4. Appliance Details
Overall Size - Height (to hob) 910mm
Width (standard models) 1000mm
Depth (to towel rail) 730mm
Hotplates –340mm diameter x 2

Ovens - Height 270mm
Depth 500mm
Width 345mm
Your cooker is fitted with a thermostatic control device. This operating system provides the
exact heat requirements selected (by the user) for cooking and reduces the overall oil
consumption. The user selects the desired cooking temperature and when the cooker
approaches the selected operating temperature the thermostatic control operates to turn off
the burner flame to maintain a steady temperature. The control knob on the device is marked
which relates to a particular temperature setting of the top oven.
4.1 Using your hotplates
Your appliance has two hotplates, with a joint hotplate in the middle, protected with two
insulated lids which should remain in a closed position when not using the hotplate. The lids
can be raised independently if only using one hot plate. The hot plate temperature is
dependent on the setting of oven temperature. The higher the temperature in the ovens, the
hotter the hotplate will become.
The design of the hot plates is such that the left hand side will become the hottest, making
this suitable for deep fat frying, shallow frying and boiling.
The surfaces of the hotplates are ground flat and it is therefore recommended that all
utensils used have a solid, flat base to come in complete contact with the hot plate for
efficient results.
4.2 Using your Ovens
Your appliance has 2 ovens. The thermostatic dial in the top oven door provides an
indication to the top oven temperatures. This thermometer reading will reduce quite
dramatically when the door is opened and only recover slowly when the door is closed. This
occurrence does not mean that the oven temperature has reduced. The bottom oven is
warmed by the underside of the oven above. Depending on the control device setting and
operational time, this oven will generally operate some 85 –90°C below the top ovens. It
may be used for small food cooking, biscuits, cakes etc but it is best used as a warming
compartment.
4.3 Overheat thermostat
The cooker is protected by an overheat thermostat designed to shut down the burner if a
fault occurs leading to excessive oven temperatures. The overheat thermostat is located
below the control device, inside the lower left compartment. To reset, unscrew the
protective cap and press the button.
NOTE: If overheat reset occurs more than once contact your service technician.

4.4 Cleaning your cooker
CAUTION: Cleaning of the Eco Range Cooker should only be carried out when the
appliance has cooled down.
The Eco Range cooker should be wiped over daily with a damp soapy cloth. The enamel
should then be dried and polished with a soft dry cloth to avoid streaking. Any spillages
should be wiped up immediately to prevent hardening of deposits which would make
removal difficult at a later stage.
The hot plates can be kept clean by using a light suede wire brush and gently scrubbing the
plates, taking care not to damage the surrounding enamel. Spillages inside the ovens can
become carbonised at high temperatures, therefore the ovens should be cleaned at regular
intervals with a stiff brush. The surfaces of the oven are natural, therefore to prevent
oxidation dry all surfaces after cleaning.
4.5 Routine servicing / maintenance
All oil appliances require regular servicing by a qualified technician. It is recommended that
your cooker is serviced at least once a year. This will ensure your cooker remains fully
functional and in a safe condition.
5.0 Delivery and Transport
Your Eco Range Cooker is an extremely heavy and solid appliance. When attempting to
move or transport your cooker please take into consideration these points:
External –In Vehicle –Ensure unit is securely held by ropes and handled carefully by
qualified personnel.
Internal
Remove all objects from your path, including rugs and breakables.
It is often easiest to unhinge a door in the case that it is too narrow, it also stops damage
being applied to the cooker, the property and injuring people.
The plinth on the cooker is strong and sturdy enough to withhold the unit being moved on
rollers, by removing the oven doors you can also create useful handholds.
IMPORTANT:
The top plate is unable to manage the weight of the cooker so should never be moved
or lifted in this way.
Damage can be caused to the cooker and to persons by using inadequate objects to
lever or move the object.
Difficult terrain, including steps, should not be attempted without adequate
manpower and proper precautions.
The supplier of your new ECO Range Cooker can provide you with an authorised engineer
to attend site, strip the appliance and rebuild in the correct location.

