1 BOILER CLEARANCES
INTRODUCTION
It is essential that the instructions in this booklet are strictly
followed, for safe and economical operation of the boiler.
Current Gas Safety (Installation & Use)
Regulations or rules in force.
In your own interest, and that of safety, it is the law that this boiler
must be installed by a CORGI registered installer or in IE a
competent person, in accordance with the above regulations.
Electricity Supply
This appliance must be efficiently earthed.
Supply: 230 V ~ 50 Hz. The fusing should be 3A.
Connection must be made in a way that allows complete
isolation of the electrical supply such as a double pole switch
having a 3mm (1/8") contact separation in both poles, or a plug
and socket, serving only the boiler and system controls. The
means of isolation must be accessible to the user after
installation.
IMPORTANT NOTES
a. If the boiler is installed in a compartment then the
compartment MUST NOT be used for storage purposes.
b. The ventilation provided for the boiler during installation
MUST NOT be blocked, and a check should be made
periodically that the ventilation areas are free from any
obstruction.
c. If it is known or suspected that a fault exists on the boiler then
it MUST NOT be used until the fault has been corrected by a
CORGI registered installer or in IE a competent person.
d. Inflammable materials must not be placed in close proximity
to the appliance. Materials giving off flammable vapours
must not be stored in the same room as the appliance.
e. Under NO circumstances should any of the sealed
components on this appliance be used incorrectly or
tampered with.
TTB Downdraught Thermostat
(CF boilers only)
This appliance is fitted with a TTB downdraught thermostat for
added safety and protection. If this thermostat should operate
and switch off the appliance it is because the flue is subject to
downdraught, probably as a result of adverse wind conditions.
The TTB is an automatic reset thermostat which will reset once
wind conditions have returned to normal, subject to a built-in
reset delay in excess of 10 minutes.
The TTB is an IMPORTANT SAFETY DEVICE and MUST NOT be
put out of action or interfered with in any way.
The TTB is not a substitute for an independently mounted
carbon monoxide detector.
In cases of repeated or continuous shutdown a CORGI
registered person or in IE a competent person should be called
to investigate and rectify the condition causing this. Only the
manufacturer's original parts should be used for replacement.
Minimum Clearances
A clearance of 533mm (21") MUST be available at the front of the
boiler for servicing.
The minimum clearances given in Table 1 MUST be complied
with, in order to maintain the safe running of the boiler.
CAUTION. To avoid the possibility of injury during the installation, servicing or cleaning of
this appliance care should be taken when handling edges of sheet steel components

To Light the Boiler Refer to Frame 2
If a programmer is fitted refer to separate instructions for the
programmer before continuing.
1. Check that the electricity supply to the boiler is OFF.
2. Open the control panel drop-down door and ensure that the
thermostat knob (A) is in the OFF position.
3. Switch ON the electricity supply to the boiler and check that
all external controls, e.g. room thermostat etc., are ON.
4. Set the boiler thermostat knob (A) to position 6. The pilot
solenoid valve should open and the intermittent spark
commence, continuing until the pilot is established. The
main burner will then cross-light smoothly.
Winter conditions (i.e. central heating and domestic hot
water). The thermostat should be positioned at setting 5 or 6.
Summer conditions (i.e. domestic hot water only). The
thermostat should be positioned at setting 2.
These settings are offered for general guidance only and other
settings may be found preferable, dependent upon the type of
system installed or as recommended by the installer.
To Shut Down the Boiler
1. For short periods
Turn the boiler thermostat knob (A) to OFF. When heating is
again required, restore the knob to its original setting.
2. For longer periods
a. Turn the boiler thermostat knob (A) to OFF.
b. Switch the electricity supply to OFF.
Frost Protection
If no frost protection is provided and frost is likely during a short
absence from home, leave the heating controls (if fitted) at a
reduced temperature setting.
For longer periods, the entire system should be drained -
including the domestic water supply.
