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
th b ti h b i t th hi O l th th t ki d l t l d t t t ki th 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.
