This operates when TL is faulty.
NOTE:
The burner is delivered preset for single-stage operation
with a jumper inserted in the terminal strip, see (Fig. 23). If
two-stage operation is required, remove the jumper between
terminals 8-9 and insert the control device TR in its place to
command the 2nd gas oil solenoid valve.

the electricity supply line. Any inversion would
cause a lockout due to firing failure.
