5.4.1 A. Built into masonry or an existing fireplace opening
The insert is primarily designed to be built into masonry or an existing fireplace opening.
The adjacent materials must be nonflammable.
A layer of wallpaper is normally considered nonflammable when applied to masonry.
A nonflammable floor protection must cover the floor at least 300 mm to the front of the
firing door and at least 150 mm to each side of the firing opening.
Please note that the floor must be capable of supporting the installation.
There are only spacing requirements when the stove is placed next to flammable materials as
following:
Distance to furniture 700 mm.
Right-angled distance to flammable sidewall 300 mm.
Mounting
Remove or fix any existing damper in the chimney in the open position. It is important that
there are a few millimeter between the insert box and the surrounding masonry. Otherwise,
the thermal expansion of the insert box may cause cracking of the masonry.
As an initial estimate, the dimensions of the insert opening in the masonry are 430 x 600 x
450 mm. (width x height x depth).
This will make the installation of the flue pipe easier, and in some cases, the chimney sweep
may require one.
T
The insert must be levelled with the
levelling screws. And the insert box must be
even and flush with the masonry.
The insert is connected to the chimney by a
125 mm in diameter flue pipe that is
fastened to the flue collar of insert. Seal
between the flue pipe and the masonry
chimney with refractory mortar. A thermal
expansion of the flue pipe may cause
cracking of the refractory mortar. Therefore,
it is important to use a wall bushing and
sealing cord.
If there is no cleaning door as shown in the
drawings, it may be advantageous to install
one.
