Safety clearances

Stoves must always be installed in line with na-

tional and, if applicable, local

regulations. It is important to abide by local re-

gulations regarding setting up chimneys and

connection to same. The

refore, always consult

your local chimney

sweep before installation, as

you are personally responsible for ensuring that

the applicable regulations have been met

Distance regulations

A difference applies to installation next to ﬂam-

mable and non-ﬂammable walls.

If the wall is made of non-ﬂammable material the

stove can, in principle, be placed ﬂush against

it. However, we recommend leaving a gap of at

least 5 cm to facilitate cleaning behind the stove.

The minimum distances to ﬂammable mate-

rial are stated on the boiler plate and are li-

sted in the table on page 5.

Warning

A stove gets hot. (In excess of 90

degrees) Take care to ensure that

children and elderly or inﬁrm people

cannot come into contact with it.

Combustible materials should not be stored

in the compartment below the ashpan.

IMPORTANT

1. Make sure there is adequate provision to

sweep the chimney.

2. Make sure there is adequate ventilation to the

room.

3. Please note that any extraction fans opera-

ting in the same room as the wood-burning

stove can reduce the chimney draft – which

may have an adverse effect on stove combu-

stion properties. In addition, this may cause

smoke to be emitted from the stove

when the ﬁring door is opened.

It must not be possible to cover any air vents.

The ﬂoor

It is essential to ensure that the ﬂoor surface can

actually bear the weight of the stove and a top-

mounted steel chimney, if applicable. The stove

must stand on a nonﬂammable surface such as

a steel ﬂoor plate or a brick or tile ﬂoor. The size

of the nonﬂammable surface used to cover the

ﬂoor area must match national and local regu-

lations.

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 cm2, which

corresponds to a diameter of 150 mm. If a dam-

per is ﬁtted in the ﬂue gas pipe, there must al-

ways be at least 20 cm2of free passage, even

when the damper is in its “closed” position. If lo-

cal regulations permit, two contained ﬁreplaces

can be connected to the same chimney. Howe-

ver, you must abide by local regulations regar-

ding the distance between the two connections.

Wood-burning stoves must never be con-

nected to chimneys that are also linked to a

gasﬁred heater.

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 penetrate the chimney opening

itself, but must be ﬂush with the inside of the

chimney duct. Joins between brickwork, the

thimble and ﬂue gas pipe must be sealed with

ﬁreproof material and/or beading

Connection to a steel chimney

When ﬁtting a connection from a top-output st-

ove directly to a steel chimney, we recommend

ﬁtting the chimney tube inside the ﬂue gas spi-

OPERATING INSTRUCTIONS

Congratulations on your new wood stove, we are conﬁdent that you will be more than satisﬁed with

your new Heta stove. Especially if you follow the following advice and instructions.

Scan-Line 10/20/30 20B/30B have been approved according to the EN 13240, NS 3058, NS 3059

and A15 Austria. These approvals, means that the wood stove meets a variety of speciﬁcations and

requirements, ensuring it is made of quality materials, minimum environmental impact and that it

has an optimum fuel economy.

got so that any soot and condensation drops

into the stove itself rather than collecting on the

exterior surface of the stove. For connections to

chimneys that are run through ceilings, all natio-

nal and local regulations regarding distance to

ﬂammable material must be followed. It is im-

portant that the chimney is ﬁtted with roof sup-

port so that the top panel of the stove is not re-

quired to bear the entire weight of the chimney

(excessive weight may damage the stove).

Draft conditions

Poor draft may result in smoke being emitted

from the stove when the door is opened. The

minimum chimney draft to ensure satisfacto-

ry combustion in stoves of this kind is 11 PA.

However, there will still be a risk of smoke emis-

sion if the ﬁring door is opened during power-

ful ﬁring. The ﬂue gas temperature at nominal

output is 246°C when expelled to an exterior

temperature of 20°C. The

ﬂue gas mass ﬂow is

4,7 g/sec. The chimney

draft is generated by the

difference between the high temperature of the

chimney and the low temperature of the fresh

air. The length and insulation of the chimney,

wind and weather conditions also have an effect

on the ability of the chimney to generate appro-

priate under-pressure.

