The installer is responsible for proper installation and connection. Have a qualified specialist assess the chimney’s suitability and draft. The connection to the heating system and the overheating protection solution must be designed by a qualified specialist according to the specific model of the appliance. The stove must not be operated without water in the water jacket or without a properly connected heating system. The enclosed instructions apply to the cooling-air model; in a closed system, an external thermal drain and fill valve is required. Follow the instructions on the appliance’s nameplate and comply with local regulations.

Connecting the stove to a masonry chimney requires consultation with a specialist and may only be done at the consumer’s own risk.
