Introduction
Congratulations on your new Lotus Wood Stove
We sincerely trust that your Lotus Wood Stove will bring many happy hours
for you. However, to benefit fully from your investment, you should read these
instructions thoroughly. They contain some specific advice on how to benefit
fully from your stove – now, and in the years ahead. So, like all other directions
for use, keeping them in a safe place would be a good idea.
Lotus Wood Stoves are based on a long tradition; the first productions were
way back in 1979. Our production is now run in Langeskov on Funen in
Denmark, and is exported to a great many European markets. Our stoves are
produced to sound Danish tradition, and have given their owners good and
reliable service for years. So, once again, congratulations on your new Lotus
wood stove. We feel certain that putting your Lotus wood stove in operation
will inaugurate a warm and cosy beginning of a new home life for you.
This stove is intended for ”intermittent combustion”, a process achieved by
following the instructions of the guide below under ”Use of Stove”.
Mounting of Stove
Before your new stove will be ready to exude warmth and cosiness, you should
read these pages thoroughly. Pages reviewing the requirements for the
mounting and for the surroundings. Reference is also made to the fact that local
regulations, including those referring to national and European standards,
applying at all times must be met for the installation of your wood stove.
A warning should also be issued against any unauthorized change of your wood
stove. It should be added that the surfaces of your wood stove will become hot.
Lotus recommends that your stove be mounted by an authorized Lotus
distributor or by a fireplace service man recommended by an authorized Lotus
distributor.
NOTE: Your stove may not be put into use until the installation has been
approved by the local chimney sweep.
Further, please note that any air grates are to be placed so as not to block.
Distance to Combustible Material
For combustible material, such as combustible walls, furniutre, etc., for reasons
of safety a number of minimum distances apply. The following minimum
distances apply:
Uninsulated Pipe
Insulated Pipe
A: 200mm
B: 200mm behind stove
C: 400 beside stove
900mm forward
A: 200mm
B: 125mm behind stove
C: 400mm beside stove
900mm forward
If a non-combustible board is laid under the stove, it must protrude at least
30 cm off in front of the stove and 15 cm off at each side of the fireplace
opening.
Distance to non-combustible material
For non-combustible material, there should be a distance of 80-100 mm in order
that the stove may release and distribute the heat while you may clean on and
around the stove.

Smoke Control Areas
UK Clean Air Act 1993
The Lotus Liva stove has been exempted under Section 21 of the Clean Air Act
1993 for use in Smoke Control Areas when burning wood logs.
Chimney
A good draught in your chimney is paramount to how well a stove will burn.
Note that there should be access to cleaning doors.
The effective height of your chimney should typically range between 3.5 and
4.5 metres. Effective height is to be understood as the distance from the stove
top to the top of the chimney. The inside diameter of the chimney should be
min. 150 mm (inside dimension).
All joints and connection points shall, of course, be tight, and the chimney shall
be able to provide a draught of a min. 1.2 mm water column (12 Pa), though
preferably a little more.
The wood stove may be connected to chimneys which are also used for other
purposes. To this end, the specific local conditions shall be assessed by a fitter
and/or chimney sweep.
Register
If your chimney has a register, it should have a forced aperture of min. 20 cm2.
Mounting of Smoke Baffle Plates
Below, it has been shown how the smoke baffle plates are to be placed when
viewing a section in the stove from the side.
Stålrøgvendeplade
Steel smoke baffle
Skamolrøgvendeplade
plate
Skamol smoke baffle
plate
Each smoke baffle plate is to be removed separately. Both smoke baffle plates
are removed by lifting up at one side after which they may come clear at the
other side and be taken down into the combustion chamber and out of the door.
Similarly, they are put in place by leading them up slanting-wise at one side,
and then at the other side, and they are then put into place in the middle.
Combustion Air Supply
It is important for good and clean burning that adequate air be supplied to the
fire. To allow for this, it is, however, a condition that air be supplied to the
room in which the stove has been set up.
Certainly most rooms will have sufficient air, not least if some of the doors
between the rooms of the house are open. In special cases, an air valve may
have to be put in the exterior wall of the room in which the stove has been put
up.
