Wall-hung indoor gas boilers<br />
•“bithermal compact” XILO<br />
- Open (mod. MC) and proof chamber (mod. MCS) boilers suitable for<br />
hot sanitary water heating and supply.<br />
- Suitable for low temperature system operation.<br />
- Reduced overall dimensions (-20% if compared to the standard<br />
boilers).<br />
- High-efficiency bi-thermal copper exchanger.<br />
- Atmospheric burner, in stainless steel for all kinds of gas.<br />
- Ionization flame control electronic ignition.<br />
- Electronically controlled proportional modulation for heating and<br />
sanitary circuit.<br />
- Proof combustion circuit with flue discharge electrical fan (mod. MCS).<br />
- Safety FLUE CONTROL preventing burnt gases from entering the<br />
room (mod. MC).<br />
- Slow opening gas valve.<br />
- Combustion chamber provided with ceramic fibre insulation.<br />
- High-prevalence circulator.<br />
- 8 Lt. expansion tank.<br />
- Instruments for unit control and regulation.<br />
- Flue standard intake in the boiler (mod. MCS).<br />
- Precedence flow meter.<br />
- IP X4D protection degree.<br />
• Installation and Maintenance<br />
- Easy installation thanks to template connections and water connection<br />
kits (on demand).<br />
- Maintenance is made simple thanks to easy accessibility to internal<br />
components.<br />
