Back Boiler Fireplace Prity ATC W20, 21.1 kW

Back Boiler Fireplace Prity ATC W20, 21.1 kW – corner panorama with cast iron door and radiator heating

The Prity ATC W20 Wood Burning Fireplace in an elegant black graphite finish is a corner model with panoramic glass and a cast iron door and windows – Prity's most refined corner fireplace with a back boiler. The 21.1 kW back boiler supplies the radiators in your home, while around 5 kW more heat radiates directly into the room where the fireplace is installed. This allows it to heat an area of up to 142 m² (around 384 m³). The wide combustion chamber (870 mm) creates an impressive, panoramic flame and takes logs up to 58 cm, while the internal ash pan makes cleaning easier. With energy class A, 80% efficiency and a 3-year warranty, this fireplace is a reliable solution for heating the whole home. Made in Bulgaria by Prity 95 Ltd – a manufacturer of heating appliances since 1995.

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.
• The body is large (1080 x 810 x 750 mm) and heavy (170 kg) – allow enough space in the corner and check the load-bearing capacity of the floor. Leave the panoramic glass uncovered when building the surround.
