1.3 Warnings
General warnings
Incorrect installation, adjustment, alteration, maintenance activity or repair may lead to material
or environmental damage and/or injuries. The appliance should therefore be installed, adapted
or converted by a skilled and qualified installer, taking into account national and international
regulations. Faulty installation, adjustment, alteration, maintenance activity or repair shall render
the warranty void.
Appliance
When installing wall air heaters, you must comply with the national and, if applicable, regional and
local regulations (e.g. gas company regulations, building regulations etc.). The wall air heater may
be installed only in an area and position suitable for the purpose, see Chapter 2 Installation.
Gas supply and connection
Before installation, check that the local distribution conditions, gas type and pressure and the
current adjustment of the appliance all match. An approved gas stop cock must be fitted to the
inner pipeline.
Flue gas discharge and outlet for flue duct/exhaust pipe
Combustion air supply piping and flue gas discharge piping should include as few bends as possible;
in general, resistance should be kept to a minimum, and the same diameter should be maintained
along the entire length under all circumstances. The exhaust pipe may not be supported on the
heater; instead, it should be appropriately suspended! If the exhaust pipe is laid alongside or
through flammable walls or flooring, a sufficient gap must be left between this and the pipe to
prevent fire.
