Do not smoke and avoid the use of electrical
appliances such as telephone, doorbell, light switch,
etc..
– Shut off main gas supply.
– Open windows and doors for ventilation.
– Warn all other occupants and evacuate the building.

How to proceed when waste gas is smelt
– Switch off the installation. Set main switch into „off“
position.
– Open windows and doors to allow ventilation.
– Contact your dealer.
Further warning indications
– Do not store or use explosive or (highly) inflammable
substances (such as petrol, paints, paper, etc.) in the
boiler room.
– Do not carry out any modifications on the heating unit,
fittings, or the actual construction.
– Aggressive chemical substances in the combustion air
may cause corrosion to the burner or the waste gas
system. This would result in reduced burner life. This
is why the boiler room should be free from solvents,
paints, glues, sprays, washing powder, etc.
