CHARACTERISTICS
3.2 DEVICE CLASSIFICATION
For the classication we refer to the European standards EN 613: 2000 + A1: 2003 (balanced ow) and EN
1266: 2002 + A1: 2005 (forced ow).
Device type: C11 (King 21), C13 (King 30 FE e King 50 FE) and C12 (King 70 FE) depending on the ue gas
suction and expulsion system used. Device output class: 1
3.3 DESCRIPTION AND OPERATIONAL CHARACTERISTICS
The airtight gas convector radiator is composed of a combustion chamber for the combustion of a gaseous
component (methane or LPG) (entrust maintenance operations to a professional and qualied team in
compliance with the current national and local legislation in force in the country where the appliance
is installed, as reported in this manual), in airtight cast iron divided into two half-shells that can be opened
for cleaning and the inspection of the burner. The working temperature of the external surface of the combus-
tion chamber as fanned by the natural convection movement of the surrounding air or the forced circulation of
the fans is usually reached in a few minutes.
The functioning of the appliance is automatic. The device functions automatically, and is equipped with the
appropriate systems for safety, control, mixing, combustion, starting, the suction of combustion air and ue
gas expulsion.
The combustion air suction and ue gas expulsion systems must be mandatorily connected directly to the
building’s exterior (C-type devices) and therefore there is no contact between the combustion chamber and
the building’s interior. This guarantees the maximum safety and permits the installation of the device indoors
in complete respect of the standards in force.
3.4 MAIN CONTROL AND SAFETY COMPONENTS
a. Electric control unit for the Electronic series models: this can be of two types depending on the convector
model involved (forced or naturally balanced circulation). After receiving the electric signal from the room
thermostat, the control unit runs a normal check on the pressure-switch when forced convectors are being
controlled (if this check is not positive, the control unit does not grant triggering). The control unit then gives
the signal for the performance of the pre-starting lubrication of the combustion chamber (>4 lubrications) and
then the signal for spark ignition and starting by opening the gas solenoid valve. If no ame is detected (by
the ionization probe) within the established safety time, the device goes into lock-out. In order to reset after
lock-out, switch o󰀨 the bipolar switch with the orange l.e.d. and then switch it back on again.
b. Pilot gas valve: there is only one type of pilot gas valve for all pilot ame convector models - a multifunctional
valve with single control and combined manual all-or-nothing thermostat control equipped with thermoelec-
tric ame detection device with reset inhibition, maximum owrate pre-selection device or pressure regula-
tor, minimum owrate pre-selection screw, all-or-nothing modulation thermostat, pilot ame output with gas
owrate pre-selection screw, inlet lter and pilot lter, inlet and outlet pressure taps - lateral gas outlets or
gas outlets from below with RP 3/8 ISO 7 threads. To start, press the dial and switch on the pilot ame by
keeping the dial pressed down for a few seconds. Then release the dial and check to make sure that the pilot
ame remains on. If the pilot ame has gone out in the meantime, the reset inhibition device will prevent the
re-starting of the convector until the established pilot ame detection device safety time has elapsed.
c. Gas solenoid valve: for all electronic series and forced ventilation convectors, multifunctional and multigas
with a double safety solenoid valve (connected in series) in Class A and a built-in rectier bridge. The alumi-
num body holds the inlet gas connections - threaded G 1/2" outlet with respective pressure taps. Equipped
with pressure regulator to be adjusted only by qualied technicians, the only maintenance operation possible
on the valve.
d. Air suction unit: this serves to suck the air from the outside and inject it into the combustion chamber with the
consequent expulsion of the ue gases outwards through the appropriate ue gas duct.
e. Adjustment thermostat: this is a sensor-type thermostat that permits the temperature to be adjusted as
required by the user for a comfortable room temperature, and also permits the control of the starting and
switching o󰀨 of the device from the control unit.
f. Daily or weekly programmer (only on request): this serves to program the device’s daily and weekly opera-
tion cycles and is positioned on the control panel for access by the user for adjustment purposes.
