11.2 Handing over the boiler to the operator
a
Danger!
Risk of poisoning and burns caused by
escaping hot flue gas!
Hot flue gas can escape and cause poisoning
and burns if the boiler is operated with
an incompletely mounted or open air/flue
gas duct or if the boiler is operated with
internal leaks with the front casing open.
> Operate the boiler
- for commissioning
- for testing purposes
- in continuous operation
only when the front casing is fitted and
closed and the air/flue gas duct is completely
fitted.
> Exclusively for test purposes such as gas
working pressure testing the boiler may
be operated with the front casing
removed for short durations ONLY but
must have a completely mounted air/flue
gas duct.
> After completing the installation, stick the 835593
sticker in the user's language to the front of the boiler.
The sticker is delivered with the boiler.
You must brief the operator of the boiler on the handling
and function of the ecoTEC pro.
> Explain the importance of regular maintenance by a
competent skilled trade company to the operator.
It is strongly recommended that a maintenance contract
be taken out to ensure regular maintenance. Important
information is available from Vaillant Service Solutions
(0870 6060 777).
> Complete the benchmark Benchmark gas boiler commissioning
checklist which is found at the end of these
instructions.
If this boiler is not installed and commissioned in accordance
with the manufacturer's instructions, this may void
the guarantee (Note: Your legal rights remain unaffected
by this.)
> Handover the boiler to the operator.
> Explain the basic operation of the heating installation to
the operator.
> Provide the operator with all relevant instructions and
boiler documentation.
> Go through the operating instructions with the operator
> Reply to his questions if necessary.
> Make the operator aware of the need to keep the instructions
in a handy location near the boiler, but not in or on
the boiler.
> Draw special attention to the safety instructions, which
the operator must follow.
> Instruct the operator that no changes or adaptations
must be made to the flue system or combustion air supply.
These must both terminate outside of the building
and be constructed only from approved components.
> Explain to the operator how he should monitor the water
level/filling pressure of the system.
> Explain to the operator which measures are required to
top up and purge the heating installation if required.
> Explain to the operator how to correctly set the temperatures,
the controllers and the thermostatic radiator
valves (economically).
> Complete and sign off the Benchmark commissioning
check list.
> Complete and sign off the guarantee documentation.
