Instructions for installation and servicing ecoTEC
5.4.3 Filling the heating system in ecoTEC pro com-
bination boilers and ecoTEC plus system boil-
ers
The ecoTEC pro combination boilers and the ecoTEC
plus system boilers do not come with a filling device. In
these appliances, water is filled in the heating system
through a filling pipe provided onsite.
• Join a hose between a cold water dispensing valve and
the filling pipe of the heating system.
• To fill, first open the cold water dispensing valve.
• Open the stop valve on the filling pipe, so that water
flows into the heating system. Fill the heating system
as described in Section 5.4.4.
• After filling, close the stop valve on the filling pipe and
the cold water dispensing valve and remove the filling
hose.
5.4.4 Filling the heating system for the first time
Note
As long as there is insufficient water pressure
in the heating system, the display indicator
changes between the error message F.22 and
the actual pressure indicator when the appli-
ance is on.
Fill the heating system as follows:
• Open all heating element thermostat valves.
• Check if both stop valves on the heater are open.
• Only in ecoTEC plus combination boilers: Connect the
filling pipe as described in Section 5.4.2.
• Only in ecoTEC plus system boilers and in ecoTEC pro
combination boilers: As described in Section 5.4.3 join
a hose between the cold water dispensing valve and
the filling pipe of the heating system.
• Open the cold water dispensing valve.
• Slowly open the filling valve and let the water flow into
the heating system. Bleed the lowest radiator until the
water flows out at the bleed valve without bubbles.
• Bleed all other radiators until the heating system is
completely filled with water, all bleed valves have been
shut and the manometer pointer is in the centre of the
dark grey area. Bleed the heating pump by loosening
the central screw. Close the filling valve and the cold
water dispensing valve.
• Loosen the cap of the pump A.A.V. (automatic air vent)
(the appliance is ventilated independently by the pump
A.A.V. during continuous operation).
• Check all connections and the entire system for leaks.
5.5 Initial system flush (“cold”)
Note
The complete heating system must be flushed
out at least twice: once cold, and once hot as
instructed below.
• Check if all radiator thermostatic valves and both serv-
ice valves on the boiler are open.
• Connect a hose to the drain valve located at the low-
est position of the heating system.
• Open the 1/2” BSP drain taps and all vent valves on
the heating elements and allow the water to flow out
of the heating system and the boiler quickly and com-
pletely to remove all installation residue from the
heating system before commissioning the boiler.
• Close the 1/2” BSP drain taps.
• Fill the heating system again with water as described
in Section 5.4.4.
• Check that the pressure relief valve of the heating sys-
tem is working by turning the handle on the valve.
• Check the pressure in the heating system and fill
water if needed.
• Close the filling valve and the cold water dispensing
valve.
5.6 Filling the condensate siphon

Fig. 5.4 Filling the condensate siphon
Danger!
Note that if the boiler is run with an empty
condensate trap there is a danger that fumes
might escape into the room and cause poison-
ing. For this reason, it is important to ensure
that the trap is topped up each time the unit is
cleaned.
• Remove the lower part ( 1 ) of the condensate siphon by
turning the bayonet catch in anticlockwise direction.
• Fill the lower part with water until about 10 mm below
the upper edge.
• Refit the lower part of the condensate siphon.