The warranty will become invalid if you strip and rebuild the cooker yourself.
5.1 Site Considerations
1. Sufficient space for appliance, so that access for service and maintenance purposes
can be easily attained.
2. Provision of a satisfactory flue/chimney/cowl.
3. A sold non-combustible hearth capable of supporting the appliance.
4. Adjacent to the cooker then should be no combustible walls or surfaces.
5. The cooker must stand against an outside wall so that there is a supply of unrestricted
air to the burner.
6. If the cooker is to be placed within an inglenook, allow a minimum of 1.5 meters
height clearance for comfortable operation.
7. Units and other work tops should be given enough space, allow 25mm for kitchen
units and 10mm for worktops, 3mm should be given for granite and composite stone.
8. The cooker must not be built in, especially the top plate and front plate which must
be removed for maintenance.
6.0 Balanced Flue
A balanced flue allows the cooker to be placed against an outside wall, with either rear or
top outlet concentric flue.
Maximum length of rear flue: 500mm
Maximum length of top outlet flue: 300mm vertical
500mm horizontal
The surrounding area must be taken into consideration, as strong winds may affect flue
performance.
Balanced flue units are supplied with the following components:
1 no. Outer flue pipe 5” (air intake)
1 no. Inner flue pipe 3” (exhaust outlet)
1 no. Flue terminal
1 no. Heatproof silicon
4 no. Stainless steel self-trapping screws
1 no. Oven vent pipe with tee
Instructions for installation:
1. A suitable position for the range must be taken into consideration before attempting
to install or move the appliance. See section 5.1 for site considerations.
2. Mark the positions for the flue and oven vent, it is important to confirm all
measurements by physically measuring the appliance.
3. Push oven vent through hole and manoeuvre cooker into position. After the cooker
has been moved to the correct position, tighten the compression fitting so that there is
a 3/5º drop from appliance to outside termination.
4. Cut the pipes to the correct length.

5. With the supplied tape and silicon make a seal on the inner and outer pipes. Push into
the cooker, whilst making sure no excess sealant has leaked that may block the
cooker spigots. Ensure minimum of 3º drop.
6. With suitable material make a good flue hole.
7. Fit the terminal to the pipes whilst ensuring the inner pipe has adequate clearance
between terminal end and outlet (min. 50 mm). Secure terminal with supplied screws
and heatproof silicon.
8. The oven vent must then be cut to the correct length, solder tee to pipe with outlets
top and bottom. It is vital that there are no bends in the oven vent.

WHAT IS A CONDENSING BOILER AND HOW DOES IT WORK?
On all standard boilers the flue gases that go up the chimney have quite a high temperature (200°C / 260°C)
and are made up of a few different types of gases. A condensing boiler is designed so that these flue gases
pass through a stainless steel heat exchanger connected to the boiler. These flue gases transfer heat to the
water contained in the secondary heat exchanger.
This results in (a) increasing the temperature of the water returning to the main boiler
(b) Converting some of the flue gases into condensate
(c) Lowers the exit flue gas temperatures considerably (Less than 85°C)
This all results in increased efficiency in the boiler and therefore a saving on oil.
IMPORTANT CHANGES TO BOILER MANAGEMENT:
Annual Service –This is very important in order to keep the flue ways clean and ensure the boiler is
correctly set.
Quarterly Check –empty and clean the condensing trap (Fig.4)
Always ensure that the condensate is flowing freely through the outlet into the drain. This can get dirty and
block flow or it can freeze in extreme conditions.
Plume –a condensing boiler, which produces a white plume from the flue into the air. This is caused by the
low flue gas temperatures mixing with the colder air outside.
Best performance:
Radiator Heating System - Flow Temperature 70°C - Return Temperature 50°C
Underfloor Heating System - Flow Temperature 50°C - Return Temperature 40°C
Note: return temperature should never be less than 40°C

BOILER OPERATION
The Boiler Control Thermostat responds to the temperature of the water within the boiler and switches power
to the burner when heat is required.
The burner has an independent control system which regulates the firing and (shut-off) of the burner.
Automatic firing of the burner will occur when the water temperature within the boiler falls below the
control thermostat set point which will continue to run until the water temperature rises to the temperature set
on the boiler control thermostat.
SWITCHING THE BOILER ON
-Check there is water in the system.
-Check radiator valves are on.
-Turn on oil supply.
-Switch electrical supply to the boiler on (including time clock) and then set the boiler control thermostat
to recommend setting.
BOILER CONTROLS
BOILER CONTROL THERMOSTAT
The temperature of the water within the boiler is controlled and maintained by the Boiler Control
Thermostat located on the boiler control panel.
TEMPERATURE SETTINGS:
The Boiler Control Thermostat has a range of 50°C to 80°C. The recommended setting for the boiler control
thermostat is:
WINTER Heating and hot water supply 80°C
SUMMER Domestic hot water supply 65°C
It is not recommended to operate the boiler with a thermostat setting of less than 60°C as this will precipitate
corrosion, thus reducing the life of the boiler.
HIGH LIMIT STAT
The high limit lockout will occur when the water within the boiler is or has overheated e.g. reached a
temperature above that set on the high limit thermostat.
TO RESET THE BOILER
When the boiler has had time to cool, unscrew black cap and press button on the control panel to reset.
LOCKOUT INDICATOR: RED
The lock out indicator will illuminate when the burner has failed to fire, e.g. No fuel or an electrical fault.
Wait for two minutes then press the manual reset button (coloured red –Fig 1) on the control box to reset.

