Gas Connection
Important Indications
• Before installing the appliance and connecting it to gas supply, thoroughly check
the fixed elements of gas installation, which should meet the provisions of
construction law.
• Depending on type of gas, the intersection of gas supply line must be selected
according to regulations in force and properly installed.
• The connection may be established as fixed or detachable; if flexible tubes are
used, they must be made of stainless steel, pursuant to DIN 3383 Part 1 or
3384.
• Make sure that flexible tubes do not run on or near hot surfaces, are not subject
to stress or pressure and do not come into contact with sharp edges or other
objects that could damage the tube.
• If threaded connections are used with sealants or sealing materials, they must
be tested and approved by DVGW.
• Check if the gas cylinder (if it is included) is correctly set up and secured, and if
it is located in a dry place.
• Prior to installation of the appliance, make sure that it is set to gas and pressure
available in the installation location (see rating plate on the appliance and Table
1). If factory default settings are not suitable, the appliance must be adapted to
another type of gas (section 'Resetting to Other Type of Gas / Required
Settings').
• If the pressure in gas tube exceeds or drops below 10% of standard pressure,
install gas pressure controller, to provide for gas pressure stability.
• The attested gas shut-off valve must be installed in a easily accessible location
between the gas supply installation and the appliance, so that, if needed, gas
supply may be interrupted at any time.
• Gas connection stub is found at the back of the appliance.
