5.4.2. Changing the combustion adjustment elements. Models ED260, ED340, ED460 and ED660
Changing the type of fuel gas requires modifying the combustion adjustment elements: the injector and the
Venturi. (Figure 5.6.)
This should be carried out as follows:
 Remove the back cover (ED260 and ED340) or the
intermediate back cover (ED460 and ED660) as appropriate.
 Replace the gas injector (A) with the appropriate injector for
the new type of gas (see injector values in the table in Section
4.3.1).
 Change the position of the Venturi (B) in accordance with
Measurement E in the enclosed table. Set the position of the
Venturi using the screw C.
 On models ED460 adapted for propane gas, the gas deflector
(D) must also be fitted. (Except for machines installed in
Australia, see next paragraph).
Australian Machines: On ED260 and ED460 models adapted for
propane gas, the 120º gas deflector (D) must also be fitted.
Fig. 5.6
CAUTION!
THE GAS VALVE ADJUSTMENT MUST BE LEFT UNALTERED.
 Replace and secure ALL the covers.
 Start up the machine and select a program with temperature to cause the burner to ignite (see
directions in Chapter 8).
 Based on the result of the analysis of the combustion gases, if necessary, adjust the position of the
Venturi until the correct amount of combustion is obtained.
