Euroflame Oil Boilers

The boiler will provide domestic hot water and central
heating and is fully automatic once switched on. An
illuminated On/Off switch, see Fig. A, is fitted to the
Euroflame Kitchen/Utility model, which lights when the
boiler is switched on, but does not necessarily indicate the
burner is firing.

To access the Kitchen/Utility model controls, pull the
front panel off (push-on fixings).

1 Ensure that - There is sufficient fuel, of the correct

type, in the supply tank and all fuel supply valves are
open. The water supply is on. The electricity supply
to the boiler is off. The boiler On/Off switch is set to
OFF (Kitchen/Utility models, the neon in the switch is
not alight). The room thermostat (if fitted) is at the
desired setting. The boiler thermostat is set to the
required setting (see section 1.7).

2 Switch on the electricity supply to the boiler.

Note: Boiler House models will light at this stage.

3 For Kitchen/Utility models, set the On/Off switch to

ON. A neon in the switch lights when it is in the on
position.

The boiler will now light automatically.

Euroflame Oil Boilers

Kitchen/Utility models for short periods - Set the On/
Off to OFF.
To restart, simply set the switch to ON.

Kitchen/Utility models for long periods: Set the On/Off
switch to OFF and switch off the electricity supply to the
boiler. If required, the fuel supply valve may be closed and
the water and electricity supplies turned off at the mains.
To restart, refer to the full lighting instructions above.

Boiler House models for short periods - Switch off the
electricity supply to the boiler.
To restart, switch on the electricity supply to the boiler.

Boiler House models for long periods - Switch off the
electricity supply to the boiler. If required the fuel supply
valve may be closed and the water and electricity supplies
turned off at the mains.
To restart, refer to the full lighting instructions given
previously.

1 Check that the boiler On/Off switch is ON.
2 Check that any remote programmer (if fitted) is

working and is in an 'on' period.

3 Check that all thermostats are set to the desired setting

and are calling for heat.

4 Check if the burner 'Lock-out' reset button is lit. If it is,

press it to start the burner. If the burner fails to light and
goes to 'Lock-out' again, check that you have sufficient
fuel in the storage tank and that the fuel supply valve is
open.

5 Ensure that a fuse has not blown or that the electricity

supply has not failed.

6 Check to see if the safety thermostat has operated (see

section 1.7).

If the burner still fails to light after carrying out these
checks then a fault exists. Switch off the electricity supply
to the boiler and contact your Service engineer.

Euroflame boilers will operate on either Class C2 Kerosene
or Class D Gas Oil. Your Installer will have informed you of
the type of fuel your boiler has been set to use and he will
have marked this on the boiler data label. You should always
quote the type of fuel you require when ordering from your
supplier.

Note: Balanced flue models (flue terminal through the
wall) must only be used with Kerosene.

Do not wait until the fuel runs out before you order some
more. Sludge in the bottom of the tank may be drawn into
the fuel lines. If it is possible, switch off the boiler when
the new supply is delivered and leave the fuel to settle for
an hour before restarting the boiler.

1 Boiler thermostat - This control allows the

temperature of the water leaving the boiler to heat the
radiators and domestic hot water to be adjusted.

Note: If you have a cylinder thermostat on your hot
water cylinder, this will control the temperature of
your domestic hot water. The boiler thermostat setting
must be equal to or above the cylinder thermostat
setting to enable the cylinder thermostat to control the
domestic hot water system.

The boiler thermostat has an operating range of 65 to
85°C. The following settings are recommended:­a Heating and hot water in Winter 85°C
b Hot water only in Summer 65°C

2 Burner Lock-out reset button - If there is a burner

malfunction, a built-in safety circuit switches the
burner off and the Lock-out reset button will light.
Usually such malfunctions are short lived and
pressing the reset button will restore normal
operation.

If the burner continually goes to 'Lock-out' a fault
exists or the fuel supply is low. If you have sufficient
fuel, you will need to call your Service engineer.

3 Safety thermostat - Your boiler is fitted with a safety

overheat thermostat which will automatically switch
off the boiler in the case of a control malfunction
causing overheating.

