11.1.5 Sizing plastic flue systems (open flue)
When sizing the flue system, carry out a calculation of
the system based on the intended flue routing during the
engineering stage.
These examples are only for estimating the maximum
heights that can be achieved under the given conditions.
In the case of alternative conditions and to finalise the
sizing, calculate the flue system in accordance with
current technical rules and agree the result with the
local flue gas inspector [where appropriate].
