Condensate, gas and water connections
CONDENSATE CONNECTION:
Refer to figures 23 and 24.
The condensate pump [7] fills up and periodically discharges through
the flexible condensate pipe [8] between 200mm to 4500mm from
floor level. After this point the condensate flows, due to gravity, down
the 21.5mm plastic pipe to the outlet.
▶ Fit the bayonet connector on the end of the condensate waste pipe to
the condensate pump. Push down and rotate clockwise until the
connector is locked.
▶ Route and secure condensate waste pipe [8] with clips supplied to
prevent kinking or restriction.
▶ Cut off any excess pipe [8].
▶ Fit the condensate waste pipe [8] to adaptor [11] and secure with
clip [10].
▶ Connect adaptor [11] to 21.5mm plastic pipe and terminate
appropriately as described in section 3.4.

FLUE LENGTH
▶ Do not exceed the maximum straight length for a
horizontal or vertical flue or a 60mm plume

relevant Installation, Commissioning and Servicing
Instructions manual or addendum.
Cutting the flue to an exact measurement is not normally
required as the telescopic flue terminal can allow for
some adjustment.
