TESTING
Check the shut-down of the burner by opening the thermostats,
and the lock-out by opening the connector (
CN3 ) inserted in the
red cable of the probe placed outside of the control box.
NOTES
The burners have been type-approved for intermittent opera-
tion. 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 ensures 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 ).
