When installing a DERO fireplace with an open
expansion vessel, a number of safety requirements
should be taken into account.
When installing the radiators, do not place area
thermostat valves on all radiators. Part of the
installations (radiators) must always be open to
enable the heater to dissipate any overheating or
overspeed.
It is mandatory to include an expansion vessel
(open or closed) in the installation.
It is advisable to install a thermostat that will cut
the circulator whenever the water in the boiler is
below 50ºC. This will avoid condensation when
lighting the heater.
It is advisable for all installation components
(safety valve, circulator) to be installed on the
backflow.
Industrias Hergom S.A. declines all liability
connected with the installation. The installer must
comply with local regulations in order to install the
system correctly.
