Open-hearth plate for burning logs or solid fuel - has two superimposed slotted plates adjustable for min or max draught control

摘要

The box (1) has a bottom plate (2) with longitudinal air slots (3). The plate additionally has two slotted holes for ears fixed to a plate (6) with longitudinal air slots (7). After placing the slotted plate (6) on the bottom plate, it is slidable over the bottom plate. An external handgrip fitted to one ear enables the user to regulate the precise draught requirement. The slots taper downwards to facilitate ash clearing, which is carried out by a quick sliding movement between the plates.
