The current versions of BS1289 and BS EN 1806 recommend that there should be an air
space or insulation between the flue blocks and the plaster because heat transfer may cause
cracking on directly plastered flues.
However, generally this appliance is suitable for installations under all circumstances unless
there is a history of cracking problems, remember that faults such as cracking may be caused
by poorly built and restrictive flues and therefore is not the responsibility of the manufacture
of this appliance.
Any existing draught device situated under the fireplace must be sealed off.
The opening area must be non-combustible
.
The appliance requires a hearth with non-combustible surface of at least 300mm in depth and 12mm thick.

edge or fender 50mm high.
To enable the product of combustion to be cleared properly up the flue, the outlet at the back of the
appliance must have a 50mm minimum clearance between it and the back wall of the opening or any other
obstruction.
The area immediately above the outlet must form a smooth path into the flue.
The fireplace or builders open must be reduced to suite the appliance both side to side and the full depth
