mittent operation. This means it shoulds com-
pulsorily be stopped at least once every 24
hours to enable the control box to perform
checks of its own efficiency at start-up. Burner
halts are normally provided for automatically by
the boiler load control system. If this is not the
case, a time switch should be fitted in series to

every 24 hours.

operation, if they are equipped with control box
