This document is applicable to slow heat release appliances for solid fuel (freestanding manually fuelled intermittent burning slow heat release appliances (SHRA) having heat storage capacity such that they can provide heat and release it for an extended period after the fire has gone out). The intended use of the appliances is space heating in residential buildings. They can be fitted with a boiler or heat exchanger (integral part of the appliance containing water to be heated up) for the supply of hot water for central heating systems. These slow heat release appliances may be supplied either as an assembled appliance or as a pre-designed unit consisting of prefabricated components designed to be built on site in accordance with the-specified assembly instructions. These appliances can burn one or more types of the following solid fuels as specified: — wood logs; — compressed untreated wood; — wood pellets; — lignite briquettes; — solid mineral fuels; — peat briquettes. This document is not applicable to: — mechanically fed appliances — appliances with fan assisted combustion air — one off installations This document specifies procedures for assessment and verification of constancy of performance (AVCP) of characteristics of solid fuel burning slow heat release appliances.
