INSTALLATION - False Drywall Chimney Breast & Twin Wall Flue
10
1. Construct a false chimney breast using a suitable
non-combustible steel frame construction kit (Fig. 15).
2. Ensure that there are two vertical steel battens
placed to allow the flange of the fire box to be screwed
to them (Fig. 15).
3. Fix a horizontal batten at the desired height for the
fire box to sit on. Fix the second horizontal batten high
enough so that the firebox can slide into the opening
(Fig. 15).
Under no circumstances should combustible
materials such as wood be used in the construction
of the false chimney breast, due to the high
temperatures that the fire box reaches.
4. Construct a suitable non-combustible platform large
enough to sit the fire box on and level with the top of
the lower horizontal batten (Fig. 16).
Under no circumstances should combustible
materials such as wood be used in the construction
of the platform, due to the high temperatures that
the fire box reaches.
5. Slide the fire box into position and fix through the
holes in the flange into the chimney breast framework
using self drilling screws (Fig. 17).
6. Locate the twin wall flue pipe on to the flue adapter
on the top of the fire box. Drill three holes with a 3mm
bit around the flue tube and secure using the three self
tapping screws provided (Fig. 17).
7. Seal any gaps with fire cement.
8. Secure the fire box to the wall using the fixing holes
provided in the fire box flange (Fig. 18).
