INSTALLATION
DHW CONNECTION
The DHW tank must be pressurized before putting the
primary circuit (heating) under pressure.
The HeatMaster® boiler can be connected directly to the DHW circuit.
Flush the system before connecting the domestic hot water circuit.
The installation must be fitted with an approved safety group, comprised
of a 7 bar safety valve, a check valve and a shut-off valve.
During the heating process, the domestic hot water expands 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 liters at least) will prevent this
phenomenon and reduce the water hammer effect.
The hot water output may reach temperatures in excess of
60°C, which can cause burns.
ACV therefore recommends that you install a thermostatic
mixing valve immediately after the appliance outlet.
If stop valves are used in the domestic hot water system,
they can cause pressure changes when closed.
Use devices designed to reduce water hammer effect to
avoid this phenomenon.
