3 Operating the Boiler

3.1 Sealed Central Heating Systems only

CAUTION. A sealed water system must be filled and
pressurised by a competent person.
Only light the boiler when you are sure that the system
and boiler have been filled and pressurised.
The pressure should read at least 0.7 bar, when the
system is cold. If the needle displays a value below this,
follow the instructions left by your installer to refill the
system. Alternatively your installer should be called to
refill the system.

3.2 All Systems

Check that the electrical supply to the boiler is ON at
the external isolator.
Set any remote heating system controls as required.

Operating the boiler 3

3.3 User Controls

Slide the On / Off control down to the I position to turn
on the boiler. The operating indicator will illuminate
(green) to show that the boiler is on.
The temperature of the central heating water can be
adjusted by pushing the mode button (
radiator symbol is displayed. Pushing the + or - buttons
will then set the water temperature as desired. (Typical
setting temperatures for a normal radiator heating
sytem will be in the range of 60 °C to 80 °C. Note that
set temperatures below 60 °C will not sufficiently heat
any hot water cylinder). To return to the normal mode
push the mode button (
current temperature of water in the boiler.
When the boiler is operating the flame symbol will be
shown in the display. The bar symbol is also shown and
this indicates the modulating output of the boiler. The
boiler will automatically modulate to the output needed
by the heating system - the more bars that are display-
ed, the higher the output.
The ecoMAX pro is a fan flue appliance and the operati-
on of the fan may be heard when the boiler is running
and for a short period after the boiler has stopped.
Should a fault condition occur the operating indicator
will flash red and will be accompanied by an "F" symbol
in the display. To reset the boiler slide the On / Off con-
trol to the Off (O) position and after 5 seconds back to
the On (I) position. The boiler should now operate. If the
fault persists contact your installer / service provider.
The ecoMAX pro has a Holiday / frost mode. If you are
going on holiday and do not want the boiler to be opera-
ted by the external heating controls press the mode but-
ton ( ) until the MODE indicator flashes in the left
hand edge of the display. Then press the + or - button
until the arrow indicator points to the holiday symbol
( ). The boiler will now only operate if necessary for
frost protection of the boiler itself as well as running a
daily pump exercise programme to prevent sticking. It
will not be turned on and off by the external heating
controls. If a system frost protection thermostat has
been fitted this will remain active.

3.4 To Turn the Boiler Off

Normally the boiler will be turned off by the heating
system controls. The mains On / Off control may be used
to switch off the boiler, however it is preferable to leave
the electrical supply on whenever possible to permit
operation of the built-in frost protection and daily pump
exercise programme.
