Flue System Installation
Flue outlet (spigot) dimensions:
Internally = 128 mm
Externally = approx. 131 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. 2,15 m (7')
and maximum height should not be more than approx. 10,7
m (35'). (When installation is at or above a height of
approx. 610 m (2000'), the chimney’s height must be at
least approx. 3,7 m (12'.) 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.
1,2 m (4') horizontally.
An exhaust hood (terminal, cowl or rain cap) must be
mounted at the chimney’s termination point . After fitting
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 oper-
ate 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 person-
nel 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 (1 E-F) on page 28. The British Standards
detailing this type of installation are BS5871 pt1 and
BS5440 pt 1. 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 propri-
etary metal flue box complying with BS715 is a suitable
appliance opening.
