Throw steam water directly onto heater stones and if possible avoid water getting onto the metal parts of fire chamber and
chimney.

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.

Warranty
The sauna heaters have a manufacturer’s warranty of 24 months (Stoveman Heavy 36 months) after the date of
purchase, proven by a purchase receipt.
The warranty covers defects due to manufacturing errors. The warranty does not cover the following effects caused by the
joint effect of temperature and steaming water to:
•
Metal deformations;
•
Surface covering;
•
Door glass;
Reclamations due to defects must be sent via e-mail to the address
or as paper mail to the address of
AS Eesti Vanglatööstus, Harku tee 59, Tabasalu 76901, Estonia.
The reclamation must describe the defect and must state the serial number of the sauna heater. The serial number is marked
on the sauna heater, at the lower edge of the mesh, at the right side of the fire chamber’s door, and/or on the top plate of the
fire chamber. The reclamation must be accompanied by photographs of the places where the defect can be seen, and by
copies of the purchase documents of the sauna heater.
