CONVERTING THE APPLIANCE GAS TYPE
To convert the appliance to another gas type it is
necessary to change the burner injector and adjust
the gas valve. It is also necessary to enter the
appliance engineer mode and change the fan speed
at the maximum output.
●
To change the injector see 6.12.1
●
To change parameters see 7.3.1
●
To adjust CO
2
value see 7.4.1-2
10.4
GAS SUPPLY
The gas supply must be connected to the appliance
by a competent LPG installer and must be of
sufficient size to supply the appliance at its maxi-
mum output. An existing supply must be checked
to ensure that it is of adequate size to deal with the
maximum rated input of this and any other appli-
ances that it serves.
10.5
GAS SUPPLY INSTALLATION
The entire installation including the meter must be
purged and checked for gas soundness.
10.6
ADJUSTING THE GAS VALVE
THE GAS VALVE MUST BE SET-UP OR AD-
JUSTED WITH THE AID OF A PROPERLY CALI-
BRATED FLUE GAS ANALYSER.
Isolate the appliance from the electrical supply and
remove the appliance casing as described in 4.7.1.
Set the flue gas analyser to read CO
2
and insert the
probe into the flue analysis test point (see fig. 1).
Restore the electrical supply to the boiler and switch
off the boiler. Push INFO and MODE buttons at the
same time for 10 seconds to enter the adjusting
menu. The display shows “CodE” (see fig. 49).
Select the adjusting password by turning the DHW
temperature control and confirm it by pushing MODE
button.
10.6.1 MAXIMUM SETTING
Select the HH parameter by turning the DHW
temperature control and confirm it by pushing MODE
button. The boiler starts at the maximum power, the
CO
2
reading should be as shown in the table above.
If the CO
2
reading is correct, press the MODE
button to exit the maximum setting. If the CO
2
reading is incorrect, the maximum gas pressure
must be adjusted as follows:
●
using a suitable screwdriver, very slowly turn the
maximum adjustment screw (see fig. 43) – clock-
wise to decrease, counter clockwise to increase –
until the correct value is displayed on the CO
2
analyser (allow time for the analyser to stabilise).
IMPORTANT
A GAS SOUNDNESS CHECK MUST BE CAR-
RIED OUT.
10.6.2 MINIMUM SETTING
Select the LL parameter by turning the DHW tem-
perature control and confirm it by pushing MODE
button. The boiler starts at the minimum power, the
CO
2
reading should be as shown in the table above.
If the CO
2
reading is correct, press the MODE
button to exit the minimum setting. If the CO
2
reading is incorrect, the minimum gas pressure
must be adjusted as follows:
