This document is applicable to residential solid fuel burning appliances of which the direct heat output is more than 6 % of the combined direct and indirect heat output at nominal heat output. This document specifies requirements relating to the design, manufacture, construction, safety and performance (efficiency and emission) of appliances fired by solid fuel (hereafter referred to as appliance(s) ) and provides instructions for them. Furthermore, it also gives provisions for the evaluation of conformity i.e. initial type testing (ITT) and factory production control (FPC) and marking of these appliances.
