Description : In this manual you will find the instructions for Rima three pass cast iron boilers suitable for both gas and liquid fuel. RS series hot water boilers and related informaton for installation,operation and maintenance of the boiler. For high efficiency and proper working conditions please read this manual carefully.
RS series boilers are delivered as sections and services assemble the boilers in the operation area.The assembling of the boiler must be made by Rima technical services . Removing or re - assembling of the boiler should also be made by licensed Rima services, if not the risk of damage is high.
Safety Instructions : Always observe the following safety instructions and regulations. Always perform the following steps prior to inspection work. Close the gas shut-off valve. Close the heating feed and return. Danger! If you smell gas, risk of poisoning and explosion due to a malfunction! If you smell gas : Do not switch lights on or off.
General Characteristics of RS series Boilers : 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. RS series boilers operating pressure is 6 bar maximum, and working temperature is 90 °C maximum.
Boiler sections are delivered as not - assembled according to the boiler room specifications and dimensions.In not assembled deliveries, sections and assembling aparats are delivered on a pallet, cabins,isolation and other elements are delivered in a box. Rima technicians make the assembling of the boiler.
Recommended Minimum Distance for Installation: Do not put flammable materials on top of the boiler or near the boiler than specified safety distance. The measurements of the boiler room and the empty spaces must be arranged properly for future assembling repairing, re- assembling, burner connecting issues.
In Natural Gas or LPG use ; boiler room,flue,system and plumbing issues must be under parameters of EN standarts and gas offices orders. Rima is not responsible for any failure or problems that will be occured because of inadequate or not sufficiently qualified conditions of boiler room, plumbing and other systems.
Cast Iron Sections with High Efficiency Design : 3 draught 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.
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.
For healthy working conditions of the boiler,temperature difference between water forward and water return must not be more than 20 °C.And boiler must not be started or work under the water volumes which is mentioned in the below table. *** RS series boiler is designed,forced circulation hot water heating systems only. Gas Side Resistance and Exit Flue Gas Temperature :...
Important Instructions About Flue : Important Instructions About Connecting the Fuel Tank : The platform of the fuel tank must be strong to carry the tank. If the fuel tank is outside tank , connection pipes must be isolated. Fuel tank must be placed in higher level than the burner.The height difference between the burner and fuel tank ( H ) must be more than 4 m.
Operating Instructions : Heating System : 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.
Water level of the boiler must be controlled. Water must be added to the boiler if the water level is low. Please call Rima technicians if there is a water leakage. Leakage must be prevented before starting the boiler. If there is a leakage in the plumbing system,boiler must be started after repair.
Yearly Controls : Yearly controls of the boiler must be made by Rima technicians before the season starts. Flue and flue lines must be cleaned before calling technicians for yearly controls. In yearly controls rima technicians apply the following processes.
Burner Door and Burner Connection : In burner connection process there must not be any empty space left between the front door and the burner barrel.All connection points must be covered with isolation material for avoiding any air leakage possibility. A metal flange is used for easier assembling of the burner to the door.