If your boiler goes off and you try to light it but nothing
happens and the 'Lock-out' reset button on the burner is
not lit, the overheat thermostat has probably operated.
The boiler will not light until the thermostat is reset. To
reset, unscrew the small plastic cap (see Fig. 30a or 30b),
press the button then replace the cap.

If this condition continually repeats, contact your
Service engineer.

4 Ventilation - Always ensure that the boiler has

adequate ventilation. Any ventilation openings
provided by the Installer must not be obstructed.
Periodically check that they are clear.

Do not attempt to 'box in' the boiler or build a
compartment around it before consulting your
Installer.

Do not place any combustible material around or on
the boiler or flue pipe.

5 Flue terminal - The flue terminal on the outside wall

must not be obstructed or damaged.

In severe conditions check that the terminal does not
become blocked by snow.

6 Frost protection - Your Installer may have fitted a

frost thermostat. If not, and you are likely to be away
for a short time, leave the boiler on with the boiler
thermostat set at a low setting. For longer periods the
boiler and system should be drained. Contact your
Service engineer for draining and filling the system.

7 Cleaning and servicing - Lightly wipe over the case

with a damp cloth and a little detergent. Do not use
abrasive pads or cleaners.

You should have your boiler serviced at least once a
year to ensure safe and efficient operation. Contact
your Service engineer for further details.

8 Failure of electricity supply - If the electricity

supply fails, the boiler will not operate. It should
relight automatically when the supply is restored.

If a programmer is fitted (Multi Pass Kitchen models
only) it will retain the time settings for up to 24 hours
and will not have to be reset to the correct time of day
when the supply is restored (the display remains for
up to 1 hour, but will re-appear when the supply is
restored).

The boiler requires a 230/240 V ~ 50 Hz supply. It must
be protected by a 5 Amp fuse.

Warning: This appliance must be earthed.

If your boiler is operating on a sealed heating system, the
installer will have pressurised the system and should have
told you (or set it on the pressure gauge) the system
pressure when cold (this is normally between 0.8 and 1.0
bar, which will increase slightly when hot). If the pressure
(when cold) is below the set pressure mentioned above,
you should contact your Installer or Service engineer to
re-pressurise the system. If the system requires frequent
re-pressuring, ask your Installer or Service engineer to
check the heating system for leaks.

The boiler or system will be fitted with an automatic air
vent to remove air from the system. Any air trapped in the
radiators should be removed by venting the radiators
using the vent screw at the top of each radiator. Only vent
a radiator if the top is cool and the bottom is hot.
Excessive venting will reduce the system pressure, so
only vent when necessary and check the system pressure
as mentioned above. Re-pressurise the system if
necessary.

Note: Your system may incorporate a 'Top-Up' vessel,
advice on how to use it should be obtained from your
installer.

The boiler or system will be fitted with a safety valve to
release excess pressure from the system. If water or steam
is emitted from the end of the safety valve discharge pipe,
switch off the boiler and contact your Installer or Service
engineer.

The expansion vessel air charge must be checked
annually. Failure to maintain an adequate air charge
in the vessel may invalidate the warranty.

3.4.1 Fuel storage

A painted (outside only) storage tank must be
constructed to BS 799:5:1987 and should include the
following:-

a A fuel level gauge (not a glass type).
b A vent pipe incorporating a weatherproof

termination (bend or cap) of a diameter not less

than the filling pipe.
c A sludge valve.
d An outlet valve at the opposite end of the tank

to the sludge valve.

The tank should be positioned in accordance with the
recommendations given in BS 5410:1:1997, which
gives details of filling, maintenance and protection
from fire.

The tank should be suitably supported so as to obtain a
slope of 20 mm per metre towards the sludge valve.

A galvanised tank must not be used.
A plastic tank may be used and must comply with OFS

T100.
Note: Plastic tanks should be adequately and

uniformly supported on a smooth level surface, across
their entire base area.

3.4.2 Fuel pipes

1 Fuel supply pipes should be of copper tubing with

an internal diameter of at least 8 mm.
Soldered joints should not be used.
Galvanised pipe must not be used.

2 Flexible pipes must not be used outside the boiler case.
3 A remote sensing fire valve must be installed in the

fuel supply line (outside) where it enters the
building, with the sensing head located above the
burner. Recommendations are given in BS
5410:1:1997.

