PREHEATING
Before use and arranging the stones, the sauna stove must be heated to remove
the protective agents. 1-2 fireboxes of wood are sufficient for preheating. During
preheating, ensure that there is plenty of ventilation in the sauna to allow the
combustion gases from protective agents to escape. Preheating can also be done
outdoors.
SAUNA STOVE STONES
We recommend that you use NARVI olive dolerite stones. Do not heap stones too
tightly because air must circulate between the stones. NARVI sauna stove stones
have been prewashed and can be placed directly on the sauna stove. Fresh water
must be used as steam water. Seawater considerably shortens the service life of your
sauna stove.
FIREWOOD
Both hardwood and softwood can be used in the NARVI sauna stove. Fell and cut
trees into firewood outside of the growing season. Dry the firewood outdoors in
summer and move it to a dry store before autumn rain. Store one or two years supply
of firewood in surroundings where the moisture is < 20 %.
HEATING
Before heating the sauna stove, the grate must always be cleaned and the ash pan
must be emptied. Start by lightning a small quantity of wood on the upper surface of
the wood. When the wood is burning properly add more wood to 2/3 of the height of
the firebox. To burn properly wood needs air. Use the draught regulator to adjust the
amount of air. Avoid heating the sauna stove so that the channels of the stone basket
glow red for a long time because this will overload the firebox and the service life of
the sauna stove will be reduced! After your sauna leave a little fire in the sauna stove
to dry the sauna..
MAINTENANCE OF THE SAUNA STOVE
Sweep the sauna stove through the soot hatches at least once a year to maintain a
proper draught. At the same time, check the condition of the sauna stove stones and
replace any warm-out stones.
CHIMNEY
- Each heater includes reducer 122/115 mm
- Chimneys: additional equipment if necessary
Always use NARVI chimneys or NARVI chimney flues. When installing the stove
ensure that it stands firmly on its base and installed so that the safety distances are
correct according to the instructions.
Floor protection in front of the sauna stove: Floors made of inflammable material must
be protected with a metal plate extending at least 100 mm on either sides of the sauna
stove trap-door and 400 mm in front of it.
