Notes on safety for the first start-up
5.2
Burner firing
Having completed the checks indicated in the previous heading,
the ignition pilot of the burner should fire.
➤
Set switch to "LOCAL" (Fig. 31).
If the motor starts but the flame does not appear and the flame
safeguard goes into lock-out, reset and wait for a new firing at-
tempt.
Pilot adjustment has been illustrated on page 25. Having adjusted
the pilot, reconnect the main valve and ignite the main flame; it
might require several attempts to purge the air from the gas lines
or to adjust the valve with little gas.
Once the burner has fired, now proceed with calibration operations.
