3.2 Heating
Before lighting the fire, make sure that the stove grate is clean,
and the ash tray is empty.
Use dry firewood of a suitable size and make sure the fire is burning properly
in the stove while heating the water. Add more wood in 15–20-minute intervals.
Don’t fill the hearth with too much wood.
Avoid using wet firewood of poor quality since pitch and soot will form in
the chimney. Alder wood also builds up more soot in the chimney than other
types of wood. Never use pressure treated wood or e.g. construction waste
in the stove.
You may use lighter fluid or fire starters to light the fire.
Do not use other flammable liquids when lighting the fire as they might form
gasses and cause an explosion!
Stir the water during heating to achieve an even water temperature and before
measuring the water temperature. Otherwise keep the hot tub lid closed to heat
the water faster and save energy.
When the temperature reaches around 30 degrees Celsius, you can use less
firewood to keep the water from becoming too hot.
Recommended bathing temperature is at around 35–38 degrees Celsius.
The temperature should never exceed 40 degrees Celsius. For small children and
when bathing longer than 10 minutes, lower temperatures are recommended.
The amount of smoke can be reduced by adjusting the air intake in the stove
and by using chopped, dry firewood.
While bathing, check that the ash tray does not fill up with ash all the way up
to the grate as the grate may overheat and be damaged.
3.3 After use
Check that the fire and ember in the stove has gone out completely before
starting to drain the barrel of water. Pull the plug in the stove and hot tub
and drain the water. Check that the water flows where you want it to drain.
Always empty the stove of ashes after use.
Wash the hot tub after use according to the maintenance instructions
(see Maintenance of the hot tub).
Cover the dry and clean hot tub with the lid until the next use.
3.4 Use in winter
Before using the hot tub in winter, always check there is no frozen water in the
barrel, pipes, or stove as this might damage the stove. Never try to melt any ice
in the stove/pipes by lighting a fire in the stove. The stove might melt and be
destroyed if the water does not circulate properly. If there is frozen water in the
stove or pipes, you must not light the stove until you have made sure the water
is circulating. Otherwise the stove might build up pressure which might cause
serious personal injury.
Please note that heating the hot tub in winter takes longer and requires more fi
-
rewood. The insulated lid available as optional equipment makes it faster to heat
the barrel and keeps the water warm longer.
When bathing in winter, use a beanie or some other headgear to avoid getting a
cold.
The lid of the hot tub is not made to withstand great amounts of snow. Sweep
away the snow from the lid on a regular basis.
After use, empty the hot tub, hoses, and stove with extra care to avoid them
freezing, which might cause damage.
