1 Gas label
.
It is applied on the front part of the device and indicates the type of gas used by the modular system and the coun-
try of destination.
2 Technical data plate
It indicates the technical and performance data.
3 Serial number plate
This is located on the boiler body and specifies the serial number, model, and furnace power.

Spare parts and/or technical operation require the exact identification of the corresponding model. The absence of,
tampering with or removing the identification plates or other does not make it possible to reliably identify the product,
makes any installation and maintenance operation difficult and invalidates the warranty.
