1 General information
1.1 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.
ecoMAX 8 series 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 automatically adjusts to
meet the demand for both central heating and domestic
hot water in the most economical way.
ecoMAX 6 series provides central heating and
domestic hot water where a separate indirect hot water
cylinder is also incorporated to the system.
The benchmark gas boiler commissioning checklist (in
the installation manual) should be completed by the
installer and/or the commissioning engineer.

4.2.2 Checking the water contents
Fig. B.4 Checking the water contents
• Check the water contents of the system on the pressu-
re 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.
4.3 Domestic hot water operation
The boiler should only be used when the heating system
contains water. Use of the boiler without water may
cause damage to the boiler or its components.
4.3.1 Setting the maximum domestic hot water
temperature control (ecoMAX 8 series only)
Fig. B.5 Domestic hot water operation
• 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 temperature can be adjusted
using the hot water temperature control (3).
• Turn the control clockwise to increase the temperature
and anti-clockwise to decrease the temperature.
Note!
This control adjusts the maximum domestic hot
water temperature. If adjusting the control
upwards appears to have no effect on the tem-
perature, then the boiler is already operating at
full output for the selected flow rate.
Attention!
If you live in a hard water area please do not set
the control knob above the mid (12 o’clock) posi-
tion to prevent excessive scale formation (fig.
B.5).
4.3.2 Warmstart operation (ecoMAX 8 series only)
Fig. B.6 Warmstart operation (ecoMAX 8 series only)
The warmstart facility provides instantaneous delivery of
domestic hot water from the boiler.
When the warmstart system is switched ON the boiler
will automatically light periodically to maintain the inter-
nal temperature of the boiler. When the warmstart
system is switched OFF a short delay may be experien-
ced in obtaining hot water at the tap.
• The warmstart system is activated by turning the hot
water temperature control knob (1) clockwise to positi-
on a (see fig.B.6). Now select the required temperatu-
re, e.g. setting b

water tap is opened.
4.3.3 Obtaining hot water (ecoMAX 8 series only)
Fig. B.7 Obtaining hot water (ecoMAX 8 series only)
On opening a hot water tap (1) fig. B.7) at a supply point
(basin, shower, bath, etc) the ecoMAX 800 series boiler
will automatically operate to deliver hot water.
On closing the tap the boiler switches OFF (or continues
to operate for central heating if required).
The pump and fan will continue to operate for a short
period.
4.4 Heating operation
The boiler should only be used when the heating system
contains water. Use of the boiler without water may
cause damage to the boiler or its components.
Fig. B.8 Setting the maximum radiator temperature control
4.4.1 Setting the maximum radiator temperature
control
• Turn the main switch (1) to the “l” position.
• Set the maximum radiator temperature control to the
desired setting using the control knob (2).
We recommend the following settings:
- Left setting during spring and autumn,
- Middle setting during mild winter,
- Right setting during cold winter.
When the temperature is adjusted, the boiler display will
show the corresponding water temperature. This infor-
mation appears on the display for about 5 seconds and
then the display returns to its normal state (current hea-
ting flow temperature e.g. 5 °C).

4.4.2 Setting the external controls
Fig. B.9 Setting the external controls
• Set the room thermostat and/or the thermostatic
radiator valves according to the instructions supplied
with the control(s).
Note!
Vaillant offer room thermostat/time control
accessories which give accurate and economic
room temperature control as well as improved
comfort.
Ask your installer!
The boiler will now operate automatically to provide cen-
tral heating for the conditions selected on the external
controls (ecoMAX 800 series will also provide domestic
hot water on demand).
Whilst the boiler is operating, the boiler display indicates
the temperature of the water within the boiler circuit.
After the boiler stops operating the pump and fan will
continue to operate for a short period to fully disperse
the heat from the boiler.
Note!
The boiler incorporates an anti-cycling economi-
ser control to prevent energy wasteful ON and
OFF operation of the boiler for short periods
when in the central heating mode. When turning
the room thermostat to a higher setting there
may therefore be a short delay before the boiler
operates.

4.6 Resetting the appliance
Fig. B.11 Resetting the appliance
When a hot water tap (ecoMAX 800 series only) or the
central heating system requires heat, the boiler automa-
tically ignites and starts to operate. If the automatic igni-
tion is not successful within 5 attempts, then the boiler
does not go into operation and switches to “Lock out”.
This is indicated by a fault code “F.28” or “F.29” on the
display.
A new attempt to ignite the flame can then only be per-
formed after pressing the “Reset” button.
• Press the “Reset” button (1) and hold for approx.
1 second.
Attention!
If the boiler still shuts off after a third attempt,
then please consult your installer or Vaillant
Service Solutions.
The boiler also switches to “Fault” when there is not
enough water in the system. This fault is indicated by
fault code “F.22” “F.23” or “F.2 ”.
The boiler can only be placed back in operation after the
heating system has been properly refilled with water.
In the unlikely event of any other fault developing, which
prevents the boiler from operating, the display will also
show other fault codes. If a fault code is displayed please
contact your installer or Vaillant Service Solutions.
Note!
If contacting Vaillant Service Solutions please
remember to quote the fault code, as this will
help to pinpoint the fault.

4.9 Troubleshooting
In the unlikely event that a problem occurs with the ope-
ration of the ecoMAX boiler, the following points should
be checked:
1 Boiler fails to operate:
• Is the gas supply turned on? (see page 5)
• Is the water supply turned on? (see page 5)
• Is there enough water in the heating system? (see
page 6)
• Is the electrical supply switched ON?
• Is the main ON/OFF control in the “ON” position?
(switch position “I”) (see page 6)
• Is the burner lock out indicator light illuminated?
(see page 9)
2 Hot water operates but no central heating
(ecoMAX 8 series only)
• Is the heating turned ON? (see page 7)
• Are all external heating controls ON? (see page 8)
Attention!
If your boiler still does not operate then please
consult your installer or Vaillant Service
Solutions ( 87 6 6 777).
4.1 Care and maintenance
Clean the outer casing of your boiler with a damp cloth
and a little soap. Do not use abrasive or solvent cleaning
agents that may damage the case or the plastic fittings.
The appliance should be serviced at least once per year.
To ensure regular servicing, it is strongly recommended
that arrangements are made with your service agent or
Vaillant Ltd.
For further details please contact Vaillant Service
Solutions: (0870 6060777).
4.11 Frost protection
Your boiler is equipped with a frost protection function:
If the heating water temperature drops below 5 °C when
the main switch is ON, then the boiler goes into operati-
on and heats the boiler circuit to approx. 30 °C.
Note!
It cannot be guaranteed that water will circulate
throughout the entire heating system.
If the boiler is not operated for several hours during
very cold weather there is therefore the possibility of
the system freezing.
Please ensure that if you are absent during a period of
frost the central heating remains in operation and all
rooms are kept above freezing point.
It must be remembered, however, that the boiler will be
automatically switched off by the built in monitoring
devices if certain faults occur, e.g. interruption in the gas
or electricity supply or faults in the flue gas system. To
overcome this possibility you can drain both the central
heating system and boiler.
Note!
Frost protection and monitoring devices can
only function when the main switch of the unit
is set to the “I” position and the boiler is
connected to the electrical supply.
