Page: 30 / 69

2.3. Stove base

The stove must be installed horizontally, on a stable and unmoveable non-flammable or fireproofed base. For this,
you may either use Kastor’s separately sold protective stove base (picture 7) The stove must not be installed
without fireproofed base of the flammable floor

The stove can be installed directly on the concrete floor, where the concrete slab has a thickness of least 60mm.

Make sure that the stove less than whish to join the casting no electrical cabels or water pipes.
The front corners of the stove are equipped with adjustment screws, with which it can be straightened horizontally
on an inclined. The adjustable legs are delivered in the equipment bag in the stove’s fire compartment. Screw
them into place and adjust as needed.
We do not recommend installing the stove directly on a tiled floor, as its moisture sealing, tile glue etc. may contain
components that are not heat resistant.

Fireproofing of the floor on flammable material:
  400 mm in front of the stove

(protective plate on the floor)

  On the heater sides 50mm
  At the heater back 50mm
  (Or, at the sides and back up to a fireproofed wall; picture 2.2.).

NOTE! Always check floor load capacity. Check the heater weight, stones included, from table 2.

2.3.2. Installation on tiled and waterproof floor

We do not recommend installing the stove directly a tiled floor, as its moisture sealing, the glute ect. may contain
components that are not heat resistant.
The Kastor protective stove base is sufficient, a separate fronting plate is not necessary. (picture 7)

2.4. Safety distances and protections

2.4.1. Safety distances

For stone walls

, the safety distances are 50 mm from the stove’s outer surfaces, preferably 100 mm to achieve

sufficient air circulation. This means the stove will fit a niche of stove width + 200mm (i.e. for the KARHU 20 that is
490 mm + 200mm = 690mm).

The safety distance to any flammable materials is 4

00mm from the stove’s outer surfaces. In front of the stove,

due to heat radiation and the working and maintenance space needed, 1000 mm is a reasonable distance, but
500 mm is sufficient to ensure safety, if the panel in front of it does not heat up beyond 85

C during the burn-in.

Safety distance upwards, ( table 1), measured from stone surface. A protective plate with a 30mm air slot must be
placed on the ceiling if the measurements are not sufficient.

If the flue pipe starts off from the top of the stove with a no insulated connection pipe, the required safety distance
is 400 mm in all directions and 400 mm above.
Take into account the safety distance of stove.

The safety distance between a fitted water tank and the nearest flammable material is    150 mm.

2.4.2. Reduction of safety distances

Kastor protective walls and a stand are available. (picture 7)( 2.3). The chimney's isolated part must reach the protective wall.
Other protection is not needed.

If the sauna has a flammable floor in front of the stove, the area to be protected extends 100 mm 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. If it stands with its back and both sides next to brick wall, 100 mm should be left
on both sides to ensure air circulation. At the back, 50 mm remains sufficient.

The pipe’s insulated part within the sauna must always extend to 400 mm below the ceiling.

For chimneys, the minimum safety distances to flammable material differs from product to product. Always check
the manuf

acturer’s instructions. In case of doubt, approach your local fire safety officials.
