Condensate Discharge - Hamworthy Milborne 500 Series Design Installation, Commissioning And Operating Instructions

6.0 Condensate Connection
The condensate water produced by boiler assembly Milborne 501/2 during its normal operation shall be
discharged at atmospheric pressure, i.e. by dripping into a tundish or siphon-shaped container connected as
described in the following procedure:
a) Install a tundish or drip pan under the
condensate discharge system (see position
on installation template).
b) Connect the tundish to the sewage system by
means of a 'U' bend.
c) Install a condensate acid neutraliser if
required by the applicable laws.
The tundish (or drip pan) shall be created and
installed in accordance with the applicable technical
standards.
Plastic polypropylene pipes should be used to
create the condensate discharge system as the
acidity in the condensate will rapidly corrode metal
pipes. Never use copper pipes.
Flue system condensate discharge piping
Should it be necessary to extend the vertical or the
horizontal section of the discharge piping to over 4
metres, create a 'U' bend at the foot of the pipe. The
siphon's useful length must be at least 300 mm. The
'U' bend discharge shall then be connected to the
drainage / sewage system.
Using the condensate discharge kit, HHL Part No.
573407110, detailed in the flue system section, to
make an easy connection to the flue system for
condensate removal.
