-1000L
■
PROMAFOUR
®
-GLUE 1000
■
Standard mechanical screwdriver
■
Standard screws suitable for the rear wall material

Preparation
− Cover your floor and furniture with a blanket or other
protective material to avoid possible damage.
− Make sure that the floor and rear wall are in good
condition. They have to be free of moisture and mould,
combustible and loose parts.
− Equalise, straighten and level the floor and rear wall.
− Create sufficient secure and free workspace around
your fire.
Safety recommendations
Only use safe equipment, wear safety gloves, goggles,
shoes and a dust mask.
Important recommendations
A.
In installations with a timber wall, an air cavity has to be
provided by applying a 50 mm thick PROMASIL
®
-1000L
board directly to the PROMAFOUR
®
construction boards
at a minimum distance of 5 cm from the rear wall. Use
PROMAFOUR
®
-GLUE 1000 and self-tapping plaster-
board-screws on the outside of the PROMAFOUR
®
construction boards. Apply a sufficiently thick layer of
PROMAFOUR
®
-GLUE 1000 on the edges of the board
before fixing it using screws on the outside. The upper
and lower side of the insulating wall should be mounted
on metal profiles, which are fixed to the floor and ceiling
in advance. Provide sufficient ventilation in this cavity.
B.
Protect and insulate the floor by providing a small air
cavity between the wall and the board, as described in
point A.
C.
Even in the case of a freestanding stove, the floor and
rear wall have to be protected and insulated as described
in points A and B.
D.
In the case of a timber wall, use boards with a minimum
thickness of 50 mm. In case of a brick wall, boards with
a thickness of 30 mm are sufficient.
E.
Observe the installation and security instructions of the
firceplace/stove manufacturer.
Tip
− You can obtain a very fine saw-cut without burs by
using a DIA saw blade. This saw blade, which has been
developed especially to cut fibre-cement and calcium
silicate boards, is equipped with moulded teeth and
diamond plating. This type of saw blade also has a better
durability than ordinary saw blades. Contact Promat for
more detailed information.
− Cutting different materials with the same saw blade re-
duces its life span. We therefore advise you to use a fibre
cement saw blade only to cut fibre cement materials.
− It is advisable to insulate the rear wall behind a freestan-
ding stove also. PROMASIL
®
-1000L boards are the best
solution for this application.
