2.3 Basic safety information
>
Observe the following safety information at all times.
European installation directive
Installation and maintenance of the boiler must only be per-
formed by a competent person with valid accreditation from
the Health and Safety Executive in accordance with the
"Gas Safety (Installation and Use) Regulations 1998" (here-
inafter abbreviated to "competent person" or "heating spe-
cialist company"). The existing regulations, rules and guide-
lines must be observed when doing so. The competent per-
son is also responsible for inspection, maintenance and
repairs to the boiler, and alterations to the gas volume set-
ting.
IE only: The installation must comply with the current Ver-
sion of I.S.813 ‘Domestic Gas Installations’ and current
Building Regulations.
The current ETCI Regulations for installing electrical sys-
tems must also be observed.
Risk of poisoning and burns caused by escaping
hot flue gases!
Hot flue gas can escape and cause poisoning and burns if
the boiler is operated with an incompletely installed or flue
pipe or if the boiler is operated with internal leaks with the
front casing open.
>
Operate the boiler for start-up and in continuous mode
only when the front casing is fitted and closed and the
flue pipe is completely fitted.
>
For test purposes only (such as gas flow pressure test-
ing), the boiler may be operated with the front casing
removed for short durations ONLY but must have a com-
pletely installed flue pipe.
What to do in an emergency if you smell gas
Installation errors, damage, tampering, unauthorised instal-
lation sites or similar can cause gas to escape and result in
a risk of poisoning and explosion. If there is a smell of gas
in the building, proceed as follows:
>
Avoid rooms that smell of gas.
>
If possible, open doors and windows fully and ensure
adequate ventilation.
>
Do not use naked flames (e.g. lighters, matches).
>
Do not smoke.
>
Do not use any electrical switches, mains plugs, door-
bells, telephones or other communication systems in the
building.
>
Close the gas meter isolator device or the main isolator.
>
If possible, close the gas isolator cock in the gas supply.
>
Warn other occupants in the building by yelling or bang-
ing on doors or walls.
>
Leave the building.
>
If you can actually hear gas leaking, leave the building
immediately and ensure that others do not enter the
building.
>
Alert the fire brigade and police when you are outside
the building.
>
Notify the gas supply company or National Grid Transco
0800 111999 by telephone from outside the building!
What to do if you smell flue gas
Installation errors, damage, tampering with the unit, unau-
thorised installation sites or similar can cause flue gas to
escape and result in a risk of poisoning. If there is a smell of
flue gas in the building, proceed as follows:
>
If possible, open doors and windows fully and ensure
adequate ventilation.
>
Switch the boiler off.
>
Check the flue gas routes in the boiler and the flue gas
pipes.
>
In particular, check that the flue gas opening is not
blocked. If required, seek expert assistance for this.
Installation in rooms with ventilation
For open-flued operation, the unit must not be placed in
rooms from which the air is extracted using fans (for exam-
ple, ventilation systems, extractor hoods, tumble dryer ven-
tilation). These systems create negative pressure in the
room. As a result of the negative pressure, flue gas from
the opening is drawn through the annular gap between the
flue gas pipe and the shaft into the installation room.
The unit may only be operated dependent on the room air,
if simultaneous operation of the unit and fan is not possible.
>
To interlock the fan and unit, install the Vaillant acces-
sory multi-functional module 2 from 7.
>
Please inform the system operator of the possible risk
from running exhaust fans.
Material damage caused by corrosion
To prevent corrosion on the boiler and also in the flue pipe,
note the following:
>
Do not use sprays, solvents, chlorinated cleaning agents,
paint, adhesives or similar substances in the vicinity of
the boiler.
Under unfavourable circumstances, these substances may
cause corrosion.
Material damage due to improper use and/or
unsuitable tools
The use of unsuitable tools or improper use thereof may
cause damage, such as gas or water leaks.
>
To tighten or loosen threaded connections, only use a
suitable open-ended spanner (combination wrench) – do
not use pipe wrenches, extensions, etc.
Changes to the surroundings of the boiler
Changes may not be made to the following equipment:
– the boiler
– the gas, air and water pipes and power lines
– the flue pipe
– the drain line and expansion relief valve for the heating
water
– constructional conditions that could affect the opera-
tional safety of the boiler
