5th class pellet boiler

The FLAT BASIC pellet boiler represents the latest compact boilers. Automation with Lambda probe and HT-Logic III autocontrol ensures easy operation. It is equipped with a burner with automatic cleaning, a system for mechanical, manual cleaning of the exchanger and a return protection pump.

The boiler structure is based on a vertical flame tube heat exchanger with a mechanical exchanger cleaning system. Burning is performed by a self-cleaning, automatic drop-in burner with an openable floor, equipped with an igniter, a photoelement and a thermocouple. The boiler is equipped with an exhaust fan which aerates the combustion process and improves the flue draught.

The boiler and the heating system are controlled by HT – tronic 900 weather-compensated controller which controls the operation of 4 pumps and a mixing valve actuator. The automatics can be expanded by connecting additional modules. The controller is compatible with a remote control panel, 2 room thermostats and an internet module. The controller is equipped with HT-Logic III autocontrol which controls the operation of the burner, selects the operating parameters and modulates power depending on the boiler temperature.

Operates in iPellR combustion optimisation standard with HT-tronic Lambda module. This system guarantees the highest combustion quality. The boiler is protected by a return protection pump with temperature sensor. It is suitable for fitting in a closed system in accordance with applicable legislation. The structure provides for smooth fitting, hydraulic connections can be routed upwards or to the rear of the boiler, flue gas can be routed upwards, backwards or to the right side of the boiler.
