Check-list for commissioning a heater:
Step
Action
Check
1 - Before switching on.
Check the electrical connections.
(general power, connection of accessories,
thermostat...)
2 - Before pressurising
Check the expansion tank
pre-inflation pressure.
The tank may loose pressure, particularly if it has been
stored for a long time.
3 - Switch the appliance on, with no
demand.
Deactivate heating and hot water
using the control panel buttons.
Un-stick the pump
Screw giving access
to the motor shaft for
unblocking
4 - Place the heating circuit under
pressure.
Open the taps on the fixing jig.
Check that all heating circuit taps
are open.
Raise the pressure to 2 bar.
Water leaks.
Automatic bleeding must be triggered (P07).
The appliance will be unavailable for five minutes.
Attention:
if pressurisation lasts less than 15 seconds (for example by opening the valves of the connection plate when the
installation is already pressurised), the automatic bleeding sequence cannot take place. It is therefore recommended to run this
sequence manually using the function P.07 (see § “test mode” in “Technical specification” chapter), before running bleeding of the
installation (next stage).
5 - Vent the air from the heating
circuit. Reset the pressure after
bleeding.
Start test function P.06 (see § test
mode in “Technical specification”
chapter).
Open the heating and installation air bleed valves.
6 - Vent the domestic hot water
circuit.
Open the hot water taps to remove
the air.
7 - Turn on the gas.
Open the gas tap on the fixing jig.
Carefully check for leaks with an electronic detector or
soapy water.
8 - Boiler configuration at
installation.
Adjust the various parameters on
the installation menu depending
on the installation and the acces-
sories. Set the heating flow rate
through the bypass if necessary.
Check the value displayed on the After-Sales menu
item d44 (ionisation quality). If this value drifts over
time, it indicates a deterioration in flame detection.
9 - Run the appliance in heating
mode
Check that the water circulates correctly and that the
appliance shuts off correctly when reaching the tempe
-
rature set.
Check the exhaust circuit for leaks.
Check that the heating flow rate is adequate.
10 - Run the appliance in domestic
hot water mode
Check the hot water temperature. Ensure that it meets
the user’s requirements.
11 - Explain the appliance to the
end-user.
Explain the main operations : ON/
OFF, RESET, filling the system,
DHW and heating temperature
adjustment,
Take care that the end-user has his
booklet.
