Clean boiler chambers from smoke-black and pitch scurf once or twice a month. Clean the

boiler when the fuel is completely burned and the boiler is cooled down to at least +40 °C.

Clean smoke-black and scurf from combustion chambers and flue walls using a scraper

and metal hog. Clean after the doors of the combustion chambers are open and caps of flue upper

openings unscrewed . When finished, check, whether no ashes or smoke-black fell into the ventilator

opening and tightly screw the caps of the flue openings.

Control water pressure in the heating system at least every two weeks. If necessary, fill it

up. If the boiler is not being heated, drain the water off the system when air temperature is below 0 °C!

Emergency extinction of the boiler

If due to any reasons you must immediately extinct the heated boiler, by any means don't

pour water on the kindling wood! The boiler can burst.

It is very convenient to use dry sand for emergency extinction. There should be ~50 kg of

dry sand in the boiler room. Sand not only well isolates burning firewood from the air oxygen but also

cools down the burning zone. Then, when the boiler cools down, sand can be easily cleaned and

removed.
