Fire Surround and Opening Requirements
Check that the chimney and flue structure are sound and conform to the following flue requirements:
a) A conventional brick or stone chimney with a minimum effective cross sectional dimension of
225x225mm. A lined flue with a minimum diameter of 175mm having a chairbrick and throat forming lintel
conforming to BS 1251 or a builders opening measuring 560mm high x 400mm wide with a depth of 185mm
minimum for debris collection. If a chairbrick is fitted, a minimum depth requirement for the fire is shown in
fig 2.
b) A twin walled metal flue box manufactured to BS 715 with a twin walled 125mm-diameter flue and a
minimum effective height of 3 metres. See figs 3&4.
c) A pre-cast flue conforming to the requirements of BS 1289 Pt 1 1986 and BS 1289 1975 including properly
constructed pre-cast flues with a cross sectional area of 13000sq mm. See figs 5&6.
Important
Dampers, register plates or incorrect flue terminals, must not restrict any of the above flues. The flue must
only service a single appliance and not have any branches or traps that may impede the natural draught. Any
flue damper plate or restrictors shall be removed or fixed in the fully opened positions.
The front and base of the fire opening must be flat and square to ensure a good seal with the appliance; this is
to ensure that there is no reduction in draught through the fire that may cause spillage to occur.
Clearance to Side (timber surrounds etc)
Minimum clearance required to any combustible material to the side of the appliance must be 15Omm. Fig 1.
Clearance to Shelves
Minimum clearance to the underside of a 15Omm deep combustible shelf from the hearth must be 79Omm.
Add 12.5mm to this clearance for every 25mm increase in depth of shelf. Fig 1.