4 A metal bowl type filter with a replaceable

micronic filter must be fitted in the fuel supply line
adjacent to the boiler. A shut-off valve should be
fitted before the filter, to allow the filter to be
serviced.

5 A flexible fuel line, adaptor and 1/4" BSP isolation

valve are supplied loose with the boiler for the final
connection to the burner. If a two pipe system or Tiger
Loop system is used, an additional flexible fuel line
(900 mm) and 3/8" to 1/4" BSP male adaptor are
available from Grant Engineering (UK) Limited.

6 Flexible fuel lines should be inspected annually

when the boiler is serviced and replaced every two
years.

7 The use of a 'Tankmaster' and Tiger Loop is an

ideal way of delivering an oil supply to the boiler.
The Tankmaster unit, fitted to the storage tank,
includes a filter, sight tube, shut-off valve and fire
valve. A separate fire valve is required in the fuel
line (outside) where it enters the building
containing the boiler. See Fig. 4.

3.4.3 Single pipe system - (See Fig. 2)

1 Where the storage tank outlet is above the burner

the single pipe system should be used. The height
of the tank above the burner limits the length of
pipe run from the tank to the burner.

2 As supplied the burner is suitable for a single pipe

system.

3.4.4 Two pipe system - (See Fig. 3)

1 When the storage tank outlet is below the burner,

the two pipe system should be used. The pipe runs
should be as shown in Fig. 3. The return pipe
should be at the same level in the tank as the
supply pipe, both being 75 to 100 mm above the
base of the tank. The pipe ends should be a
sufficient distance apart so as to prevent any
sediment disturbed by the return entering the
supply pipe.

2 Avoid the bottom of the tank being more than 3 m

below the burner.

3 A non-return valve should be fitted in the supply

pipe together with the filter and fire valve. The
return pipe must be unrestricted.

4 To be used with a two-pipe system, the burner

must be fitted with an additional flexible fuel line
(a flexible fuel line (900 mm) and 3/8" to 1/4" BSP
male adaptor are available from Grant Engineering
(UK) Limited). See section 3.4.6.

5 The pump vacuum should not exceed 0.4 bar.

Beyond this limit gas is released from the oil.

1 When The storage tank is below the burner, an

alternative to a two pipe system can be achieved using
the Tiger Loop oil deaerator. This effectively removes
the air from the oil supply on a single pipe lift.

2 The Tiger Loop is connected close to the boiler as

a two pipe system (omitting the non-return valve)
as shown in Fig. 4. Refer to the manufacturers
instructions supplied with the Tiger Loop.
The Tiger Loop must be mounted vertically.

Note: To prevent any possibility of fuel fumes
entering the building, the Tiger Loop must be
fitted outside.

section 4.6.

1 A 230/240 V ~ 50 Hz mains supply is required.

The boiler must be earthed.

2 The supply must be fused at 5 Amp and there must

only be one common isolator for the boiler and
control system, and it must provide complete
electrical isolation.

3 A fused double pole switch or a fused three pin

plug and shuttered outlet socket should be used for
the connection.

4 The power supply cable should be at least 0.75 mm²

PVC as specified in BS 6500, Table 16.

5 All the wiring external to the boiler must be in

accordance with the current I.E.E. Wiring
Regulations.

6 Any room thermostat or frost thermostat used must

be suitable for use on mains voltage.

7 In the event of an electrical fault after installation

of the boiler, the following electrical system checks
must be carried out:- Short circuit, Polarity, Earth
continuity and Resistance to earth.

See Figs. 7 and 8

A sufficient permanent air supply to the boiler should be
provided:

a For proper combustion of fuel and effective discharge

of combustion products to the open air.

b For the ventilation of any confined space in which

the boiler is installed to prevent overheating of the
boiler any equipment in and near the boiler.

c For the satisfactory operation of any draught

stabiliser which may be fitted.

It should be both the designer's and installer's concern
that the air required for these functions be introduced so
as to cause as little discomfort as possible to the building
occupants and thus to offer them the least temptation to
obstruct the ventilators.

Further details may be obtained from BS 5410:1:1997.

Notes:

For a boiler fitted in a compartment, which is
ventilated as shown, no additional allowance is
necessary.

