3.4 GAS TRAIN ELECTRICITY SUPPLY
The gas train's power cables can be fed to the right or left
of the burner, as illustrated in figure 5.
Depending on the entry point, the cable clamp with pres-
sure test point (1) and simple cable clamp (2) may need
swapping over.
Consequently, you must make sure:

cable clamp (1) is positioned correctly;

the tube is positioned correctly so that there are no
restrictions likely to impede air flowing to the pressure
switch.
WARNING
If necessary, cut the tube to the right size.
