Page 16: Operating Faults
OPERATING FAULTS The integrated control system is self-checking. The cycle from start up to stability requires 66 seconds. The burner will go into lockout under the following circumstances: a) Flame failure b) The ionization probe is grounded c) Opening of the air pressure switch d) The burner shuts down if gas pressure switch (if used) opens because of insufficient gas pressure in the supply lines. - Page 17 OWNER INFORMATION AND ROUTINE MAINTENANCE SAFETY LOCKOUT This burner is equipped with multiple interlocking safety devices. In the event of a failure in the flame, or any blockage of the combustion air supply, the burner will “lock out” in a safety condition. In such an event, an illuminated red button will show on the front of the red cover.
