2. Installation instructions
The stove installation must be in accordance
with national, European and possibly local regu-
lations. You must follow local regulations with
regard to installation of chimney and connection
to the chimney. We recommend that you let a
professional Heta dealer install the stove. Alter-
natively, you can ask the local chimney sweep
before installation. Be aware that it is always the
owner himself who has responsibility for ensu-
ring that applicable rules are complied with.
A modern stove places heavy demands on the
chimney due to the high efficiency. It may be
necessary to enhance or even replace an old
chimney.
Remember
1. Always ensure free access to any cleaning
doors in a chimney.
2. Always ensure ample fresh air to the room.
3. Exhaust/extraction fans in the house can re-
duce or create negative draft in the chimney.
Reduced draft can lead to the stove having
adverse combustion properties. It may result
in smoke coming out of the stove when the
door is open. A negative draft due to an
exhaust/extraction fan can cause the chim-
ney to work in reverse, drawing smoke into
the house because of the fan.
4. Any air vents must not be covered.
2.1 Distance Provisions
There is a difference between installation next to
flammable wall or non-flammable wall. If the wall
is made of non-flammable material, the stove in
principle may be placed flush against it.
Inserts are generally only intended for installing
in existing open fireplaces or in a wall built of non-
combustible material. There must be adequate
space between the wall and the convection
case. This is to avoid damage to the masonry/
wall when the stove expands when in use.
Minimum distances to combustible material fou-
nd on the table on page 20, the data plate, as
well as drawings. Pay special attention to the
distance to flammable floor (330 mm), which is
also applicable, although there is a steel/glass
plate on the floor. If the floor is made of, for ex.
concrete, tile or similar, there may not be com-
bustible materials for at least a depth of 330
18
mm, valid from the bottom edge of the door on
the insert.
Distances for installation see page 20.
2.2 floor
You must ensure that the floor can support the
weight of the stove and a top-mounted steel
chimney.
In front of the fireplace insert, the substrate
must consist of non-combustible material, for
ex. Steel/glass plate, stone or tile floor. The size
of the non-combustible surface must follow the
applicable national and local regulations. Pro-
tecting your floor from embers that may fall out
of the oven.
Distances see data table page 20.
Distance from flammable floor: 330 mm.
Pay special attention to the distance from flam-
mable floor, which is also valid even if there are
a steel, glass, stone or tile over flammable ma-
terials. It is the floor itself, which must be non-
flammable. (Concrete, tile or similar).
2.3 the chimney connection
The chimney opening must follow national and
local regulations. However, the area of the ope-
ning should never be less than 175 cm
corresponds to a diameter of 150 mm.
If a damper is fitted in the flue gas pipe, there
must always be at least 20 cm
even when the damper is in its "closed" posi-
tion.
If local regulations permit, two contained stoves
can be connected to the same chimney. How-
ever, you must abide by local regulations regar-
ding the distance between the two connections.
The stove must never be connected to
a chimney that is linked to a gas fire stove.
An efficient stove makes high
demand on chimney properties
– so always have your local
chimney sweep evaluate
your chimney.