SWITCHING THE BOILER OFF
The boiler can be switched off at anytime using one of the following:
-Turn the boiler control thermostat to the OFF position
-Switch the mains (electrical supply) to OFF
-Set the control system to OFF (e.g. Time Clock)
PLEASE NOTE: For longer periods of shutdown e.g. while away on holiday, switch OFF the mains
(electrical supply) and turn OFF the OIL supply.
If shutdown occurs during cold weather ensure boiler is protected against frost damage.
BURNER LOCKOUT
The burner has an independent control system (Burner Control Box); this includes a flame detector
(Photocell), which senses the presence of a flame. In the event of a flame failure, the burner control box
activates a second re-ignition sequence. Should the photocell not detect a flame presence within 15 seconds
the burner goes to LOCKOUT and shuts down.
Continued LOCKOUTS are a result of a fault in the operation of the boiler and can be attributed to
following examples:
-An interruption of the fuel supply.
-Electrical Supply Fault e.g. Extreme low voltage.
-Failure of a burner component.
-A fault within the heating system.
-Burner combustion not being correct.

The Burner Reset button on the Control Box illuminates to indicate that a lockout has occurred.
In the event of the Burner locking out, do not attempt to restart the Burner by pressing the Reset Button on
the Burner Control Box for at least 2 minutes. A Bi-metallic timer within the Control Box has a minimum
cooling time of 45 seconds thus the 2 minute interval will ensure that this Bi-metallic timer has cooled and is
therefore in a position where it may be reset.
RESTARTING AFTER LOCKOUT
When lockout has occurred, inspect for any obvious causes e.g. oil leaks. Also check the fuel line from the
tank to the boiler and that any oil shut off valve has not been inadvertently closed.
RESTART
-Check there is adequate oil in the storage tank.
-Check oil supply valves are open
-Switch on heating system (e.g. Time Clock)
-Press the Burner Reset Button on the burner Control Box, which will be illuminated. The Burner Reset
Button (illuminated)(Fig 1) will go out and the burner will commence the ignition start sequence. After
15 seconds the Burner should fire normally.
PLEASE NOTE: Should the Burner not start, the lockout indicator, on the Control Box/Burner Reset
Button will illuminate again.
- Wait at least 3 minutes and press the Burner Reset Button again.
Failure to start a second time indicates a fault requiring attention.
In the event of a second failure to start:
-Switch off electrical supply
-Call service engineer.
REGULATIONS
The installation of oil-fired boilers should comply with the following standards and codes of practice:
- BS5449 Forced circulation hot water heating systems for domestic use.
- BS5410-Part 1Oil installations up to 45kw
- BS7593 Water treatment of hot water central heating systems
- BS7671 Electrical Regulations
- Building Regulations Part 1L and J 2002 England and Wales, Part F Scottish Regulations and
Technical Booklet L Northern Ireland.
- OFTEC Codes of Practice Published or Recommended.
After installing, the system needs to be flushed with a cleanser like Fernox Heavy Duty Restore, for fast-
acting removal of lime scale, black sludge (magnetite) and other deposits from the boiler and the central
heating system. Then add a Fernox protector to give long-term protection of the central heating system
against internal corrosion lime scale formation.

WATER CONNECTIONS
Only two connections for the heating and hot water system on a standard condensing boiler:
1. Flow from top of boiler (Fig.2) and return to top of stainless steel heat exchanger (Fig.2).
2. The PVC pipe (fig 3) is 21.5mm Ǿ and should continue from the condensate trap in side the boiler
casing, which should be plumbed to an external source ensuring one of the following options:
- Internal waste drainage system - Soil/vent stack
- External Drainage system - External condensate absorption point
NOTE: condensate pipe work must fall at least 50mm per metre towards the outlet ensuring all joints are
leak proof.
WARNING: the condensate trap must be filled with water prior to starting the boiler to stop flue gases
escaping
BOILER LOCATION
Sound levels should be discussed with the householder, as some people may be sensitive to low noise levels
in a small room, as is may appear more annoying than in larger rooms. Please Note installation should take
into account of flue position (see diagram).

RECOMMENDED FLUE POSITION

OIL SUPPLY

A flexible oil pipe is supplied to connect the burner to the incoming oil supply pipe.
IMPORTANT NOTES:
-If sitting oil tank above burner height, use single supply pipe only.
