Connecting water piping (see
DANGER: RISK OF BURNING/SCALDING
In case of high leaving water setpoints for space heating (either a high fixed setpoint
or a high weather-dependent setpoint at low ambient temperatures), the heat
exchanger of the boiler can be heated up to temperatures higher than 70°C.
In case of a tapping demand, it is possible that a small volume of water tapping
(<0.3 l) has a temperature higher than 70°C. To prevent scalding, it is recommended
to install a thermostatic valve according to the following schematic:
d
a=boiler, b=domestic hot water from the boiler, c=cold water inlet, d=shower,
e=thermostatic valve (field supply)
WARNING
Ethylene glycol is toxic. If you add glycol to the water, do NOT install freeze
protection valves. The valves release the toxic glycol when they are activated.
Possible consequence:
▪
Heart, kidney or liver damage in case of glycol swallowing or skin contact with
glycol.
▪
Nausea, sickness and diarrhea in case of glycol inhalation.
WARNING
Ethylene glycol is toxic.
