9.5 EXTERNAL HORIZONTAL
CONVENTIONAL FLUE (GREEN
SYSTEM)
This option uses the Grant Green system External Module straight
starter section (GKM90C), replacing the low level terminal and
ue guard supplied with the boiler, along with components from
the Grant Green system. See Figure 9-4.
It is possible to extend the ue horizontally by a maximum of 3
metres in total ue length by using the green system. A maximum
of two 45° elbows may be utilised when extending the ue using
this system.
For further information on the connection of the Green system,
please refer to Section 9.4.
! NOTE !
The ue system from the external module can be extended
either vertically OR horizontally by using the Green
System.
NOT a combination of both.
A complete list of Grant Green system ue components can be
found in Figure 9-3 and Table 9-1.
Information on the siting of the ue terminal can be found in
Section 9.6.
