Any encroachment on this will require an adequate risk assessment of this installation and
sufficient provisions made for future service and maintenance.
It is possible to fit the stove with less clearance around it
–
down to 50mm, but the non-
combustible material around it must be at least 150mm thick. This is normally achieved
when installing into a standard brick-built chimney breast with double thickness walls to
the rear and sides of the builder’s opening. Take care that the wall finish is suitable to
withstand temperatures of up to 400
o
C.
2.3.2 Hearths
Allow a hearth apron of at least 225mm at the front of the stove, 150mm on either side
and be a minimum thickness of 50mm. Care should be taken to secure the hearth and
ensure it is level when the stove is in its final resting position. If existing floors do not have
adequate load bearing capacity then a risk assessment must be completed taking into
account the loading of the installation whole.
2.3.3 Ventilation
If the room in which the stove is fitted has an air permeability of more than 5.0m3/(h.m2)
(typical of house built pre 2008) then on a satisfactory commission of the appliance no
additional ventilation is necessary.
Flues With No Flue Draft Stabiliser
When the room permeability is less than 5.0m3 /(h.m2) (typical of house or extension
built after 2008) and there is no flue stabiliser fitted this stove will require at least
2700mm2 of permanent ventilation.
Flues With a Flue Draft Stabiliser
When the room permeability is less than 5.0m3 /(h.m2) (typical of house or extension
built after 2008) and there is a flue draught stabiliser fitted then this stove would need a
minimum of 4250mm2 of permanent ventilation.
2.3.4 Top or Rear Flue
Remove the collar and accessory pack from the stove. The stove will arrive with the
blanking plate fitted to the rear. This can be removed if required allowing the collar to be
fitted for rear flue installations. The blanking plate when removed from the rear flue must
then be reinstalled to the top outlet.
