Model Number: L1PB45-YC Brand Name: DUOLE Key Specifications/Special Features: Adopt German IC, Digital technology control the running of system;The user can set up the temp. Of heating and domestic water within limits at his own choice. It can auto-regulate the gas consumption.The combustion chamber adopt imported ceramic plate for thermal insulation, high thermal efficiency, and gas-saving.Enclosed design of air supply and smoke exhaust; the other components is in complete insulation during the burning so that it can prolong the service life of parts and electronic components.The water routes are integrated design; nice technology process; improve the reliability of the system at the same time.

Closed design of water routes; reduce the corrosion of the heating system; the mounting position is not limited indoor.

In the winter, the function of heating and domestic water supply can automatic shift according to the users’ needs.

Internal electronic clock, set local time precisely (with timing function);

The user can set the running condition of the gas boiler at any time according to the needs.

Gas proportional regulation: adopt the gas proportional valve; the control system can make proportional regulation, and get very stable temperature of heating water and domestic water, so it is comfortable to use the gas boiler.

The water pressure protection: it will be decompression by the safety valve. The boiler will show fault code when the water pressure is too low.
