1 GENERAL RULES
This Manual is an integral and essential part of this device and must be carefully stored in its vicinity for purposes of rapid consultation.
Read the instructions and warnings provided herein
carefully because they provide important information
regarding safety, installation, use and maintenance.
Installation must be performed exclusively by qualified
professional personnel in complete respect of the safety
regulations in force. The Manufacturer declines all liability for damages caused by the erroneous installation or
incorrect and/or inappropriate use of the device.
Keep all potentially dangerous packaging elements
(nylon, polystyrene foam, wood, staples, etc.) far from
the reach of children.
The device must be started for the first time by qualified
personnel only.
Immediately switch off the device whenever it stops
and/or malfunctions. All repairs must be performed by
qualified personnel using original spare parts only.
Failure to observe the above can compromise operational safety.
Scrupulously respect the indications provided by the
Manufacture to guarantee satisfactory operation.
Never leave clothes, paper or other objects that might
obstruct the passage of hot air from the slots on top of
the radiator.
Delicate surfaces such as curtains, furniture, and wooden or plastic chairs must be kept at a minimum distance of 30 cm from the device.
Provide extra protection against the risk of burning by
contact of children, the elderly or disabled with the hot
surfaces of the shell wherever necessary. Such additional protection must not obstruct the passage of hot air
and the irradiation of heat from the front panel.
2 GENERAL TECHNICAL CHARACTERISTICS
2.1 Device classification

2.3 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) 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 combustion 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 device functions automatically, and is equipped with
the appropriate systems for safety, control, mixing, combustion, starting, the suction of combustion air and flue
gas expulsion.
The combustion air suction and flue 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.
2.4 Principal elements of the control and safety systems
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 flame 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 off 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 flame convector models - a multifunctional valve with single control and combined
manual all-or-nothing thermostat control equipped
with thermoelectric flame detection device with
reset inhibition, maximum flowrate pre-selection
device or pressure regulator, minimum flowrate preselection screw, all-or-nothing modulation thermostat, pilot flame output with gas flowrate pre-selection screw, inlet filter and pilot filter, 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 flame by keeping the dial pressed down for a few seconds. Then
release the dial and check to make sure that the
pilot flame remains on. If the pilot flame has gone
out in the meantime, the reset inhibition device will
prevent the re-starting of the convector until the
established pilot flame detection device safety time
has elapsed.

ATTENTION: the KING gas convector must be installed at 10 cm minimum distance from the ground; it
is necessary to forsee the space for the gas interception. The hole for the gas pipe has to be provided
under the appliance, between the appliance and the ground, according to the gas inlet of the appliance
itself.
