Warning
Control box operates on a neutral/phase supply.
10.2 Commissioning
1. Check gas connections.
2. Check electrical supply (L/N and earth).
3. Check water connections and if installation is fi lled.
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 thermostats at about 85°C.
The following will happen:
8. After a waiting time of about 13 seconds you will
get ignition. At a minimum ionisation current of 7
µA the ignition stops. The main gas valve will open.
The boiler runs.
9. Let the boiler run 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 the correct setting.
12. Check the fl ame protection, start the boiler with the
ionisation probe disconnected.
13. Check the water level control.
10.3 Switching off the boiler
1. Switch off the electric supply.
2. Shut off the gas cock.
Be aware of the possibility of the danger of frost.
Note:
Commissioning to only be carried out by a qualifi ed engi-
neer with the relevant training and certifi cation i.e. Acops
- Corgi and a commissioning data sheet completed on site
for issue to owner
11.1 General
It is essential for a good combustion, to clean the boiler,
the gas train and boiler room once a year. This prevents
dust from being aspired and fouling the burners and boi-
ler during operation, thereby avoiding poor combustion
and possibly build-up of soot deposits.
11.2 Maintenance
1. Clean the internal fl ue ways of the boiler. Remove
front casing and cleaning hatches, and remove the
burners.
2. Clean the burners internally and externally.
3. Clean the fl oor underneath the boiler and boiler
room.
4. Clean boiler casings.
5. Clean the gas train, ignition, pilot burner, ther
mostats and wiring.
6. Check start program, ignition time and safety times.
7. Check fl ame protection, and thermostats.
8. Check boiler input at 100% and 50% load.
9. Make a combustion effi ciency calculation.
10. Check the boiler and installation for water leakage
(seals).
11. Check gas train and gas pipe for gas leaks.
