CommISSIoNING AND mAINTENANCE

commissioning the system
- Slowly fill the tank and drain it by opening a hot water tap. Drain
all the taps and check that there are no leaks in the domestic
hot water system.
- Fill the whole system up to a minimum pressure of 1 bar
(preferably 1.5 bar), using the boiler's fill valve. Fill the system
slowly and drain it using the central heating flow pipe manual
air vent. Check that there are no leaks in the central heating
system.
Prestige excellence: purge the primary circuit of the tank by
means of the manual air vent on the top of the tank.
- Purge the circulator(s)
- Open the gas valve, drain the pipe and check that there are no
leaks in the system.
- Check that the siphon is filled.
- Connect the plug to the wall socket and power on the appliance.
If needed, place the room thermostat to its highest position.
The boiler should start. Check the gas pressure and allow
the boiler to heat up for a few minutes. Set the boiler to
High Power mode and check the CO
. Then, set the boiler to Low Power

mode and check the CO2 level again
.
Characteristics)
- Set the central heating and hot water temperatures following
the values given in the Directions for Use.
- Drain the central heating system again and, if necessary, re-fill it.
- Make sure the central heating system is correctly balanced
and, if necessary, adjust the valves to prevent a greater or
lesser flow than planned to some circuits or radiators.
CHECkInG THE SETTInGS
- Check that the parameters are set in accordance with the
user's needs: see page 3, Directions for Use.
- Check the boiler settings: this task can only be carried out by an
ACV-trained installer or by the ACV maintenance department.
- Set the appliance to High Power mode by simultaneously
pressing the mode and Plus keys.
- Check the dynamic gas pressure at the gas valve
. This must be at least 18 mbars.
below, ref. 1)
Wait a few minutes for the appliance to heat up to a minimum
temperature of 60°C. Check the CO
instrument. Please see in the Technical Characteristics for
optimum value. To increase the CO
counterclockwise; turn it clockwise to reduce the value
diagram below ref. 2).
Then put the appliance to High Power mode by simultaneously
pressing the mode and Plus keys. Wait a few minutes to stabilise.
Check the CO value. It should be either equal to the full power
2
value or a maximum of 0.5% less than this value. If you record
a significant deviation,please contact the ACV maintenance
department.

inspection and maintenance
ACV recommends that you have your boilers inspected
and cleaned if need be at least once a year.
Plug out the appliance before undertaking any work, even if only
recording measurements and adjusting the settings.
- Check that the siphon is not fouled, fill it, if need be, and check
that there are no leaks.
- Check that the safety valves are operating correctly.
- Drain the whole system and if necessary re-fill the appliance to
pressure of 1.5 bar.
If you have to refill your circuit more than twice a year,
please contact your installer.
- Check the boiler charge in High Power mode. If there is a
big difference between this value and the original setting, the
deviation could mean a blockage in the air intake pipes or flue
gas extraction pipes, or that the exchanger has become fouled
with an accumulation of dirt.
