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.
