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.
We recommend a minimum of 5 cm to facilitate
air circulation around the stove.
The minimum distance to combustibles can be
found on the model plate provided with the sto-
ve or on page 13 of this manual.
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 12.
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). These
stoves can be installed on a 12 mm non com-
bustible hearth.
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 115 cm
2
, which
corresponds to a diameter of 121 mm. If a damper
is fitted in the flue gas pipe, there must always
be at least 20 cm
2
of free passage, even when
the damper is in its “closed” position.
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.
Connection to a brick chimney
Brick a thimble into the chimney and seat the
flue gas pipe in this.
The thimble and flue gas pipe must not penetra-
te the chimney opening itself, but must be flush
with the inside of the chimney duct. Joins bet-
ween brickwork, the thimble and flue gas pipe
must be sealed with fireproof material and / or
beading. Heta A/S stresses that it is of utmost
importance that this is done correctly with very
tight joints. As mentioned earlier, we recommend
that setup and installation be left to a profes-
sional Heta dealer.
