SAFETY DISTANCES
Before installing the sauna stove ensure the required safety distances to inflammable
material are met. The safety distances of the sauna stove are 400 mm to the sides,
250 mm to the rear and 1200 mm upwards. At the base, a concrete board of at least
70 mm must be used.
The Narvi Stony sauna stove must not be installed on top
of an underfloor heating.
If you are unsure please contact your local fire authority
for guidance.
Inflammable construction parts, such as wooden
walls, sauna seats etc.
1. Distance from the vertical surfaces of the sauna
stove to unprotected wooden parts 400 mm to the
sides, 250 mm to the rear and 1000 mm in front.
(Fig. 1)
The protection must also be clear of the floor
and the ceiling.
2. The safety distance mentioned in paragraph
1 can, however, be reduced by half when “light-
single” protection is used. Single-light protection
of this type can be made of a non-combustible,
fibre-reinforced cement board of at least 7 mm
dick or of a metal plate of at least 1 mm which
has been fastened securely enough to the wall.
A ventilation gap of at least 30 mm must be left
between the wooden surface to be protected and
the safety plate by using piping collars. (Fig. 2)
3. The safety distance in paragraph 2 can
be further reduced to 100 mm when double
protection is used.
Double protection can be made of two plates as
described in paragraph 2 and, then a ventilation
gap of at least 30 mm must be left between the
wall and the plates. (Fig. 3)
