Economizer S40

Two pieces of the economizer (crescent) are designed to keep the temperature in the boiler. The boiler operates efficiently with them. When the boiler is installed, we recommend to put them trough the upper doors on the inner tank, which have a special notch for economizers.
When the draught decreases, it is needed to clean heat deprivation gaps between the air heating chamber and the inner wall of the boiler They can be cleaned with a flexible brush through the inner smoke opening above the fuel load door.
