Diagram 3.3 - Shield configuration for combustible material protection
Diagram showing required dimensions for protecting combustible materials from uninsulated flue pipes. Shields must extend at least 1.5D beyond the flue pipe or create a path of at least 3D between pipe and combustible material, with minimum 12mm air space between non-combustible shield and combustible material.
shields should either:
a) extend beyond the flue pipe by at least 1.5 x D; or
b) make any path between flue pipes and combustible material at least 3 x D long
air space of at least 12 mm between non-combustible shield and combustible material
