• Floor material and weight capacity (inflammable, incombustible, tiled and waterproof)
• Note that IKI stoves have a lot of stones and are heavy
• IKI wood burning stoves are recommended to be installed primarily either in a brick chimney, ceramic chimney or an air-cooled chimney. The outer diameter of the stove’s smoke pipe is 115 mm.

Installation of the stove

2.1 Mini-IKI and Original IKI

1. Check that all parts belonging to the stove are included in the delivery.

2. Set the furnace on a solid and fireproof base on two footings in the middle of the installation place of the stove.

3. Remove the white protective plastic from the mesh frame.

4. Set the mesh frame around the stove furnace.

5. Remove the wing nuts on the back of the net and fasten the nails of the net sheath together. Put the wing nuts in place and tighten them.

6. Attach the hinge to the furnace (A.)
   Install the fireplate that prevents the cinders falling to the floor (B.)

7. Install the hatch to the hinge.

8. Check that the distance between the frame and the front part of the coil is approximately 5-7 cm, to have space for the stones. Make sure that the furnace stands horizontally. When the hatch is open, it must lean back so that it will not fall down by itself.

2.2 Setting the stones into stove:
Stones smaller than 10 cm in diameter are recommended. Ordinary stones with a rough finished surface are suitable for a stove. For example, peridotite, olivine-dolerite stones. The stones should not be placed too tightly together, allowing for free air flow between the stones. Even natural stones can be loaded in the outer edges where the stones are not in touch with the heating surfaces.
Fill the space between the mesh frame and the furnace with stones carefully, one stone at a time. The first 20-30 cm from the floor are the most crucial ones while setting the stones into the stove. Then the mesh takes its final round form. The mesh and the furnace intermediate space must be stoned as accurately as possible so that the stones will cover the furnace.
If the stove is for professional usage (public bath etc.), IKI recommends KERKES-ceramic sauna stones ( www.kerkes.fi ) on the surfaces that touch directly the heart of the stove.
NOTE: Stones will descent from time when heated regularly. Stones change interval depends on the quality of the stone and the stove utilization. Check the condition of the stones in normal operation each year, if necessary, remove the broken stones and replace them with new ones.

2.3 Plus part installation instructions
As the stove consists of a separate furnace and fire tube and two separate frames, the installation is done in phases as follows:

1. Assemble the lower part of the stove as in Mini-IKI, Original-IKI and Maxi-IKI, instructions without setting the stones yet to the top part.
2. Adjust the connection smokepipe and the upper mesh in the connection point of the chimney (picture 1.). If the connection point is deviant from the standard connection point of an IKI stove, use a suitable sidecutter to shorten/adjust the tube and mesh.
3. Pile the stones to the lower part of the stove. The mesh should lie against the circular firetube. The piling of stones in the space between the upper mesh frame and the smokepipe is done one stone at a time. When loading the stones try to cover the smokepipe as well as possible. The mesh frame settles in its place when approximately 10 cm of stones have been loaded from the surface of the furnace. It is recommended that two people do the loading of the stones of the upper mesh(pictures 2. and 3.).

2.4 Modifying a chimney connection to a non-standard height
The chimney connection of the plus model can be made even lower in i.e. the following

• Cut smokepipe to a desired height with i.e. with a sidecutter
• Cut the upper mesh from below and cut the straight smokepipe in proportion to match the smokepipe accordingly. Leave the “cut part” of the upper mesh to lean against the lower part of the stove

Safety distances to flammable structures

Please note that the gap between the furnace and the stone mesh must be loaded carefully with stones.

• A. From a smoke pipe without stones to the side 500 mm
• B. From the stone mesh full of stones to the side 100 mm
• From the solid hatch to the front 500 mm (Tip! Leave 1000 mm to have service space)
• C. From the neck of the furnace to the side 250 mm
• D. From the smoke pipe loaded with stones and equipped with a mesh to the side 250 mm
• From the smoke pipe loaded with stones and equipped with a mesh upward 500 mm
• From a smoke pipe without stones upward 1000 mm

3.1 Reducing the safety distances

• 50 % when using simple protection (i.e. 1mm metal/fiber board and a 30mm cavity)
• 75 % when using double protection (double protection board and a cavity)

ATTN! The Plus part version of the smokepipe loaded with stones reduces the safety distances 50 % compared to plain smokepipe without stones.
3.2 Protective base for the stove
IKI stoves also have a “IKI protective base” for the stove (IKI accessories). If that is used the stove can also be installed to the floor with flammable surface. A protective base for the stove also reduces the thermal radiation that a tiled and waterproof floor is possibly exposed to.

Connection heights with 90-degree smoke pipe

The connection height of the stoves is given from the floor to the center of the chimney when stove furnace is installed on its stone legs. ATTN! When using the “IKI protective base” the height of the connection point rises 70 mm accordingly.

Connection heights with 100 cm Plus part

With the 50 cm Plus part, the chimney connection heights are the same as with the 90-degree exhaust pipe alone. The mesh’s of the 50 and 100 cm Plus part have an opening that can be closed with a flange for the outlet pipe. If the flue connection is upwards, e.g. to an IKI T600 stove chimney, the mesh can be stoned from the opening. The chimney connection height of the 100 cm Plus part can be lowered by shortening the mesh at the lower end and shortening the straight exhaust pipe in the same proportion.

