Luna Platinum

Luna Platinum range of wall-mounted boilers is composed of heating-only condensing boilers

with an output from 12 to 32 kW (at 80°/60°C). The range stands out for its high performance,

ease of use and installation and wide range of accessories for single installation or in cascade.

The core element of these condensing boilers is the heat exchanger in stainless steel AISI

316L. The low water content of the exchanger allows for very limited heat inertia and

therefore a rapid response to variations in heat demand on the system.

The steel surfaces protect the exchanger from the risk of corrosion caused by condensation.

The various parts of the generator are controlled by a latest generation electronics circuit board which makes for simple, reliable

boiler management using the extractable control panel with wide LCD display.

Daily and weekly programming of heating and DHW functions is possible, as is climatic setting according to the comfort criteria

chosen by the user and the visualisation of error messages relating to any faults. In addition, such boiler electronics allow

technicians to access a series of adjustment parameters and congure the generator so as to optimise efciency depending on

the type of system used.

Diagrams

As well as illustrating the heating system layout the gures below enable more detailed analysis of generator behaviour in

various conditions of use.

The pump ow rate-head curve denes the dynamic characteristics of the BAXI circulator inside the hydraulic group. As is known,

the temperature of the return water directly inuences the efciency of condensing boilers: at very low temperatures there is

better use of the latent heat and consequently improved boiler efciency. The graph below shows the variations in efciency, as

the ratio of the ow rate to the heat output of the condensing generator specied, depending on the return temperature of the

boiler. The last gure shows the trend of the ue temperature of the generator depending on the return temperature.

The boilers are predisposed for the connection of an external cylinder as provided at source with a motorised three-way valve.

The hydraulic connections of the boiler are shown in the gure below.

The DHW over-ride NTC sensor, supplied as an accessory, is connected to terminals 9-10 of the terminal board M2. The sensitive

element of the NTC sensor should be inserted in the dedicated well provided on the boiler itself. The temperature of the

domestic hot water and choice of DHW timer can be made directly from the boiler control panel.

Dual ue system installation

This type of pipe permits discharge of the combustion products both outside the building and in single ues. The air intake for

combustion may be placed in a different area from that of the discharge. The gaskets and screws of the previously removed from

the stopper should be used for air intake connector.

The 90° bend enables connection of the boiler to the ues and intake pipes in any direction thanks to the fact that they can

rotate by 360°. It can also be used as an additional bend in combination with the pipe or 45° bend. (A-B)

For special installations of the ues inlet/outlet ducts (B), the orienting dual ue system supplied as an accessory, can be used.

This accessory, in fact, can be used to move the inlet and out let in any direction thanks to the possibility of rotation at 360°.
