The SI 11A water heater has been designed and built to offer the convenience (with correct use) of hot water. The
unit consists of the following elements (see attached table).
1. Incorporated draught diverter:
Ensures correct combustion, even when the draught changes
in the flue.
2. Heat exchanger:
In pure electrolytic copper with thermal covering that ensures
maximum transmission of heat to the water.
3. Multigas burner:
high technology that fully exploits the gas consumed. Conversion
to another type of gas is possible by changing the nozzles and regulator pin.
5. Ignition safety valve:
Equipped with an electric system allowing the
gas to come out the burners only in safe conditions - presence of flame.
6. Power adjustment knob:
for manually setting the required power.
7. Temperature selector:
for setting the required hot water temperature.
9. Hydraulic device:
Automatically activates the water heating mechanisms
when a hot water tap is opened. It is also a SAFETY
SYSTEM, since it opens the gas flow to the burner only when water is circulating in the
exchanger.
14. Electronic ionisation probe:
For detecting the presence of flame
15. Burner ignition electrode
16. Temperature limiting thermostat.
17. Ignition microswitch.
18. Flue gas control device (T.T.B.)
Turns the water heater off in case
of insufficient draught or the presence of obstructions in the fume exhaust.
19. Battery box.
20. Hydraulic drain valve.
21. Electronic control module.
