24 hours than one load of fi rewood in Stropuva S40 solid fuel boiler burns almost for 48 hours (35-40 hours). Solid fuel boiler Stropuva S10 could be used, but warming up of building would take longer and fuel load would need to be added 2-3 times in 24 hours.
TECHNICAL PASSPORT INSTALLATION AND MAINTENANCE INSTRUCTIONS 2.1 DESCRIPTION OF BOILER STRUCTURE Boiler is cylinder made of steel, enveloped in a cylinder of steel of bigger diameter and this whole construction is thermally insulated. Heated water resides between these two cylinders. At the front part of boiler there is draft regulator (2) (more information in 7.3).
TECHNICAL PASSPORT INSTALLATION AND MAINTENANCE INSTRUCTIONS 3.2 AIR DISTRIBUTOR WITH BURNING CHAMBER STABILIZER (Figure 3) Burning chamber stabilizer is mounted (fi g. 3), on the smallest part of telescopic air supply pipe (7) (fi g. 1), it is integral in new boilers. We also developed units for repairs that consist of two parts.
Put the fi re grate (19) (fi g. 1); (fi g. 4), on the bottom of universal and “BIO” boiler when burning wood. This part is included with “U” and “BIO” solid fuel boilers “Stropuva”. Figure 4 3.5 DEFELCTORS (fi...
TECHNICAL PASSPORT INSTALLATION AND MAINTENANCE INSTRUCTIONS 3.5 FLUE RING (fi gure 6) If there is excessive draft in boiler, use valve (fl ue ring) (fi g. 6) to add additional air from boiler room. Flue ring is on the opening used for boiler smoke removal (5) (fi g. 1). Flue hole must be open in order to reduce draft and vibration.
TECHNICAL PASSPORT INSTALLATION AND MAINTENANCE INSTRUCTIONS 4. TRANSPORTING AND STORAGE Unattached boiler can be transported only in horizontal position. If weather is good, it can be transported in an open vehicle; otherwise it needs to be transported with covered vehicle. If boiler is transported in vertical position, additional safety measures must be used for protecting boiler from overturning and scratching.
TECHNICAL PASSPORT INSTALLATION AND MAINTENANCE INSTRUCTIONS must be cleaned periodically in accordance with mentioned fi refi ghting requirements. We recommend: • Install stainless steel liner inside of chimney; correctly installed liner protects the chimney from condensation and moisture; • Liner should not signifi cantly reduce the diameter of chimney opening; •...
TECHNICAL PASSPORT INSTALLATION AND MAINTENANCE INSTRUCTIONS 6.1 DESCRIPTION OF DIAGRAM OPERATION (fi gure 8) Pump (P) pulls water from heating elements and pushes it through boiler and into heating elements. Through balance tap (bk1) hot water goes to closest radiator which can operate in gravity circulation mode in order to protect the boiler in case of power loss (radiator has no temperature valve).
18. Valve for fi lling up i/i 1/2“ - 1 pcs. For boilers S7, S10, S20, S7 BIO, S20 BIO and S10U, S20U, nodes are assembled from parts D 20. For boilers S40, S40 BIO and S40U node is assembled from parts D25.
14. Circulation pump R – to/out of radiator For boilers S7, S10, S20, S7 BIO, S10 BIO, S20 BIO and S10U, S20U nodes are assembled from parts D 20. For boilers S40, S40 BIO and S40U node is assembled from D25.
13. Ball valve V/i 1“ - 4 pcs. For boilers S7, S10, S20, S7 BIO, S10 BIO, S20 BIO and S10U, S20U, nodes are assembled from parts D20. For boilers S40, S40 BIO and S40U node is assembled from parts D25.

ATTENTION! 7.2 RECOMMENDATIONS FOR FIRING OF UNIVERSAL BOILER ,,STROPUVA” Air valve that lets air fl ow under fi re grate (19) (fi g. 1) is controlled with help of switch valve (6) (fi g. 1) on the top part of boiler on the same side as fl ue. Switch valve (6) (fi g. 1) has: a) handle (bolt for fi...
TECHNICAL PASSPORT INSTALLATION AND MAINTENANCE INSTRUCTIONS 7.3 SETTINGS OF DRAFT REGULATOR (fi gure 13) Operation of this regulator is based on the principle that while housing gets hotter and expands, valve (1) closes and when its housing is getting colder valve opens.
TECHNICAL PASSPORT INSTALLATION AND MAINTENANCE INSTRUCTIONS 7.5 CLEANING AND MAINTENANCE OF BOILER When using fi rewood you must remove the ashes every month. When using peat and coal, ash must be removed before each fi ring. Naturally some resin accumulates on insides of boi- ler, amount of resin increases when fl...
TECHNICAL PASSPORT INSTALLATION AND MAINTENANCE INSTRUCTIONS Consequences Most common mistakes of installation Troubleshooting 1. High fl ow cools the walls of combustion chamber and smoke ope- ning enough for humidity to appear on them. When boiler is heated humidity disappears, but it makes the ash stick to the walls and 1.
TECHNICAL PASSPORT INSTALLATION AND MAINTENANCE INSTRUCTIONS 9.2 DANGERS OF PRESSURE Pressure can get higher: in case of power loss when circulation pump stops working, boiler is not fi lled with cold water from heating system and temperature rises to the critical point, then draft regulator is turned on, it closes the valve at the selected temperature, therefore air is not supplied and boiler is extinguished.
