Flue system
8.5.1
Flue pipe and air supply
The boiler utilises a special concentric flue adapter which can only be used with the
elbow that is part of the horizontal or vertical flue pipes. For the appropriate types see
chapter 6 Accessories.
Note
Only use approved Intergas flue products with this boiler, which can be sourced from
the supplier of your boiler or Intergas stockist.
The standard horizontal flue pipe is not supplied with the boiler and should be
purchased separately from your supplier. This flue may be routed to the rear, left or
right of the appliance by means of the 90
0
degree bend, which is supplied in the flue
kit.

terminals
CAUTION
Once the flue has been installed and the appliance
commissioned, installer should observe the plume direction.
Particular attention should be drawn to plume vapour re-
entering the boiler via the air intake. If this occurs, it is highly
possible the flue is fitted within a negative pressure area and
therefore a plume management kit (PMK) must be fitted.
