1 General points
ISOTWIN CONDENS F 35 E boiler
is an appliance that uses condensing
technology, which recovers heat present
in waste gas.
Thanks to this operating principle,
the boiler consumes less energy and
decreases NOx and CO2 emissions.
ISOTWIN CONDENS F 35 E boiler has a
double use (heating + instantaneous hot
water).
This appliance of the room-sealed type
is equipped with a flue exhaust and air
intake for combustion products called the
flue system. This flue system connection
principle offers the possibility to install the
appliance in any room and with no specific
ventilation requirements.
The installation and the commissioning
of the appliance has to be carried out by
a skilled professional who is responsible
for the compliance of the installation and
the commissioning according to current
regulations.
You also have to call on a skilled
professional for the maintenance and the
repairing of the appliance as well as for
any gas adjustment.
Saunier Duval has specially designed
different accessories for your appliance
depending on your installation.
