►System Applications
Hot Surface Ignition (HSI)
The thermostat calls for heat and energizes the HSI control. If
system is equipped with prepurge, the purge fan is energized and
power will be delayed thirty seconds before application to the Hot
Surface Ignitor. If prepurge is not selected, the ignitor is powered
within one second. The ignitor heats up and at the end of the
heating period, the redundant and main valves are opened. A
ame must be detected within a xed time period or both valves
close, the ignitor is turned off and the HSI control locks out unless
the system is equipped with retry. Retry indicates the ignition
sequence will be repeated for a total of three tries if ame is
undetected or lost within 30 seconds of ignition.

Typical Wiring for Hot Surface Ignition System
Direct Spark Ignition (DSI)
The thermostat calls for heat and simultaneously energizes the
DSI control module and gas valve solenoid. Sparks at the ignition
electrodes ignite the gas at the main burner. Flame is sensed
through the electrodes by the ame detection circuit and shuts off
the sparking. If ame is not established within a xed time period
(lock-out time) main and redundant valves close, sparking ceases
and the control module locks out.

►System Applications
Standing Pilot
Gas ow to the pilot burner is controlled by a safety valve which
is manually operated and held in by current generated from a
thermocouple placed in the pilot ame. When the thermostat
calls for heat the main valve is energized.

Proven Pilot
The thermostat calls for heat and simultaneously energizes the
pilot valve and the Proven Pilot control. Sparking from the ignition
electrode to the pilot burner ignites the gas at the pilot burner.
Flame is sensed by the ame detection circuit which energizes
the main valve. Main burner gas is ignited and sparking ceases
once a pilot ame is detected.
