FLUE LENGTHS

The flue systems have different maximum flue lengths

The Greenstar series has the option of two horizontal

horizontal 80/125 RSF (telescopic) flue system and two

vertical RSF (60/100 or 80/125) flue systems:

Refer to the Flue options in table 21 for the straight flue

lengths required to achieve the maximum flue length.

accessible, provision must be made for

service and inspection.

have at least one inspection hatch no less

than 300mm square.

B Flue joints within the void must not be

more than 1.5 metres from the edge of

the inspection hatch.

B Inspection hatches should be located at

changes of direction.

B If this is not possible, bends should be

viewable from both directions.

2 metres of straight flue
