The electrical information in the shaded area pertains to Export Models only.

•100 and 120 volt models with infinite switch may require tandem (end-to-end) elements, consult factory for applications.

„100 and 120 volt models may require additional switches, consult factory for applications.

†Glo-Ray models 108" through 144" and 100 and 120 volt models of GRAL-84 and GRAL-96 contain tandem (end-to-end) elements that may be individually controlled.

*Not available in 100 or 120 volts.

‹CE approved units for 220-230 volt utilize a 220 volt heating system; 230-240 CE units utilize a 240 volt heating system.

NOTE: GRAL & GRAHL Models that have multiple voltages listed, such as 120/208, 120/240 or 100/200, have multiple circuits. For example a 120/208 volt unit utilizes 120 volts for light circuit and 208 volts for the heat circuit(s). Consult Electrical Diagram supplied with the unit for specific information.

CAUTION - Strip Heaters with incandescent lights that require a circuit breaker larger than 20 amps must have a separate circuit breaker for the incandescent lights that is 20 amps or less.
