Thank-you for purchasing the PAW unvented hot water cylinder.
The PAW is an unvented hot water cylinder in capacities 200 and 300 litres. Its energy efficiency as defined by standing
heat losses is the best in its class and will save the householder significant energy costs over the lifetime of the cylinder.
This manual gives detailed advice for installation and should be read carefully prior to fitting any unvented unit. PAW cylin-
ders are not suitable for gravity fed primary systems. In known hard water regions, precautions should be taken to prevent
limescale formation in hot water cylinders, in accordance with Building Regulation Part L, Domestic Heating Compliance
Guide.
This cylinder must be installed by a competent person and be installed in compliance with the Installation and Maintenance
Instructions, all current legislation, codes of practice and regulations governing the installation of unvented hot water cylin-
ders in force at the date of installation.
