Introduction
Congratulations on your new Lotus Fireplace Insert
We hope and believe that it will give you many a warm hour. But before you
may truly benefit from your investment, you should read this guide thoroughly.
It provides some specific advice as to how you will benefit the most from your
fireplace insert – now, as well as in the years to come. This is why this guide
would be worth while keeping, like all other directions for use.
Lotus may look back on a long tradition, making our first productions back in
1979. Our production is now run at Langeskov, and exported to many European
markets. Lotus products are made to a fine Danish tradition, serving its owners
faithfully for years. So, once again congratulations on your new Lotus fireplace
insert – making for a warm and cosy beginning of an all new home life for you.

Fireplace Insert Assembly
Before your new fireplace insert will be ready to exude warmth and a cosy
atmosphere, you should read these lines thoroughly, reviewing the requirements
for the assembly and the environment. Also, reference is made to all local
regulations, including those referring to national and European standards, to be
met in the installation of your fireplace insert.
The hole size required for assembly appears from the leaflet material as well as
the line drawings on the last page of these instructions.

Drawing is an illustration and applies to normal inserts and wide models
A. Holes used for fastening the insert to the base.
B. Set screws for adjustment of the insert in relation to the base.
C. Set screws for adjustment of the combustion champer in relation to the cabinet.

The potential for the building-in of fireplace inserts is vast; they may be built
into the wall, on the outside of the wall, and may be suspended on the wall.
Building-in shall take place in connection with non-inflammable materials only.
Virtually all installations are designed individually, and in all cases the distance
to inflammable matter must meet the values stated below.
The Base
The base must, of course, be firm and have adequate load-bearing capacity.
This will usually pose no problem when assembling in an open fireplace.
In case of an inflammable floor, the height of the foundation for the insert must
be minimum 300mm.

Distance to inflammable material
When the fireplace insert is mounted in an existing brick fireplace, the
requirements for distance to inflammable material and fireproofing on the floor
will usually be in order.
If it is a matter of a new building, reference is made to any local regulations on
fireproofing etc. You may contact your chimney sweeper for clarification of
any issues of doubt.
350
250
300
For H570, the above distances to inflammable material shall apply, as
measured from the cabinet.
For H470, the distance behind the fireplace insert is 350mm. The distances
to the side and below are the same.
For furniture, a distance of 1.1 metres is recommended.
Distance to non-inflammable material
For non-inflammable material, no requirements apply.
The Chimney
A good chimney draught is essential for how well a fireplace insert will burn.
Note that there should be access to cleaning doors.
The working height of the chimney should typically range between 3.5 and 4.5
metres. Working height shall be understood as the distance from the fireplace
insert top to the top of the chimney.

The internal diameter of the chimney shall be min. 150 mm (inside dim.) in
steel chimneys and min.175-180 mm in brick chimneys or chimneys made of
ceramic units as their inside surface will frequently be rough and will offer
resistance.
All joints and connecting points shall, of course, be tight, and the chimney shall
provide a draught of min. 1.2 mm water head (12 Pa).
Register
If your chimney has a register, this should have a forced opening of min. 20
cm2.
Assembly of Smoke Turn Plate
The illustration below shows how to place the smoke turn plate when viewing a
section in the fireplace insert from the side.
The smoke turn plate is removed by lifting at one side after which it will come
clear of the other side and be taken down into the combustion chamber and out
through the door. Similarly, it is put in place by moving it up askew at one side
and then at the other side, and it is then put in place in the middle.
Combustion Air Supply
A good and clean combustion will benefit from an adequate supply of air to the
fire. To allow for this, it is, however, a condition that air be supplied to the
room in which the fireplace insert has been put up.

In certainly the majority of rooms there will be an adequate amount of air,
particularly if some of the doors between the rooms of the house are left open.
In special cases, an air valve may have to be placed in the exterior wall of the
room in which the fireplace insert has been put up. The air valves are to be
placed so that they may not be blocked.
Floor
On the floor in front of your fireplace insert, there should be a non-inflammable
plate, for instance made of steel or stone material. This plate should be big
enough to reach min. 30 cm in front of the fireplace insert and 15 cm at each
side of the fireplace opening.
Chimney Sweeper
Once your new fireplace insert has been assembled, do make a point of
registering the installation with the chimney sweeper. For one thing, the
installation is to be inspected, and the chimney will also have to be swept by the
chimney sweeper in the years to come.
Using your fireplace insert
Below, you will find a description of kindling and firing of your fireplace
insert. The wood volume and register setting may be varied as required
individually for heating and the draught of the actual chimney.
The inserts are intended for intermittent combustion.
Kindling and Current Firing
1. Put appr. 2kg kindling pins in at the bottom of the fireplace insert, stacked
cross-wise like a log house. Put 2 spirit blocks in the middle, and light these.
2. Close the door ajar, leaving an opening of appr. 2 cm. Open the air damper
entirely under the damper (pulling it all the way out). Leave the fireplace
insert like this for about 5- or 10 minutes before closing the door entirely and
pushing the handle in locked position.
3. Dampen the air damper as required during the kindling.
4. Once the fire has burned down to the state of glowing (no more flames seen),
open the door carefully so that the ashes will no be stirred up and come out.

