When the weather is warm, or if you have a marginal chimney, you do need a full time combustion blower.. If your stoker is fireing to make heat several times an hour, then your coal will burn very well and completely.. But if you have warm weather or a marginal chimney pulling air through the fire, then the additional combustion air is needed to keep the idle fire burning well.