Open flue - Extract fans, where needed, should

Grant boilers have high operating efficiencies. Care
must be taken to ensure the flue system is suitable for
the low flue gas temperatures.

1 An insulated flue terminating in a down draught

free area, i.e. at least 600 mm above the point of
exit through the roof or preferably above the ridge
level, will normally provide the necessary draught
of at least 8.7 N/m2 (0.035 in wg) as measured close
to the boiler connection. If a draught of 37 N/m

2

(0.15 in wg) or more is measured, then a draught
stabiliser should be fitted in the flue.

2 The flue terminal must be at least 600 mm from

any opening into the building, and 600 mm above
any vertical structure or wall less than a horizontal
distance of 750 mm from the terminal. See Fig. 10.

3 If an existing chimney is used, it must be lined with

a stainless steel liner for use with fuel oil. The top
and bottom of the annular space must be sealed and
the void filled with a suitable insulating material to
reduce cooling of the flue gases.

4 If a rigid flue is used either internally or externally, it

must be of the twin wall type with a stainless steel
inner skin suitably insulated and weather proofed.

5 The flue diameter must be as specified in

section 2.1 for the size of boiler in question.

6 The flue must be run upwards following as near a

vertical route as possible. Horizontal runs must be
avoided and no bends should have an angle of more than
45° from the vertical. There should be at least 600 mm
of vertical flue above the boiler before the first bend.

7 A sealed cleaning door must be provided near the

base of the flue.

8 The exposed flue pipe between the boiler and the

chimney must not be of an asbestos material and
aluminium must not be used in any part of the flue.

9 If the draught conditions are satisfactory, the flue

should terminate with a standard cowl suitable for
pressure jet oil boilers. Where the flue cannot
terminate above the ridge of the roof, use an 'OH'
or similar type cowl where downdraughting occurs.
Ridge vent terminals must not be used.

10 Refer to the locally applicable Building

Regulations, BS 5410:1 and OFTEC Installation
Requirements (Books 2 and 3) for further guidance
on conventional flue systems.

11 To allow for flue gas analysis and combustion

testing, a test point is provided in the cleaning
cover. Alternatively, a test hole can be drilled in
the flue pipe.

prevent objects entering the flue pipe.

20

Euroflame Oil Boilers

For additional protection of either the entire heating
system, or the boiler and localised pipework, it is
recommended that a frost thermostat be installed.
Refer to section 8 for connection details.

To protect the heating system the frost thermostat
should be sited within the house in such a place that it
can detect any rise and fall in the ambient air
temperature, i.e. in a room with a radiator.

Where the frost thermostat is installed outside the
house (to protect a boiler installed in an external boiler
room or garage) or in an attic, it is recommended that
it be used in conjunction with a pipe thermostat to
avoid unnecessary and wasteful overheating of the
property. The pipe thermostat should be located on the
boiler return pipe, and set to operate at 25°C. Refer to
section 8 for connection details.

1 The boiler must stand on a surface that is firm and

level. It does not require a special hearth as the

temperature of the boiler base is less than 50°C.
2 Sufficient clearance must be allowed around the

boiler for the following:-

Access above the boiler to remove the baffles for

servicing.

Access at the front of the boiler to remove the

burner.
3 If the boiler is to be installed with a side against a

wall, allow a nominal clearance of 20 mm for the

plugs for the water connections. Water connections

may be taken from one side only if required (see

section 3.12, paragraph 2).

Kitchen/Utility and Boiler House - See Fig. 11

1 A high level flow and low level return connection

are provided on each side of the boiler. See Fig. 1.

1" BSP connections are used on 50/70, 70/90

models and 1¼" on 90/120 models.
2 Flow and return connections should preferably be

diagonally opposed, i.e. to opposite sides of the

boiler. If the boiler is to be positioned against a

wall, the water connections may be taken from one

side only.
3 All models have a tapping (½" BSP) on the front

for the thermostat pocket, (pocket supplied loose

with Boiler House models).

4 All water connections have been temporarily sealed

with plastic caps to prevent any residual water
(from factory testing) leaking from the boiler
during transit. All the caps must be removed before
connecting any fittings.

Plug all unused connections.

5 Fit drain taps in the central heating and domestic

hot water systems to allow the complete system to
be fully drained.

