DIAGNOSTIC ALARMS: IGN
NOTICE: Installing the black 120 volt plug in the control box and
then connecting the heater to a 240 volt line will destroy the trans -
former, control broad, and ignition control module, and will void the
warranty. If you install the red 240 volt plug and then connect the
heater to a 120 volt line, the heater will not operate.
READ THE FOLLOWING CAREFULLY:
1. Check the line voltage to your heater. This heater will operate
on either 120 Volts AC or 240 Volts AC.
2. Remove the covers and check the 12-pin plug in the back of the
control box. The plug must match the voltage in the heater circuit.
3. If the 12-pin plug is not plugged into the back of the control
box, select the correct plug from the bag in the control box
and plug it in. The BLUE plug is for 120 volts, the RED plug
is for 240 volts. See page 43.
