Rima Heating Systems S.MAX Series, Installation, Operation & Maintenance Manual

Operating Instructions    

S.MAX Series Boiler –  General features

• S.MAX series  solid  fuel fired boiler is designed for heating  both residential and industrial buildings.

• Besides professional installation,  precondition  for correct  functioning of  the boiler  is the required chimney

thrust and correct operation.

• S.MAX series  solid fuel fired  boiler  is designed  for heating  systems  which are  suitable  for forced  circulation

systems only.

• S.MAX series boilers  are available in seven output series  ( determined by the number of segments  4,5,6,7,

8,9,10 )  from 38 to 95 kW.

• The   cast  iron  boiler  body  comprises of  segments   and  serves  as  a  combustion  chamber  (  including 

combustion gases routes ), and at the same  time as a water reservoir ( including water  routes ). Segments

combustion gases routes ), and at the same  time as a water reservoir ( including water  routes ). Segments

are of  three types – front and rear, inserted   between which are 1 to 8 middle segments  (of the same kind).

By assembling and joining together an appropriate number of segments, a boiler body of the required size is

constructed ( both the  combustion  chamber and the  water reservoir ).  Assembled  boiler body is equipped

with necessary pipe  sections for water  connection. It  also has brackets for fitting  thermostat  sensors  and

brackets on  feet for fastening the boiler to the base. Attached to  the  cast iron boiler  body are  sheet  metal

covers which are  fitted  on the inside  with thermal insulation.

• To ensure that the boiler  functions  correctly  and runs  economically, it is important  that its nominal  output

is equal to the thermal losses of the heated premises.

• Choosing a boiler of  insufficient output will result in inadequate  heating of the premises, and thus  failure to

provide a heating comfort.

• Choosing  a boiler of  unnecessarily  high output  will result in the boiler not  running in full output,  and as a

consequence in tarring and dewing.

Recommended fuel

• Recommended fuels for S MAX boilers are coal coke and firewood

• Recommended fuels  for S.MAX boilers are coal, coke and firewood.

• Optimal coal and coke granularity is 24 – 60 mm.

• Optimal firewood  size is logs  of  diameter  40 – 100 mm. Their length will depend on  how many segments

the boiler have.

• Fuel must be stored  in a dry place. To reach the boiler nominal output, water content in  firewood  must not 

exceed 20% .

• Approximate  stoking  intervals  ( reffered  to as  Burning  Time )  are  shown in the Technical  Data Table on  

page 4.

• The boiler is stoked manually.

Please note  

The boiler is not intended for burning any type of waste.
