Before the equipment is used, for the  rst time the trap
must be  lled with water. To do this, add approximately
1/4 litre of water via the  ue outlet before  tting the  ue
system, or unscrew the cap on the trap positioned under-
neath the boiler,  ll it with water and re t it
Warning! Insu cient water in the trap can temporarily
cause the  ue gas to be expelled into the surrounding
ambient air
Under oor heating
For appliances with under oor heating, it is possible but not
necessary to  t a safety thermostat onto the under oor heating
outlet. For the electrical connection of the thermostat see the
section on “Electrical connections - page 25”.
If the outlet temperature is too high, the boiler will stop both
domestic hot water and the heating production and the error
code 1 16 “ oor thermostat contact open” will appear on the
display. The boiler will restart when the thermostat is closed
during automatic resetting.
If the thermostat cannot be installed, the under oor heating
equipment must be protected by a thermostatic valve, or by a by-
pass to prevent the  oor from reaching too high a temperature.
