INSTALLATION
DOMESTIC HOT WATER CONNECTION
PRESTIGE AQUASPEED / EXCELLENCE
The Prestige Aquaspeed and Prestige Excellence boilers can
be connected directly on the domestic hot water circuit.
Flush out the system before connecting the domestic hot
water part.
The installation must be fitted with an approved safety unit
with a 6-bar safety valve, a non-return valve and a shut-off
valve.
During the heating process, the domestic hot water dilates
and the pressure increases. As soon as the pressure exceeds
the safety valve setting, the valve opens and discharges a
small quantity of water. Using a hot water expansion vessel
(2 litres at least) will prevent this phenomenon and reduce
water hammer effect.
Prestige AquaSpeed
If the flow demands become too high, the desired water
temperature will not be reached. To avoid this phenomenon,
we recommend that you place a flow limiter in the cold
water pipe just before the appliance.
Prestige Excellence
Drain the tank by opening a hot water tap.
Caution: the presence of air in the circuit usually causes
noisy air discharge effects.
The hot water output temperature may reach
temperatures in excess of 60°C, which can cause
burns. We therefore recommend that that you install
a thermostatic mixer immediately after installing the
appliance.
If stop valves are used in the domestic hot water
system, they can cause pressure waves when
closed. Use devices designed to reduce water
hammer to avoid this phenomenon.

CONNECTION TO THE GAS
- The Prestige is fitted with a 3/4” male fitting connector,
on which you can connect the gas tap.
- You must comply with the applicable regulations (e.g. NBN
D51-003) for gas connections, and the other standards
in force in the country of installation.
- Where there is a risk of dirt stemming from the network,
place a gas filter upstream from the connection.
- Drain the gas pipe and check in minute detail that all the
boiler pipes, both inside and outside, are sealed.
- Check the gas pressure in the system. Consult the technical
characteristics.
- Check the gas pressure and consumption when commissioning
the appliance.
