Recommendations
- The whole central heating system must be thoroughly flushed
with clean water before being connected to the appliance.
- Level the appliance using the provided support bracket.
- Noise may be amplified when the appliance is mounted on a
wall made of wood or other lightweight construction. Using
rubber dampers may reduce this effect.
- The heating connections are Ø 1”1/4 male [Prestige Solo 50
- 75] and Ø 1”1/2 male [Prestige Solo 120].
- Fit the heating system with a safety valve set to max. 3.0 bar,
connected to the drain, using a connection with an open section
(for inspection purposes), a suitable circulator according to the
pressure drops [boiler + system] and to the flow rate of the
system.
- The Prestige Solo 120 boiler is fitted with a safety valve set to
3.0 bar. Connect this to the drain, using a connection with an
open section (for inspection purposes) and a suitable circulator
according to the pressure drops [boiler + system] and to the
flow rate of the system.
- Fill the system with fresh tap water. Contact your
ACV representative about the use of inhibitors.
- The heating circuit must be designed so as to ensure a
continuous flow in the boiler; this flow may be obstructed if
all the thermostatic valves are closed. In this case, install a
bypass.
- Fit the condensate trap and connect the hose to the drain
using a connection that can be inspected. Fill the trap with
clean water. Make sure to prevent any risk of the condensates
freezing.

gas connectIon
- Our Prestige boilers are fitted with a gas connection [Ø 3/4”
male Prestige Solo 50 - 75] [Ø 1” male Prestige Solo 120] for
connection to a gas supply valve.
- The gas connections must comply with all applicable standards
(in Belgium: NBN D51-003).
- If there is a risk of dirt stemming from the gas network, place
a gas filter upstream from the connection.
- Purge the gas pipe and check in minute detail that all the
boiler’s internal and external pipes are sealed.
- Check the system’s gas pressure. Please refer to the table
with the technical data.
- Check the gas pressure and consumption when commissioning
the appliance.
settIng the poWer (prestige solo 120)
The power of the boiler may be adjusted from 80 to 120 kW for
natural gas and from 80 to 126 kW for propane gas.
Adjust the power by setting the speed parameters of the fan as
shown in the table below.
For the CO
