3.1 Builders opening and surround (continuing)
If the builders' opening is constructed out of non-combustible
composition board (Fibrelux) and you install the appliance without a
mantel then:
- Ventilate the space above the appliance (min. 1000 mm
2
).
- Always fit the DC convection set.
- The plaster of the outside has to be resistant to a high
temperature. Use therefore the plaster materials especially made for
this, to prevent discoloring (min. 100 °C temperature resistant).
If the appliance is to be fitted against a wall with combustible
cladding, the cladding must be removed from the area covered by the
surround.
The minimum height from the top surface of the fire to the underside
of any shelf made from wood or other combustible materials is as
follows:
- For a shelf up to 150 mm deep – Minimum height = 350 mm
(fig. 1).
- If the shelf depth is greater than 150 mm add 50 mm to the upper-
clearance height for every 25 mm increase in shelf depth.
- Side clearance = Minimum distance from the side of the fire frame
to combustible material = 150 mm.
