Train electrical supply

The gas train's supply cables can be fed to the right or left of the
burner (Fig. 17).
Depending on the entry point, the cable clamp with pressure test
point (1) and simple cable clamp (2) may need swapping over.
Consequently, you must make sure:
 the cable clamp (1) is positioned correctly;
 the tube is positioned correctly so that there are no restric-
tions likely to impede air flowing to the pressure switch.
If necessary, cut the tube to the right size.
