Maximumallowable flue length varies betweenappliances and must be followed to ensuresafe and correct appliance operation asillustrated below. In calculating the fluelength the following must be considered:• Each duct extension measures 817mmwith a 767mm useable length(i.e. 50mm seal)•A 90° extension elbow has anequivalent length of 767mm - this isknown as the resistive length•A 45° extension elbow has a resistivelength of 375mmACE3000mm MAXIMUM FLUE LENGTH - requires 3 extensions•FINESTOuter Section - Telescopic Flue (supplied with boiler)•In extending the flue ducting it is alsopossible to raise or lower the horizontalducting.

T win-Pipe SystemsIn special applications where verylong runs of flue ducting are desired,it is possible to use a twin-pipesystem. The Best and Finestappliance ranges may use atwin-pipe system in either horizontalor vertical form but on certainoutput models only.The Ace and Finest Goldcombination boilers are not testedfor use with a twin-pipe system.Maximum flue lengths varybetween appliance types and mustbe followed to ensure safe andcorrect operation as illustratedbelow.
