fl ue
=
18 meters
Permitted Flue Equivalent Length (FEL) for type B
23
fl ue
=
30 meters
Each fl ue accessory such as bends and straight lengths restrict the fl ue system and have a
FEL
which must
be added together to determine the total. Referring to the table above,
select a suitable fl ue system for the
particular installation requirement and then calculate the
FEL
of the system, this must not be greater than that
stated above.
The fl ue duct can discharge either vertically or horizontally by selection of the correct fl ue terminal. The fl ue
pipe can be fi tted with 90 and 45 degree bends as well as extensions.
Example C

:
A fl ue system that uses ten straight lengths, three 90° bends, two 45

bends and a horizontal
terminal.

WARNING
Flue type B
23
- The air inlet connection to the appliance must be fi tted with a Debris Guard. Air is
drawn from the room or compartment in which the heater is installed and therefore the room or
compartment
must be ventilated
(see 4.12.1 on P27)
WARNING
Flue type C
53
- The terminals used for the supply of air and for combustion products must not be
installed on opposite walls of a building
When the combustion fl ue system required is longer than 5m, it is recommended that a separate
system to capture excess condensation formed inside the fl ue is fi tted.
