Installation of Vertical Discharge Wall Terminal
With Rear Outlet
In order to determine the length of concentric tube required to correctly terminate a rear outlet
extended vertical discharge arrangement, the following procedure should be followed.
1. Measure wall thickness W in mm - see fig 16.
2. Mark off and cut flue tubes following guidance shown in fig 17 below.
Flue tubes should be cut to length TL in mm. Both inner and outer tubes should be cut flush with each
other, square and any burrs removed.
Where TL required is greater than 610 mm, (*850mm) then additional lengths (as appropriate) of
80/125 Concentric tube will be required to extend the vertical discharge wall terminal.