If the stove has not been used in a while, check

that the chimney and stove are not blocked with

soot, bird nests, etc., before using it.

Reduced draft can occur

when:

- The difference in temperature is too small – due to

insufﬁcient chimney insulation, for example.

- The outdoor temperature is too high – in sum-

mer, for example.

- No wind is blowing.

- The chimney is too low and sheltered.

- The chimney contains false air.

- The chimney and ﬂue gas pipe are blocked.

- The house is too airtight (i.e. when

there is an

insufﬁcient supply of fresh air).

- Poor smoke extraction (poor draft conditions)

due to a cold chimney or bad weather conditi-

ons can be compensated for by increasing the

airﬂow into the stove.

Good draft occurs when:

- The difference in temperature between

the chimney and outdoor air is high.

- The weather is ﬁne.

First ﬁring

The stove paint is fully cured from the factory,

but a minor unpleasant odour could still arise.

During the ﬁrst ﬁring, which should be carried

out using approximatly 1.24 kg. of wood, the

stoking door must be left slightly open and must

not be closed until the stove is cold. This is to

prevent the sealing rope sticking to the stove.

Fuel

Your new stove is EN approved for ﬁring

with

wood fuel. You must therefore only

burn clean, dry

wood in your stove. Never

use your stove to burn

drifwood, as this

may contain a lot of salt which can damage both

the stove and the

chimney. Similarly, you must not

ﬁre your

stove with refuse, painted wood, pres-

sure-impregnated wood or chipboard, as these

materials can emit poisonous fumes and smoke.

Correct ﬁring using well seasoned wood provi-

des optimal heat output and maximum econo-

my. At the same time, correct ﬁring prevents en-

vironmen-tal damage in the form of smoke and

emmissions and also reduces the risk of chim-

ney ﬁres. If the wood is wet and inadequately

seasoned, a large proportion of the energy in

the fuel will be used to vaporise the water, and

this will all disappear up the chimney. Thus it is

important to use dry, well seasoned wood, i.e.

wood with a moisture content of no more than

18%. This is achieved by storing the wood for

1–2 years before use. Pieces of ﬁrewood with

a diameter of more than 10 cm should be split

before storing. The pieces of ﬁrewood should be

of an appropriate length (approx. 25–30 cm) so

that they can lie ﬂat on the bed of embers. If you

store your wood outdoors, it is best to cover it.

- The wind is blowing strongly.

- The chimney is of the correct height: at

least 4.00 m above the stove and free of the

roof ridge.

Chimney ﬁres

In the event of a chimney ﬁre – which often re-

sults from incorrect operation or protracted ﬁ-

ring with moist wood – close the door and shut

off the secondary/start-up air supply to smother

the ﬁre. Call the ﬁre department.

Lighting and combustion

To open the ﬂow of secondary air, use the ope-

rating handle at the front of the stove. The se-

condary airﬂow is completely open when the

handle is to the left side position, ﬁg. 1. Shut

off the secondary airﬂow gradually by moving

the handle to the right. The supply is completely

shut off when the handle is to the right side po-

sition, ﬁg. 2.

Lighting

To ignite the fuel, use ﬁre lighters, small parafﬁn ig-

nition bags or small pieces of wood placed on the

bottom grate. Place larger pieces of wood on top

of this kindling material, at right angles to the ﬁring,

doors. Completely open the secondary air supply

and leave the ﬁring door ajar – i.e. approx. 1 cm

open. Once the ﬁre has taken a good hold of the

fuel and the chimney has heated up (after about

10 min) close the ﬁring door. We recommend that

you burn the entire ﬁrst ﬁring with the secondary air

supply fully open to make sure that the chimney is

thoroughly heated.

