SECTION 1 GENERAL INSTRUCTIONS AND TECHNICAL
CHARACTERISTICS
In this section there will be general instructions to be followed for the installation and use
of gas fired convectors Calorio series, a short paragraph about the operation of the gas
convectors, their main characteristics and the technical data.
1.1 GENERAL INSTRUCTIONS
This manual is an integral and essential part of this product and must be given to the end
user.
This unit must be exclusively used for the purpose it was intended. Any other use is to be
considered improper and therefore dangerous.
The manufacturer cannot be held responsible for any damage resulting from incorrect
installation or failure to comply with the manufacturer’s instructions.
The unit must be installed respecting the internal laws.
Do not obstruct the intake air of the fan neither the outlet air grid.
)
In case of failure and/or bad/poor operation, stop the unit (shut off the gas supply)
do not attempt any repair or direct servicing. Call only qualified service engineer.
Any misapplication of the above instructions can compromise the safety of the unit.
To ensure the efficiency of the unit and its proper operation, it is essential that a qualified
service engineer carry out annual maintenance in accordance with the manufacturer’s
instructions.
Qualified service engineers are those having specific technical experience in
the installation of heating units for residential applications, designated by a local authority.
Should the unit be sold or transferred to another owner, ensure that the manual remains
with the unit for the use of the new owner and/or the installer.
Before starting the unit, qualified personnel must check:
- that the electrical and the gas supply ratings do exactly correspond to those
shown on the original rating plate.
- that the exhaust flue and the inlet air supply are properly installed.
- that the combustion air feed and exhaust are properly fitted in accordance with
the existing standards.
- the proper internal and external sealing of the combustion apparatus
- that fuel flow control is in accordance with the unit power requirements.
- that the unit is fed with the specific type of fuel for which it has been pre-set.

- that the fuel supply pressure is within rated limits.
- that the fuel supply system is suitable for the unit and that all safety and control
devices required by the existing standards are duly installed
Do not use gas pipes to earth electric apparatus.
Avoid unnecessary supply when the unit is not in use and always close the gas valve.
In case of prolonged absence isolate the main gas inlet valve to the unit and disconnect
all electric supply.
IF YOU SMELL GAS
•do not activate electric switches, telephones or any other object or device that
may cause sparks.
•shut off gas supply.
•immediately open doors and windows to create drafts of air that purify the room.
•call for qualified servicing engineer.

1.2 PRODUCT DESCRIPTION AND MAIN OPERATING
CHARACTERISTICS
The Calorio gas heater, is an independent heating product with an isolated combustion
chamber and forced draught.
It has been projected to be installed indoor.
It can operate either with natural gas and liquid propane gas (category II2H3+, type C13,
regulation EN 1266).
The combustion air intake and the exhaust of fumes are external to the system through
two coaxial pipes and are drawn by the operation of an electric fan placed in the
combustion circuit. Therefore, the unit will have to be installed on an external perimeter
wall or close to it depending on the maximum extension of the coaxial pipe system (see
section Errore. L'origine riferimento non è stata trovata. ”Installation”).
The operation principle of the Calorio range is based on a convective movement of the
ambient air. The air going through the unit is drawn upwards and heated then diffused in
the ambient through the outlet grille. Particularly models 42, 51 and 52 are defined as
”ventilated” since the movement of ambient air is due to the presence of a fan placed in
the lower section of the unit. Except model 41, which is defined as ”static” since the
convective motion is natural.
The operation of the unit is very simple and completely automatic thanks to the
thermostatic regulation and the programmable timer (standard equipment on models 42
and 52, optional on the other models): The end user only needs to start the unit, choose
the desired temperature (to be selected on the thermostat) and, for the models 42 and 52,
set the operation period of the unit on the programmable timer.
The isolated combustion chamber is a best safety feature for the premises where the unit
is to be installed: there is no risk of leakage of the combustion products and neither
oxygen necessary for the combustion has been taken from indoor. It is not necessary
the installation of any grid or openings for the ventilation of the ambient.
A special flame detection device, that operates through a ionization flame sensor,
immediately stops the gas supply in case the flame accidentally goes off.
Models 42 and 52 grant a higher comfort thanks to an air humidifier placed on the left
hand side of the unit.
Additionally model 52 can also operate in summer time (the fan can work while the burner
is off). This allows a pleasant summer ventilation (movement of room air).