6 Thoroughly flush the system before fitting the pump.

System boiler

The system pipework may exit the boiler from either the
left hand or right side of the boiler casing. See Fig. 1.

1 Fit any elbows, bushes etc. to the heating return

tapping at the bottom (1" BSP 50/90 or 1¼" BSP
90/120) before placing the boiler in position if
access is restricted. Do not forget to plug the
unused connection on the opposite side.

2 The heating flow pipe (22 mm 50/90 or 28 mm 90/120)

and 15 mm safety valve discharge pipe are provided
with pushfit Tectite elbows to enable quick and simple
installation. Orientate the elbows for left or right hand
connection. Ensure that the installation pipework is
pushed fully home into the elbows.

The 90/120 boiler is supplied with a 28mm flow pipe
factory fitted for left hand side exit. A 28mm push fit
Tectite elbow is provided for easy connection of the
heating system pipework.
If required, the flow pipe may exit through the right
hand side panel. The 28mm factory fitted flow pipe
must be turned 90° and routed across the boiler
behind the control panel.

Important: Care must be taken not to obstruct
the cleaning cover door on top of the boiler as
removal of the door and the boiler baffles will
not be possible.

3 The safety valve discharge pipe must be routed clear

of the boiler to the outside, to discharge in such a
manner that the discharge can be seen but cannot
cause injury or damage to persons or property.

4 The cold fill shut off valve should be fitted in an

accessible position close to the boiler to enable
connection of the temporary flexible filling loop to
the boiler.

1 The boiler is suitable only for use with a sealed

system complying with the requirements of BS

5449.

The maximum temperature of the central heating

water is 85°C.
2 The boiler is supplied with the following items

factory fitted:-

a A diaphragm expansion vessel complying with

BS 4814, pre-charged at 1.0 bar.

b System pressure gauge, with an operating range

of 1 to 4 bar.

c Pressure relief safety valve complying with BS

6759 and set to operate at 3 bar.
d Circulating pump with isolating valves.
e Automatic air vent.
f Filling loop. This must be isolated and

disconnected after filling the system.

3 The central heating system volume, using the

expansion vessel as supplied, must not exceed the
volume shown in section 2.1. For further guidance
refer to BS 7074:1.

Refer to section 4.14 for further details of the
expansion vessel.

4 The system design pressure (cold) should be

between 0.5 and 1.0 bar. This pressure is
equivalent to the maximum static head (see Fig.

14) in bar + 0.3 (1 bar = 10.2 metres of water).

5 If thermostatic radiator valves are fitted to all

radiators, a system by-pass must be fitted.

6 Provision should be made to replace water lost

from the system. This may be done manually
(where allowed by the local Water Undertaking)
using the filling loop arrangement supplied with the
boiler.

3 - GENERAL BOILER INFORMATION

23

Euroflame Oil Boilers

7 Filling of the system must be carried out in a

manner approved by the local Water Undertaking.
Where allowed, the system may be filled via the
filling loop supplied (the loop arrangement
includes a double check valve assembly).

8 All fittings used in the system must be able to

withstand pressures up to 3 bar.

9 Radiator valves must comply with the requirements

of BS 2767(10):1972.

10 One or more drain taps (to BS 2879) must be used

to allow the system to be completely drained.

To avoid the danger of dirt and foreign matter entering

the boiler the complete heating system should be

thoroughly flushed out - before the boiler is connected

and then again after the system has been heated and is

still hot. This is especially important where the boiler is

used on an old system.

For optimum performance after installation, this boiler

and its associated central heating system must be flushed

in accordance with the guidelines given in BS 7593:1992

'Treatment of water in domestic hot water central heating

systems'.

This must involve the use of a proprietary cleaner, such

as BetzDearborn's Sentinel X300 or X400, or Fernox

Superfloc. Full instructions are supplied with the

products, but for immediate information, please contact

BetzDearborn on 0151 4209563 or Fernox on 0179

9550811.

For Long term protection against corrosion and scale,

after flushing, it is recommended that an inhibitor such as

Betzdearborn's Sentinel X100 or Fernox MB01 or Copal

is dosed in accordance with the guidelines given in BS

7593:1992.

Failure to implement the guidelines may invalidate the

warranty.

