1.2 Operating the boiler (Fig. 1)
1.2.1 Switching on
For “E” models
• Open the fuel stopcock.
• Switch the boiler’s main switch 1 to
the ON position (the switch lights up).
• Turn the heating water temperatu-
re adjustment knob
3 to set the tem-
perature required for the heating
system.
• Set the ambient temperature using
the ambient thermostat (if there is
one).
• When the heating system calls for
heat the heating request light
4
comes on.
• When the burner is operating, the
burner operation light
8 comes on.
For models with a thermoelectric
valve:
• Open the fuel stopcock.
• Make sure that the main switch is
in the OFF position (the switch is not
lit up).
• Remove the front panel on the boiler.
This allows access to the gas valve
and the piezoelectric device and the
pilot burner can be switched on.
• Turn the cover over the pilot burner
so that it can be seen through the
relevant hole.
• Pushing the gas valve knob gently,
rotate it anti-clockwise from the •
(off) position to the (pilot) posi-
tion.
• Hold the knob down and push the
piezo until the pilot burner is bur-
ning.
• Hold the knob down for about 20
seconds.
• After releasing the knob turn it anti-
clockwise to the (main burner)
position.
• Put the cover plate for the pilot
burner back in its original position.
• Replace the front panel on the boiler.
• Switch the boiler’s main switch 1 to
the ON position (the switch lights up).
• Turn the heating water temperatu-
re adjustment knob
3 to set the tem-
perature required for the heating
system.
• Set the ambient temperature using
the ambient thermostat (if there is
one).
• When the heating system calls for
heat the heating request light
4
comes on.
• When the burner is operating, the
burner operation light
8 comes on.
Please Note : When igniting the bur-
ner after the boiler has been out of
use for a long period of time, espe-
cially in the case of LPG boilers,
there may be airlocks in the pipes.
The boiler’s burner may cut-out a
few times. Restart the burner using
the reset button (see the following
paragraphs).
1.2.2 Switching off
For “E” models
Set the main switch on the OFF
position (the switch is not lit up).
If necessary, shut the fuel stopcock.
For models with a thermoelectric
valve:
On these models, when the main
switch is on the OFF position (switch
not lit up) the main burner is extin-
guished but the pilot burner stays
alight.
If you wish to extinguish the pilot
burner as well, after setting the main
switch to the OFF position, remove
the boiler’s front panel and turn the
gas valve knob to the • (off) position
by turning it clockwise.
1.2.3 Burner cut-out
When any functioning faults arise
the boiler’s burner cuts out automa-
tically. On “E” models the cut-out
light
7 comes on. Should this hap-
pen, proceed as follows:
• First check the fuel supply, make
sure that the gas stopcock is open
and that the gas mains have gas in
them by lighting a cooking ring in the
kitchen, for example.
• Having checked the fuel supply,
reset the burner by pushing the
reset button
2 on the control panel.
Models with a thermoelectric valve
do not have any cut-out indication
light.
The boiler must be re-ignited as per
instructions given in paragraph
1.2.1
and this can only be done 60
seconds after it has gone out (auto-
matic safety device).
If the equipment does not restart
and cuts out again, after trying three
times contact an authorised Service
Centre or qualified personnel to
carry out maintenance.
If the burner cuts out frequently this
is a sign that there is an ongoing
operating fault.
Contact qualified personnel or an
authorised Service Centre for main-
tenance.
1.2.4 Cut-out do to overheating
Should the red cut-out light 5 indica-
ting overheating come on, this
means that the safety thermostat
cut-out has tripped and must be
reset manually. This is due to an
operating fault and an authorised
Service Centre or qualified person-
nel must be contacted for mainte-
nance.
