: When the PTS / PTU is operated by a thermostat interrupting the line voltage (120V) to the heater then the
post purge function is disabled.
If the flame is not sensed during sequence T3 then the burner will automatically begin re-ignition sequence T2. The
ignition sequence will be repeated three times with a 60 second inter-purge. If the flame is not re-established the
heater will go to lockout.
