INSTALLATION
CONNECTION TO THE GAS
- The HeatMaster
®
TC is fitted with a Ø 3/4” male fitting
connector, on which you can connect the gas tap.
- The gas connection must comply with the applicable
regulations (e.g. NBN D51-003 in Belgium) 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.
DOMESTIC HOT WATER CONNECTION
Before pressurising the central heating circuit
(primary) you should first pressurise the domestic
hot water tank (secondary).
The HeatMaster
®
TC boiler 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 7-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.
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 the rmostatic 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.
