Where appliance instructions differ from this manual, follow the appliance instructions.
3. Wire burner
General wiring requirements
Read and follow the guidelines below. Failure
to comply could result in severe personal injury,
death or substantial property damage.
Electrical shock hazard — Disconnect electrical
supply to the burner before attempting to service.
Electrically ground burner — The burner must be
grounded in accordance with local codes or, in the
absence of local codes, with the National Electrical
Code, ANSI/NFPA 70, or
CSA C22.1/CSA C22.2
Canadian Electrical Code for Canadian installs .
Label all wires before removing for servicing. Wiring er-
rors could result in unsafe appliance/burner operation.
Read appliance manufacturer’s instructions com-
pletely before wiring burner.
The 60200FR control requires a constant 120
vac
power source from the appliance as well as power
from the appliance limit circuit. See Figure 11.
Check polarity carefully. If hot and neutral wires are
reversed at appliance power source, the control will
lockout on flame failure.
If replacing any of the wire supplied with the burner,
use minimum #18 AWG 125°C or better.

Verify power supply
1. The burner requires a 120
vac
/60
hz
/single-phase power supply, with at least a 10-amp
fuse. The current draw will be (when equipped with typical motor and Carlin 41800
electronic ignitor) approximately:
2. The 120
vac
power connections to the black and red/white wires of the 60200FR
must be the same polarity from the same power source. DO NOT attempt to supply
separate power sources. Check the power from the appliance with a voltmeter. Verify
that the supply to the black and red/white wires are from the 120
vac
HOT side and
that the power is no less than 102
vac
nor more than 132
vac
.
Checking burner flame signal
The 60200FR uses flame rectification to detect the flame. Because the grounded metal
surface area near the flame rod is much larger than the surface of the flame rod, current
flows through the flame more easily in one direction than the other. This causes an AC
voltage applied to the flame rod to result in a DC current. (Note that, if the flame rod should
touch a grounded metal part, the current would be AC, not DC, and the control would not
sense flame causing a flame failure.)
The 60200FR control has a 3 mm flame signal test jack (next to the terminal block) that
can be used with a flame signal meter, such as the Honeywell W136. Or you can use a
standard 3 mm stereo plug fitted with two leads (Carlin part number 99017). Connect these
leads in series with your ammeter leads to read DC microamps.
The minimum flame signal needed to satisfy the 60200FR sensing circuit is 0.8 microamps.
The control will register flame failure at any lower signal.
