1 Safety
1.1 Action-related warnings
Classification of action-related warnings
The action-related warnings are classified in
accordance with the severity of the possible
danger using the following warning signs and
signal words:
Warning symbols and signal words
Danger!
Imminent danger to life or risk of
severe personal injury
Danger!
Risk of death from electric shock
Warning.
Risk of minor personal injury
Caution.
Risk of material or environmental
damage
1.2 Intended use
There is a risk of injury or death to the user or
others, or of damage to the product and other
property in the event of improper use or use
for which it is not intended.
The product is designed for use as a heat
generator for hot water generation.
Depending on the gas-fired boiler type, the
products referred to in these instructions
must only be installed and operated in con-
junction with the air/flue pipe accessories lis-
ted in the other applicable documents.
Intended use includes the following:
–observance of accompanying operating,
installation and servicing instructions for
the product and any other system compon-
ents
–installing and fitting the product in accord-
ance with the product and system approval
–compliance with all inspection and main-
tenance conditions listed in the instruc-
tions.
Intended use also covers installation in ac-
cordance with the IP class.
Any other use that is not specified in these
instructions, or use beyond that specified in
this document shall be considered improper
use. Any direct commercial or industrial use
is also deemed to be improper.
Caution.
Improper use of any kind is prohibited.
1.3 General safety information
1.3.1 Risk caused by inadequate
qualifications
–Set-up
–Disassembly
–Installation
–Start-up
–Maintenance
–Repair
–Decommissioning
▶Observe all instructions that are included
with the product.
▶Proceed in accordance with the current
state of technology.
▶Observe all applicable directives, stand-
ards, laws and other regulations.
1.3.2 Risk of death due to blocked or
leaking flue gas routes
Installation errors, damage, tampering, unau-
thorised installation sites or similar can cause
flue gas to escape and result in a risk of pois-
oning.
What to do if you smell flue gas in the prop-
erty:
▶Open all accessible doors and windows
fully to provide ventilation.
▶Switch off the product.
▶Check the flue gas routes in the product
and the flue gas diversions.
1.3.3 Risk of poisoning due to missing
flue gas monitoring device
Flue gases may escape into the installa-
tion room under unfavourable conditions. If
this happens, the flue gas monitoring device
switches the heat generator off. If a flue gas
monitoring device has not been installed, the
heat generator will continue to run.
▶Never decommission the flue gas monitor-
ing device.

1 Safety
4Installation and maintenance instructions atmoMAG 0020189893_03
1.3.4 Risk of poisoning caused by
insufficient supply of combustion
air
Conditions: Open-flued operation
▶Ensure that the air supply to the product's
installation room is permanently unobstruc-
ted and sufficient in accordance with the
relevant ventilation requirements.
1.3.5 Risk of corrosion damage due to
unsuitable combustion and room air
Sprays, solvents, chlorinated cleaning
agents, paint, adhesives, ammonia com-
pounds, dust or similar substances may lead
to corrosion on the product and in the flue
gas guiding.
▶Ensure that the supply of combustion air is
always free of fluorine, chlorine, sulphur,
dust, etc.
▶Ensure that no chemical substances are
stored at the installation site.
▶Ensure that the combustion air is not
routed through chimneys which have
previously been used with floor-standing
oil-fired boilers, or with other boilers,
which could cause soot to build up in the
chimney.
▶If you are installing the product in
hairdressing salons, painter's or joiner's
workshops, cleaning businesses or similar
locations, choose a separate installation
room in which the room air is technically
free of chemical substances.
1.3.6 Risk of death due to cabinet-type
casing
Cabinet-type casing can give rise to danger-
ous situations when used on a product which
is operated with an open flue.
▶Ensure that the product is supplied with
sufficient combustion air.
1.3.7 Risk of death due to explosive and
flammable materials
▶Do not use or store explosive or flammable
materials (e.g. petrol, paper, paint) in the
installation room of the product.
1.3.8 Risk of death from escaping gas
What to do if you smell gas in the building:
▶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, doorbells, telephones or other com-
munication systems in the building.
▶Close the emergency control valve or the
main isolator.
▶If possible, close the gas isolator cock on
the product.
▶Warn other occupants in the building by
yelling or banging on doors or walls.
▶Leave the building immediately and ensure
that others do not enter the building.
▶Alert the police and fire brigade as soon as
you are outside the building.
▶Use a telephone outside the building to
inform the emergency service department
of the gas supply company.
1.3.9 Risk of material damage caused by
frost
▶Do not install the product in rooms prone
to frost.
1.3.10 Risk of death due to lack of safety
devices
The schematic drawings included in this doc-
ument do not show all safety devices re-
quired for correct installation.
▶Install the necessary safety devices in the
system.
▶Observe the applicable national and inter-
national laws, standards and guidelines.
1.3.11 Risk of being burned or scalded by
hot components
▶Only carry out work on these components
once they have cooled down.
1.3.12 Risk of poisoning and burns caused
by escaping hot flue gases
▶Only operate the product if the flue gas
guiding has been completely installed.
