With energy class A, 78.3% efficiency and a 3-year warranty, the M W18 is Prity's most affordable 18.4 kW Back Boiler Fireplace.

Important for Installation and Operation

• Do not light the fireplace without water in the back boiler and without connected radiators or convectors – this will damage the appliance.
• An open heating system is recommended. With a closed system, a 1.5 bar safety valve is mandatory.
• The fireplace has no built-in overheating protection – the system must be designed and installed by a specialist.
• With forced circulation, it is advisable to power the circulation pump via a UPS so that it keeps working during a power cut.
• If the system contains copper components, protect it from electrolysis with a magnesium anode or similar protection. Protect all parts from freezing.
• The fireplace requires a chimney with a diameter of 200 mm. The connection to the system is via a G 1" inlet and outlet.
