General information on the heating system
a
Caution!
Malfunctions!
Flush the heating system thoroughly before
connecting the appliance! In this way, residue
such as cinders, hemp, putty, rust, welding res-
idues, coarse dirt and similar substances are
removed from the pipes. Otherwise such sub-
stances can be deposited in the appliance and
cause damage.
• A safety valve must be fitted to the boiler as de-
scribed in BS 6644.
• The system shall be vented at high points to prevent
air locks.
• The system shall be filled and drained in accordance
with guidance in BS 6644 and the current Water Reg-
ulations.
The safety temperature limiter fitted to the boiler
serves, in addition to the water pressure switch, as a
low water level safety device.
The fault-induced shut-down temperature of the boiler
is approx. 110 °C (nominal shut-down temperature 110 °C,
tolerance -6 K).
• If plastic pipes are used in the heating installation, you
must fit a suitable thermostat to the heating flow line
on site. This is required to protect the heating installa-
tion from temperature-related damage. The thermo-
stat can be wired to the plug for the contact thermo-
stat (blue ProE plug).
• When using non diffusion resistant plastic pipes in the
heating system, you must install a plate to plate heat
exchanger downstream for system separation, to pre-
vent corrosion in the boiler.
