*Power depends on quality of fuel. Power depends on time: at the beginning of burning
power output is higher than indicated in a table, boiler puts out the smoke that is hotter than
300
0
C, therefore raisin residues burn out, fl ue gets warmed up and draft increases (in some
models, direct channel to fl ue is opened). While fuel burns, power of boiler decreases, because
the surface of heat dissipation increases and draft decreases, but when a house becomes warm
the power is suffi cient and additional valve is opened in order to further decrease the power of
boiler.