Floor
When placing your new Lotus stove on the floor, it should be put on a noncombustible plate, for instance of steel or stone material. The plate should be so
large that it will reach a minimum of 30 cm in front of the stove, and 15 cm at
each side of the fireplace opening.
Chimney Sweep
When your new stove has been mounted, do remember to report the installation
to the chimney sweep. For one thing, the installation will have to be inspected,
and the chimney should also be cleaned by the chimney sweep in the time
ahead.
Use of stove
Below, the procedure applied at the stove testing by Teknologisk Institut – The
Technological Institute – has been reviewed. This is the procedure generating
optimal combustion on the particular chimney.
Wood quantity and register setting may be varied as individually required for
heating and the draught of the particular chimney. The stove has been tested
with birch wood of a humidity of appr. 18%.
Kindling and Current Stoking at EN Test
1. The ash pan as well as the grate must always be closed completely, also when
kindling.
2. Put about 2 kg kindling wood into the bottom of the stove, stacked crisscross
like a log house. Put 2 fire-lighters in the middle, and ignite them.
3. Close the door ajar, leaving an aperture of appr. 3 cm. Open the register
under the door completely (turning it to the right). Leave the stove like this
for about 8-10 minutes before closing the door completely and turning the
handle into locked position
4. The register is damped as required during the kindling.
5. When the fire has burned down to embers (no more flames), open the door
gently so as not to whirl out the embers. Spread out the embers cautiously
using a poker so as to leave them in an even layer.
6. Put three pieces of wood into the stove, totally about 1.7 kg. The foremost
piece will ignite best if it has a split side facing the door, and one down in the
embers. Close the door immediately and completely.
7. Open the register entirely, and after about two minutes set the register so as
to be about one third open. Just how open the register should be may vary
with the draught of the particular chimney but the flames should now
stabilize into a “calmly burning fire”.
8. When the wood has burned down to embers (after about one hour), start all
over from item 5.
Slow Combustion
On a proper layer of embers feed a fair quantity of wood (3.0 – 3.5 kg
distributed on 3-5 pieces of wood – not one or two big logs). When the fire has
caught on well, adjust the air down. Never adjust down more than still leaving
clear, lasting flames. When this fire has burned down, the period up to the next
stoking may be stretched further by closing the register entirely so that cold air
will not be pulled through the stove.
Adjusting the air supply down too early, or if it is generally too small, will
cause a poor rate of efficiency and a too high emission level to the detriment of
the environment.
Ashes
Ashes may be discarded in the waste bin for refuse collection. The ashes should
always have cooled for 24 to 48 hours before being thrown into the waste bin as
there may otherwise still be embers that may ignite waste or the waste bag.
Sound Advice
Kindling after a protracted interval
If your stove has not been used for some considerable time, the chimney should
b inspected for blocking prior to rekindling.
Cleaning of Stove
All Lotus stoves have been factory surface treated with original Senotherm
lacquer in ”coke” or ”grey” colour. Due to this treatment, the stove will, during
the first kindlings, exude a special odour but that will vanish after a few times.
Good airing to be provided. The surface is maintained by brushing it using a
soft, long-haired auto brush or by using the vacuum cleaner with a brush.
Your stove should also be cleaned inside regularly. Ashes, soot, and any tar
residues are to be removed from pane and combustion chamber. Smoke baffle
plates should be dismantled regularly to remove soot and dirt which will
frequently settle behind the plates. Check at the same time whether there is free
passage to the chimney. The ash pan should also be emptied regularly as
required. The ashes from the wood stove may contain embers long after the
stove was used last time so always put the ashes in a fireproof bucket prior to
removal. Do remember that your stove should be cleaned in cold condition
only.
Chimney Fire
In case of a chimney fire, doors and register should be shut so as to cut off the
oxygen supply. Relevant authorities etc. may be called if necessary.
Stove Maintenance – use original spare parts only
Packings may seem to look nice; they will, however, collapse in the heat,
thereby losing their ability to keep your stove tight. Packings should be
replaced as required as it is essential to good combustion and to a clean pane
that your stove is tight.
