KIT E CHIMNEY FLUE LINER KIT
(B23) - PART NO. 956082
2.6
This kit is suitable for open flue application in accordance with BS5440
where a room sealed flue installation is impractical. The kit comprises of
a flue adaptor from the appliance to the chimney, a flexible plastic flue
liner with connection parts and chimney terminal (see Figure 3f). Where
an open flue system is used, then an air vent must be provided in the
same room or internal space as the flue duct air inlet, see section 3.4.
For installation details refer to the flue kit instructions.
Maximum flue resistive length = 30m.
3f
A flue system can be built up from the components
detailed in the table, but the total flue resistance must
not exceed the maximum stated.
KIT F: TWIN FLUE SYSTEM (C53)
PART NO. 956080
2.7
This flue system kit is designed for installations where the air intake
position is different than the flue duct exit point. The kit comprises of a
twin adaptor from which the air intake is taken from the adjacent outside
wall (see example Figure 3g) and the flue duct is routed vertically
through the roof.
It has to be noted that the flue duct is under pressure when the appliance
is in operation and the duct can leak poisonous carbon monoxide if the
duct components are not correctly assembled. It is
not
recommended
to route the flue duct through living space areas, i.e. bed rooms, living
rooms etc.
For installation details refer to the instructions provided with the twin
flued kit.
For C53 flue systems the terminal for the supply of combustion air and
for the evacuation of combustion products shall not be installed on
opposite walls of the building.
Maximum flue resistance permitted for a twin flued system
= 52 Pa
Minimum flue resistance permitted for a twin flued system
= 23.5 Pa
