USAGE
Warning!
Never start the fire when the tub is empty or the
water level is insufficient! Heating a non full tub
will destroy the heater!
Always check the amount of water in the tub
before lighting the stove!
The tub must always be filled so that the water
level is at least 5 cm above the upper pipe of the
heater (picture on the right). Only then it is safe to
start the fire.
Do not start emptying the tub until the fire in the heater is
completely out! Heating a non full tub will destroy the heater!
The water in the tub must not be allowed to freeze during the
winter. Empty the tub or make sure that the water is heated
adequately. The heater cannot be connected with a circulation
pump! It will not stand the pressure, since it has been designed to
use only gravitational free circulation.
Before using the tub for the first time, we recommend to rinse the stove's water circulation pipes
carefully. Rinse the inside of the heater through upper pipes with water so that possible garbage
comes out of the heater. When filling the tub, make sure that the rubber hoses used for connecting the
stove do not leak. If necessary, tighten the hose clamps.
When using lighter fluid act according to the instructions of the fluid. Never use any other fluids than
those that are made for it. We recommend the use of burning pieces, for example Burner- paraffin
bags.
Do not overheat the water. We recommend a bathing temperature of no more than +37°C.
Empty the heater from ashes after every use. If the grates stay inside the ashes, it will shorten the
lifetime of the grates considerably.
Use only small and dry firewood for the heater. The use of big and moist wood will easily double the
heating time. Use of common alder is not recommended, since it causes more soot and stickier soot
than other firewood.
The use of the heater that is loaded from outside of the barrel is as easy as the use of any other normal
fireplace. We recommend the use of small firewood when starting the fire and then gradually add
bigger ones, if needed.
While heating the water, it is advisable to keep up a fair-sized fire in the heater so
that the wood would burn properly and the maximum output can be achieved.
When keeping a small fire the heating time will be much longer.
Air intakes in the furnace door should be adjusted according to your needs. When
fully open the fire runs well but power might not be optimal. Please find the best
position for your needs.
When hardwood such as oak is used as firewood, the furnace should be fitted
with an acid-steel ash box (sold separately) to protect the bottom of the stove furnace from the acidic
hardwood ash and the corrosion it induces.
