6.7 FINAL CHECKS & USER HANDOVER
Check the individual burners maximum rate and combustion are to specification. Operate the boiler at
maximum loading and check gas consumption against the guidance table below to ensure the rating
is correct.

When commissioning is satisfactorily completed the user must be instructed on the use and opera-
tion of the boiler and in particular detail:
- Hand over to the user the “Programming guide” as well as all other literature
relating to the appliance.
- Explain the importance of air vents and the flue outlet system, and that they should
not be altered or interfered with in any way.
- Explain to the user the importance of internal water pressure and how to restore it
to the correct value if required.
- Explain and demonstrate to the user the correct function and adjustment of the
temperature, thermostats and radiators for the economic use of the system.
- Remind the user that in order to comply to the regulations in force the boiler has to
be inspected and serviced regularly as indicated by the manufacturer.
-
Explain the frost protection systems for this appliance:
If the internal water temperature of the appliance falls below 8
o
C the system
pumps will operate to circulate water around the system. If the internal
water temperature drop below 5
o
C, a burner will be activated to bring the
internal water temperature up 16
o
C.
NB. Other Frost protection levels can be set according to the options fitted
and the requirements of the customer. See Operating and Programming guide
for more details
-
Explain that an anti-legionella programme is available for the DHW system, but is
defaulted to be off, but can be activated if required.
- Explain that at 10:00 every Friday the boiler will cycle every pump controlled by
it, for approximately 30 seconds each. This is a feature designed to reduce the
instances of pump seizure, when the system is not in use (
subject to the boiler
being in control of the pumps rather than an external BMS)
.
Finally, these instructions should be handed over to the user for safe keeping.
