7. RESET AFTER LOCKOUT
When the integrated control module has shut the system
down and gone into lockout, the system must be manu-
ally reset before the unit will restart. The system can be
reset by turning the system power off for more than
1 second, or by removing 24VAC from the control for
more than 1 second, or by removing the thermostat call
for heat for more than 1 second but less than 20 seconds.

8. RESET AFTER BURNER BOX LIMIT SHUTDOWN
If the furnace shuts down, one thing that can be checked
is the burner box temperature limit switch. It is located
on the bottom of the burner box. The vent and combus-
tion air inlet terminations should be checked for block-
age. If blockage exists, clear the problem and then the
reset button may be depressed. If there is no block-
age of the terminations, the limit switch must be
reset by a qualified servicer.
