INSTALLATION AND OPERATING MANUAL OF STOVEMAN SAUNA STOVE The STOVEMAN sauna stove is intended for providing dry or humid heat in a sauna. Our product range includes various modifications of the Stoveman sauna stoves. The selection has round and angular-shaped stoves. The stove can have a hot water boiler, a glass door and a wall penetration for fire chamber. An appendix to this manual includes a copy of the type approval for CE marking of the sauna stove and the data of the sauna stove model. Commissioning Read this manual carefully before commissioning the sauna stove! The first heating must be performed outside or in a well-ventilated hot room, because the final curing of the external heat-resistant paint of the sauna stoves is completed only after heating and the curing process may give off an unpleasant burning smell. Avoid scratching the sauna stove before that. It s not recommended to fill the sauna stove with stones before the first heating. The stones of the sauna stove must be large granite fieldstones or also sauna stove stones sold in specialised stores. Installation Installation of the sauna stove must follow all local standards and regulations, including those related to national and European Union standards applicable to installation, incl. EN 15821:2010. The sauna stove must be installed onto a base made of non-flammable material and having sufficient load-bearing capacity. The installation of the sauna stove must follow all safety requirements and required distances from other materials as stated on the CE marking. The CE marking is attached to the sauna stove at the lower edge of the mesh, at the right side when looking at the fire chamber s door. If the stove is installed into a recess made of non-flammable material (stone, concrete), then the distance between the wall and the stove must be at least 100 mm, to allow for proper air movement. Due to major temperature fluctuations, the sauna stove stones may crumble over time and lose their necessary properties. Due to this it is recommended to empty the sauna stove from old stones once a year and to replace them with fresh stones. Safety requirements (General fire safety requirements) General fire safety requirements valid in the country must be respected. Minimum required safe distances to flammable materials: At sides and behind the stove 500 mm In front of the stove 1,000 mm From top of the stove to the ceiling 1,200 mm If heat insulation is used, then the required safety distances may be reduced to half; with double heat insulation, the safety distances may be reduced to a quarter. If any wooden walls (panels, boards, timbers) are closer to the stove than the minimum required safety distance, then those wall surfaces must be protected with thermal insulation (for example with a Termoluja board). In that case, the minimum required distance between the thermal insulation and the sauna stove is 250 mm. 1
If the sauna stove is installed onto a floor made of wood or other flammable material, then a concrete base must be cast, with the thickness of at least 60 mm and with dimensions exceeding those of the stove by 300 mm on sides and 400 mm in front. The wall penetration for fire chamber of the sauna stove must be made through inflammable wall (stone, concrete, etc.). It is also recommended to use additional thermal insulation made of mineral wool, etc. (see the figure). There must be no electrical equipment or cables within the safety zone of the sauna stove. NB! A mechanical ventilation system operating by air extraction may cause air exchange problems in the room and insufficiency of combustion air for the fire chamber; thus, such a ventilation system may only be designed and built under responsibility of a specialist with the relevant license. Connecting the sauna stove to the smoke flue As a rule, the Stoveman sauna stoves have the flue gas outlet opening on top of the sauna stove. Special metal flue pipes must be used for connecting the sauna stove to the smoke flue; the flue pipe connections must be sealed with heat-resistant sealing cord if necessary. Any bends in the connection pipes must be round and wide, in order to ensure minimum obstructions of the chimney draught. The flue pipe must enter through the chimney wall and it must be sealed with mineral wool. The connection of the sauna stove to the smoke flue must be made by a specialist of the relevant field. The sauna stove must not be connected to a shared smoke flue. The sauna stove must not be modified without the manufacturer s consent. Heating the sauna stove NB! The sauna stove must be fired with wood logs only. Avoid overheating the sauna stove; this would be indicated by the sauna stove s shell starting to glow red. Overheating deforms the metal and the manufacturer will not bear any liability for defects of the stove resulting from that. The initial heating of a new sauna stove is recommended to do with half the stove-load of firewood and without the stones; the room must be ventilated afterwards. During the initial heating, the final curing of the heat-resistant paint takes place and it may be accompanied by an unpleasant smell in the room. To stop the burning process of an overheated sauna stove, the ash drawer must be closed completely and the fire chamber s door must also be kept closed; if possible, air influx to the room must be shut off as well. It is recommended to pick the first stove-load of firewood (the ignition load) from smaller and easily-igniting pieces of wood, thus having more air and less weight than the standard stoveload. The flow of combustion air is regulated by changing the position of the ash drawer. For igniting the stove, the recommended position of the ash drawer is open by up to 10 mm. When the wood has started to burn, the ash drawer must be placed so that the distance between the ash drawer s front and the fire chamber s wall is 2 3 mm, depending on the actual draught. It is recommended to have a set of handy stove accessories (shovel, brush, stove iron) in the lower-temperature part of the hot room (up to 40 C) for cleaning the fire chamber and for safe operation of the sauna stove. As a rule, the fire chamber door must be kept close during heating. The door can be opened only for the time of adding firewood. With sauna stoves having a glass door, avoid getting water on the hot glass. The hardened glass of the door is not covered by the product warranty. The time needed for heating up the hot room depends on the heat conductivity of the wall materials, the volume of the room and the heating capacity of the sauna stove. 2
The ash drawer of the sauna stove must be cleaned before each heating, because the draught is regulated by way of adjusting the ash drawer s position. If the sauna has not been used for a long time, then the internal flue channels, the fire grid and the ash drawer must be inspected and if necessary then cleaned, and the chimney and the smoke flue must be inspected and if necessary then cleaned by a specialist before starting to heat the sauna stove. The heating surfaces of the fire chamber must be cleaned regularly, i.e. at least after every 20 heatings of the sauna stove. The chimney and the smoke flue must be leaned at least once a year. The cleaning of the sauna stove must follow all local standards and regulations prescribing fire safety requirements for cleaning of heating equipment. It is recommended to keep the grilles of the ventilation openings clean and to clean the ventilation channels at least once per year. The exterior of the sauna stove becomes hot during heating; contact with unprotected skin may cause burns. Always use the delivered safety cloth for grabbing the handle of the fire chamber door when heating the stove. Never throw salt water onto the sauna stove! It is not recommended to throw water with high hardness grade or excessive iron content onto the sauna stove. Product warranty The sauna stoves have a manufacturer s warranty of 24 months after the date of purchase, proven by a purchase slip. 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: Metal deformations; Effects on surface covering; Effects on door glass. Reclamations due to defects must be sent via e-mail to the address of kontakt@evt.ee or as paper mail to the address of AS Eesti Vanglatööstus, Kalmistu tee 22, Tallinn 11216, Estonia. The reclamation must describe the defect and must state the serial number of the sauna stove. The serial number is marked on the sauna stove, at the lower edge of the mesh, at the right side when looking at 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 were the defect is apparent, and by copies of the purchase documents of the sauna stove.
