HIf you smell gas
A gas leak could potentially cause an explosion. If you smell gas, observe
the following rules.
▶ Prevent flames or sparks:
– Do not smoke, do not use a lighter or strike matches.
– Do not operate any electrical switches or unplug any equipment.
– Do not use the telephone or ring doorbells.
▶ Turn off the gas supply at the main shut-off valve or at the gas meter.
▶ Open windows and doors.
▶ Warn your neighbours and leave the building.
▶ Prevent anyone from entering the building.
▶ Move well away from the building: call the emergency services and
the gas supplier.
HDanger to life from explosion
An increased and permanent ammonia concentration may lead to stress
corrosion cracking on brass (e.g.gas valves, union nuts). As a result,
there is a risk of explosion from gas escaping.
▶ Do not use wall mounted gas boilers in rooms where there is an
increased or permanent ammoniac concentration (e.g. livestock
stables or storage room for fertilisers).
HDanger to life from poisoning by flue gas
There is a danger to life from escaping flue gas.
▶ Ensure that flues and gaskets are not damaged.
HDanger of death from poisoning by flue gas due to inadequate
combustion
Danger of death due to flue gas leak. If flues are damaged or leaking, or if
you smell flue gas, observe the following rules.
▶ Close the fuel infeed.
▶ Open doors and windows.
▶ If necessary, warn all residents and leave the building.
▶ Prevent third parties from entering the building.
▶ Rectify any damage to the flue gas pipe immediately.
▶ Check the combustion air supply.
▶ Do not cover or reduce the size of ventilation openings in doors,
windows and walls.
▶ Ensure that there is adequate combustion air supply, including for
any appliances installed at a later date, e.g. extractor fans, kitchen
fans or air conditioning units that discharge air to the outside.
▶ Never operate the device if there is insufficient combustion air
supply.
HInstallation, commissioning and maintenance
Installation, commissioning and maintenance may be performed only by
an approved contractor.
▶ In the case of open flue operation: ensure that the installation
location meets the ventilation requirements.
▶ Do not repair, manipulate or deactivate safety-relevant components.
▶ Only install original spare parts.
▶ Check for gas tightness after working on gas-carrying components.
HElectrical work
Electrical work must only be carried out by electrical installation
contractors.
Before starting electrical work:
▶ Isolate all poles of the mains voltage and secure against
reconnection.
▶ Make sure the mains voltage is disconnected.
▶ Before touching live parts: Wait at least 5 minutes to discharge the
capacitors.
▶ Observe the wiring diagrams of other system components as well.
