Normal Pressure
Requires
Repressurising
3.1 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 (Fig. 1).
3. A pressure of 3 or greater indicates a fault. The safety
pressure relief valve will operate, at a pressure of 3 (Fig. 3). 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. 2). Error Code E119 will be shown on the
display.
3.2 To Re-Pressurise the System
1. Look at the boiler from underneath. There will be two taps,
one connected to the cold inlet valve and one to the central
heating return valve. Do not operate these taps yet !
2. Your installer will have left a short copper pipe with wing
nuts (the ‘filling loop’) with you for safe keeping.
3. To re-pressurise this loop MUST be connected to the taps.
Remove the blanking caps from each tap and set aside.
4. Ensure that the two seals are fitted, and connect the loop to
the taps with the wing nuts. These should be hand tightened.
5. Carefully open both taps and check the boiler pressure
gauge. Once the needle on the gauge is above the 0.5 mark
both taps can be closed.
6. Undo the two wing nuts, remove the loop and refit the
blanking caps. Put the loop in a safe place for future use, and
ensure that the seals remain in place

1. This appliance must have been installed in accordance
with the manufacturer’s instructions and the regulations
in force.
2. Any modification that may interfere with the normal
operation of the appliance without express written
permission from the manufacturer or his agent could
invalidate the appliance warranty. In GB this could also
infringe the Gas Safety (Installation and Use) Regulations.
3. Your boiler must not be operated without the casing
correctly fitted.
4. Do not interfere with any sealed components on this
boiler.
5. Take note of any warning labels on your boiler.
6. Your boiler should have the following minimum
clearances for Safety and Maintenance
(Fig. 4):-
Top - 200mm
Bottom - 150mm*
Left side - 5mm
Right Side - 5mm
Front - 5mm (In Operation)
- 450mm (For Servicing)
*This is the MINIMUM recommended dimension.
Greater clearance than this will aid installation and
maintenance.
7. If your boiler is installed in a compartment, do not use
it for storage purposes. Do not obstruct any purpose
provided ventilation openings.
8. Flammable materials must not be stored in close
proximity to your boiler.
9. Avoid skin contact when your boiler is in operation, as
some surfaces may get hot e.g. pipework.
10. Ensure that the flue terminal, outside the house,
does not become damaged or obstructed, particularly
by foliage.
11. It is important that the condensate drain system is
not blocked, modified or damaged in any way as this
would affect the operation of your boiler. Your installer
should have insulated any exposed pipework.

5.0 Care of the Boiler
8© Baxi Heating UK Ltd 2010
5.1 Cleaning the Outer case
The painted panels should be wiped with a damp cloth and
then dried completely. DO NOT USE ABRASIVE
CLEANING AGENTS.
5.2 Protection & Precaution
1. The boiler incorporates an integral frost protection feature
that will operate in both modes. If the boiler temperature falls
below 5° C, then the boiler will operate until the water
temperature has been raised.
2. If a system frost thermostat has been fitted (your installer
will be able to advise you), then to operate correctly and
protect your system, the gas and electricity must be left on and
the appliance set in the central heating mode.
3. The boiler incorporates an integral pump protection feature
which continually monitors the time since the pump last
operated. To prevent seizure, the pump will operate for
approximately 1 minute if it has not run in the last 24 hours.
5.3 Fault Indication
1. If a fault occurs on the boiler an error code may be shown
on the facia display (Fig. 5).
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.

7.0 Setting the Timer
10 © Baxi Heating UK Ltd 2010
7.1 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. 6)
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.
0Off (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 anti-clockwise.
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. 7).
NOTE: The integral timer may have been removed and
replaced with a blanking plate depending on the type of
external controls used. In this event please consult your
installer for details.
