GREENSTAR OILFIT INSTALLATION INSTRUCTIONS
ROOM SEALED FLUE
MEASURING & CUTTING
1 All horizontal flue sections must rise at
52mm for each metre away from the
boiler to ensure that condensate flows
back into the boiler for safe discharge
via the condensate waste pipe.
Measuring the flue:
2 Measure the flue length (L) required from
the flue opening outside the building (H)
to the outer boiler casing (E) at the
required flue outlet position (A, B, C or D).
Add dimension shown for the terminal
projecting outside the building (H),
120mm for a horizontal terminal or 600mm
for a vertical terminal.
Add dimension 'X' to the flue length, as
shown for flue outlet A, B, C or D in the
table opposite (to allow the flue to fit to the
outlet/elbow inside the boiler casing).
Reducing the terminal length:
Mark length required from the end of the
terminal flue outlet and cut square, taking
care not to distort the tubes.
Remove any burrs and chamfer the outer
edges of the tubes to assist ease of
connection and prevent seal damage.
Reducing extended flue tube length:
Only cut straight extension tubes
3 Mark flue extension (K) to measure and cut
both inner and outer tubes square (at the
opposite end to the seal) taking care not
to distort the tubes.
Remove any burrs and chamfer the outer
edges of the tubes to assist ease of
connection and prevent seal damage.
