USE OF EXISTING FLUES OR CHIMNEY’S

An existing flue pipe or chimney that has proven to
be  satisfactory  when  used  with  another  solid  fuel
appliance  can  normally  be  used  for  this  appliance
provided  that  its  construction,  condition  and
dimensions are acceptable.  Flues that have proved
to  be  unsatisfactory,  particularly  with  regard  to
down draught, should not be considered for venting
this  appliance  until  they  have  been  examined  and
any faults corrected.  If there is any doubt about an
existing  chimney  a  smoke  test  should  be  carried
out.

Before  connecting  this  appliance  to  a  chimney  or
flue  pipe  which  has  previously  been  used  with
another  flue,  the  chimney  or  flue  pipe  should  be
thoroughly swept.

When  a  chimney  is  not  to  be  lined  a  suitable  void
should  be  provided  at  the  base  to  contain  any
debris which may fall from the inside wall, so as to
prevent  the  debris    from  obstructing  the  appliance
flue outlet.  (Removal of debris should be facilitated
by the provision of an access door). 

VENTILATION 

COMBUSTION 

AIR

REQUIREMENTS

It is imperative that there is sufficient air supply to
the cooker in order to support correct combustion.

The  air  supply  to  this  appliance  must  comply  with
B.S. 8303: Part 1.

A  permanent  air  entry  or  opening  with  a  total  free
area  of  at  least  550mm

2

per  kW  of  rated  output

above  5kW  shall  be  provided  but  in  no  case  less
than 6500mm

2

.  Where a flue draught stabiliser is

used  the  total  free  area  should  be  increased  by
300mm

2

for each kW of rated output as per Building

Regulations Part J.

If  there  is  another  appliance  using  air  fitted  in  the
same  or  adjacent  room,  it  will  be  necessary  to
calculate additional air supply.

All  materials  used  in  the  manufacture  of  air  vents
should be such that the vent is dimensionally stable
and corrosion resistant.

The  effective  free  area  of  any  vent  should  be
ascertained  before  installation.    The  effect  of  any
screen should be allowed for when determining the
effective free area of any vent.

Air vents direct to the outside of the building should
be located so that any air current produced will not
pass through normally occupied areas of the room.

An  air  vent  outside  the  building  should  not  be
located  less  than  the  dimensions  specified  within
the Building Regulations from any part of any flue 

terminal.  These air vents must also be fire proofed
as per Building Regulations.

Air vents in internal walls should not communicate
with bedsits, toilets, bathrooms or rooms containing
a shower.

Air  vents  traversing  cavity  walls  should  include  a
continuous duct across the cavity.  The duct should
be installed in such a manner as not to impair the
weather resistance of the cavity.

Joints  between  air  vents  and  outside  walls  should
be  sealed  to  prevent  the  ingress  of  moisture.
Existing air vents should be of the correct size and
unobstructed for the appliance in use.

If there is an air extraction fan fitted in the room or
adjacent  rooms  where  this  appliance  is  fitted,
additional  air  vents  will  be  required  to  eleviate  the
possibility  of  spillage  of  products  of  combustion
from the appliance/flue while the fan is in operation.

Where such a installation exists, a test for spillage
should  be  made  with  the  fan  or  fans  and  other
appliances  using  air  in  operation  at  full  rate,  (i.e.
extraction  fans,  tumble  dryers)  with  all  external
doors and windows closed.

If spillage occurs following the above operation, an
additional  air  vent  of  sufficient  size  to  prevent  this
occurrence should be installed.
