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.

Distance to Combustible Material
For combustible material, such as combustible walls, furniture, etc., for reasons
of safety a number of minimum distances apply.
The following minimum distances apply:
A= 700 mm, B= 4000mm C: 30 mm, 1000 mm in front of the stove
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.

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 shall be a diameter of min. 150 mm
(interior dimension) in steel chimneys and a minimum diameter of 175-180 mm
in brick chimneys or chimneys of ceramic units as their inside surfaces will
frequently be rough and offer resistance.
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.
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
Note that it is a matter of a heavy stove, and it should be ensured that the floor
has the carrying capacity required.

When placing your new Lotus stove on the floor, it should be put on a non-
combustible plate, for instance of steel or stone material. This plate should be
so large as to 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.

Kindling and Current Stoking at EN Test
1. Put about 2.1 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.
2. Close the door ajar, leaving an aperture of appr. 3 cm. Open the ignition vent
control under the door all the way (pulling it out fig. A) and open the register
on top (pulling it to the right Fig. B). Leave the stove like this for about 8-10
minutes before closing the door completely.
3. When the flames are stable and the chimney is warm, push in the air control
out of the ignition mode and regulate the fire normally.
4. 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 to leave them in an even layer.
5. Put two pieces of wood into the stove, about 1.2 kg. Put all the pieces at the
bottom of the stove, parallel with the stove front, at an equal distance to the
stove sides and at a reciprocal distance of appr. 1 cm. The front piece will
ignite best if it has one split side facing the door, and one down in the
embers. Close the door immediately and completely.
6. Open the air vent control entirely, and after about two minutes set the air vent
control as to be about half 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”. Regulation of the air vent control takes
some experience, but after a little while a natural rhythm for the fire will be
found.
7. When the wood has burned down to embers (after about one hour), start all
over from item 5.
When firing in the stove, the door should be kept closed. The only exemptions
from this rule are for kindling and for stoking.

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
be inspected for blocking prior to rekindling.
Cleaning of Stove
All Lotus stoves have been factory surface treated with original Senotherm
lacquer in ‘coke’ 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.
The soapstones may be cleaned –not using rough detergents –but a little spray
for window cleaning. Any small scratch may be cautiously polished down using
very fine sandpaper.
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 changed
as required as it is essential to good combustion and to a clean pane that your
stove is tight.
The insulation plates are classified as “wear and tear” parts which will require
to be exchanged after some years. The wear time will depend on the individual
use of your product. In case it is necessary to take out the insulation plates, this
is done in following order.

A. Baffle plate
B. Back plate
C. Bottom front left
D. Bottom front right
E. Bottom plate left F. Bottom plate right
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, conifers, 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.
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 15-
20%). 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. 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 exercise.
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 the ash pan out a little and opening the grate a little to get your 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.
