.
.
.
RS series boilers are cast iron sectioned boilers.This brings easy assembling and easy capacity increasing by adding
sections to the boiler. The transportation and installation of the boiler is easy because of the boiler is assembled in boiler
rooms. It is easily to carry or shift position without breaking walls etc.
RS series boilers are produced from special cast iron alloy EN GJL 200 , which gives high resistance against corrosion and
thermal expansions. They are long life boilers according to this special cast iron alloy.
With the help of horizontal and three pass specially designed sections burning gases pass three times in the boiler and
transmits burning energy to the water inside the sections at high level.
RS series boilers are high efficiency boilers. ( According to the fuel max. heating value % 91 –93 ). With this high efficiency
and perfect isolation more energy is gained with less fuel. Heat loses are minimized on RS series boilers.
By appropriate burning room, heat transfer surface, turbulator, collector and isolation high heat transfer and optimum flue
gas emission results are provided.
In RS series boilers,heat transfer surface areas are increased by the special wings in the burning room and chimney
ways.This increases the heat transfer ability of cast iron boiler to the maximum level.
RS series boilers operating pressure is 6 bar maximum, and working temperature is 90 °C maximum.
RS series boilers are, blowing burner, cast iron sectioned, between the capacities 76 –145 kW with proper burner
connection, works with gas or liquid fuel in 5 different ( 5 – 9 sections) type.

** Ventilated airing system is used.
*** Bottom value shows the clean
air input up shows the air output.
Cast Iron Sections with High Efficiency Design :
3draught design forces the flue gas to circulate inside the body of the boiler three times before the chimney exit,
transferring all usefull energy to the water inside the sections. The optimized combustion chamber combined with perfect
heat insulation provides maximum fuel efficiency.
The combustion room of the boiler is positive pressure. Boiler is working under horizontal 3 pass principal.
Boiler Room Ventilation :
There are three reasons for fresh air in boiler rooms.
1.The air needed for the burning in the boiler.
2.The air needed for prevention of dirt and dust,for releasing the gases and fuel to put out.
3.The air needed for overheating in the boiler room.
Ventilation for first two reasons are continously needed.The third one is needed especially for the boilers which
are working on summer time.
Maximum temperature for the boiler room must be 32 °C and boiler room must be protected against freezing.

Plumbing Instructions :
Fresh water must be added periodically to the plumbing. The chalk and other chemicals will connect with the system and
become solid . For avoiding this , closed expansion tank must be used in the system.In the systems that closed expansion
tanks are used, water will flow in closed system so it will not evaporate and lost.So in this kind of systems the water level
wiill stay same and fresh water addition will not be necessary. This will prevent chalk and dust and the life of the sytem will
be long.
The water in the radiator or heating system is not healthy.Do not use this water as drinking or cleaning water.Do not take
water from the system.If the water level is low , water addition is needed.
For avoiding chalk and other chemical dust problems soft water must be used in the system.Plumbing system water quality :
Ph ≥ 7,2 Th ≤ 25 °Fr
If the city sanitary water is not in requested quality water addition from wells or other sources must be made after testing
it.For reaching the requested quality additional processes must be applied to the water if needed.
For avoiding the chalk and other dust to get in to the boiler, or from boiler to plumbing system dust holders must be placed
in and out line of the system.
Circulation pump must be connected to the water output of the boiler and the capacity of the pump must be suitable to the
boiler capacity. If not,problems may occur in flowing of the water and heating efficiency of the boiler.
For working the system properly 4 way mixture valve or thermostatic control by-pass pump must be used for increasing
return water temperature.
By connecting a three way motor valve between the forward and return line of heating system,the water that flows to the
system can be controlled in ratios.
There must be water inside of the boiler every time. If not , corrosion can occur in the boiler and the plumbing system. If the
boiler will not be used in winter season, for avoid freezing , anti-freeze solution must be used.

Operating Instructions :
In the system , the difference between direct flow temperature and the return temperature of the water must not be over 20
°C. The return water temperature must be over 50-55 °C. Boiler protection pump must be used for increasing the return
water temperature. The water level of the system must be measured every day (if it is open system by hydrometer,if it is
closed system by manometer) and water must be added if the level is measured low. But this water addition must not be
made while the system is hot. If there are problems that cause water leakages they must be fixed as soon as possible.
Plumbing system must be made by certificated professionals, under the terms of EN standards. EN approved materials
must be used in the system.
These connections must be made by certified professionals under the terms of EN standards.EN approved materials must
be used in the system.Burner,control panel, ecopanel etc. Manufacturer or distrubutor warnings, instruction manuals must
be read .Burner must not be started before boiler circulation starts.If circulation or protection pump has a failure burner must
be switched off. This system must work coordinate. Turning the pumps on when the water heat reachs over 40 °C is
completely wrong. Circulation pump and burner must work simultaneously.
Protection pump must be chosen properly accoridng to the capacity of the boiler.The connection of the pump to the
collectors must be done correctly with valve and thermostat connection. This way,system may stop in adjusted
temperature.In any failure situation (contactor,thermic failure,electricity cut ,other failures.) when the pumps are not working
( heating and protection pumps etc..) burner must not start. System must do this automatically.Electrical system must be
made according to all above information.
Loading and Unloading the Boiler Water :
Plumbing and all radiator valves must be opened if the boilers water will be unloaded. All the systems water can be
unloaded by boilers drainage as if the boiler is in the bottom of the system.If some part of heating system is under the boiler
room,unloading the water process can be made at a point at the bottom of the system.
Water must be loaded from the tap over the plumbing system to the boiler.During the loading process all valves of the
plumbing system and the radiators must be opened.For preventing air fill to the system this operation must be made slowly
and the stopper in the top must be opened. When water comes from this stopper it means that the process is finished. Air
must be taken from every radiator.
Water must be in quality which mentioned on ''plumbing instructions''.
Boiler must not be filled up with water when it is hot. This can cause cracks in sections.
