COMMISSIONING AND MAINTENANCE
− Check that the thermal unit has come to a complete stop
by setting the main switch of the equipment and the
main switch of the system to “off”.
If all the requirements are fulfilled, restart the thermal unit and
carry out the analysis of the combustion products by enabling
the test mode (Par. 200 = 1).
During the test mode (chimney sweeper), the equipment works
at the maximum power for a time period of 15 minutes, then it
is automatically disabled.
When using this function, it is recommended to leave one of the
domestic hot water valves open, in order to discharge excessive
heat.
Once the analysis of the combustion products is complete, dis-
able the function (Par. 200 = 0).

(*) The sampling hole for flue gas analysis must be made
on the straight section of the discharge duct, sufficiently far
from curves and elbows. For the hole size and its correct po-
sitioning on the discharge duct (minimum or maximum dis-
tance from the equipment outlet to be observed), refer to the
regulations in force.

Always plug the sampling hole after analysing the flue gas-
