Please keep these instructions in the spedal pocket provided
in the boiler front panel (5, page 20). In this way they will
always be handy for future reference. /
Thank you for choosing the Vaillont TURBOmax combination boiler. The
information given in this booklet will enable you to obtain the best
performance from the boiler.
The TURBOmox 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.
Because the TURBOmax operates at ahigh'effeciency, a plume of water
vapour may be visible at the flue terminal in cold weather. This is quite
normal and shows that the boiler is operating correctly. .
If, after reading these instructions, you have any questions onthe operation
of the boiler, please contact either your installer or Vaillant Technical
Department.

Initial checks before turning the boiler on
Check supply pipes
Ensure cold water shut off valve @ is open (this con be checked by opening 0 hot top
and ensuring water flows). Also check that both the flow and return central heating
service valves CD and ® and the gas service valve (j) are open: (The flow, return
and gas service valves are open when the line marking is in the some direction os the
pipe).
The pressure relief valve ® is provided for safety reasons and must not be interfered
with. .

; . ~~

Check water contents
Open the lower door by pulling outwards. Check the water contents of the system. The
white hand on the lower scale of the pressure and temperature gauge ® should be
between 1 and 1.5 bar. j(the hand is below O.B·bar when the system is cold, your
installer should be called to refill the system. .
The top scale of the pressure and temperature gauge shows the temperature of water in
the central heating cifCl1it. .

Turning on Main On/Off Control
With the main ani aff control CD in the off position (' 0'), and the central heating
control CD in the ' .t: position, turn on the electricity supply. Turn main on/off
control CD into the' I' position, the mains on in~icator will illuminate.
Note: The main on/off control should only be operated If· os described under 'Check water contents' on page
7 . the boiler is correctly filled with water.
At this stage the TURBOmax is ready to supply hot water.

Obtaining hot water
'On opening a hot water tap @ at a supply point (basin, shower, bath, etc.) the boiler
will operate automatically to provide hot water. (A short delay may be experienced in
obtaining hot water at the tap, depending on the length of pipework and your system
layout. This delay can be reduced by not fully opening the tap until the water is flowing
at the desired temperature).
With. the tap fully open you will receive the maximum flow rate of hot water. Should
you require hotter waterreduce the' flow by partially closing the tap.
On dosing the tap the boiler automatically switches off (or continues to operate for
central heating if required). The pump may continue to operate for a short 14
period. .

Setting Maximum Domestic Hot Water Control
The maximum domestic hot water temperature can be adjusted using the hot water
temperature control CD.· .
Turn the cantrol:
Clockwise to Increase (maximum setting = 9)
Anti-clockwise to Decrease (minimum setting = 1)
As a guide, for normal circumstances the maximum hot water temperature should be
set to 6
Note: This control adjusts the maximum domestic hot water temperature. If adjusting the control upwards
appears to hove no effect on the temperature, then the boiler is olr~ody operating at full output for the selected
flow rate. If hotter water is required, the flow rote should be reduced by partially dosing the hot water top.

The maximum radiator temperature control CD maintains the temperature of water to
the central heating circuit at the desired level. This temperature is indicated on the .
pressure and temperature gauge ® during heating operation.
Turn the control:
Clockwise to Increase (maximum setting = 9)
Anti-Clockwise to Decrease (minimum setting = 1)

Setting external controls
Set the room thermostat <ID and/or thermostaticrodiator valves @ according to the
instructions supplied with the control (s). Set the external time control to the desired on
and off periods.
•
Note: A room thermostotor 0 room thermostat and therm astatic radiator valves will provide mare accurate and
economic control compared ta a heating system without these controls.
If your TURBOmax i~ fitted with a built in time clock, set this acco~ding to the
instructions supplied with the clock.

Switching on Central Heating Control
Turn the central heating control CD to 'mu: l\ I position. The boiler will now operate
automatically ta provide central heating for the conditions selected on the external
controls. (On this setting the TURBOmax will also provide domestic hot water).
The temperature gauge ® indicates the temperature of water to the central heating
circuit. After the boiler stops operating the pump may continue to operate for a short
period to fully disperse the heat from the boiler. . .
Note: The boiler incorporates an integral 'anti·cycling' economiser control to prevent energy wasteful on and
off operation of the boiler for short periods when in the central healing mo'de. When turning the room
thermostat or boiler thermostat to a higher setting there' may therefare be a short delay before the bailer
operates. .
In the summer time, when central heating is not required, turn the central heating
control CD into the' l\ I position:
Note: If a hot woter top is opened during central heating aperation, the boiler will momentarily switch off
before automatically igniting ta pravide hot water. .

When a hot water tap is opened or the central heating system requires heat, the boiler
automatically ignites and starts to operate. If no automatic ignition occurs within a set
period of about 9 seconds the boiler will reattempt ignition after a further delay of
approximately 10 seconds, if the boiler still does not start the lock out indicator will
illuminate (see Indicotor Lights) . A further ignition attempt can only take place once
the central heating control CD has been turned briefly to the reset position ~ and·
relea·sed. If after attempting to light the boiler by turning to the reset position, the
boiler shuts ·,down again or if an indicator light is flashing, consult your service agent or
Vaillant Service Solutions. .
·Note: Particularly when starting up for the first time, or after the boiler has been out of operation for 0 fairly
long period, it may be necessary to turn ,the central h~oting control to the reset position several times before .
ignition takes place.

If the boiler is not operated for several hours during very cold weather
there is the possibility of the system freezing. Please ensure that if you
ore absent during a period of frost the central heating system remains in
operation and all rooms are kept above freezing point. (It must be
remembered, however, that the boiler will be automaticolly 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 ga~ system. To
overcome this possibility you can drain" both the central heating" system"
and the boiler).
Note: The boiler has an internal frost protection thermostat, and in very
cold weather may therefore operate automatically to prevent damage to its-
elf. Thisfunction is only available when the main on/off control in the on
position (I) . "
Care and maintenance
Clean the outer casing with a damp cloth and a little soap. Do not use any
obrasives or solvent cleaning material which could damage the.case or plastic
fittings.
It is importan"t that the boiler is serviced at least once a year by a competent
service company. To ensure regular servicing it is strongly recommended that
" arrangements are made with your service' agent or Vaillant Ltd. for a
Maintainence Agreement. Please return the registration card if you would
like further details.
