10.1 Technical information
Control box: Satronic TFI 812 B mod. 10.
Main supply: 240V - 50 Hz.
Minimum ionisation current: 5
µ
A.
Reaction time flame protection: 1 sec.
Safety time: < 10 sec.
Maximum ambient temperature: 60
°
C.
Injector size pilot burner: Ø 0.8 mm.
Injector size main burner: Ø 4.4 mm.
Burner pressure full load: 11.8 mbar (100%).
Burner pressure part load: (High/Low version only):
4.2 mbar (60%).
Warning:
Control box operates on a neutral/phase supply.
10.2 Commissioning the boiler
1. Check gas connections.
2. Check electrical supply (L/N and earth).
3. Check water connections and if the installation is filled.
4. Switch on circulation pump and check rotation direc-
tion.
5. Open main gas cock (release air in gas pipe work).
6. Switch on electrical supply.
7. Set the control thermostats at about 85
°
C.
8. After a waiting time of about 12 seconds you will get
ignition. At a minimum ionisation current of 5
µ
Amp
the ignition stops. 15 sec. later the safety gas valve
will open, the boiler is on.
9. Leave the boiler on for a couple of minutes to get rid
of air in the gas pipe.
10. Set the correct burner pressure.
11. Check the thermostats for correct operation.
12. Check the flame protection, start the boiler with
disconnected ionisation probe.
10.3 Switching off the boiler
1. Switch off the electrical supply.
2. Turn off the gas cock.
10. COMMISSIONING
11.1 General
It is essential for a good combustion, to clean the boiler,
the gas train and boiler room once a year.
11.2 Maintening the boiler
1. Clean the internal flue ways of the boiler with a steel
cleaning brush (available from Broag).
Remove top casing and top of the flue hood.
2. Clean the burners internally and externally.
3. Clean boiler room and the floor underneath the boiler.
4. Clean the boiler casings.
5. Clean the gas train, ignition, pilot burner, thermostats
and wiring.
6. Check start program, ignition time and safety times.
7. Check flame protection, and thermostats.
8. Check the boiler input at 100% and 60% load
(High/Low version only).
9. Make a combustion efficiency calculation.
10. Check the boiler and installation for water leakage.
11. Check gas train and gas pipe for gas leakage.