If the system includes a frost thermostat then, during cold
weather, the boiler should be turned OFF at the time switch (if
fitted) ONLY. The mains supply should be left switched ON, with
the boiler thermostat left in the normal running position.
Control of Water Temperature
1. Set the boiler thermostat knob (A) to give the required
temperature for central heating.
2. The boiler thermostat automatically switches the boiler OFF
and ON to maintain the selected temperature.
To Relight the Boiler
Repeat the procedure 1 - 4 detailed in 'To light the boiler'.
Boiler Overheat Thermostat
The boiler is fitted with a safety 'cutout' thermostat: this
thermostat will shut down the boiler in the event of overheating.
Should this occur turn off the boiler and consult a CORGI
registered installer or in IE a competent person.
Loss of System Water Pressure
(Boilers fitted with the Overheat Thermostat Kit only)
If the red arrow on the system pressure gauge is set above zero
and the system pressure is seen to fall below this value over a
period of time then a water leak is indicated. In this event a
CORGI registered installer or in IE a competent person should
be consulted.
DO NOT FIRE THE BOILER IF THE PRESSURE HAS
REDUCED TO ZERO FROM THE ORIGINAL SETTING
Escape of Gas
Should a gas leak or fault be suspected, contact your gas
supplier without delay.
Do NOT search for gas leaks with a naked flame.
Cleaning
For normal cleaning simply dust with a dry cloth.
To remove stubborn marks and stains, wipe with a damp cloth
and finish off with a dry cloth.
Do NOT use abrasive cleaning materials.
Maintenance
The appliance should be serviced at least once a year by a
CORGI registered installer or in IE a competent person.
Note.
The appliance model is given on the data plate, located on the
front of the boiler base plate, behind the grille assembly.

POINTS FOR THE BOILER USER
Note. In line with our current warranty policy we would ask that you check through the following guide to identify any
problems external to the boiler prior to requesting a service engineers visit. Should the problem be found to be other than
with the appliance we reserve the right to levy a charge for the visit, or for any pre-arranged visit where access is not gained
by the engineer.
TROUBLESHOOTING - TYPICAL NON PRODUCT FAULTS
Problem Solution
Boiler is not working for
central heating or hot water.
• Check boiler thermostat (G) is turned up.
• Check the overheat thermostat reset button (J) by holding button in for 2 seconds and then
releasing.
• If fitted to a sealed system check the pressure gauge on the system, this should read a
minimum of 1 bar. If necessary re-pressurise the system via the filling loop. Press the
overheat thermostat reset button (J). If the boiler still does not fire or if the pressure continues
to drop after refilling contact the installer.
• Has there previously been a smell of fumes from the flue ? It is likely that the downdraught
thermostat has operated due to the combustion gases not being evacuated from the flue.
Contact your installer to check the flue is operating correctly and not blocked etc.
Boiler goes through ignition
sequence but fails to light in
either mode.
• Check gas supply (try at another gas appliance cooker/fire etc) If no gas supply then this is not
a boiler fault – contact your gas supplier.
Boiler is operating
satisfactorily for domestic hot
water but will not operate for
central heating.
• If an external programmer is fitted check that the central heating channel is at an ‘on’ period.
• Check that the room thermostat is set at the required temperature. Test the room thermostat
by turning this fully up – if this does not respond contact your installer.
Boiler is operating
satisfactorily for central
heating but will not operate
for domestic hot water.
• If an external programmer is fitted check that the domestic hot water channel is at an ‘on’
period.
• Check that the domestic hot water cylinder thermostat is set at the required temperature. Test
the cylinder thermostat by turning this fully up – if this does not respond contact your installer.
Boiler will not fire the pilot
light is lit but the igniter
continues to spark and the
main burner does not ignite.
• This is a symptom of crossed polarity i.e. the live and neutral supply to the boiler are crossed
over. This is not a boiler fault contact your installer to correct the wiring.
