Flue Outlet - FULTON J Series Installation, Operation And Maintenance Manual

2.4

FLUE OUTLET

The boiler is supplied with a stainless steel flue spigot that should be inserted into the flue outlet in
the back of the boiler and secured with the three angle clips supplied loose in the trim box.
The height and type of flue will generally be subject to local planning regulations and approvals.
The following information is intended to provide assistance where the installation of a simple flue is
required.
Where multi-boiler flues or difficulties are experienced, specialist advice should be obtained. The
flue diameter must be the same or larger than the flue flange provided with the boiler and the outlet
should be at least 1 meter higher than the nearest ridge to avoid down draughts.
Where a chimney cowl is fitted, care should be taken to ensure that the distance between the
lowest point of the cowl and the top of the flue is 1.5 x the diameter of the flue, and that it is of the
terminal cone type.
Note:
a) If the flue layout is such that it may produce an excessive up-draught, a draught stabiliser may be required.
b) Avoid fitting 90° elbows whenever possible, if unavoidable compensate by increasing the flue diameter.
c) Ensure all flue pipes from the boiler to the main flue have a rising pitch.
