If 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.

Danger to life from poisoning by flue gas

There is a danger to life from escaping flue gas.

▶Never modify any parts through which flue gas is

routed.

Explanation of symbols and safety instructions

Condens 5000 W – 6720644144 (2019/03)

If flues are damaged or leaking, or if you smell flue gas,

observe the following rules.

▶ Switch off the heat source.

▶ Open doors and windows

▶ Warn your neighbours and leave the building

immediately.

▶ Prevent third parties from entering the building.

▶ Notify an approved contractor.

▶ Have any defects rectified.

Danger to life from carbon monoxide

Carbon monoxide (CO) is a poisonous gas, which

arises during the incomplete combustion of fossil

fuels such as oil, gas or solid fuels.

Dangers arise, if carbon monoxide escapes from the

heating system due to a fault or a leak and collects

unnoticed in enclosed spaces.

You can neither see, taste nor smell carbon monoxide.

To avoid danger from carbon monoxide:

▶ Have the heating system inspected and serviced

regularly by an approved contractor.

▶ Use a CO detector, which gives an alarm in good

time if CO escapes.

▶ If you suspect a CO leak:

Explanation of symbols and safety instructions

– Warn your neighbours and leave the building

immediately.

– Call an approved contractor.

– Have any defects rectified.

Inspection and maintenance

If there is a lack of cleaning, inspection or

maintenance, or if these are carried out incorrectly,

this may result in material damage and/or personal

injury, including possible loss of life.

▶ Have work carried out only by an approved

contractor.

▶ Have any defects rectified immediately.

▶ Have the heating system inspected once a year by

an approved contractor, and have any required

maintenance or cleaning work carried out.

▶ Have the heat source cleaned at least every two

years.

▶ We recommend that you enter into a contract

covering an annual inspection and needs-based

maintenance with an approved contractor.

Conversion and repairs

Improper modifications to the heat source or other

parts of the heating system can result in personal

injury and/or material damage.

▶ Have work carried out only by an approved

contractor.

▶ Never remove the casing of the heat source.

▶ Never carry out any modifications to the heat

source or to other parts of the heating system.

▶ Never close the outlet of the pressure relief valves.

Heating systems with DHW cylinder: During heat-

up, water can escape from the pressure relief valve

of the DHW cylinder.

Open flue operation

The installation location must be adequately

ventilated, if the heat source draws its combustion air

from the room.

▶ Never cover or reduce the size of ventilation

openings in doors, windows and walls.

▶ Consult a contractor to ensure that ventilation

requirements are met:

– If structural modifications are made (e.g.

replacing windows and doors)

Condens 5000 W – 6720644144 (2019/03)

Explanation of symbols and safety instructions

– If devices with an air discharge to the outside are

subsequently installed (e.g. extractor fans,

kitchen fans or air conditioning units).

Combustion air/ambient air

The air in the installation location must be free of

flammable or chemically aggressive substances.

▶ Do not store or use any highly flammable or

explosive materials (paper, petrol, thinners, paints

etc.) within the vicinity of the heat source.

▶ Do not store or use any corrosive substances

(solvents, adhesives, chlorinated cleaning agents,

etc.) within the vicinity of the heat source.

Condensate tube

Condensate is produced in this wall mounted gas

condensing boiler and removed via a condensate

tube. Modification or blocking of the condensate tube

is not permitted.
