Protecting the walls
If necessary, the safety distances behind and on the sides of the sauna stove can be reduced with
optional Parra stove protective walls. This allows for reducing the safety distance to 100 mm on the
sides and behind the stove. The distance from the building wall and from the exterior surface of the
stove to the protective wall must be at least 30 mm to allow for air circulation.
When using protective walls, the uninsulated connection duct to the flue must be protected with a
Parra thermal radiation shield. With the thermal radiation shield, the safety distance of the uninsu-
lated connection duct to the wall is reduced to 150 mm. (pls. see figure 4)
Alternatively, the Parra Q20 stove can also be used with the optional single layer protective mantle,
that can be installed on the stove, with which the protective distance to the side and back is at least
150 mm measured from the surface of the stove (i.e. 120 mm from the surface of the protective
mantle), pls. see figure 5.
Protecting the floor
The sauna stove can be installed directly on a concrete floor with at least 60 mm concreting, if the
floor structures under the stove do not have parts susceptible to heat, such as electric wiring or
pipes.
Harmful heating of the structural part underneath the sauna stove must be prevented. The mortar,
glue and water insulation of a tile floor do not withstand the thermal radiation from the stove without
a shield. It is recommended to use the optional Parra sauna stove’s shield platform for protecting
the underlying structures. Use the sauna stove’s adjustable legs even with the shield platform. The
adjustable legs lift the stove, improving air circulation underneath it, which makes the shield plat-
form and the sauna faster to dry after the sauna bath. Carefully observe the instructions from local
fire authorities. If necessary, consult them for advice.
When installing on flammable floor, a Parra sauna stove’s shield platform or corresponding protec-
tive shield must be used. The floor area to shield in front of the stove must extend at least 100 mm
from the sides of the door and at least 400 mm in front of it. Shield this area, if necessary, with a
shield plate of 450 x 280 x 6 mm (optional), which attaches firmly to the floor and the stove plat-
form.
Stove stones
The recommended stones for the stove are peridotite or olivine diabase stones with a diameter of
8–15 cm. The stones must be washed before use. Lay in the stones so that you put the largest
ones at the bottom with the greatest stone surface against the stove’s steel surface. Put the stones
in the side pockets and generously, approximately 10–15 cm, over the centre channel. An appro-
priate amount of stones guarantees a good sauna bath. When laying in the stones, make sure that
the sweeping hole doors stay in place.
