FEATURES

Operation
The Calorio M gas-fired convector is an independent
modulating heating appliance with sealed combustion
chamber and forced draught.
It has been designed to be installed inside the room to be
heated.
It is suitable for operation with natural gas (G20) and LPG
(G30/G31) (gas-fired convector belonging to category
II
2H3+
according to EN 1266).
The combustion air intake and the exhaust of flue gases
take place outside via two coaxial pipes and are ensured
by the operation of a blower placed in the combustion cir-
cuit. Therefore, the gas-fired convector must be installed
on an external perimetral wall or close to it, depending
on the maximum extension of the pipes (see Paragraph
The operation principle of the Calorio M gas-fired convec-
tor is based on a convective motion of room air that pass-
es through the gas-fired convector from bottom to top,
is heated and diffused into the room through the upper
grille. The recirculation of the room air is facilitated by the
presence of a modulating fan placed in the lower part of
the gas-fired convector.
For this reason, do not place clothes, newspa-
pers or any other object that could obstruct the
air outlet directly on the grille. Also make sure
that curtains, backs of chairs or furniture are
not placed at a distance of less than 30 cm from
the gas-fired convector.
The operation of the gas-fired convector is made very sim-
ple and fully automatic by the control board and control
panel with digital display, fitted as standard; in fact, the
only operations required of the user are to start the gas-
fired convector, select the required temperature and the
periods of operation.
In heating mode, the heat output and airflow rate
modulate according to the room temperature measured
by the temperature probe.
The sealed combustion chamber is the best guarantee of
safety for the environment in which the gas-fired convec-
tor is installed: there is no possibility of the products of
combustion leak, nor is the oxygen necessary for combus-
tion taken from the environment. The appliance, once in-
stalled in accordance with the installation standards, does
not require any ventilation openings in the room.
A flame detection device using an ionisation probe in-
terrupts the gas supply in the event of an accidental
shutdown.
The presence of the fan also allows summer operation:
only the fan will work causing a pleasant air flow within
the room.
