Preparing for extended periods of disuse
The following operations shall be necessary if the thermal mod-
ule is not used for a long period of time:
− turn the main switch of the thermal modules and the
main system switch to "off"
− Close the fuel and water valves for the heating and do-
mestic hot water system.

Empty the thermal and sanitary system if there is a danger
of frost.
3.9
Maintenance
It is mandatory to perform maintenance and cleaning of the de-
vice at least once a year.
9
The non-performance of the annual maintenance will in-
validate the warranty.
This operation, carried out by Technical Assistance Service or by
professionally qualified personnel, is necessary to monitor and
ensure that the flue pipes inside and outside of the device, the
fan, the safety valves, the condensate removal devices, the wa-
ter drainage tubes and all the measurement and control devices
are in perfect working order.
Table of the compulsory maintenance activities (to be
performed every 2000 working hours or at least once a year)
Make the combustion test
Check the conditions of the inlet pipes (if present) and the
flue pipes by making sure that no leakage is present
Check the ignition electrode
Clean the combustion chamber and check the conditions of
the gaskets you have dismantled during such operation
Clean the condensate discharge pipe
Check the parameters settings
Check if there is any gas leakage
Check if there is any leakage on the hydraulic connections
Check the integrity of the cabling system and its related
connections
Make sure the ignition takes place regularly
Make sure that there is the flame after ignition
Check the safety devices down the equipment
Check the system pressure
9
Before carrying out any maintenance or cleaning, discon-
nect the power from the device by turning off the bipolar
main switch and closing the main gas valve. In addition,
for all maintenance (to be carried out at least once a year,
as noted above) always replace all the flue and gas seals, in
particular the burner seals.
Before performing any operation:
− disconnect the electric power supply by turning the main
system switch to "off"
− close the gas shut-off valve.