3.13.4 Underfloor heating system - (See Fig. 15)

On underfloor systems it is essential that the return is

pre-heated by mixing flow water into the return before

it enters the boiler. The return temperature must be

maintained above 55³C to prevent internal corrosion of

the boiler water jacket.

Refer to section 3.8 to fit a conventional flue.

See Figs 16 and 17

If the boiler is to be used with a balanced flue, decide
upon the position of the boiler and determine exactly
where the flue will pass through the wall.

Check that there are no obstructions in the way, that
the terminal position complies with the dimensions
given in Fig. 10 and then make the hole in the wall for
the flue as shown in Fig. 16 (low level flue) or Fig. 17
(high level flue).

Note: The hole dimensions given in Figs. 16 and 17
include an extra 10 mm over the size of the terminal to
provide clearance for fitting.

Note: When the boiler is installed with the back panel
against the wall and a high level flue, the throat of the
flue bend could enter the inner wall opening. Cut away
the underside of the hole in the inner wall to accept the

See Fig. 6

If a two pipe system is to be used refer to section 3.4.8.
1 Remove the plug from the fuel pump oil inlet

adaptor and connect the elbow of the flexible fuel
line supplied with the boiler.

2 Connect the flexible fuel line to the rigid supply

using the adaptor supplied. For Kitchen/Utility
models the supply enters through one of the holes
at the bottom of the case sides or the back panel.

Expansion vessel pressure

The expansion vessel fitted is supplied with a
charge pressure of 1.0 bar (equivalent to a max.
static head of 10.2 metres). The charge pressure
must not be less than the actual static head at the
point of connection (see Fig. 14). Do not pressurise
the vessel above 1.5 bar.

The air pressure in the vessel must be checked annually.
The central heating system volume, using the

expansion vessel as supplied, must not exceed 107
litres. If the system volume is greater, an extra
expansion vessel (complying with BS 4841) must be
fitted as close as possible to the central heating return
connection on the boiler. The charge pressure of the
extra vessel must be the same as the vessel fitted in the
boiler. Refer to BS 7074:1 for further guidance.

The air charge pressure may be checked using a tyre
pressure gauge on the expansion vessel Schraeder valve.
The vessel may be re-pressurised using a suitable pump.
When checking the air pressure the water in the heating
system must be cold and the system pressure reduced to
zero.

A simple test to check if the expansion vessel size is
adequate, is to fill the system cold to 1.0 bar, then fully
heat the system and if the pressure rises no more than 2.0
bar the vessel is adequate. A higher figure indicates that
an extra vessel is required.

Fill the system

1 An automatic air vent is fitted to the top of the

boiler (see Fig. 20). Check that the small cap on the
top of the air vent is screwed on fully, then unscrew
it one complete turn - the cap remains in this
position from now on.

2 Ensure that any valves in the heating system

pipework are open.

Connect the fuel supply

4.6

Fill and vent a sealed system

4.7

28

Euroflame Oil Boilers

3 Ensure that the flexible filling loop is fitted between

the shut off valve on the mains water supply and the
double check valve on the heating system.

4 Open the mains shut off valve and then gradually

open the valve on the double check valve until
water is heard to flow. The valves are fully open
when the operating lever is in line with the valve
body and closed when it is at right angles to it.

5 Fill the system until the pressure gauge indicates a

pressure of approximately 1.5 bar. Close both the
filling loop valves and check the system for water
soundness, rectifying where necessary.

6 Vent each radiator in turn, starting with the lowest

in the system, to remove the air.

7 It is important that the circulating pump is properly

vented to avoid it running dry and damaging its
bearings. Undo the cover in the centre of the pump,
insert a suitable screwdriver into the end of the
pump shaft and rotate it at least one complete turn.
Replace the plug.

4 - BOILER INSTALLATION

8 Check the operation of the safety valve (see Fig.

20) by turning the head anticlockwise until it
clicks. The click is the safety valve lifting off its
seat allowing water to escape from the system.
Check that this is actually happening, and water
flows unobstructed from the relief discharge pipe.

9 Continue to fill the system until the pressure gauge

indicates 1.0 bar. Close the filling valve and cold
water inlet valve and check the boiler and system
for water soundness, rectifying where necessary.
Water may be released from the system by
manually operating the safety valve until the
system design pressure is obtained.

