WIRING

The appliance, when installed, must be electrically grounded in accordance with local codes or, in the absence of local codes, with the National Electrical Code, ANSI/NFPA 70 or Canadian Electri- cal Code, CSA C22.1, if an external electrical source is utilized.

This appliance is equipped with a three-prong [grounding] plug for your protection against shock hazard and should be plugged directly into a properly grounded three-prong recep- tacle. Do not cut or remove the grounding prong from this plug. For an ungrounded receptacle, an adapter, which has two prongs and a wire for grounding, can be purchased, plugged into the ungrounded receptacle and its wire connected to the recep- tacle mounting screw. With this wire completing the ground, the appliance cord plug can be plugged into the adapter and be electri- cally grounded.

CAUTION: Label all wires prior to disconnection when ser- vicing controls. Wiring errors can cause improper and dan- gerous operation. Verify proper operation after servicing.

Note: For testing flame sensor circuit use a micro-amp meter in series with sensor. Minimum current should be 1 micro-amp dur- ing operation. Be careful as flame sensor is in the 115VAC circuit. If current is below 1 micro-amp, remove sensor, clean with light sandpaper and retest.

Note: This heater is equipped with a remote bulb electronic thermistor control located low on the back of the furnace. Sometimes due to field locations different air currents may ef- fect the control sensing of the thermistor. This sensing bulb can be re-located if necessary to provide for better air sensing and control.
