3.5 — Automatic Shutdown
Limit or operating controls open:
1. Fuel valves close. Main fuel lamp goes off. Flame safeguard timer starts.
2. Flame safeguard timer and burner motor stop. Burner is ready for startup on the next call for heat.
3.6 — Manual Shutdown
1. Turn gas/oil selector switch off. The burner shuts down in Automatic Shutdown as above.
2. When the burner motor stops, close all manual valves.
3.7 — Safety Shutdown
1. If at any time during the operating cycle a flame failure occurs, the burner shuts down as in Automatic Shutdown,
with an additional post-purge, and the flame failure lamp is energized.
A. The lockout switch on the flame safeguard control must be manually reset before the burner will fire again.
Read the Flame Safeguard manual and fully understand its contents before attempting to operate this equipment. If the
manual is not read and understood, serious personal injury or death may result.
Should a starting failure occur for any reason, combustible fumes may fill the combustion chamber. Never attempt to re-
light the burner under these conditions. The combustion chamber must first be purged before re-lighting.
Keep fingers away from the combustion air intake below the damper. The damper is actuated with sufficient force to cause
severe injury. Always make high and intermediate rate adjustments when the burner has reached low fire position. Do not
disturb the low fire setting.
