The electrical installation must be carried in accordance with laws and regulation in force, as well as IEEE standards.
Electrical insulation of cables must be compliant with IEC 60227 or IEC 60245.
The warm air heater is delivered with all internal electrical connections already made with the exception of the general
power supply and the CAREL "Clima" regulator which must be performed by the installer following the instructions given
in the
ATTACHMENTS
Chapter of this manual. CAREL "Clima" regulator.
Never cut off the power supply to the warm air heater using general power switch, use the switch on
the heater electrical board.
Ø
Install the electrical switch near the warm air heater, with adequate power and voltage.
Ø
Connect the power switch to the terminal strip of warm air heater as described in the
chapter Electrical Diagrams
Ø
Connect the closing fire damper, if present, to the electric board.
Ø
The power supply cables must have an adequate section in regard of the absorption, and must be and have T
mark.
Ø
Grounding cable must be longer than the others of about 2cm.
Ø
The warm air heater must be connected with a grounding system in accordance with laws and regulations in
force.
It is necessary to provide, in order to allow the maintenance of the warm air heater, a complete insulation of the
heater itself from the general power line by installing, upstream of heater, an omnipolar switch according to current
regulations.
The switch must be of adequate section in regard of the overall electrical load of the warm air heater and burner.
The warm air heater must be powered with the following voltage(V)/phases/frequency(Hz):
Ø
230/1/50 for models 50 - 65 ;
Ø
400/3/50 for models from 80 to 600 .
When installing the CAREL "Clima" regulator, keep the following in mind:

differently from what is reported in the following paragraph it is possible
connect the warm air heater to a sized and built chimney
with certified materials and installed in compliance with national laws
and standards e local authorities as well as respecting the environment.
The pipes of the connecting duct from the warm air heater to the chimney
they must have a diameter greater than or equal to the smoke outlet on
the warm air heater and all joints must be sealed.
Check when sizing the connection ducts / chimney system that the maximum
pressure drop does not exceed 50 Pa.