Reﬁring

You should normally reﬁre the stove

while there

is still a good layer of embers

. Distribute the em-

bers across the bottom grate, place pieces of

fuel (max. 2 kg) on the embers in a single layer

perpendicular to the ﬁring opening. Close the ﬁ-

ring door and fully open the start-up mechanism.

The wood will then ignite very quickly – i.e. in

30 seconds or 1 minute. When the wood is bur-

ning with a steady ﬂame, close the start-up me-

chanism. Then adjust the secondary airﬂow to

the level required. For nominal operation

(6,1kW),

the secondary air supply should be 38% open.

When ﬁring, take care not to place the pieces

of fuel too close-ly together, as this will result in

poor combustion and insufﬁcient exploitation of

the fuel.

Reduced burning

The stove is well-suited to intermittent use. If

you wish to operate the stove with reduced out-

put, simply insert smaller volumes of wood at

each ﬁring, and apply a lower airﬂow. However,

remember that the secondary combustion air

supply must never be shut off completely du-

ring ﬁring. It is important to keep a good bed of

embers. Gentle heat is released when the ﬁre

settles - i.e. when the wood no longer genera-

tes ﬂames and has been converted to glowing

embers.

Optimal ﬁring

To achieve optimal ﬁring and the highest pos-

sible effect, it is important to make sure that the

air supply is used correctly. As a general rule,

the secondary air is to be used to control the

ﬁre to ignite the ﬂue gases. This produces a

high effect and keeps the glass panel complet-

ely clear of soot as the secondary air “washes”

down over it. Please note that the stove will,

naturally, produce soot if both the start-up me-

chanism and secondary air intakes are closed

completely. This will prevent oxygen from being

drawn into the stove, and the viewing window

and other parts will become covered with soot.

If this situation is combined with ﬁring with wet

wood, the build-up of soot can become so

thick and sticky that the sealing rope can, for

example, become detached when the door is

opened the next day.

Risk of explosion

After you add new fuel, it is very

important that you do not leave the

stove unattended until the wood is

burning constantly. This will normal-

ly occur within 30 to 60 seconds.

A risk of explosion can possibly arise if too

much wood is placed in the stove. This may re-

sult in the production of large volumes of gas,

and this gas can explode if the intake of primary

and secondary air is insufﬁcient.

It is an advantage always to leave some ash ly-

ing in the bottom of the comb-

stion chamber.

Take care when emptying the ash pan, as

cinders can continue to burn in the ash for

long periods of time.

OPERATIONAL PROBLEMS

The chimney must be swept at least once a year,

we recommend the use of a NACS (national as-

soc

iation of chimney sweeps) registered chimney

sweep. In the event of smoke or malodorou

s fu-

mes being produced, you must ﬁrst check to see

whether the chimney is blocked. The chimney

must, of course, always provide the minimum

draught necessary to ensure that it is possible

to regulate the ﬁre. Please note, however, that

chimney draft is dependent on the weather con-

ditions. In high winds, the draft can become so

powerful that it may be necessary to ﬁt a damper

in the ﬂue gas pipe to regulate the draft. When

cleaning the chimney, soot and other deposits

may come to fall on the smoke plate. In cases

where the wood burns too quickly, this may be

due to excessive chimney draught. You should

also check to make sure that the door seal and

ashpan seal is intact and correctly ﬁtting.

f the stove it generating too little heat, this may be

because you are ﬁring with wet wood. In this case,

much of the heating energy is used to dry the

wood, resulting in poor heating economics and an

increased risk of soot deposits in the chimney.

Cleaning after sweeping the chimney and

replacing the stones. Fig 1-4

Maintenance

The surface of the stove has been trea-ted with

heat-resistant paint.

The stove should be cleaned with a damp cloth.

Any damage to the surface in the form of chips

or scratches can be repaired using touch-up

paint, which is available in spray cans.

Cleaning the glass

Incorrect ﬁring, for example using wet wood, can

result in the viewing window becoming covered

in soot. This soot can be easily and effectively

removed by using proprietary stove glass clea-

ner.
