SECTION SEVEN – Troubleshooting
7-1
Read Me First!!
NOTE: Connecting a single-voltage (115VAC) heater
to a 240VAC line, or installing the black 120 volt plug
in the control box of a dual-voltage heater and then
connecting the heater to a 240 volt line, will destroy
the transformer, control board, and ignition control
module, and will void the warranty. If you install the
red 240 volt plug in a dual-voltage heater 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. Single-volt-
age heaters operate on 120VAC ONLY. Dual-volt-
age heaters will operate on either 120 Volts AC or
240 Volts AC.
2. Remove the covers and check for a 12-pin plug in
the back of the control box.
A. If the control box does
not
take a plug, the heater
is a single-voltage heater and will operate on
120VAC ONLY.
B. If the control box
does
take a plug, the heater is
dual-voltage. The plug must match the incoming line
voltage. The BLACK plug is for 120 volts, the
RED plug is for 240 volts.
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 BLACK
plug is for 120 volts, the RED plug is for 240
volts.
