The gas train can enter the burner from the right or left side, de-
pending on which is the most convenient, see Fig. 23.
Gas solenoids 8)-9)(Fig. 24) must be as close as possible to the
burner to ensure gas reaches the combustion head within the
safety time range of 2 s.
Make sure that the pressure governor calibration range (colour of
the spring) comprises the pressure required by the burner.
