According to the manufacturer, the series is intended for heating family homes and residential buildings. The model is therefore particularly interesting for operators who want to use a classic pellet heating system with automatic fuel supply and controlled boiler operation.\u003c\/p\u003e\n\u003cp\u003eThe unit is particularly useful where a pellet-fired heat generator with buffer tank integration is to be integrated into an existing or newly built heating system.

Emission values for CO, NOx, OGC, and dust are specified in the technical documents. According to the data sheet, these values were determined with approved pellets in accordance with EN ISO 17225-2.\u003c\/p\u003e\n\u003ch3\u003eCompatibility \u0026amp; System Integration\u003c\/h3\u003e\n\u003cp\u003eThe device is intended for water-based integration into a heating system. The manual explicitly describes use with a buffer tank; according to the documents, two buffer sensors are included in the scope of delivery of the control system. The manufacturer recommends installing a buffer tank, even though the boiler can generally also be operated without a buffer.\u003c\/p\u003e\n\u003cp\u003eAdditionally, a room thermostat can be integrated. For the flue gas connection, a chimney with at least 120 mm inner diameter and at least 5 m height is described; the flue pipe should not be longer than 3 m. In emergency wood log operation, a double thermal drain safety device or an open heating system is required according to the manual.\u003c\/p\u003e\n\u003ch3\u003eTechnical
