NOTES
The burners have been type-approved for intermittent operation. This means they
must stop at least once every 24 hours in order to allow the electrical control box
to check its efficiency on start-up. The boiler limit thermostat (TL) normally en-
sures the burner halts. If this does not happen a time switch halting the burner at
least once every 24 hours must be applied in series to limit thermostat (TL).
