FUnCTIOn OF STOvE

n Primary air is required for heating up the stove and for burning mineral fuels e.g. lignite
briquettes. The primary air is sucked into the fire chamber from below, in most cases
through the grate.
n Secondary or "glass cleaning" air is required for burning long-lasting materials such as
logs, wood briquettes and lignite briquettes. Secondary air enters the fire chamber from
above. It also serves to keep the glass window clean for as long as possible (see notes on
page 14).
n Tertiary air is additional secondary air. With most stoves, the tertiary air is set by the
manufacturer and cannot be changed. However, this varies from one stove to another.
n Depending on type, DROOFF stoves are fitted either with a shaker grate or a fixed grate.
The primary air flowing through the grate to the fire helps to cool the grate. For this reason
it should be kept free at all times.
n All DROOFF stoves are fitted with an ash box. The ash falls through the grate into the box.
The amount of ash created depends on the type and amount of fuel burned and should
be emptied every few days.
n DROOFF stoves are designed according to type 1. This indicates a simple but effective
safety system. Should you forget to close the stove door after stoking it, it will close auto-
matically thereby preventing burning wood from falling out. However, always make sure that
the door to the fire chamber is properly closed at all times.
n Most DROOFF stoves can be connected to an external source of fresh air. An external air
supply is generally required when the space where the stove is standing is very confined. In
this case, most of the air is supplied to the fire chamber from outside. A qualified heating
engineer will tell you whether an outside connection is necessary in your case.
Important note: if your stove does not receive air from outside, make sure that the room
has a sufficient supply of fresh air. The stove requires approximately 4 cubic metres of
air to burn 1 kg of wood!
