Safety instructions

Assembly
The combustion air fed to the unit must be free of
chemicals which contain, e.g. fluorine, chlorine or
sulphur. Sprays, solvents or cleaning agents, paints and
adhesives can contain such materials which can, in
certain circumstances, lead to corrosion when operating
the unit, including the exhaust gas installation.
In business premises such as hairdressing salons,
painting or carpentry workshops, cleaning businesses
etc., also when operating in room-air independent mode,
a separate room must always be used for the installation
which will ensure that the supply of combustion air is
technically free from chemicals.
It is not necessary to keep a clearance between the
appliance and combustible materials or components, as
at the rated heating power of the appliance, the
temperature here is always lower than the permitted
temperature of 85 °C.
Clearances in accordance with Section 4.3 must be
maintained for maintenance purposes.
Note concerning flue design:
The double stage system of the boiler with combustion
air matching produces high values of combustion
technological effectivity. This requires technical evidence
of the suitability of the flue in according with the
relevant standards.
Installation
Before the installation of the boiler, the comments of the
gas supply company and the district chimney sweep
must be obtained.
The boiler may only be installed by a suitably qualified
heating engineer. who also assumes the responsibility
for installing the appliance properly and putting it into
service for the first time.
Flush the heating system thoroughly before connecting the
appliance! By doing that, residue such as welds, cinder,
hemp, putty, rust, rough dust and similar substances are
removed from the pipes. Otherwise such substances can be
deposited in the appliance and cause damage.
Make sure that the connection and gas pipes are not
under stress when installed to avoid leakage in the
heating installation or in the gas connection!
To tighten or loosen bolts, only use suitable open-ended
spanners (do not use pliers or extensions etc.). Improper
use or unsuitable tools can cause damage, such as gas
or water leaks.
On closed heating installations, a type-approved safety
valve corresponding to the heat capacity must be fitted.
The gas regulating block may be tested for leakage only
with a maximum pressure of 50 mbar! Higher testing
pressures can damage the gas fitting.

Safety instructions and regulations 3
The electrical installation may only be performed by a
heating engineer.
There is a danger to life by electrocution from current-
carrying components! The supply terminals in the
terminal box of the device are under voltage even if the
mains switch is off. Before working on the appliance,
turn off the power supply and secure against restart.
Important instructions for propane appliances
Bleeding the liquid gas tank when installing the system:
before installing the device, make sure that the gas tank
has been bled. The liquid gas supplier is responsible for
the proper bleeding of the tank. Ignition problems can
be caused if the tank is not bled properly. In such cases,
first contact the person in charge of filling the tank.
Affix tank sticker:
Affix the enclosed tank sticker (propane quality) on the
tank where it is clearly visible, if possible close to the
filler nozzle.
Start-up
Do not add frost or corrosion preventative to the
heating water! If frost or corrosion preventative is added
to the heating water this can cause changes in the seals
and can cause noises to be created during the heating
process. Vaillant assumes no liability for this and such
consequential damages. Please inform the user of the
procedure for frost protection. If the heating water
hardness is above 3,6 mol/m
softened. To do this you can use the ion-exchanger,
Vaillant spare part number 990 349. Please observe the
enclosed operating instructions.
For natural gas:
If the connected pressure is outside the range 17 to
25 mbar, the unit must not be operated!
For liquid gas: (37 mbar)
If the connected pressure is outside the range 35 to
45 mbar, the unit must not be operated!
Inspection and maintenance
Inspection, maintenance and repair work should only be
undertaken by an approved heating installation company.
Inspections / Maintenance work not carried out can result
in damage to property and personal injury.
Risk of fatal electric shock from touching live
connections! The supply terminals in the terminal box of
the device are under voltage even if the mains switch is
off. Before working on the appliance, turn off the power
supply and secure against restart.
Protect the switch box from water splashes.
Danger of explosion through gas leakage! The mixer tube
between the gas control unit and burner must not be
opened. It can only be guaranteed that this component is
gas-proof after it has been checked at the factory.
