installation and usage manual

Please save these instructions for later use!
Once the installation is done, this manual should be given to the sauna’s owner or the

person in charge of running it.
Please read these instructions prior to installation and first use!

Inspect both product and the contents of the package as soon as you receive them. Report any
transport damages to the deliverer.

1.1. Package contents and its inspection

The stove package contains:

• Stove

• Within the fire compartment

o Installation instructions
o Grate
o Connection pipe
o 2 adjustment legs
o Door handle and attachment screws
o Air guide plate.

1.2. Important matters and regulations

During installation and use these instructions and all relevant official regulations must be
followed. The sauna stove must not be used for any other purposes such as drying clothes,
heavy heating during building etc. The stove must also never be covered in any way during use
or when it is warm.

Also check the following aspects and their influence on your choice of stove installation location:

o Safety distances to flammable and non-flammable structures (Chapter 2.3. and

2.4.)

o Location of chimney connection (height from floor of any existing chimney

connection or installation route of any new chimney pipe)

o Floor material (flammable, non-flammable, tiled and waterproofed)

2. Installation and preparation for use

2.1. Preparing for use and burn-in

• Install door handle according to chapter 2.7.

• Place the stove outdoors on a non-flammable base without stones.

• Remove any decals and protective plastic sheeting.

• Check that the grate and the air guide plate (picture 2) are in place.

• Install the connection pipe delivered with the package into the flue opening on top of the

sauna stove.

• Burn-in: The purpose of the burn-in is to remove out of doors any flammable protective
coating substances and to harden the stove’s coating. Burn a few full loads of wood in the

25 / 51

fire compartment. Continue the burn-in until there are no more fumes rising from the
stove.

• Once the stove has cooled down after the burn-in, move it into the sauna.

• See to it that the sauna is well ventilated during the first couple of heating.

• Side panels can be loosened from the mantle if necessary, they are fastened with bolts at

the top and bottom.

2.2. Stones and their arrangement

Use peridotite or dunite or darkish natural stones with diameters of over 10 cm. always wash the
stones before installing them. They must not be stacked too tight or heaped up – arrange them
so that plenty of air can pass between them to warm the upper stones, as well. The maximum

stone capacity is about Saga 20 150 kg.
Cover the sides of the fire compartment fully with stones so that the safety distance to the side
remains at the minimum.

For the stove’s proper functioning it is essential that the hot air circulates between the stones to
heat them quickly. If the stones are too small or improperly arranged, you will heat the sauna
instead of the stones!

2.3. Stove base

The stove must be installed horizontally, on a stable and unmoveable non-flammable or fireproofed base.

The stove's legs are equipped with adjustment screws, with which it can be straightened
horizontally on an inclined surface. The adjustable legs are in the equipment bag in the stove’s
fire compartment. Screw them into place and adjust as needed.

Fireproofing of the floor on flammable material:
400 mm in front of the stove
250 mm to the sides
250 mm behind the stove
(Or, at the sides and back up to a fireproofed wall; picture 2.3.).

2.3.1. Installation on wooden floor

On a wooden floor we recommend installation on a 60 mm thick, smoothly cast concrete slab,
which rises towards the back, with risers to provide a ventilation slit between it and the floor. The
stove is then straightened by adjusting the legs.

ATTENTION! Always check the carrying capacity of the wooden floor, as the loaded stove weighs more
than 250 kg.

2.3.2. Installation on tiled and waterproof floor

It is not recommended to install the stove directly on a tiled floor because among other things moisture
barriers and plate glues may contain substances vulnerable to warmth. Use for example the above­mentioned concrete slab.

2.4. Safety distances and protections

2.4.1. Safety distances

ATTENTION! Since this is a stove with a flue outlet on the top, the central factor in determining
safety distances is the distance required by the connection pipe and flue channel.
Safety distances for the non-insulated connection pipe are 1000mm in all direction and 1200mm
above it.
This makes the stove's own safety distances irrelevant. See Picture 2.4.1.
These safety distances can be reduced by installing insulation according to chapter 2.4.2.

26 / 51

Safety distances for the insulated flue channel are between 50mm and 150mm with the stove's
safety distances being the essential factors here.

For stone walls, the stove's safety distance is 50mm from the stove's outer surfaces, but
preferably 100mm to ensure sufficient air circulation.

The stove's safety distance to flammable material is 250mm to the side, at the back 500mm from
the stove’s outer surfaces. A safety distance of 1000mm should be left for in front of the stove
due to heat radiation and to allow room for work and maintenance. The absolute minimum is
500mm, but then you must ensure that the nearest panel in front of the stove does not exceed a
temperature of 85oC during test heating.

When the distance from the stove upper surface is at least 1200mm, the ceiling does not require
protection.

2.4.2. Reduction of safety distances

The required safety distances at the back and sides can be reduced by 50% using a single layer
of protection and by 75% with a doubled layer. The protection can be either a 1 mm thick metal
sheet or 7 mm of fibre-reinforced cement board (not gypsum board coated with paper or similar).
(Picture 2.4.1.) Safety distance is measured from the stove to flammable material.

A ventilation space of 30 mm must be left between wall and protector. The protector must be
detached from floor and ceiling (likewise between the plates for doubled protectors). If the sauna
has a flammable floor in front of the stove, the area to be protected extends 250mm beyond the
door’s sides and a minimum of 400 mm in front of it. In this case, the protection must be at least
a 1 mm thick metal sheet.

If the stove is installed with one side and the back against a brick wall, safety distances of 50 mm
to the side and 50 mm at the back are sufficient. Recommendation 100mm to ensure air
circulation.

The safety distances around a non-insulated connection pipe can be reduced in a similar
manner. The flue pipe’s insulated part within the sauna must always extend to 400 mm below the
ceiling.

In the case of the insulated part of the pipe the stove's safety distances are the determining
factor, which means that they can be reduced with insulation according to Picture 2.4.2.

For chimneys, the minimum safety distances to flammable material differs from product to
product. Always check the manufacturer’s instructions. In case of doubt, approach your local fire
safety officials.

2.5. Connecting the stove to a brick chimney

The stove can be connected to a brick chimney from the top and from behind. For a brick
chimney connection, the safety distances and protectors named in chapter 2.4. and the
chimney’s masonry regulations must be adhered to.

2.5.1 Stoves Saga JK and KSIL with extended feed doors

Stoves with extended feed doors must only be installed into walls made of non-flammable
material (brick, concrete etc.).The non-flammable material must be arranged around the door

extension as shown in picture 5. If there is a flammable floor in the room with the door, the area
