bar

Fig. 3

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 1.5 (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

(Using Temporary Filling Loop)

1. It may be necessary to repressurise the system occasionally

(when the water pressure falls below 0.5 bar). A filling device

(filling loop) will be fitted on the system. This will be on the

boiler itself if the device supplied with the boiler has been used,

or on pipework near to the boiler if another device has been

used.

2. If the water pressure requires regular re-pressurising a fault or

leak is indicated (see section 3.1). Seek advice from your

installer.

3. The filling loop supplied with the boiler consists of two blue

handled isolating taps and a separate temporary filling pipe with

connection fittings (Fig. 3b).

4. Looking underneath the right hand side of the boiler, ensure

the two blue handled isolating taps are in the OFF position.

Remove the Blanking Caps (Fig. 3a).

5. Fit the temporary Filling Loop Pipe, ensuring that the flanged

washers are fitted to both ends of the pipe (Fig. 3b). Tighten the

two wing nuts on the pipe to the taps.

6. Fully open one of the blue tap handles first, and then while

watching the pressure gauge, carefully open the second blue tap

handle (Fig. 3c).

7. When the needle on the pressure gauge indicates between 1

and 2 bar, turn both taps off.

8. The temporary filling loop pipe must be disconnected and

completely removed after the system is pressurised. (Ensure the

two blue handled isolating taps are in the OFF position before

disconnecting.) Keep the pipe in a safe place.

9. Refit and hand tighten the blanking caps previously removed

(Fig. 3a).

NOTE: Only qualified persons are authorised to

assemble, install and maintain the installation.

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.

GB - Heating Industry definition meaning England, Scotland,

Wales, Northern Ireland, Isle of Man and the Channel Isles.

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 - 175mm

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 2015

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. E28 may also

indicate a blocked flue or condensate drain.

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

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.
