GENERAL INFORMATION

We can accept no liability

whatsoever for damage or

injury resulting from failure to

observe these instructions.

Key to symbols

Liability

For your information Thank you for choosing a Vaillant

boiler. The information given in this

booklet will enable you to obtain the

best performance from your boiler.

TURBOmax Plus provides both central

heating and domestic hot water,

with the domestic hot water supplied

directly from the boiler. The boiler

will operate automatically to provide

domestic hot water whenever a hot

water tap is opened, and auto-

matically adjusts to meet the demand

for both central heating and domestic

hot water in the most economical way.

THERMOcompact provides central

heating and domestic hot water

where a separate indirect hot water

cylinder is also incorparated to the

system.

If, after reading these instructions,

you have any questions on the

operation of the boiler, please

contact either your installer or Vaillant

Technical Department.

The benchmark logbook should be

completed by the installer and/or the

commissioning engineer and handed

to the user.

All CORGI registered installers

carry a CORGI ID card, and have a

registration number.

Both should be recorded in your

Benchmark Log Book. You can check

your installer by calling CORGI direct

on 01256 372300.

GENERAL INFORMATION

Specified use

EC designation The purpose of EC designation is to

certify that the boiler complies with

the requirements of the directives

covering gasfired appliances

(Council directive 90/396/EEC) and

electromagnetic compatibility

(Council directive 89/336/EEC).

These appliances also comply with

the requirements of the directive on

operating efficiency (Council directive

92/42/EEC).

Vaillant TURBOmax Plus and

THERMOcompact boilers are made

to fulfil the latest technical specifica-

tions and official safety regulations.

These appliances are designed as

boilers for use in central heating and

hot water supply systems.

THERMOcompact boilers only supply

domestic hot water where a separate

indirect hot water cylinder is also

incorparated to the system.

If the appliances are used for purposes

other than or in excess of these

specifications, this shall be classed as

incorrect operation, and neither the

manufacturer nor supplier will accept

any liability for resulting damage or

injury.

Use of this type is entirely at the

owner’s risk.

The term „specified use” also covers

observance of the operating and

installation instructions, along with

adherence to the servicing schedules.

SAFETY

Safety instructions

Setup and adjustments

switches in the hazardous area

ON or OFF.

- Do not smoke in the hazardous

area.

- Turn off the gas supply at the gas

meter.

- Ventilate the room.

- Consult your gas supplier, service

agent or other competent person.

Initial checks before

turning ON

Open the service valves

●Ensure the cold water service valve

is open. This can be checked by

opening a hot water tap and

ensuring water flows.

●Ensure that the service valves in

the heating flow and return (2and

1) and the gas service valve (3)

are open.

☞The flow, return and gas

service valves are open when

the line marking has the same

direction as the pipe.

●The pressure relief valve (4) is

provided for safety reasons and

must not be interfered with.

Note:

A bottom cover is fitted to the

appliance. The service valves can

be seen through the cover.

Indicator lights/boiler display

TURBOmax Plus and THERMOcompact

boilers have an advanced multi-

function boiler display (1). When the

main ON/OFF control is in the „ON“

position the display will normally

show the temperature of water in the

boiler circuit (45 °C in the example),

which confirms that the boiler is

functioning correctly.

1In the unlikely event of a fault

developing which prevents the

boiler from operating, the display

may show a fault code (page 14).

but has no function.

OPERATION

Check the water contents

●Check the water contents of the

system on the pressure gauge (1).

The needle on the pressure gauge

should be within the green band

(between 1 and 1.5 bar). If the

needle displays a value below

0.8 bar when the appliance is

cold, follow the instructions left by

your installer to refill the system.

Alternatively, your installer should

be called to refill the system.

Domestic hot water

operation (TURBOmax

Plus only)

The boiler should only be used

when the heating system con-

tains water. Use of the boiler

without water may cause

damage to the boiler or its

components.

Setting the maximum domestic

hot water temperature control

●Turn the main switch (2) to the „l“

position.

●The display will show the boiler

flow temperature which indicates

electrical power to the boiler.

●The domestic hot water tempera-

ture can be adjusted using the hot

water temperature control (3).

●

Turn the control clockwise to increa-

the temperature and anti-clock-

wise to decrease the temperature.

As a guide for normal circumstances

set the knob to the one o´clock positi-

on.

Note:

This control adjusts the maximum

domestic hot water temperature. If

adjusting the control upwards

appears to have no effect on the

temperature, then the boiler is

already operating at full output for

the selected flow rate.

If you live in a hard water

area please do not set the

control knob above the mid

(12 o´clock) position to prevent

excessiv scale formation

(fig. B.5).
