ATLAS D 30 SI UNIT
Checks during operation
• Ignite the appliance as described in sec. 2.3.
• Check that the fuel circuit and water systems are airtight.
• Check the efficiency of the flue and air-fume ducts while the boiler is working.
• Check that the water is circulating properly between the boiler and the systems.
• Check the proper ignition of the boiler by performing various tests, turning it on and
off with the room thermostat or remote control.
• Check that the burner door and fume chamber are tight.
• Check that the burner works properly.
• Analyse the combustion (with the boiler unit stable) and check that the content of
CO in the fumes is between 11% and 12%.

• Check the parameters are programmed correctly and perform any required custom-
ization (compensation curve, power, temperatures, etc.).
4.3 Maintenance
Periodical check
To ensure correct operation of the unit over time, have qualified personnel carry out a
yearly check, providing for the following:
• The control and safety devices must function correctly.
• The fume exhaust circuit must be perfectly efficient.
• Check there are no obstructions or dents in the fuel supply and return pipes.
• Clean the filter of the fuel suction line.
• Measure the correct fuel consumption
• Clean the combustion head in the fuel outlet zone, on the swirl disc.
• Leave the burner running at full rate for approximately ten minutes, then analyse
the combustion, checking:
- All the elements specified in this manual are set correctly
- Temperatures of the fumes at the flue
- CO2 percentage content
• The air-fume end piece and ducts must be free of obstructions and leaks
• The burner and exchanger must be clean and free of deposits. For possible clean-
ing do not use chemical products or wire brushes.
• The gas and water systems must be airtight.
• The water pressure in the cold water system must be approx. 1 bar; otherwise, bring
it to that value.
• The circulating pump must not be blocked.
• The expansion tank must be filled.
• Check the magnesium anode and replace it if necessary.
The boiler casing, control panel and aesthetic parts can be cleaned with a soft
A
and damp cloth, if necessary soaked in soapy water. Do not use any abrasive
detergents and solvents.
Boiler cleaning
1. Disconnect the power supply to the boiler.
2. Remove the front top and bottom panel.
3. Open the door by undoing the knobs.
4. Clean the inside of the boiler and the entire path of exhaust fumes, using a tube
brush or compressed air.
5. Then close the door, securing it with the knob.
To clean the burner, refer to the Manufacturer's instructions.
Burner disassembly
• Remove the cover (B) by undoing the screw (A), thereby making all the accessories
accessible.
• Undo the nut (C) and position the burner so as to access the nozzle.

4.4 Troubleshooting
Diagnostics
The boiler is equipped with an advanced self-diagnosis system. In case of a boiler fault,
the display will flash together with the fault symbol (detail 22 - fig. 1) indicating the fault
code.
There are faults that cause permanent shutdowns (marked with the letter "A"): to restore
operation press the RESET button (detail 8 - fig. 1) for 1 second or use the RESET on
the remote timer control (optional) if installed; if the boiler does not restart it is necessary
to eliminate the fault indicated in the operation LEDs.
Other faults cause temporary shutdowns (marked with the letter "F") which are automat-
ically reset as soon as the value returns within the boiler's normal working range.
