An integral flue spigot is fitted to all Variante
Air Heaters thereby allowing the flue to
connect directly to the heater.
The design of the flue must ensure that it
can be disconnected to allow for cleaning
and servicing.
All joints should be sealed between the
sections.
Warning
It is essential that the products of
combustion are flued to the outside of the
building.
Each heater must have its own separate
flue, with a flue diameter of not less than is
detailed in
section 7.2 within this manual.
WARNING
On VRABD 75 to 145 a Combustion Air
Plate is supplied as standard this MUST
be fitted in place of the combustion air
spigot if the heater is to be installed in
the flue only option
The flue assembly must comply with all the
relevant regulations regarding height and
materials, and must terminate with an
approved flue terminal.
Care should be taken to ensure that the flue
terminal is not situated in a high pressure
area, the proximity of buildings and other
obstacles which will influence this must be
taken into account, preferably at the design
stage.
All Variante Heaters are equipped with a
built in flue venter fan which prevents the re
circulation of combustion products,
consequently an external draught diverter,
barometric damper, or anti spillage system
must not be installed. Such devices are
unnecessary on the VRABD range of
heaters.
Horizontal flue installations: Distance
from heater connection to terminal must
not exceed the following length-
