You should only install and maintain the appliance if you are a certified and competent installer in the field of
gas-fired heating;

Do not make any changes to the appliance;

If you are installing an appliance that must be built in;

use non combustible and heat-resistant material for the chimney breast, including the top of the chimney
breast, the material inside the chimney breast and the back wall against which the appliance will be placed.
For this you can use both sheet material and stone-like materials;

take sufficient measures to prevent high temperatures of the wall behind the chimney breast, including the
materials and/or objects that are behind the wall;

comply with the minimum required internal measurements of the chimney breast;

vent the chimney breast by means of ventilation holes with a combined passage as stated further down in
the text;

use heat-resistant electric connections and make sure that they do not make contact with the appliance;

If you are installing an appliance with an open combustion: use a suitable flue gas discharge system that is
provided with the CE label;

if you are installing an appliance with a closed combustion: only use the concentric systems supplied by DRU;

if you are installing a free-standing appliance: place the appliance away from the back wall by the minimum
distance stated further down in the text;

do not cover the appliance and/or do not wrap it in an insulation blanket or any other material;

make sure that combustible objects and/or materials have a distance from the appliance of at least 500 mm

only use the accompanying wood/pebble set and place it exactly as described;

the space surrounding the pilot burner, 2nd thermocouple or ionisation pins must remain free;

make sure there is no dirt in gas pipes and connections;

place a gas tap in accordance with applicable regulations;

prior to putting into operation, check the complete installation for gastightness;

if your appliance is provided with explosion hatches on its top, you must make sure that they cannot be blocked

3.4 Second thermocouple safety

(if applicable, see Appendix 2, Table 2)

It is possible, that the appliance to be installed has 2 thermocouples. Thermocouple 1 is always next to the pilot
burner, thermocouple 2 is always elsewhere above the main burner.
If the appliance is provided with a second thermocouple safety on the main burner, you need to know that it will
intervene if no proper transfer has taken place from the pilot burner to the main burner or from the main burner
itself. The gas supply will be interrupted after 22 seconds. In order to solve a poor or non-existent transfer from
the pilot burner to the main burner, please use the malfunction search diagram in Appendix 1.
