H If you smell gas
Close gas isolator.
Open windows and doors
Never operate electrical switches, including
telephones, plugs or doorbells.
Extinguish any naked flames.
Never smoke.
Never use any lighters or sources of ignition
of any kind.
Warn all occupants in the building, but do not ring
doorbells.
If you can actually hear gas escaping, leave the
building immediately.
Prevent third parties from entering and notify the
police and fire brigade as well as the gas supplier
and heating contractor from outside the building.
H Danger of explosion of flammable gases
Any work on components that carry gas may only be
carried out by an approved contractor.
H Danger posed by explosive and easily
flammable materials
Never use or store easily flammable materials
(paper, curtains, clothing, thinners, paints, etc.)
near the device.
Observe all local regulations in relation to the
storage of combustible materials at the installation
location.
H Danger through short circuits
To prevent short circuits:
Only use original cabling by the manufacturer.
H Danger through electric shock when the boiler
is open
Before opening up the boiler, isolate it completely
from the mains power supply and ensure the power
cannot be inadvertently reconnected.
It is not enough to switch off the control unit.
H Danger if you smell flue gas
Switch off the boiler.
Open windows and doors.
Notify an approved contractor.
H In devices with open-flue mode:
there is a risk of poisoning from flue gas if there
is an inadequate combustion air supply
Ensure that there is an adequate combustion air
supply.
Do not cover or reduce the size of ventilation
apertures in doors, windows and walls.
Ensure that there is an adequate combustion air
supply, including for any devices 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 an insufficient
combustion air supply.
H Danger of escaping flue gases
Ensure that the flue pipes and gaskets are not
damaged.
Ensure that the boiler is not equipped with a
thermostatic flue gas damper downstream of the
flue gas connection.
Use of motor-controlled supply air flaps is permitted.
H Installation and operation
Correct and proper installation and adjustment of
the burner and the controller are the fundamental
requirements for safe and economical operation of
the boiler.
The boiler must only be installed and adjusted by an
approved contractor.
Do not change parts at the boiler as otherwise the
approval would be invalidated.
Never modify any parts through which flue gas is
routed.
Electrical work must only be carried out by qualified
electricians.
With open flue operation: do not cover or reduce
the size of ventilation apertures in doors, windows
and walls. Make sure that windows that are used as
combustion air vents cannot be shut accidentally.
Attach a warning sign near the window. If draft-
proof windows are installed, ensure an adequate
supply of combustion air.
If the supply air flaps can be closed via motors,
combustion must only start when the supply air flap
is fully open (volt free checkback signal to the boiler
controller via failsafe limit switch). Provide for
control of supply air flaps.
Make sure the boiler installation location is frost-
proof.
