gas connectIon
- HeatMaster® C boilers are equipped with a Ø 3/4”M connection
to connect a gas isolator.
- 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 of the connection.
- Purge the gas pipe and carefully check that there are no leaks on
the boiler’s internal and external pipes.
- Check the system’s gas pressure. Please refer to the technical data table.
- Check the gas pressure and consumption when commissioning
the appliance.
domestIc Hot water connectIon
The DHw tank (secondary) must be vented and pressurised
before filling and pressurising the heating circuit (primary).
The HeatMaster® C can be connected directly to the DHW circuit.
Flush the system before connecting the DHW circuit.
The system must be equipped with an approved safety unit including a 7 bar
safety valve, a non-return valve and a stop valve.
During the heating process, the domestic water expands and the pressure
increases. As soon as the pressure exceeds the safety valve setting, the valve
opens and discharges. The use of a DHW expansion tank (minimum 2 litres)
will avoid a discharge of water and reduce water hammer.
The hot water will reach temperatures greater than
60 °C, which can cause burns.
Therefore, the installation of a temperature control
valve on the hot flow immediately after the appliance
is advised.
If stop valves are used in the installation, they can cause
pressure waves when they are closed.
To avoid this, use devices to reduce water hammer.
