8.1.1 Conventional Flue Guidelines
The flue system should be designed in accordance with local bye-laws and the
Building Regulations. Draught stabilisers are not recommended for oil fired
boilers. Sharp bends or horizontal runs should be avoided and the flue should
terminate 2 feet (600mm) above the ridge of the dwelling. Terminals which restrict
the discharge or allow ingress of water should be avoided.
When connecting to an existing masonry chimney, a Warmflow HFL or VFL
flexible flue liner suitable for use with oil fired condensing boilers and of an
appropriate diameter must be used. The annular space must be filled with
insulation and sealed top and bottom.
Only Warmflow‟s flue systems designed specifically for use with oil-fired
condensing boilers may be used.
