SYSTEM OPERATION
11
Direct Spark Ignition (DSI) Systems
DCG units are equipped with a direct spark ignition system.
Ignition is provided by 22,000 volt electronic spark. A flame
sensor then monitors for the presence of flame and closes
the gas valve if flame is lost.
The system may be controlled by most good heating and
cooling thermostats with an adjustable heat anticipator.
NOTE:
Some night setback thermostats that do not have a
common terminal use a power robbing circuit in the off cycle
to maintain the batteries. This type of thermostat may interfere
with the operation of the ignition control module and should
not be used.
HIGH VOLTAGE!
Disconnect ALL power before servicing
or installing this unit. Multiple power
sources may be present. Failure to do so
may cause property damage, personal injury
or death.
