GAS TRAIN,
(as EN 676)
The gas train is supplied separately, for its adjustment see the enclosed instructions.
3.5
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 6.
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:
cable clamp (1) is positioned correctly;
the tube is positioned correctly so that there are no
restrictions likely to impede air flowing to the pres-
sure switch.
WARNING
If necessary, cut the tube to the right size.
