3.6. Water for generating steam
Please use only clean fresh water for throwing onto the heater. The water must
be of sufficient quality because water containing salt, lime, iron, humus, acidic
compounds can cause the heater to rust prematurely. Seawater, in particular, can
lead to corrosion especially quickly.
N.B. Do not throw seawater onto the heater!
Water suitable for throwing onto the heater has:
• humus content of <12 mg/liter;
• the iron content of <0.2 mg/liter;
• calcium content of <100 mg/liter;
• manganese content of <0.05 mg/liter;.
Throw steam water directly onto heater stones and if possible avoid water
getting onto the metal parts of fire chamber and chimney.
3.7. Maintenance
N.B. The heater must not be modified without the manufacturer’s consent.
Heater
-
The ash drawer of the heater must be cleaned before each heating, because
the draft is regulated by way of adjusting the ash drawer’s position and the air
needed for burning can cool the combustion grate sufficiently, which extends
the service life of the grate.
-
Soot and ash accumulate into the smoke ducts and these have been
periodically removed through the cleaning hatch and fire chamber.
-
Temperature fluctuations cause heater stones to crumble. It is therefore
recommended to rearrange them at least once a year or even more frequently
if the sauna is used very often. You should also remove all stone pieces and
replace cracked stones with new ones.
-
You should clean the heating surfaces of the fire chamber periodically - at
least after every 20 heatings.
Chimney
-
Chimney and connecting pipes should be cleaned regularly, at least once a
year, and certainly whenever the heater is not been in use for a long period of
time (three months and longer).
-
The soot caused by incomplete combustion and accumulating due to non-
regular cleaning can catch fire in the chimney. In case of chimney soot fire
proceed as follows:
1. Close the ash drawer, heater door and damper (if the damper is installed).
2. Call the local rescue service.
3. Do not use water to extinguish the fire.
4. After the soot fire a chimney sweeper has to inspect the heater, the
connection pipes of the heater and chimney flue as well as the chimney.
3.8. Troubleshooting
There is no draft in the smoke flue. Smoke enters the sauna room.
• There are leaks in the smoke flue connections. Find leaking connections
and seal them.
• Brick flue pipe is cold and the natural draft is insufficient. Start the ignition
with a smaller and faster ignition, if possible make the chimney longer.
• There is negative pressure in the room due to an extraction ventilator or
other devices. Ensure adequate air volume for compensation.
• Several fire chambers are used simultaneously. Bring the construction in
compliance with the requirements.
• The ash drawer is full. Empty the ash drawer.
• The smoke ducts of the heater are blocked. Clean the smoke ducts of the heater.
• The flue pipe is installed too deep into the chimney flue. Install the flue pipe
correctly.
Sauna does not heat up.
• The sauna room is too big for the heater’s heating output (section 1.).
• The sauna has uninsulatd wall surface. Have the quality of construction
inspected and bring the construction in compliance with the requirements.
• Firewood is damp or its quality is otherwise low (section 3.3).
• Lack of sufficient draft in the smoke pipe. Have the entire smoke pipe
inspected if it complies with the requirements.
• The smoke ducts of the heater are blocked (section 3.7.).
Heater stones do not heat up
• Heater’s heating output is too big for the sauna room (section 1.).
• Lack of sufficient draft in the smoke pipe. Have the entire smoke pipe
inspected whether it complies with the requirements.
• Firewood is damp or its quality is otherwise low (section 3.3).
• The smoke ducts of the heater are blocked (section 3.7.).
• Check the placement of stones p 3.4.). Remove small stone pieces and
stones with a diameter of less than 10 cm from the stone rack. Replace
weathered stones with new undamaged stones.
The heater emits odors.
• See sections 2.1. and 3.2.
• Onto heater stones substances have been spilled that emit odors when
heated. Clean or replace contaminated stones.
• The hot heater can amplify the odors mixed with air, which, however, are not
caused by the sauna room or heater. Examples: paint, varnish, oil, spices.
Locate and remove the source of the smell.
4. Warranty
The sauna heaters have a manufacturer’s warranty of 24 months after the
date of purchase, proven by a purchase receipt.
The warranty covers defects due to manufacturing errors. The warranty does not
