Important - Pentair Water MiniMax 75 Manual De Operación Y Instalacion

Operation - Heater (contd.)
Failure to Light- Lockout
1. Should the main burner fail to light, or flame is not
detected during the trial-for-ignition (TFI) period
the control will go into lockout and the valve will
be turned off immediately.
2. Recovery from lockout requires a manual reset by
resetting the thermostat or turning off the ON/OFF
switch for a minimum period of 5 seconds.
IT IS RECOMMENDED THAT NO MORE THAN
TWO IGNITION ATTEMPTS IN SUCCESSION
BE PERFORMED FOR NATURAL GAS
SYSTEMS . BEFORE FURTHER IGNITION
ATTEMPTS WAIT AT LEAST FIVE MINUTES
FOR GAS TO CLEAR.
FOR PROPANE (LPG) SYSTEMS ALLOW AT
LEAST FIVE (5) MINUTES BETWEEN
IGNITION ATTEMPTS FOR THIS HEAVIER-
THAN-AIR GAS TO SAFELY DISSIPATE.
AFTER TWO UNSUCCESSFUL IGNITION
ATTEMPTS WITH PROPANE OPEN THE
BURNER ACCESS DOOR AND WAIT AT
LEAST THIRTY (30) MINUTES BEFORE
REPLACING DOOR TO ATTEMPT FURTHER
IGNITION ATTEMPTS.
Normally the heater will light in the first or
second attempt. And with the exception of a new
installation or one that has been shut down for
an extended period, where there is considerable
air trapped in the gas supply line, unsuccessful
ignition indicates other problems with the
ignition system - such as an unclean ignition
electrode impeding flame sensing.
3. If the thermostat is still calling for heat one hour
after a lockout the control will automatically reset
and attempt to ignite the burner again.
Flame Failure-Re-Ignition
1. If the established flame signal is lost while the
burner is operating, the control will respond within
0.8 seconds. The H.V. spark will be energized for a
trial for ignition period in an attempt to relight the
burner.
a. If the burner does not light the control will
de-energize the gas valve, shutting off the gas
flow, and the control will go into lockout as
described above in "Failure to Light-Lockout".
If flame is re-established, normal operation
resumes.
