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 Treatment of Water in d.h.w. c.h. Sys-
tems.
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 we highly recommend
the use of a c.h. flushing detergent in the quan-
tities as specified by the appropriate manufac-
turer, 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

The full length of the condensate pipe should be
check for leaks.
The boiler has a built--- in condensate trap pro-
vided with a ball valve that prevents the escape of
combustion products when the trap is empty.
It is however recommended that any other trap
in the drain system is correctly filled with water
before to run the boiler.

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.
The appliance operation light 10 will flash
every 4 seconds.
2 Turn the function selector 8 as in Fig. 7.4. The
appliance operation light 10 will flash every 2
seconds.
