3. Safety distances
Firewall
Ensure that the minimum safety distances are fullfiled
(
FIG 1
).
When connecting a steel chimney to the top outlet use
the security distances required by the manufacturer.
Important! When placing the insert on
a combustible floor, a steel plate of at least
0.7mm must cover the entire floor surface inside
the surround. Any flooring made of combustible
material, such as linoleum, carpets etc. must be
removed from underneath the steel plate.
4. Assembly
FIG 3 - to FIG 12
Assembling and adjusting the legs FIG 3
The insert is delivered with adjustable legs. The legs
are mounted on to the insert using the added bolts and
washers.
Fasten the screws on to the insert with a 13 mm
wrench.
Adjust legs to the desired height before returning the
insert to an upright position
(do not tilt the insert)
.
The height varries according to the surround.
Air inlet FIG 4
Assemble air inlet connector to the insert body with pro-
vided fasteners and tool, as shown on the drawing.
Flue colar FIG 5
The insert is equipped in connector which enable top
flue chimney connection.
Assemble connector with provided fasteners and tools.
Attention! Our inserts are prepared for connecting
the smoke pipe on the outside of the flue collar
Ø150.
*
Alternative versions of the flue collar exist due to
National requirements. For the flue connection to the
chimney, follow the recomenndations from the chimney
manufacturer.
The insert expands when in use, and for
this reason the surround must NEVER rest
on the insert, but have a gap of about 3 mm.
The insert must neither rest on the bench plate or
against the sides. It is recommended to dry stack
the surround in order to adjust the insert prior
to perforating the chimney for the flue connection.

Operation*
Intermittent*
* Intermitent combustion refers to normal use of a fireplace,
i.e. new wood is inserted when the previous load has burned
down to ember
Warning: If the requirements for ventilation are
NOT complied with, the cooling airflow around the
product will be considerably reduced and
the product can overheat.
This can cause a fire.
