When installing the device, it is advisable to place
the "out" and "backflow" on opposite sides, as can
be seen in the figure above.
In order to prevent damage to the stove by the boi-
ler overheating due to a faulty pump or lack of
electric power, we recommend that at least the
first three heaters in the system should be installed
so that they can work based on a thermo-siphon
system, using pipes with a greater diameter in
these sections.
We recommend the use of a thermal relief valve.
The outlet pipe of the said valve must be large, it
must be installed in a visible place and protected to
avoid spills or splashes.
It is absolutely obligatory to avoid all kinds of sip-
hons on pipes that lead to the expansion vessel.
When installing a DERO fireplace with a closed
expansion vessel, a number of safety require-
ments should be taken into account.
VERY IMPORTANT!
WE RECOMMEND THAT INSTALLATION WORK
ALWAYS BE CARRIED OUT BY A PROFESSIONAL
HEATING SYSTEM EXPERT.
If the stove should be lit by accident when there is
no water in the system, immediately put out the
fire so as not to damage the boiler. In such a case
NEVER FILL THE SYSTEM WITH WATER WHEN THE
FIRE HAS BEEN LIT IN THE STOVE.
The appearance of water on the inside walls of the
boiler, especially after lighting up for the first few
times, may be due to condensation. This will tend
to disappear with use.
The DERO SE fireplace has been designed for in-
termittent combustion.