Cautiously spread the glows using a poker so as to make these lie in an even
layer.
5. Put 2-4 pieces of wood into the fireplace insert, a total of about 1.5 – 2.5 kg.
Put these pieces at the bottom of the fireplace insert, parallel with the
fireplace insert front; one or two pieces may be put on top. The pieces to be
laid at some little distance between them to allow for some air in between.
The front piece will be lit best if it has a chopped side facing the door, and
another facing the glows. Close the door tightly at once.
6. The damper may be opened entirely and damped again once the fire has
caught on well. Just how much the damper should be opened may vary with
the draught of the particular chimney but the flames are now to stabilize so as
to assume the appearance of a “calmly” burning fire.
7. When the wood has burned down to the state of glows (after about one hour),
start all over from item 4.
Ashes
The ashes may be dumped in the waste bin for scavenging. The ashes should
always have been cooled for one or two days before being dumped in the waste
bin as there might otherwise still be glows which might set fire to waste or
waste bag.

Sound Advice
Kindling after some lengthy pause
If the insert has not been used for a protracted period, it should be checked
whether the smoke ducts are intact, and whether there might be blockings in the
chimney prior to kindling.
Chimney Fire
In the event of chimney fire, it is recommended to close the door and the
damper, and possibly call the fire brigade.
Cleaning of Fireplace Insert
All Lotus fireplace inserts have been factory surface treated using original
Senotherm lacquer in colours ”coke” or ”grey”. This treatment will make the
fireplace insert exude a special smell during the initial kindlings but this will
vanish after a few times. Provide good airing. Maintain the surface by brushing
it, using a soft, long-haired auto brush. A cloth with water or other matter may
not be used.
Maintenance of Fireplace Insert
It is recommended that the maintenance of your stove be performed by a
qualified service engineer, and that only spares recommended by the
manufacturer be used.
Packings may look neat but they will collapse in the heat and will thus lose
their ability to keep the fireplace insert tight. Packings should be replaced as
required since good combustion and a clean pane will very much depend on the
fireplace insert being tight.
Skamol broken or Worn may easily be replaced as these have been mounted
loosely, the plates are made of vermiculite this is an insulating material, and the
material is lighter porous. To avoid breaking the plates, it is important that
wood is not thrown, but rather added into the middle of the firebox. Should
you get to crack a skamolplate, it has no significance for insulation.

The smoke turn plate may be worn. It is readily replaced and is fitted as
described above.
Painting of the fireplace insert using Senotherm spray may cover spots or small
scratches. Major damage to be abraded using fine steel wool, vacuum cleaned,
and then sprayed. The tin to be shaken vigorously, spraying at a distance of 15-
20cm. It is imperative that your fireplace insert be out of operation and quite
cold before the spray is used, otherwise you might cause severe damage on
account of fire risk.
Kindling Wood
Kindling wood is the designation for finely chopped small wood pins, 20 – 30
cm long and having a diameter of 2-3cm.
Wood
Birch, beech, oak, ash, elm, conifers as well as fruit trees are all suitable for
wood chopping.
Pressure-creosoted wood, chipboards, coloured leaflets or calendered paper are,
however, not suitable in a fireplace insert. They will develop hydrochloric acid
or heavy metals much to the detriment of the fireplace insert and to the
environment.
Firewood for your Lotus fireplace insert should have a diameter of 7-9cm. The
essence of good combustion is that the wood should be appropriately dry (at a
humidity of 15-20%). If your firewood is too wet, making it burn will prove
hard, there will be no chimney draught, it will smoke a lot, and it will provide a
lower degree of utilization as the water will have to evaporate first. Further, this
may cause damage to your fireplace insert and chimney by way of shining soot
and tar encrustation. At worst, this may cause a chimney fire. If your firewood
is far too dry, it will burn too quickly. Frequently, the gases in the wood will be
released at a rate quicker than they will burn, and part of these will, in unburned
condition, pass up through the chimney. This will also cause a lower degree of
utilization and will harm the environment.
So it is a matter of a balance which you will, with a little exercise, find
reasonably easy to find. Reference is also made to Keeping below.

Keeping of Wood
Your best keeping of your wood will be under a roof, still with good airing, like
in a carport or under a shed roof. Putting your wood on a wooden pallet or the
like, so as to keep it clear of the ground, would be a good idea. Fresh wood
which has been sawn and chopped should preferably be left in this way for one
or two years, depending on the type of wood.
What is available in your fireplace insert?
In your fireplace insert, you will find the present assembly and user
instructions, as well as a glove which will come in handy for firing.
Warning
-The door should always be kept closed at normal operation, and may be
opened for kindling and firing only.
-At normal use, the surface will run hot, and due care should be taken
-Any unauthorized change of the insert will render the warranty nil and void
Operating Trouble
If you have any problems with your Lotus fireplace insert, you may find the
cause below. If not, you will always be welcome to contact your Lotus
distributor.
Your fireplace insert is hard to control – it burns too quickly
If your fireplace insert is new, check that you have followed our instructions.
If your fireplace insert is more than one year old, or if it has been used
extensively, the packings may have to be replaced as the heat may cause the
packings to lose their ability to keep your fireplace insert tight.

Poor fireplace insert draught after the installation
Check that the assembly instructions have been followed. In particular, the
conditions round the chimney may cause trouble. Are the diameter and the
height OK, is it tight, and are flues and transitions tight? A chimney sweeper
may have to be contacted to remedy the problem as the chimney may be
blocked.
Smelling of smoke and soot
This may be due to wind down draught in the chimney and would generally
occur in particular wind directions. The chimney may be too short in relation to
the roof ridge, or trees may have grown up, generating turbulence.
Making your fireplace insert burn proves hard, or the fire may go out
This may be due to a number of causes. Those most typical are:
The damper is not open enough.
The firewood is too wet.
The draught in the chimney is too small; it may have been blocked or is untight.
The layer of glows was too small/had glown out and did not produce sufficient
heat to kindle the pieces of wood. A little primary air may be supplied by
opening the door ajar.
Depending on the particular kind of trouble, you may have to contact your
Lotus distributor or a chimney sweeper.
