  • Page 5: General Information

    First of all, we would like to thank you for choosing the RIMA brand. In this manual, you will find installation and operation information for the RIMA branded wall and floor type natural gas condensing heating boilers with aluminum cast fins manufactured by ÖNMETAL.

  • Page 6: Explanations Of The Symbols

    • In the installation, a sediment trap shall be placed in the secondary circuit after the balance vessel and an air separator shall be placed in the primary circuit after the balance tank. • Commissioning and adjustment of the boiler shall be performed Authorized Service Centers of RIMA. See p.58 •...
  • Page 7 • All electrical and electronic controls are supported on the control panel located at the top of the boiler. • The cleaning of the installation is of utmost importance for the transformation projects from boilers with solid fuel or liquid fuel to boilers with gas fuel. The installation shall be washed, any leaks shall be detected and repaired and a plate type heat exchanger shall be used.

  • Page 8: Points To Be Considered During Handling And Transport

    • Supply of cold water to the boiler shall be performed when the boiler is cold. • It is possible that oxygen may pass through the floor heating pipes into the water. Oxygen in the water causes corrosion of the boiler. Therefore, if the boiler is to be used in a floor heating system, a heat exchanger shall be added to the circuit and mixing of the boiler water and installation water shall be prevented.

  • Page 9: Cascade Configuration

    1.3.4.Cascade Configuration The use of wall and floor type condensing boilers in central systems is increasing every day. Condensing boilers designed for this purpose provide high capacities with low space requirement. An advantageous and economical heating is ensured by reaching a capacity of 187 kW in one boiler and a max. capacity of 2,992 kW with a cascade system.