10 The system design pressure (cold) should be

between 0.5 and 1.0 bar. This pressure is
equivalent to the maximum static head in bar + 0.3
(1 bar = 10.2 metres of water). See Fig. 14.
Set the adjustable pointer on the pressure gauge to
the system design pressure.

11 On completion of filling, ensure that both filling loop

valves are closed and disconnect the flexible hose.

Refer to Figs. 21 or 22 for boiler controls

It is important that the following commissioning
procedure is carried out to ensure safe and efficient
operation of the boiler.
If the boiler output is to be adjusted from that
which is factory, set refer to section 1.2 or 1.3 for
the required settings, section 7.4 for burner head/
nozzle change instructions and Fig. 24 for baffle
adjustment as appropriate.

Note: Check that the baffles are in position and
that the cleaning cover is correctly fitted and a
good seal made.

1 Check that the water system has been vented (and

pressurised if sealed system) and there are no leaks.
2 Check that all fuel line valves are open.
3 Remove the plastic burner cover (two screws) if it

was not previously removed.
4 Connect a combined vent manifold and pressure

gauge to the pressure gauge connection port on the oil

pump. See Fig. 19. Open the vent screw on your vent

manifold to vent the supply while the pump is running.
5 Set the boiler On/Off switch to Off (Kitchen/Utility

models only). Check that all system controls are

calling for heat and turn the boiler thermostat to

maximum. Switch on the electricity supply.

Note: Boiler House models will start as soon as the
electricity supply to the boiler is switched on.

6 Set the boiler On/Off switch to On (Kitchen/Utility

models only). The burner fan should start and the
burner should light within about 20 seconds. If the
burner does not light and the 'Lock-out' reset button
lights, wait for about 45 seconds then press the
reset button to restart the ignition process. This
procedure may have to be repeated several times
during first lighting.

5 - COMMISSIONING

7 With the burner alight, check the fuel pressure.

Refer to the Technical Information, sections 2.2
and 2.3. Adjust the pressure if necessary - see Fig.

19. Note that the On/Off switch (Kitchen/Utility
models only, see Fig. 30a) lights when the boiler is
switched on, but does not necessarily indicate the
burner is firing.

8 Operate the boiler until it reaches normal operating

temperature. Check oil pipes for leaks, rectifying
where necessary.

9 With the burner alight, re-check the fuel pressure and

re-adjust if necessary. Turn the boiler off, remove the
pressure gauge and replace the plug in the pump.

10 Having ensured that there are no oil leaks, replace the

burner cover. Ensure the flexible air tube is connected
to the burner (balanced flue models).

11 Relight the boiler and allow it to run for 20 minutes

then check the following:­CO2 level, Flue gas temperature and Smoke

Number. Refer to the Technical Information in
sections 2.2 and 2.3.
A flue gas sampling test point is provided on the top
of the boiler.

12 Check the smoke number, if satisfactory check the

CO2. Use the hexagonal key supplied to adjust the
burner air damper (see Fig. 19) as required.
Turning the screw anti-clockwise closes the
damper and increases CO2 level, turning the screw
clockwise opens the damper and reduces CO2 level.

Re-check the smoke number if the air damper has
been moved.
Under no circumstances must the smoke number be
above 1.
A suitable position for the air damper is one which
gives 1% less CO2 than that which has a smoke
number of 1.

Note: It is important that the air damper is
correctly set.

13 Check the flue gas temperature.
14 Check the boiler overheat thermostat by removing

the boiler thermostat phial (the shorter one for
Kitchen/Utility models) from the pocket in the
front of the boiler shell. The boiler should switch
off on the overheat thermostat. Replace the phial.
Unscrew and remove the reset button cover, press
the reset button and replace the cover.

15 When the boiler has been adjusted and is running

satisfactorily, balance the central heating system by
adjusting the radiator lock shield valves. Start with
the radiator nearest the boiler and adjust the valves
to achieve the required temperature drop across
each radiator.
If thermostatic radiator valves have been installed,

check the system by-pass.
16 Switch off the boiler.
17 With the hot water system hot, check again for leaks,

rectifying where necessary. Drain the system while it

is hot to complete the flushing process. Refill and vent

(and pressurise if a sealed system) the system.
18 A suitable central heating system inhibitor must be

added to protect the system against the effect of

corrosion.
19 Replace the case top and front panel as appropriate.

