Empire Comfort Systems PV-28SV50-B2H(N,P)-1, PV-28SV50-B(N,P)-1 Wiring Diagram

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.

WARNING: Potential risk of fire, electric shock, and personal injury. Take precautions to reduce such risks.

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.
