| How to Line a masonry fireplace
TECHNICAL SERVICES EMAIL:
1
Measure the three surfaces of the fireplace.
With older properties take several measurements
at different levels just to check how uneven the
wall might be.
2
You will need to cut the rear panel first as this is
the first one to be installed.
TIP
Always carry and stack PROMAFOUR® boards
carefully. Two people should carry a full board.
Each board should be carried on it’s edge, taking
care not to bend it as this can cause internal cracks
which may not show in normal conditions but when
heated the crack can expand. PROMAFOUR®
should be stored on flat surface in a well ventilated
room. NEVER store the boards on their side.
Carefully place your measurements on the
board prior to cutting.
3
Cut the PROMAFOUR® to the measurements
marked on the board for the three faces
of fireplace.
The installers in this guide have used a Festool
Plunge Saw with dust extractor which we
recommend for a straight cut but you can also
use a Jigsaw with woodworking saw blade.
TIP
We advise leaving a 2mm gap from the left and
right rear panel boards to allow for expansion when
heating. Please take this into consideration when
cutting.
Also leave a gap of between 1-2mm for the left and
right hand side panels from the back panel as this
will be glued later.
