Boiler lockout
Should any malfunction occur, boiler automatically shuts down. Refer to no. 1 and no. charts for boiler status detection.
In order to detect the probable malfunction causes, see, in addition to no. chart, no. 8 “Troubleshooting” paragraph at the end of the
manual, as well.
Follow the described procedure with respect to the type of lockout.
2.5.1
Burner lockout
If the burner shuts down as there is no flame, the burner shutdown symbol is displayed and code E01
flashes.
Should this happen proceed as follows:
- check the gas stopcock to be open, and gas network is actually providing service, by lighting a gas powered kitchen appliance such
as a kitchen range or oven;
- once gas presence is verified, reset the burner by turning no.

knob (pic. 1) to the reset position
for two seconds, and then to the
desired mode position: should the boiler not start shut down, and after performing three reset procedures, contact the Fondital helpline
UK.
Should frequent burner lockout occur, a recurrent malfunction might be present: contact the Fondital helpline UK or qualified personnel
for service.
2.5.2 Shut-down due to overheating
When CH flow water overheats the boiler is shut down, the burner shutdown symbol is displayed and
code E0 flashes.
Should the above happen contact the Fondital helpline UK or CORGI registered engineer with appropriate
competence for service.
2.5.3 Shut-down due to inadequate air/flue gas draught
Should the boiler shut down due to air intake and/or flue gas discharge ducts malfunction, the burner
shutdown symbol is displayed and code E03 flashes (intervention of flue gas thermostats).
Should the above happen contact the Fondital helpline UK or CORGI registered engineer with appropriate
competence for service.
2.5.4 Shut-down due to incorrect fluid circulation
Should CH water circulation not be adequate, the boiler is shut-down.
The boiler shutdown symbol
is displayed and codes E10 or E6 flash, depending on the boiler function.
In the first case (flashing E10 code), the following situations may occur:
a)
the water pressure gauge (pic.4) indicates a pressure value lower than 1 bar
Follow the loading procedure as below described:
- open the loading tap upstream the boiler to fill the system with water;
- keep the loading tap open until the water pressure gauge reads 1÷1.3 bar;
- close the loading tap;
- reset the burner by turning no.
2
knob to the reset position
for seconds, and then to the desired mode position.
Should the boiler shut down again, contact the Fondital helpline UK or CORGI registered engineer with appropriate competence for
service.
Once the loading procedure is completed, properly close the loading tap. Should the tap not be appropriately closed, as
pressure increases, CH system safety valve may open and water flow out.
b) the water pressure gauge (pic.4) indicates a correct pressure value 1÷1.3 bar
Contact an authorized Service Centre or qualified personnel for service.
In the second case (flashing E6 code) contact an Authorised Service Centre or a qualified service engineer.
