OPERATING INSTRUCTIONS

www.heta.dk

Congratulations on your new stove. We

are sure that you will be happy with

your investment, especially if you follow

the advice and instructions we have put

together in these operating instructions.

The Scan-line 10/20/30 20B/30B have

been approved according to the EN

13240 / NS 3058.

Approval means that consumers can be

sure, that the stove meets a range of

speciﬁcations and requirements inten-

IMPORTANT

1. Make sure there is adequate provision

to sweep the chimney.

2. Make sure there is adequate ventila-

tion to the room.

3. Please note that any extraction fans

operating in the same room as the

wood-burning stove can reduce the

chimney draft – which may have an

adverse effect on stove combustion

properties. In addition, this may cause

smoke to be emitted from the stove

when the ﬁring door is opened.

4. It must not be possible to cover any

air vents.

The oor

It is essential to ensure that the ﬂoor

surface can actually bear the weight of

the stove and a top-mounted steel chim-

ney, 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 regulations.

The chimney connection

The chimney opening must follow na-

tional and local regulations. However,

the area of the opening should never

be less than 175 cm

, which corresponds

to a diameter of 150 mm. If a damper is

ﬁtted in the ﬂue gas pipe, there must al-

ways be at least 20 cm

of free passage,

ded to ensure that the materials used

are of good quality, that the stove does

not adversely affect the environment,

and hat it is economical to use.

With your new stove you should have

received the following:

a. Operating instructions

b. A stove glove

Safety clearances

Stoves must always be installed in line

with national and, if applicable, local

regulations. It is important to abide by

local regulations 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 ﬂammable 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 re-

commend leaving a gap of at least 5 cm

to facilitate cleaning behind the stove.

The minimum distances to ammable

material are stated on the boiler plate

and are listed in the table on page 6.

Warning

A stove gets hot. (In excess of

90 degrees) Take care to ensure

that children and elderly or

inrm people cannot come into

contact with it.

Combustible materials should

not be stored in the compart-

ment below the ashpan.

INSTALLATION INSTRUCTIONS

even when the damper is in its “closed”

position. If local regulations permit, two

contained ﬁreplaces can be connected

to the same chimney. However, you must

abide by local regulations regarding the

distance between the two connections.

Wood-burning stoves must never be

connected to chimneys that are also

linked to a gasred 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 thim-

ble 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 thim-

ble 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 stove directly to a steel chimney,

we recommend ﬁtting the chimney

tube inside the ﬂue gas spigot 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 national and

local regulations regarding distance to

ﬂammable material must be followed.

It is important that the chimney is ﬁtted

with roof support so that the top panel

of the stove is not required 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 satisfactory combustion in stoves

of this kind is 12 PA. However, there

will still be a risk of smoke emission if

the ﬁring door is opened during power-

ful ﬁring. The ﬂue gas temperature at

nominal output is 257°C when expelled

to an exterior temperature of 20°C. The

ﬂue gas mass ﬂow is 6 g/sec. The chim-

ney

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 condi-

tions also have an effect on the ability

of the chimney to generate appropriate

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 summer, 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 conditions can be com-

pensated 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.

- 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 res

In the event of a chimney ﬁre – which

often results from incorrect operation

or protracted ﬁring with moist wood –

close the door and shut off the seconda-

ry/start-up air supply to smother the ﬁre.

Call the ﬁre department.

Lighting and combustion

To open the ﬂow of secondary air, use

the operating handle at the front of the

stove. The secondary airﬂow is com-

pletely 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 position, ﬁg. 2.

INSTRUCTIONS FOR USE

First ring

The stove has been treated with a heat-

resistant coating which hardens at a

temperature of approximately 250 ºC.

This hardening process causes the

production of smoke and malodorous

fumes, so the room must be very well

ventilated.

During the ﬁrst ﬁring, which should be

carried out using approximatly 1.6 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, pressure-

impregnated wood or chipboard, as

these materials can emit poisonous

fumes and smoke. Correct ﬁring using

well seasoned wood provides optimal

heat output and maximum economy. At

the same time, correct ﬁring prevents

environmen-tal damage in the form of

smoke and emmissions and also reduces

the risk of chimney 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 diame-

ter of more than 10 cm should be split

before storing. The pieces of ﬁrewood

should be of an appropriate length (ap-

prox. 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.

Optimal ring

To achieve optimal ﬁring and the hig-

hest possible effect, it is important to

make sure that the air supply is used cor-

rectly. As a general rule, the secondary

air is to be used to control the ﬁre to ig-

nite the ﬂue gases. This produces a high

effect and keeps the glass panel com-

pletely 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 mechanism and

secondary air intakes are closed complet-

ely. 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 con-

stantly. This will

normally occur

within 30 to 60 seconds.

A risk of explosion can possibly arise if

too much wood is placed in the stove.

This may result 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 lying 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.

Lighting

To ignite the fuel, use ﬁre lighters, small

parafﬁn ignition 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.

Rering

You should normally reﬁre the stove

while there is still a good layer of embers

Distribute the embers across the bottom

grate, place pieces of fuel (max. 2 kg) on

the embers in a single layer perpendicu-

lar to the ﬁring opening. Close the ﬁring

door and fully open the start-up me-

chanism. The wood will then ignite very

quickly – i.e. in 30 seconds or 1 minute.

When the wood is burning with a steady

ﬂame, close the start-up mechanism.

Then adjust the secondary airﬂow to

the

level required. For nominal operation

kW), the secondary air supply should be

70% open. When ﬁring, take care not

to place the pieces of fuel too close-ly

together, as this will result in poor com-

bustion 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 smal-

ler volumes of wood at each ﬁring, and

apply a lower airﬂow. However, remem-

ber that the secondary combustion air

supply must never be shut off complet-

ely during 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 generates ﬂames

OPERATIONAL PROBLEMS

The chimney must be swept at least

once a year, we recommend the use of

a NACS (national assoc

iation of chimney

sweeps) registered chimney sweep. In

the event of smoke or malodorou

s fumes

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 ensu-

re that it is possible to regulate the ﬁre.

Please note, however, that chimney draft

is dependent on the weather conditions.

In high winds, the draft can become so

powerful that it may be necessary to ﬁt

a damper in the ﬂue gas pipe to regula-

te 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.

If 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.

MAINTENANCE

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 cleaner.

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.

Warning

Any unauthorised modiﬁcation

of the stove and any use of

non-original spares will void the

guarantee.
