In most installations a back panel will be required, this will also need a minimum fire resistance rating of Class O
(100 C).
Check that the chimney and flue structure are sound and conform to the following flue requirements:
1. A conventional brick or stone chimneys with a minimum effective cross sectional dimension of 225x225 mm. A
lined flue with a minimum diameter of 175 mm having a chair brick and throat forming lintel conforming to BS
1251 or a builders opening measuring 550 mm high x 400/470 mm wide with a sufficient depth for debris
collection. If a chair brick is fitted, a minimum depth requirement for the appliance is shown in Figs 2 & 3, if
insufficient depth is available, the chair brick will have to be removed.
2. A twin walled metal flue box manufactured to BS 715 with a twin walled 125 mm diameter flue and a minimum
effective flue height of 3 metres. See Figs 4 & 5.
3. 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 6 - 8.
Dampers, register plates or incorrect flue terminals, must not restrict the flues listed above. 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, which may cause spillage to occur.
