Condensate Pipe And Traps; Lighting The Boiler - Biasi M110B.24SM/C User Manual And Installation Instructions

Commissioning
5 Gradually open stopcock at the filling point
connection to the c.h. system until water is
heard to flow; do not open fully.
6 Close the condensing heat exchanger air
purger valve 17 (Fig. 7.2) when water begins to
flow out.
7 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.
8 Purge the air from the pump by unscrewing the
pump plug 28 (Fig. 7.3); release the pump
shaft by turning in the direction indicated by
the arrow on the information plate.
9 Replace the pump plug.
10 Continue filling the system. The actual reading
should ideally be 1,3 bar and not less than 0,3
bar.
11 Close all air release valves on the c.h. system.
12 Inspect the boiler and the system for water
soundness and remedy any leaks discovered.
13 Cold flush the system to remove any loose par-
ticles and any system debris before starting the
boiler for the first time
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 filling are
completed turn on the c.h. system and run it
until the temperature has reached the boiler
operating temperature. The system must then
be immediately flushed through.
This procedure must be repeated twice more.
During this operation a c.h. flushing detergent
must be used in the quantities as specified by
the appropriate 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 im-
portant to ensure the system water is treated with
a suitable scale and corrosion inhibitor in accord-
ance with the manufacturers instructions.

Condensate pipe and traps

Before to run the boiler, ensure that the built in con-
densate trap and any other trap in the drain sys-
tem is correctly filled with water.
Fill the built in condensate trap by removing the
flue elbow and pouring a cupful of water into the
flue outlet (Fig. 7.4)
Fig. 7.4
In alternative, to avoid the removal of the flue
elbow, pour the water through the flue sampling
point (Fig. 7.5)

Lighting the boiler

Some products incorporate an anti cycling time
delay. It is normal when first switching the boiler on
for the boiler to operate on heating for a few sec-
onds then switch off. After 3--- 4 minutes has
elapsed the boiler will then re ignite and operate
perfectly normally. The ignition delay cycle does
not prevent normal operation of the boiler to pro-
vide d.h.w..
If external controls are fitted (e. g. Timeclock, room
thermostat) ensure they "call for heat".
1 Turn on the electricity supply to the boiler,
switching on the fused spur isolation switch.
