If addtitive fuel of timber is combusted, take off these grates from the boiler.
2.5.4 Change of Opening Direction of Stocking Door 1. Raise the upper part of cover (13). 2. Disassemble the stocking door (1) by taking 2 pcs of door pins off (7). 3. Remove 2 pcs of M10 x 55 screws (4) including 2 pcs of M10 nuts (5) and 2 pcs of 10,5 washers (6) into the head metals on the left side.
2.5.6 Filling the heating system with water The water hardness must correspond to ČSN 07 7401 and it is inevitable to treat the water according to Chap. no. 2.2. in case the water hardness is unsatisfactory. The heating systems with an open expansion tank allow the direct contact between the heating water and the atmosphere.

Fig. №. 13 Stocking Door Rosette for Primary Air Supply The rosette in the boiler back part stays closed. If smoke comes out the chimney, the rosette may be opened a little bit. By that more tertiary air is admitted into the boiler. The suffocating throttle of ash pan door controls inlet of secondary combustion air under the boiler grate.
Equipment for surplus heat withdrawal The two way safety vent DBV 1 - 02 serves for surplus heat removal in case the water temperature in boiler exceeds 95 °C. In case the system is equipped with a two way safety vent and the boiler becomes overheated (the output temperature exceeds 95 °C) the two way safety vent creates a cold water circuit which is kept until the temperature drops below the limit temperature.

▶ Follow the instructions for operating the boiler. ▶ When operating the boiler follow the recommended operating temperature. ▶ Operate the boiler with an approved fuel. primary air secondary air III. tertiary air open–Lighting fire/Stocking closed - Operation III. III. Fig.
Fig. №. 19 Scheme of flue gas passage through the boiler Operation 1. After having achieved the heating water temperature regulate the combustion air inlet. Power control is executed by the suffocating throttle that regulates secondary air inlet under the grate by means of the damper or by the adjusting screw of the suffocating throttle itself.
Boiler cleaning - maintenance 1. Ash from ash pan and small ash pan has to be removed in the boiler operation even several times a day according to the type of used fuel, because full ash pan protects the correct division of the combustion air under fuel and evokes rough burning of fuel on grate.