Note: After commissioning the boiler you should
complete the Commissioning Report on page 2 of
these instructions.

If the boiler is to be left in service with the User, set
the controls and room thermostat (if fitted) to the
User's requirements then refer to section 6.
If the boiler is not to be handed over immediately,
close the boiler fuel supply valve and switch off the
electricity supply.
If there is any possibility of the boiler being left during
frost conditions, then the boiler and system should be
drained.

IMPORTANT NOTE:

To allow the boiler to be commissioned and serviced
correctly a combustion test point is provided on the top of
the boiler.

The CO2, flue gas temperature and smoke test may all be
carried out using this test point. The test point is not
suitable for measuring boiler efficiency or conventional
flue draught.

When using the test point on the top of the boiler note
that the flue gas temperature reading will be higher than
that measured in the flue thus resulting in an inaccurate
efficiency reading. To obtain an accurate flue gas
temperature and efficiency, the reading can only be
measured outside through the low level flue terminal. For
high level and vertical balanced flues the reading may be
taked from the flue kit test point provided . Refer to
section 2.2 and 2.3.

For Conventional flue draught measurement and
efficiency a hole must be drilled in the conventional flue
pipe. Seal the hole after testing.

11 - HEALTH AND SAFETY INFORMATION

Under the Consumer Protection Act 1987 and Section 6 of the Health & Safety at Work Act 1974, we are required to
provide information on substances hazardous to health (COSHH Regulations 1988).
Adhesives, sealants and paints used in the manufacture of the product are cured and present no known hazards when used in
the manner for which they are intended.
The following other materials are present in the product:

Insulation materials

Material Types: Ceramic fibre board, mineral wool.
Description: Rigid board, slabs, sleeves, gaskets, ropes.
Known Hazards: May cause temporary irritation or rash to skin. High dust levels may irritate eyes and upper respiratory

system.

Precautions: Avoid unnecessary or rough handling, or harsh abrasion of boards. Normal handling and use of material

should not produce high dust levels.
Avoid inhalation, and contact with skin and eyes.
After handling always follow normal good hygiene practices.

Protection: Use disposable gloves, face mask and eye protection.
First Aid: Eyes - If irritation occurs, wash eyes with copious amounts of water. If symptoms persist, seek immediate

medical advice.
Skin - If irritation occurs, wash under running water before washing with soap and water.
Inhalation - Remove to fresh air, drink water to clear throat and blow nose to remove dust/fibres.
Ingestion - Drink plenty of water.

Sealants

Material Types: Silicone elastomer.
Description: Sealant and adhesive.
Known Hazards: Irritation to eyes.
Precautions: Avoid inhalation of vapour, contact with eyes and prolonged or repeated contact with skin.

After handling always follow normal good hygiene practices.

Protection: Use eye protection. Rubber or plastic gloves should be worn where repeated contact occurs and a face

mask worn when working in confined spaces.

First Aid: Eyes - Flush eyes with water for 15 minutes. Seek immediate medical attention.

Skin - Wipe off and wash with soap and water.
Inhalation - Remove to fresh air.

Kerosene and Gas oil fuels (Mineral oils)

Known Hazards: The effect of mineral oils on the skin vary according to the duration of exposure and the type of oil.

The lighter fractions remove the protective grease naturally present on the skin, leaving it dry, liable to
crack and more prone to damage by cuts, abrasions and irritant chemicals.
Skin rashes (Oil acne) most often on arms, but also on any part of the body in contact with oil or oily
clothing.
Contact with fuel oils can cause dermatitus.

Precautions: Avoid as far as possible any skin contact with mineral oil or with clothing contaminated with mineral oil.

The use of a lanolin-based barrier cream is recommended, in conjunction with regular washing with soap
and rinsing with water to ensure all oil is removed from the skin.
Take care to prevent clothing, especially underwear, from becoming contaminated with oil.
Do not put oily rags or tools in pockets, especially trouser pockets.
Have first-aid treatment at once for an injury, however slight.
Do not inhale any vapours from mineral oils.
