SEALANTS, ADHESIVES AND PAINTS
Sealants, Adhesives and Paints are used in the construction of
Boilers. When used in the manner for which they are intended
they do not present any known hazard.
ELECTRICELECTRIC
ELECTRICELECTRIC
ELECTRIC
All Boilers when in use have electrical supply of 240V (enough
to endanger life) connected to the Panel and Burner.
Always isolate the boilers during cleaning, servicing and repair.
EXTERNAL BOILERS
In wet weather conditions due consideration should be given to
the metal casing and electrical current within the Boiler casing.
Never open the front door of External Wall Mounted Boilers in
conditions such that water could come in contact with any
electrical component causing an immediate danger to life.
Health and Safety at Work Act 1974
Consumer Protection Act 1987
COSHH Regulations 1988
The following information is given as a requirement of the above
legislation.
Great care is taken by Thermeco Boilers to ensure that Boilers
are designed and manufactured to meet general safety
requirements when properly used and installed as
recommended in this manual.
It is the responsibility of Users and Engineers to ensure that
adequate protective clothing and glasses are worn when working
on the Boiler.
FUELFUEL

FUEL
KEROSINE GAS & OIL FUELS (MINERAL OILS)
1. The effect of minerals oils on the skin vary according to the
duration of exposure.
2. The lighter fractions also remove the protective grease
normally present on the surface of the skin rendering the
skin dry, liable to crack and more prone to damage caused
by cuts and abrasions.
3. Skin rashes (oil Acne). Immediately seek medical attention
for any rash, wart or sore developing on any part of the body,
particularly on the scrotum.
4. As far as possible avoid any skin contact with mineral oil or
clothing contaminated with mineral oil.
5. Never breathe any mineral oil vapours. Do not fire the
Burner in the open i.e. out of the Boiler as misfire will cause
unburnt oil vapours.
6. Barrier cream containing lanolin such as Rosalex Antisolv,
is highly recommended together with a strict routine of
personal cleansing.
7. Under no circumstances should mineral oils be taken
internally - never suck or blow a pipe!

2-1 Control Box Internal Boilers
2-1.1 Boiler Thermostat Control
The Boiler Thermostat Control is used to control the temperature of the water within the
Boiler Water Chamber.
The temperature range of the control is 60°C to 90°C. The recommended settings of the
Boiler Thermostat control are:-
Winter Heater and Hot Water 80°C - Summer Hot Water only 65°C.
2-1.2 High Limit Thermostat with Manual Reset
A High Limit Thermostat with an integral Manual Reset button is fitted as standard to all
internal condensing Boilers. Boilers fitted with Manual Reset High Limit Thermostats will
not restart automatically after overheating has occurred.
The High Limit Thermostat will trip and shut the Boiler down when the water within the
Boiler is overheated.
When the water temperature falls to a satisfactory level (10°C below High Limit
Thermostat setting), the Manual Reset button (protected by a removable plastic cap)
should be pressed - this will restart the Boiler.
If overheating occurs check that the Boiler Heating Thermostat control is set at 80°C or
below. If it still occurs more than occasionally, consult your installation engineer as there
may be a fault within the system.

3-3 Burner ‘Lockout’
The burner has its own control system that synchronises the burner ignition sequences.
The safety system of the burner includes a flame detector (photoresistor) which senses
the light of the flame.
In the event of a failure of the flame, the burner control goes through a re-ignition
sequence. If the flame is not evident within 15 seconds, the burner shuts down due to its
lockout circuit being energised.
The reset lamp in the burner beset button illuminates to indicate that ‘lockout’ has
occurred.

To set Boiler for operation:-
3-1.1 Boiler Operation
The Boiler Thermostat switches power to the burner ON and OFF in response to the
temperature of the water within the Heat Exchanger.
The burner will automatically fire when the water temperature within the Boiler falls below
the thermostat control setting, and will continue to run until the water temperature rises to
the set °C.
The burner has its own Control System that gives correct ignition and shut-off sequences
to maintain safe operation.
3-1.2 Automatic Boiler Operation
A fully automatic central heating and hot water installation with its own remote timer and
control system will switch the Boiler ON and OFF as and when heat is required.
Note
The Installer should instruct the user on
operating the central heating system.
3-2 Switching the Boiler OFF
The Boiler can be switched off by any of the following means:-
1. Switch the Mains Switch on the Boiler Control Panel to OFF (external only).
2. Turn the Boiler Thermostat control to STOP.
3. Switch OFF the mains switch controlling the Boiler.
4. Set the central heating control system to OFF.
IMPORTANT In the event of abnormal operation:-
1. Switch OFF the mains switch controlling the Boiler.
2. Shut OFF fuel supply.
3. Refer to Section 10 Fault Finding.
Note
For frost protection of External Wall
Mounted and External Freestanding Boilers
the mains switch controlling the Boiler must
be ON.

