Maintenance operations must be carried out by an authorised company (e.g. Authorised Aer-Sales Technical Assistance Cen-
tre).
Trouble Possible causes Solutions
Smell of gas
Caused by leakage from gas circuit pipe-
lines.
Check sealing eciency of gas intake circuit.
Repeated ignition blocks No gas. Condensate drain clogged.
Check the presence of pressure in the network and that the gas adduction
valve is open. Restore the function of the condensate drain, checking that
the condensate has not aected: combustion components, fan and gas
valve. Check the function of the condensate sensor.
Irregular combustion or
noisiness
Dirty burner, clogged primary heat ex-
changer, incorrect combustion parame-
ters, intake-exhaust terminal not correctly
installed.
Check the indicated components.
Siphon blocked
Dirt or combustion products deposited in-
side.
Check that there are no residues of material blocking the ow of
condensate.
Heat exchanger blocked.
is may be caused by the drain trap being
blocked.
Check that there are no residues of material blocking the ow of
condensate.
Abnormal noises in the
system
Air in the system.
Check opening of the special air vent valve cap (Par.1.36). Make sure the
system pressure and expansion tank factory-set pressure values are
within the set limits. e factory-set pressure values of the expansion
vessel must be 1.0 bar, the value of system pressure must be between 1 and
1.2 bar.
Abnormal noises in the
condensation module
Air in the module.
Use the manual air vent valve (Parag. 1.36) to remove any air inside the
condensation module. When the operation has been performed, close
the manual air vent valve.
Poor production of DHW
(when the storage tank
unit is combined)
Condensation module or clogged DHW
heat exchanger.
Contact Aer-Sales Assistance Service that has procedures to clean the
module or D.H.W. heat exchanger.
