1.1 Operating the Boiler
The Central Heating and Hot Water you need will be
available when the gas and electricity supplies to the boiler
are turned on with the timer and other heating controls in
your system set correctly.
Other heating controls are items such as room
thermostats, cylinder thermostats and thermostatic
radiator valves. To give the most energy efficient
performance these controls can switch your boiler
on and off even when your timer is on. Instructions
on how to use your programmer and other
heating controls should have been supplied with
the items. Baxi Heating UK Limited also produce a
guide ‘How to get the best out of your NEW
Central Heating System’. Telephone our Literature
Hotline on 08706 060 623 to request your free
copy.
1. Ensure that the electricity and gas supplies are turned on.
Check that the central heating pressure is at least 0.5 bar
(Fig. 1).
2. Turn the On/Off/Reset selector switch either anticlockwise from the OFF position (Fig. 3) to both central
heating and domestic hot water or clockwise to domestic
hot water only.
3. In either position the display will illuminate showing the
current boiler temperature in degrees centigrade (Fig. 2).
4. Position (i) Heating and Hot Water (Fig. 4) In this
position the central heating will operate on demand from
the integral timer, room thermostat etc or domestic hot
water will be provided when a tap or shower is turned on.
Priority is given to domestic hot water. The central heating
indicator ( ) will illuminate when the boiler is supplying
central heating. If there is a demand for domestic hot water
the ( ) indicator will illuminate and the central heating
indicator ( ) will extinguish (Fig. 2). As the temperature
rises the display will change, showing the current boiler
output temperature.
5. Position (ii) Hot Water Only (Fig. 5) In this position only
hot water will be provided when a tap or shower is turned
on - Central Heating will not operate. The hot water
indicator ( ) will illuminate (Fig. 2).
6. The boiler will light automatically on demand.
7. The burner on indicator ( ) will illuminate when the
boiler is operating and the main burner has lit (Fig. 2).
IMPORTANT: When the selector switch is in the ‘0’
(Off) position the electrical supply to the boiler is
isolated. The boiler will not operate and the integral
timer will require resetting once the selector switch is
set to either Position (i) or Position (ii).

1.2 Fault Indication
1. If a fault occurs on the boiler an error code may be
shown on the facia display.
2. The codes are either two or three digit, preceded by the
letter 'E'. For example, code E133 will be displayed by 'E1'
alternating with '33'. E50 is shown as 'E' then '50'.
3. E20, E28, E50, E125 & E160 indicate faulty components.
You should make a note of the displayed error code and
contact your installer or service engineer.
4. If E110 or E130 is displayed overheat of the primary
water or flue system has occurred. Turn the selector switch
to the reset position and hold for at least 5 seconds. If the
boiler does not relight, or the code is displayed regularly
contact your installer or service engineer.
5. E119 is displayed when the primary water pressure is less
than 0.5 bar. After repressurising the system the boiler
should operate. Your installer will be able to advise you
about the method of repressurising. See page 6 for further
details.
6. E133 indicates that the gas supply has been interrupted,
ignition has failed or the flame has not been detected.
Ensure that the gas supply has not been turned off, and turn
the selector switch to the reset position and hold for at
least 5 seconds. If the boiler does not relight, or the code is
displayed regularly contact your installer or service engineer.
1.3 Resetting (Fig. 8)
1. To reset the boiler turn the selector switch fully
anticlockwise against the spring pressure for approximately
5 seconds and release.
1.4 Pump Protection
1. With the selector switch in either Position (i) or Position
(ii) (Figs. 7 & 9) the pump will automatically operate for 1
minute in every 24 hours to prevent sticking.
1.5 3-Way Valve - Anti-sticking
1. If there is no demand for heat in a 24 hour period, the 3way valve will be operated once to help prevent sticking.

1.6 Temperature Control
1. Central Heating: The central heating hot water flow
temperature can be adjusted between 25° C minimum
and 80° C maximum.
2. Turn the control knob clockwise to increase the
temperature (Fig. 10). As the control knob is turned the
selected temperature is displayed for approximately 4
seconds. The display then reverts to the current boiler
output temperature.
3. In normal winter usage we recommend that the central
heating temperature be set at maximum.
4. Domestic Hot Water: The temperature of the domestic
hot water can be adjusted by turning the control knob
clockwise to increase up to a maximum of 60° C (Fig. 11).
As the control knob is turned the selected temperature is
displayed for approximately 4 seconds. The display then
reverts to the current boiler output temperature.
5. The temperature of the water is also dependent on the
water flow rate and the temperature of the mains coming
into the house.
6. By slightly reducing the flow from the tap the
temperature will increase up to the maximum if required.
7. The flow rate can be reduced down to as low as 2 litres
per minute. The boiler will still recognise the need to heat
the water.

Pressure Gauge
1.7 Central Heating System Pressure
1. The water pressure in the central heating system is
indicated by the pressure gauge.
2. With the system cold and the boiler not operating the
pressure should be at least 0.5 bar. During operation the
pressure should not exceed 2.5 bar, and will normally be
between 1.0 and 2.0 (Figs. 12 & 13).
3. A pressure of 3 or greater indicates a fault. The safety
pressure relief valve will operate, at a pressure of 3 (Fig.
14). It is important that your Installer or Service Engineer
is contacted as soon as possible.
4. The MINIMUM pressure for correct operation is 0.5. If
the pressure falls below 0.5, this may indicate a leak on the
central heating system (Fig. 15). Error Code E119 will be
shown on the display.
1.8 To Shut Off the Boiler
1. For short periods: Turn the selector switch to the OFF
position (Fig. 16).
2. For long periods: Turn off the selector switch (Fig.16),
electricity and gas supplies.
If your home is to be left unoccupied for long periods
during cold weather the boiler and whole system should
be drained unless there is additional frost protection.
3. Your installer will advise you about frost protection and
draining the system.
IMPORTANT: When the selector switch is in the ‘0’
(Off) position the electrical supply to the boiler is
isolated. The boiler will not operate and the integral
timer will require resetting once the selector switch is
set to either Position (i) or Position (ii).
1.9 Boiler Frost Protection Mode
1. The frost protection feature will operate when the
selector switch is in the central heating and domestic hot
water mode.
The gas and electrical supplies to the boiler must be on and
the system pressure must be within the range described
above.
2. If the system temperature falls below 5°C, then the
boiler will operate until the water temperature has been
raised.

3.0 Timer

3.1 Setting the Timer
The Electro-Mechanical Timer allows the central heating
system to be set every 15 minutes.
Using the three position switch the timer will allow either
constant operation, timed operation or central heating off.
Move the switch button by sliding to the desired position.
Three position switch (Fig. 17)
Constant (Top position): The heating will
be on constantly irrespective of the position
of the tappets.The heating will be controlled
by the main thermostat on the appliance
and/or any external controls.
Timed (Central position): The heating will
operate according to the position of the
tappets and be controlled as above.
0 Off (Bottom position): No central heating.
Domestic hot water will operate on demand.
To set the time of day
Turn the timer outer bezel clockwise, to align the pointer
with the correct time to the nearest 15 minutes
ensuring that A.M./P.M. is considered.
Do not at any time attempt to turn the bezel anticlockwise.
To set the timed heating program
Decide which times of the day the central heating is
required.
The heating will operate when the white tappets are set to
the outer edge of the bezel.
To ensure the heating stays OFF set the required tappets
inwards towards the centre of the bezel.
Each tappet represents 15 minutes.
For example: If the heating is not required between
10 A.M. and 11 A.M. the four tappets anticlockwise from
the 10 A.M. will be set inwards (Fig. 18).
