Through a narrow slot on the top inside edge of the glass, the air-wash system supplies most of the air to the fire. It is designed to make the combustion air sweep down between the glass and the fire so that soot cannot stick to the glass. Airwash systems help to keep the glass on a stove clean.

A wood-burning stove (or wood burner or log burner in the UK) is a heating or cooking appliance capable of burning wood fuel and wood-derived biomass fuel, such as sawdust bricks.

What is the difference between wood burner and multi fuel?

Woodburners have a fixed grate and no ashpan, since wood burns best on a bed of ashes.

This system also allows the easy removal of the ash from below using a removable ashpan.
