Construction of a false chimney breast front.
•
Using 50mm K.D Sawn stud-work will provide the required rebate.
•
The vertical sides of the stud-work should not be less than 502mm from the centre of the firebox. The
horizontal stud-work should not be less than 764mm from the base of the firebox. This will ensure 50mm
minimum clearance from the sides and 110mm clearance from the top of the firebox is maintained.
•
An insulation material (20mm “Super lux” or equivalent) should be attached to the underside face of the
horizontal stud-work directly above the firebox assembly.
•
Line the opening with 12mm thick non-combustible material.
