Attention
First commissioning of a gas surface burner or the associated system must be carried out
by the manufacturer or a specialist appointed by the manufacturer following DIN 4794. This
person must be approved by the DVGW as a gas expert. There is a danger of fire if
flammable materials come into contact with the flame.

Attention
Every system must be equipped with an emergency switch.
Overheating damage of combustion chamber, casing, components etc. may occur when
the unit is operated with insufficient cooling (e.g. the unit is switched off via crash switch
and burner is still running) or the units are switched off via safety bodies.
There is a danger of fire if flammable materials come into contact with the combustion
chamber.
Check that there is a good distribution of the airflow at the inlet and outlet of the
combustion chamber!
