended

that a suitable

anti-corrosion

additive

is

introduced

into

the

system

(e.g.

Fernox). This is

done

by partly draining

down

the system,

putting

in

the additive

and

then

topping

up

with fresh water.

13

First Firing

1.

Ensure

that

the Boiler thermostat

and

the limit thermostat phials are located in their respective

phial pockets

and

are fully home.

2.

Turn

ON

any

isolating taps in the oil

supply

line.

3.

Switch

ON

the

mains electricity isolating switch.

4.

Set

the

programmer

I time clock,

if

fitted, to

an

'ON'

position for

both

CH

and

HW.

5.

Set the

room

thermostat to its

maximum

position.

6.

Set the cylinder thermostat to its

maximum

position.

7.

Turn boiler thermostat to its

maximum

position. -

At

this point

the

burner

will start to

run

and

a

series of clicks will

be

heard as the ignitor attempts to fire the oil.

If

the oil fires satisfactorily the

burner

noise will be heard.

If

the oil fails to ignite, the

burner

will

go

to lockout mode. A red

light will

show

on

the

control panel

to

indicate lockout.

Turn

the

boiler thermostat

on

the control

panel

to the OFF position

and

wait 30 seconds.

Press the

manual

reset

button

on

the burner,

if

the lockout is reset then this

button

will remain

in,

and

the

lockout light will extinguish.

Again

turn

the

thermostat

to

its

maximum

position

to

repeat

the

ignition

sequence.

This

sometimes has to

be

repeated

several times before getting ignition, particularly

with

two

pipe

systems.

Once

the

flame has been established allow

the

burner

to continue to

run

for approximately

10

minutes

before

turning

off the boiler thermostat,

and

inspecting for water

or

oil leaks.

It

may

also

be

necessary to again bleed the system.
Once satisfied that the system is again sealed, remove

the

combustion test point screw from

the

flue spigot

and

insert the sample probe of the test equipment. Turn

on

the

boiler thermostat,

and

carry

out

the combustion tests, referring to

the

information given

in

the

appropriate

tables (see

tables 8-10). All

burners

used

on

the Jetstreme 4+ are factory set

at

a pressure of approximately

20

p.s.i. below

that

required for

maximum

rated output. The oil pressure

and

the

combustion level

must

be

verified

by

on

site testing,

and

adjustments

made

where necessary. Information regarding

the

methods

of

burner

adjustments are explained in the

burner

technical booklet

supplied

with

these instructions.

IMPORTANT

To

ensure that the appliance is covered

by

the 2 year guarantee

the

installation

details

section

of

these

instructions

and

the

warranty card should

be

completed. The warranty card must

be

returned to

Benson

Heating

within

the registration period

of

28 days.

This

does

not affect the statutory rights

of

the purchaser.

programmer

is of a compact

advanced

design

that

can be

programmed

to

vary

for the

Hot

Water

and

Central

Heating

independently

of

each

other

on

fully

pumped

systems,

but

on

work

in

conjunction

with

the

hot

times. The operating times for

Saturday

and

Sunday

can be set to different times to those

of

the

weekdays.

To

set

the

refer

to

the

programmer

section

of

these

instructions (pages 26-29).

Boiler

Thermostat

- This

controls

the

temperature

of

the

water

leaving

the

boiler

to

be

circu.lated

around

the system. The boiler

must

not

be

run

for-

long

periods

with

the boiler

thermostat

set

at

the

low

end

of

the

range.

This

creates

condensation

within

the

combustion

chamber

which

over

time

will

damage

the

interior

surface.

For

the

most

efficient

use

of

the

system

the

boiler

thermostat

should

be

set

at

the

higher

end

of

the

range. Radiators are designed for flows of approximately 80°C

with

an 11°C differential to

the return.

Limit

Thermostat

- This is a safety device

that

switches off the boiler

in

the case of a failure

in

the boiler thermostat. This

can

be reset

by

pressing

in

the

button

located

on

the

underside

of

the

control

panel

upwards

where

it

should

be

retained.

Should

this limit

thermostat

repeatedly operate

then

you

should

consult

your

engineer.

Green

Neon

- This only illuminates

when

the Burner is

in

its

operating

mode.

Red

Neon

- This is only illuminated

when a burner

fault develops

and

the

lockout procedure

occurs. (Also the lockout

button

on

the

burner

control box will illuminate)

both

lights will

remain

on

until

the

burner

is reset

or

mains electricity to the appliance is disconnected.

24

Lockout

The Lockout condition is a built

in

safety device which comes into operation

when

the

burner

controls suspect

or

register

that

a fault

has

developed

that

could cause

damage

to the burner.
Several things can create this situation such as:­Oil tank allowed to

run

out

of fuel.

The valves

in

the oil line have been turned off.
The fire check valve has operated.
Air

in

the

supply

pipe;

usually

caused

by

allowing the

tank

to

run

dry,

then

on

refilling

not

bleeding the air from the

supply

pipe.
Wrong grade of fuel supplied.
Water contamination of the oil tank, this

is

quite common where the inspection doors

or

vent caps
etc. have been left open.
Faulty

or

contaminated filter causing blockage to the

burner

nozzle.

No

ignition at the

burner

nozzle

due

to

burner

fault.

In

most cases it is recommended that a qualified service engineer is employed

to

correct the

fault.

Lockout Reset

If

the boiler goes to lockout condition, this is indicated

by

the illumination of the

RED

NEON

on

the control panel.

To

reset the

burner

the following procedure should be followed:-

1.

Remove the lower front panel.

2.

On

the

burner

control box a glowing

red

button

will

be

noticed. This is the Lockout Reset

Button.

3.

Turn the boiler thermostat to the OFF position.

4.

Press the Lockout Reset Button fully horne.

5.

Release the Lockout Reset Button. The light will go

out

and

should remain so.

6.

Turn the boiler thermostat to the required setting. The ignition .cycle should then automatically

commence.

7.

If

Lockout continues to re-occur

then

a competent engineer should be consulted. Do

not

attempt

to adjust the

burner

or

its controls.

Note:

If

the oil storage tank has been allowed

to

become

empty

then air

may

be present

in

the

supply

pipe. The oil

supply

pipe

will require either 'bleeding' ifit is a

one

pipe system

or

the

continued resetting of the lockout to clear the air

on a two

pipe system.

It

is always useful to

consult

your

installer as to which system is fitted.

25

Under

these terms, Benson Heating will

bear

the cost of replacement parts,
