Carlin 201GAS - Manual (Page 10)

Model 201GAS burner — Instruction manual
Carlin part number MN201GAS Rev. 03/14/11
– 10 –
Where appliance instructions differ from this manual, follow the appliance instructions.
Code compliance
The burner/appliance installation must comply with codes listed on page 2 and
any other locally applicable codes.
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 errors
could result in unsafe appliance/burner operation.
Read appliance manufacturer’s instructions completely 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 8. 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 sense flame failure.)
The 60200FR control has a 3 mm flame signal test jack (item 12, page 3) 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. 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.