Instructions for using the stove

The heating time of an IKI stove is approximately one hour, depending on the size of the sauna room and the stove. The correct bathing temperature for the IKI stoves is approximately 55-70 degrees.

7.1 Initial load and lighting the fire

• Clean the ashes from the furnace and remnants from the previous time you used the stove.
• Open the damper of the chimney, the knob on the stove hatch and ash box under the furnace to get incoming compensation air to maximum amount.
• Set the wood (max. 2/3 of the height of the furnace) lengthwise in the front/middle part of the furnace, the bigger wood under and the smaller wood on top.
• Light the fire on the top of the woodpile, for example with a lighter piece, cardboard packages, birch bark or chopped firewood. Keep the draft in fully open position at that moment.
• There is a knob in the stove hatch that allows you to regulate the draft. The regulation is done by moving the knob to the right (open) and to the left (shut).
• You can also regulate the draft by opening the ash box under the furnace.
• When adding wood to the furnace during heating, pull the ember to the front of the furnace against the fire plate and add 2-3 pieces of chopped wood on top of the ember in front/middle part of the furnace. IKI recommends that the maximum amount of firewood should be 2/3 of the space in the furnace.
• NOTE! The hatch of the stove may change color with time, or the paint may wear out. The hatch can be repair painted using 600 degree heat resistant paint, if needed. Before painting the hatch should be polished and cleaned with a degreasant.

Troubleshooting

1. Check the chimney (block, birds nest), check that the damper is open.
2. Has the chimney been sooted according to the instructions?
3. Are you in a region of low pressure? Burn some paper in the furnace first, keeping the hatch open.
4. Check that the fire lighters are dry.

The draft is too strong| 1. Regulate the draft with the hatch and, if needed
2. If the chimney is high, regulate the damper
The sauna does not heat up correctly| 1. Is the stove correctly measured with regard to the sauna room? (space, level of insulation, are there many log walls or a lot of stone surfaces)
2. Is the ventilation correctly measured?
3. Are there enough stones, have they been loaded correctly?
4. Check the condition and quality of the stones (Olivine-dolerite stones, smaller than 10 cm in diameter)
The stones do not heat up enough| 1. Are there enough stones, have they been loaded correctly?
2. Check the condition and quality of the stones (Olivine-dolerite stones, smaller than 10 cm in diameter)
3. Is the firewood dry and has it been loaded according to the instructions?

The water quality for the stove

Mn < 0,05 mg / l
Ca < 100 mg / l
Chlorinated water| Health hazard| PROHIBITED!
Sea water / salt water| Fast corrosion| PROHIBITED!

Dimensional drawings

The outer diameter of the stove’s smokepipe is 115 mm.
The distance from the center of the smokepipe to the back of the heater rim is in MINI-IKI 130 mm and in Original,Maxi-IKI and Löyly-IKI 150 mm.

Sweeping instructions

1. Start by removing the stones from the stove.
2. Open the hatch in the chimney pipe on the stove (as seen in picture below). This does not require any tools.
3. Sweep the chimney using bendable nylon brush. DO NOT USE metal brush! It might damage the pipe from inside.
4. Other option is to use industrial vacuum cleaner to clean up the spiral.
5. Finally spray or pour some water and/or use the brush to clean up the detachable smoke pipe (not the spiral!)

Ventilation of the sauna and getting compensation air

A wood burning stove needs sufficiently compensation air in order to burn well. A sauna room also requires oxygen-rich breathing air for the sauna bathers. Also, the drying of the sauna room after bathing requires a functional ventilation system. There are several ventilation systems provided by manufacturers, but there is probably no system that would be the only correct one. It is most important to have fire ventilation near the stove and some fresh air for the bathers to breath.
12.1 Tips for ventilation
Fire ventilation can work near the stove from outside, for example through a pipe equipped with a 50-100 mm grate and a disc valve beside the stove on the floor (for example a 50-100 mm pipe 50-100mm above the floor). Fresh bathing air is directed beside the stove for example with a 100 mm pipe 50-100 mm above the stone pocket of the stove.
The flow out of the sauna is preferably between the lower and upper bench through a disc valve equipped with an adjustable grid on the wall. The air valve can also be placed on the ceiling or on the wall up close to the ceiling, opposite the stove. The stove makes the air rotate inside the sauna room and the oxygen-rich compensation air moves upward and heats up in the process.
12.2 Automatic ventilation
In automatic ventilation the air circulation and ventilation is assisted with an IV machine, otherwise the principle is the same as in the natural ventilation.
12.3 Using a chimney ventilator and several furnaces in the same room

• A chimney ventilator is not recommended to be used with the woodburning sauna stoves. The temperatures of the combustion gases may break the ventilator
• If there is more than one furnace in the same room, their combustion gases must be directed to their own exhaust ducts. For example a cauldron and stove require a 2-passage chimney
• The fire ventilation and compensation air inlets must be measured as per situation (capacity for two furnaces, adjustable valve for the amount of air)
