1.3 General warnings
An 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 interna-
tional regulations. A faulty installation, adjustment, alteration, maintenance activity or repair shall
void the warranty.
Appliance
When installing radiant heaters, observe the national and, if applicable, regional and local regula-
tions (e.g. gas company regulations, building regulations etc.). Installation of a radiant heater is
only permitted in an area and a position suitable for the purpose, see Chapter 2 Positioning the
appliance.
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 and flexible connection
must be fitted to the inner pipeline.
Flue gas exhaust and outlet vent / exhaust duct
Combustion air supply pipelines and flue gas exhaust ducts should contain as few bends as possi-
ble. In general, the resistance should be kept to a minimum and in all cases the diameter should
be constant along its entire length. The duct may not rest on the radiant heater but should be
suspended efficiently! If the flue gas exhaust duct passes along or through combustible walls or
floors, the duct must be sufficiently free to prevent fire.
1.4 Think of your safety
If you smell gas, it is expressly prohibited
– To ignite an appliance
– To touch electrical switches, or to telephone from the area in question
Take the following actions
– Switch off the gas and electricity
