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

Provide an even  layer  throughout the entire boiler depth. If the fuel suddenly turns into dark red blaze, open

partially the secondary air supply  rosette in the stoking door. When the flame turns yellow, shut the secondary

air  supply rosette again. When  the boiler  has reached the required  output,  it is suitable to partially shut the

flue thrust flap to prevent heat from unnecessarily escaping into the chimney.

• Do not start the boiler without connecting the boiler to the chimney

              • Do not start the boiler without connecting the boiler to the chimney.

              • Control chimney connections before starting the boiler.

              • Adjust the chimney  blow as requested level. If  chimney blow is under  mentioned  levels try  not to

                use the boiler.

Setting the outlet water temperature

When  the required  outlet   water  temperature is say  60 °C, heat up the boiler  to a temperature for instance

5 °C   higher  than the   required  temperature  of  60 °C ( measured  on the  thermometer on  the boiler outlet

pipe). Then  turn  the   control  knob to  65 °C  and  check  whether    the chain is stretched and the regulating 

hatch  completely shut.  This  position  of the chain and regulating hatch is fine-adjusted by turning the control

knob.Then let  the  regulation  process work.  When  the water  temperature  drops,  the regulating  hatch  will

start  opening  by the  tension  applied by the regulator on the  chain.  When the  water temperature  suddenly

rises,  the   regulating  hatch  will  start  opening.   And   the  hot  water  temperature   on  the  boiler  outlet  is

rises,  the   regulating  hatch  will  start  opening.   And   the  hot  water  temperature   on  the  boiler  outlet  is

controlled.

Stoking

First shut the regulating hatch;  this will shut  supply of combustion  air into the boiler. Then open the chimney

flap  completely. Partially  open the  stoking door and wait until  all combustion gases have been sucked from

the combustion  chamber into the chimney.  Only then open the stoking door completely and start stoking the

boiler.  After shutting the stoking door, set the chimney flap again and restore the functioning of the regulating 

hatch.

               • Boiler doors must not be held open as the  boiler is continously working.

   • Provide a minimum 5 cm gap to be between top point of the fuel and ceiling of stoking chamber 

                 when boiler is stoked.

Overnight heating mode

This  mode  is  used  when you want to  maintain  the   fire in the  boiler for instance  over  night. First  scrape

all ash out  of the  combustion chamber, with  the chimney flap completely opened. Then stoke the boiler with

fuel and   shut the  boiler  up  completely.  Then  shut the  chimney flap  and also almost  shut  the  regulating

hatch. This will reduce  the chimney thrust and  restrict the supply of combustion air.Shut also the secondary

air supply rosette in the stoking door To restore the boiler’s required output just open the chimney flap

air supply  rosette in the  stoking door.  To  restore  the boiler s   required output,  just  open the  chimney flap

and partially open the regulating hatch to the required boiler output. 

Removing solid combustion residuals

This is done by removing  and emptying  the ashtray situated underneath the stoker in the ash compartment.

This must be  done on a regular  basis  to  prevent  ash from accumulating and  blocking  the supply of air to 

the combustion chamber from underneath the stoker.
