INSTRUCTIONS FOR USE: Original Chill ™ hot tubs
Cold water and warm air (temperature difference/air humidity) often cause condensed water in the
ash collector. Therefore, the stove is not leaking although there is some water in the furnace. You
can suspect a leakage only if the water level is going down.
Use only small, dry firewood in the stove. The use of larger and damp firewood may double the
heating time and it will also generate a lot of smoke. We do not recommend black alder because it is
sootier than other wood. It is advisable to adjust the air intake of the stove according to the type
and size of the wood, so as to reduce the amount of smoke.
Empty ashes from the stove after each use.
During heating, the tub should be covered in order to limit heat evaporation as much as possible.
The water temperature should be measured every 20 minutes during heating. Because water
stratifies into layers when it warms up, it should be mixed with a Kirami paddle, for example. When
the temperature reaches approx. 32°C, it is advisable to reduce the amount of firewood added so as
to avoid overheating the tub. When the desired temperature has been reached, you may keep a
small fire under the tub where necessary to sustain the temperature. Practice makes perfect in this
as in anything else.
It is advisable to open the cover about 5 minutes before getting in the bath to allow the water to
settle. For reasons of safety and heat evaporation, the cover should be closed as soon as possible
after taking a bath, especially if you intend to use the tub the next day.
Heater paint surface can be stained by drinking classes, pool chemical cans, chemical dispensers
and sometimes even by water with calcium. So please do not use your heater as a table.
MAINTENANCE AND SAFETY OF THE TUB
Surface treatment
Stained spruce
Stained spruce panels will maintain their colour quite well, but they can be re-treated if necessary.
Water-based wood oil Teknoshield 4015 was used at the factory. The tone is Kirami CoalBlack
(Ebenholz, TM-1708). The surface can be treated with similar oil when necessary. Woodex Aqua
suits for treatment in Finland. On top of Teknoshield 4015 you can use different kinds of wood oils
and transparent paints (solvent and water based).
Other remarks
Note that the discharge tap should always be left open in an empty tub. If water gets inside the
tank from somewhere when the discharge tap is closed, water can freeze in the pipes and break
parts.
The external stove is emptied at the same time when you empty the water from the tub. Do not
leave water unsupervised/unheated at subzero temperatures. The plastic drain pipes and taps
freeze really easily. In case the exhaust hose/tap has frozen, the tub can be emptied by removing
the stove to lead the water away from the lower hose. In case the stove is frozen, do not light a fire
but rather thaw the stove slowly.
Note! When emptying the tub you shall leave the cover slightly open, so that no vacuum forms in
the tub.
