Failure to Light- Lockout (DBI Models Only)
1. Should the main burner fail to light, or flame is not
detected during the trial for ignition 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.
IMPORTANT!
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.
NOTE
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.
