CommISSIoNING AND mAINTENANCE
commIssIonIng the system
- If a hot water tank is installed, fill the tank slowly and purge it by
opening a hot water outlet. Purge all the outlets and make sure
there are no leaks in the domestic hot water system.
- Fill the whole installation to at least 1.5 bar using the
system’s filling kit . Fill the system slowly and bleed it using
the manual air vent of the flow pipe. Check for leaks in the
central heating system.
- Purge the circulator(s).
- Open the gas valve, purge the pipe and check for leaks in the
system.
- Check that the condensate trap is full.
- Switch on the appliance at the isolator. Where appropriate, put
the room thermostat at its highest setting. The boiler starts
up. 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
2
.
(see table of technical characteristics)
. Next, set the boiler to
minimum power mode and check the CO
2
(see table of technical
characteristics)
.
- Set the central heating and hot water temperatures according
to the values indicated in the instructions for use.
- Bleed the central heating system again, and, if needed, fill to
reach the desired pressure.
- Make sure that the heating system is properly
balanced, and, if needed, adjust the valves to prevent certain
circuits or radiators from getting a flow rate that is far above or
below the set rate.
CHECkINg THE SETTINgS
- Check if the parameters are set to meet the user’s
requirements.
- Checking the boiler’s settings: only an ACV-trained installer or
the ACV maintenance department can perform this task.
- Set the appliance to maximum power mode by pressing
simultaneously the
mode
and “
+
” keys.
- Check the dynamic gas pressure at the gas valve (see diagram
below, ref.1). This must be at least 18 mbar.
Let the appliance heat for a few minutes until it reaches at
least 60 °C. Check the CO
2
setting of the appliance using a
measuring instrument. The optimal value is indicated in the
table of technical characteristics. To increase the CO
2
value,
turn the venturi screw counter-clockwise , and turn it clockwise
to decrease this value (see diagram below, ref. 2).
Next, set the appliance to minimum power mode by
pressing simultaneously on the
mode
and “
-
” keys.
Let the appliance stabilize for a few minutes. Check the CO
2
value. It should be either equal to the value at full power or a
maximum of 0.5 % less than it. If you observe a significant
deviation, please contact ACV’s maintenance department.
Special rule in Belgium:
for the Prestige Solo 50 - 75
The CO
2
, gas flow, air flow and air/gas supply
parameters are factory preset and cannot be changed
in Belgium.
X 3
The OffSET setting (3) of the gas valve is set at
the factory and sealed. It cannot be modified!!!
Adjust the CO2 setting by turning the throttle’s
adjusting screw (2).
Depending on the position of the throttle in the
valve, turn the adjusting screw either clockwise or
counter-clockwise to increase the CO2.
The offset (3) is factory-adjusted and must not be
modified on-site.
