Flue System Installation
Flue outlet (spigot) dimensions:
Internally = 8 mm
Externally = approx. 3 mm
When installing the vent, it is important to adhere to
national and local regulations that apply. Only one appli-
ance may be connected to the vent system.
The vent system must terminate above the roof.
The vent system and the flue pipe components must
be fastened to the stove with screws.
Minimum height of the chimney is approx. ,5 m (7’)
and maximum height should not be more than approx.
0,7 m (35’). (When installation is at or above a height of
approx. 60 m (000’), the chimney’s height must be at
least approx. 3,7 m (’.) measured from the flue outlet. If
the chimney has to move through a horizontal distance,
make sure to use 45º or 90 º bends.
Max. number of 45º bends = 4
Max. number of 90º bends = 3
It is permitted to move the chimney a total of approx.
, m (4’) horizontally.
An exhaust hood (terminal, cowl or rain cap) must be
mounted at the chimney’s termination point . After fit-
ting of the vent system and installation of the appliance,
carry out a smoke test on the flue as described in the
relevant section. If the appliance shuts off in operation
for no apparent reason (especially during windy or stormy
conditions) and will not relight, it is possible that the flue
system safety switch has operated. Allow the appliance
to cool down and relight. Any obstruction to the flow of
exhaust gases up the flue can cause this switch to operate
thereby making the situation safe. If the appliance cuts
out repeatedly, do not continue to use the appliance and
seek flue checking and service from qualified personnel
before re-using the appliance.
Closure Plate Installation
It is permissible to install this appliance using a closure
plate installation similar to traditional outset gas fires.
See diagrams ( E-F) on page 8. The British Standards de-
tailing this type of installation are BS587 pt and BS5440
pt . The appliance and flue must be sound and if used
with solid fuel or oil appliances it must be swept prior to
installation. There must be no other openings other than
the exit from the top of the flue and the opening into
which the appliance is being installed. All cracks, holes,
underfloor air vents etc must be removed and sealed fully
before installation continues. A proprietary metal flue box
complying with BS75 is a suitable appliance opening.
