9.3 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 nozzles see 6.12.1
- To change parameters see 7.3.1
- To adjust CO
value see 7.4.1-2

9.4 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 maximum 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 appliances that it serves.
9.5 GAS SUPPLY INSTALLATION
The entire installation including the meter must be purged and
checked for gas tightness.
9.6 ADJUSTING THE GAS VALVE
THE GAS VALVE MUST BE SET-UP OR ADJUSTED WITH THE
AID OF A PROPERLY CALIBRATED 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
and insert the probe into the flue analysis test point
2
(see fig. 1). Restore the electrical supply to the boiler and switch off
the boiler. Push and
to enter the adjusting menu. The display shows "CodE". Select the
adjusting password by turning the encoder and confirm it by push-
ing ENTER button.

9.6.1 MAXIMUM SETTING
Select the HH parameter by turning the encoder and confirm it by
pushing ENTER button. The boiler starts at the maximum power,
the CO
reading should be as shown in the table above.
2
If the CO
reading is correct, press the ENTER button to exit the
2
maximum setting. If the CO
2
pressure must be adjusted as follows:
- using a suitable screwdriver, very slowly turn the maximum adjust-
ment screw (see fig. 41) – clockwise to decrease, counter clockwise
to increase – until the correct value is displayed on the CO
(allow time for the analyser to stabilise).
IMPORTANT
A GAS TIGHTNESS CHECK MUST BE CARRIED OUT.
9.6.2 MINIMUM SETTING
Select the LL parameter by turning the encoder and confirm it by
pushing ENTER button. The boiler starts at the minimum power, the
CO
reading should be as shown in the table above.
2
If the CO
reading is correct, press the ENTER button to exit the
2
minimum setting. If the CO
2
pressure must be adjusted as follows:
- using a suitable screwdriver, very slowly turn the minimum
adjustment screw (see fig. 41) – clockwise to increase, counter
clockwise to decrease – until the correct value is displayed on the
CO
analyser (allow time for the analyser to stabilise).
2
- using the procedure detailed in 9.6.1, check that the maximum
setting correct value is still being obtained. If not, repeat the above
procedure.
reading is incorrect, the maximum gas
reading is incorrect, the minimum gas
