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.

Draw 1 Package contents

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.

3 INSTRUCTIONS FOR INSTALLERS

3.1 Places of installation and safety distances

We recommend observing the following rules in order to obtain the maximum convector output efficiency:

- Position the device while bearing in mind the priority

areas to be heated, the absorption walls (windows, doors, French windows etc.), and the existence of shelves and other obstacles that might compromise the circulation of the hot air released by the radiator above and the effect of the heat radiated from the front panel.

- If more than one device must be installed in the

same room, we recommend staggered and opposing positioning in order to provide the entire area with uniform coverage.

- The devices must never be installed in recessed

niches or positions that do not ensure sufficient aeration for good operation.

- Install the devices along perimetral walls whenever

possible.

- Observe the following rules to simplify interven-

tions on the radiator or the removal of the shell:

a) the distance of the device from the floor must

never be less than 10 cm.;

b) any shelves installed above the radiator must be

positioned at least 10 cm higher;

c) a minimum distance of 10 cm from the wall must

be respected whenever devices are installed in recessed niches;

- avoid positioning furnishings above the shell.

Installation must be performed only by qualified professionals in complete respect of the safety regulations in force. The Manufacturer declines all liability for erroneous installation or the inappropriate or incorrect use of the device.

3.3 Gas line connection

The gas line connection must be made with respect to the regulations in force.

a) The device cannot withstand pressures of higher

than 40 mbar (0,04 bar) without risking the breakage of the gas valve membrane.

b) Always use ball valves and flexible joints for gas

when connecting the devices.

c) Gas supply line pressure adjustment: all the devices

are tested and calibrated at the Manufacturer’s factory for their respective operating pressures (see the data provided in the table).

To check the outlet pressure (Natural gas) use the check point 4 (Draw 30) and 1 (Draw 30a) placed above the valve outlet after removing the locking screw. In case the pressure value should not corrispond to the valued indicated check (burner working) the inlet pressure trough the check point (5 Draw 30) the inlet pressure must be

like indicated in the tables to the page 8, 9.

For gas LPG (butane-propane), the valve flow adjuster must be totally excluded. On the heaters supplied with EUROSIT valve turn anti-clock-wise 1/2 spin the pressure adjuster 9 (Draw 30). On the heaters supplied with WHITE ROGER or SIT 850 MICRO turn completely the pressure adjuster 3 as Draw 30a. To check the inlet pressure use the check point placed (5 Draw 30 and 2 Draw 30a) above the valve inlet gas connector. Whenever the inlet pressure values should not correspond to the value indicated on the regulation data table, adjust the pressure (burner working) manually trough the pressure adjuster placed on the top of the valve.

After these pressure adjustment operations have been completed, remember to close the pressure taps located on the gas safety valve using the respective screws.
