Broan USA 42000 Series (Ducted) 76 cm Chimney & Hood 423002 (423002 Bisque)

There are two types of outlets

The hood or canopy size depends on the size of the kitchen. Normally a 2 to 4 burner stove/ hob requires a 2 ft chimney whereas a 3 to 5 burner require a 3 ft one. But to absorb maximum fumes or smoke, a chimney should cover the entire gas stove otherwise the heat, smoke or fumes will move out of the canopy area and cannot solve the desired purpose of a chimney.

There are 3 types of controls

• Charcoal or Carbon Filter: These filters are mainly used in re-cycling type of chimneys. They filter out the smoke and absorbs bad odour before it gets recycled back into the room.
• Mesh/ Cassette Filter: There are various layers of mesh that helps in throwing out the smoke and oil particles. Cassette filter is lightweight hence detaching this filter from chimney is very easy.
