Condensate Pipe And Traps - Biasi RIVA ADVANCE HE M110B.24SM/C User Manual And Installation Instructions

• Lift the cap on the automatic air purger
valve 25 in Fig. 7.3 one full turn and leave
open permanently.
Fig. 7.3
• Gradually open stopcock at the filling point
connection to the c.h. system until water is
heard to flow; do not open fully.
• Close the condensing heat exchanger air
purger valve 17 (Fig. 7.2) when water be-
gins to flow out.
• Open each radiator air vent starting at
the lowest point of the system and close
it only when clear water, free of bubbles,
flows out.
• Purge the air from the pump by unscrew-
ing the pump plug 28 (Fig. 7.3); release the
pump shaft by turning in the direction indi-
cated by the arrow on the information plate.
• Replace the pump plug.
• Continue filling the system. The actual
reading should ideally be 1,3 bar and not
less than 0,3 bar.
• Close all air release valves on the c.h.
system.
• Inspect the boiler and the system for wa-
ter soundness and remedy any leaks dis-
covered.
• Cold flush the system to remove any
loose particles and any system debris be-
fore starting the boiler for the first time.

COMMISSIONING
The flushing procedure must be in line
with BS7593:2006 Treatment of Water in
d.h.w. c.h. Systems.
When the installation and second fill-
ing are completed turn on the c.h. sys-
25
tem and run it until the temperature has
reached the boiler operating tempera-
ture. The system must then be immedi-
ately flushed through.
This procedure must be repeated twice
more.
28
During this operation we highly recom-
mend the use of a c.h. flushing detergent
in the quantities as specified by the ap-
propriate manufacturer, whose function
it is to dissolve any foreign matter which
may be in the system.
INHIBITION (Primary Heating Circuit)
On the final refilling of the heating system it
is important to ensure the system water is
treated with a suitable scale and corrosion
inhibitor in accordance with the manufactur-
ers instructions.
7.6
The full length of the condensate pipe
should be check for leaks.
Before to run the boiler, ensure that the
built in condensate trap and any other
trap in the drain system is correctly filled
with water.

Condensate pipe and traps

Fill the built in condensate trap
by removing the flue elbow and
pouring a cupful of water into
the flue outlet (Fig. 7.4).
