Worked example of equivalent flue height
5.1.12 Where flue blocks are used, builders should ensure that no obstruction is created during erection. The installer should
ensure that the connection flue does not project beyond the internal wall of the flue blocks and that there is provision
for examination and servicing.
5.1.13
Important:
Before installing the appliance, carry out a visual check of the flue system as directed in the relevant
section of BS 5440 Pt. 1, then check the flue performance as follows:
a.
Close all doors and windows in the room in which the appliance is to be installed.
b.
Introduce some heat into the flue, using a blow torch or other means.
c.
Carry out a flow visualisation check with a smoke pellet at the intended position for the appliance. Ensure that
there is discharge of smoke from the correct terminal only, and no spillage into the room. Smoke coming out of
other than the correct terminal only, or a down draught or ‘no flow’ condition, indicates that the flue has failed
the test, and the appliance shall not be connected until the defect has been found and rectified, and the test
satisfactorily completed.