The shaker grate may in extremely rare cases become worn or crack after use
and may also be easily replaced. Lift the grate and the frame a couple of cm,
release from draw bar, and replace by a new one. The actual frame holding the
grate may also be easily replaced as it lies loose in the Skamol.
The combustion chamber covering may break or become worn. The panels
are made of vermiculite, an insulation material. When worn, the material is to
be replaced not later than when the panels have a thickness of appr. 1.5-2.0 cm.
The material is slightly porous. To prevent breaking of the panels it should be
ensured that the board is not thrown but laid in the middle of the combustion
chamber. If you happen to break a Skamol panel, this will not have any impact
on the insulating effect of the panel.
Painting of your stove using Senotherm spray may cover stains or small
scratches from kettles or other. Heavy damage to be ground with fine steel
wool, vacuum cleaned, and then sprayed. Shake the spray can very heavily, and
spray on at a distance of 15-20 cm. It is most important that your stove will be
out of operation and quite cold before you use your spray, otherwise heavy
damage may be inflicted on account of fire risk.
Kindling Wood
Kindling wood is the designation for finely split small wood/sticks some 20 cm
long and having a diameter of 2-3 cm.
Wood
Birch, beech, oak, ash, elm, as well as fruit trees are all suitable for being
chopped into firewood.
Pressure impregnated wood, chipboard, coloured leaflets or glazed paper are,
however, not suitable in a stove. They will develop hydrochlorid acid or heavy
metals much to the detriment of your stove and to the environment.
Exemption of the Liva for use in a smoke control area applies when burning
untreated wood only.
Wood for your Lotus stove should have a diameter of 7-9 cm and be max. appr.
30 cm long as it will otherwise come too close to the stove sides (at the DS
testing 25 cm long wood has been used). The most important aspect of good
combustion is that your wood will be appropriately dry (of a humidity of 1520%). If your wood is too wet, making it burn will be hard, the chimney
draught will not occur, there will be a lot of smoke, and utilization will be low
as water will need to evaporate first. This is certainly harmful to the
environment and will cause a high level of emission. Further, it may cause
damage to your stove and chimney by way of shining soot and tar coverings.
“Worst Case” would be a chimney fire. If your wood is far too dry, it will burn
too quickly. Frequently the gases in the wood will be released quicker than they
will burn, and some part of these will go up the chimney unburned. Thus
yielding a lower rate of utilization and harming the environment.
So it is a matter of a balance which is, however, reasonably easy to find with a
little practice.
Also please refer to the comments below under Storage.
Storage of Wood
The best storage of the wood is under roof though still with good airing, for
instance in a car port or under a shed roof. Preferably put your wood on a
wooden pallet or similar, clear of the ground. Fresh wood, sawn and chopped,
should preferably be left in this manner for one or two years depending on the
species of wood.
Items available in stove
In the stove, the present mounting and user instructions are available, as well as
a glove good for stoking.
Operating Trouble
In case of any operating trouble with your Lotus stove, you may find the cause
of that below. If not, please do not hesitate to contact your Lotus distributor.
Stove hard to control – burning too quickly
If your stove is new, check our guide.
If your stove is more than one year old, or if it has been used heavily, the
packings may have to be replaced. If the packings are on for too long, the heat
will cause the packings to lose their ability to keep your stove tight.
Stove drawing badly after installation
Check that the mounting instructions have been followed. In particular,
conditions around the chimney may cause trouble. Are the diameter and the
length OK, is it tight, are the flue pipes and the transitions tight? A chimney
sweep may have to be contacted to remedy the problem as the chimney may be
clogged.
Smelling of Smoke and Soot
This may be due to wind down draught in the chimney and will mostly occur in
certain wind directions. The chimney may be too short in relation to the roof
ridge, or trees may have grown up and may be causing turbulence.
Your stove is hard to make burn and may go out
There may be a number of reasons for this. The most typical ones are:
The register is not open enough.
The wood is too wet.
The chimney draught is too small; it may be clogged or leaky.
The layer of embers was too small/no longer glowing and did not produce heat
enough to kindle the pieces of wood. A little primary air may be supplied by
pulling out the ash pan a little and opening the grate a little to get the stove
going again after which you close again completely.
Depending on the type of problem you may have to contact your Lotus
distributor or a chimney sweep.