In the event of a ‘lockout’, wait 45 seconds and restart the burner by pressing the reset
button.
If lockouts are more than occasional, consult your service engineer as there may be a
fault with the fuel supply or burner.
3-3.1 Restart Boiler after ‘Lockout’
Lockouts indicate a fault in the Boiler operation and can be attributed to:-
1. An interruption in the fuel supply (most common).
2. A fault in the electrical supply i.e. very low voltage.
3. Faulty operation of the burner or its safety control system.
4. A component failure.
5. A fault in heating system control external to Boiler.
Before attempting to restart the Boiler, remove the front panel of the Boiler and look for any
obvious problems i.e. oil leaks.
Restart Procedure:-
1. Check that there is sufficient oil in the tank and that the supply valves are open.
2. Check that the Boiler thermostat, time switch or programmer and any other system
controls are set to call for heat.
3. Press and release the red glowing plunger reset button on the burner control box.
The red light will extinguish and the burner will commence the start sequence.
After 15 seconds, the burner should fire normally.
If the burner does not fire, the lockout symptoms will persist and the burner control box
reset button will again glow.
4. Wait at least 45 seconds and press the lockout button on the control box again.
IMPORTANT If the Boiler fails to start on the second attempt then:-
Switch off the Electricity Supply.
Refer to Section 10 Fault Finding.
DO NOT ATTEMPT TO START MORE THAN TWICE.
3-4 Care of the Boiler
3-4.1 All Internal Boilers
Occasionally wipe the casing down with a non-abrasive cleaner and vacuum out dust and
cobwebs from within the casing.
3-4.2 External Wall Mounted Boilers
Occasionally wipe the casing down with a non-abrasive cleaner and vacuum out dust and
cobwebs from within the casing.
Regular application of car polish to the outside of the casing will help protect the paint
finish and prevent algae growth.
3-4.3 Servicing
Condensing Boilers require servicing once a year to ensure continued reliable operation
and fuel economy. Servicing at the stated intervals is a prerequisite of the Boiler
Warranty.
A competent engineer should be sought to carry out the servicing at the required intervals.
An OFTEC trained and registered engineer would be a good choice.
IMPORTANT Ensure that the
condensate drain pipe is kept clear
and able to drain away freely.

ALLATION GENERAL 4TION GENERAL 4
TION GENERAL 4TION GENERAL 4
TION GENERAL 4
The Boiler and heating system must be installed to comply with the latest Building
Regulations, British Standards and OFTEC recommendations, refer to the Appendix at the
back of this book.
4-2 Siting and Positioning the Boiler
4:2.1 Considerations for Boiler Position
The most suitable position for the Boiler is usually dictated by the flue arrangement, the
location of the flue terminal is restricted by regulations refer to Appendix.
Other consideration will be condensate drain, oil pipe and heating pipework arrangements.
Careful consideration of the most suitable Boiler position should be undertaken before
installation.
4-2.2 Noise Levels
Quiet operation is a design feature of Themeco Boilers making them ideal for kitchen and
utility room installations. However, consideration should be given to the noise levels of the
Boiler and the following:-
1. Sound levels must be discussed with the householder as some individuals are
particularly sensitive to even low levels of noise.
2. The type and position of the flu may affect noise levels.
3. Conventional flues are generally noisier than balanced flues.
4. Noise from balanced flues facing neighbouring properties should be considered.
5. Sound levels in small rooms may appear more intrusive than the same sound
pressure in a larger room.
6. Some building materials can tend to amplify the sound from Wall Mounted Boilers,
using battens to space the Boiler off the wall may reduce this effect.
4-2.3 The Hearth - Floor Standing
The hearth temperature of Select and Option Boilers is less than 85°C. A suitable level
hearth, which is impervious to kerosine, must be provided.
Where the Boiler is to stand on a floor of combustible material then protection between the
Boiler and the floor should be provided by means of non-combustible material.
The floor must give adequate support to the filled Boiler. Consult the Building Regulations
for safe floor loadings.
4-2.4 Frost Protection
The Boiler and the central heating system must be protected from frost.
External Free Standing Boilers have a frost thermostat fitted as standard, this must be
correctly wired to provide frost protection - see wiring diagrams Section 11.
All Boilers installed in outhouses or where conditions of frost could arise must be
protected by a frost protection arrangement that will fire the Burner when the temperature
falls below 4°C.
A suitable antifreeze must also be used in applications where freezing can occur and
should be considered for all systems.
4-2.5 Rodent Intrusion
Boilers installed in situations where rodent intrusion is possible, all pipe/cable entry holes
of the Boiler must be covered, after installation, to prevent rodents entering the Boiler
casing.
Note
For Boiler Weight see Section 11.

The Boiler must be commissioned
within 10 working days of installation,
failure to do so will invalidate the
Guarantee.
