LINE VOLTAGE NOW PRESENT

WARNING

4. As soon as flame is established a micro-amp reading

should be evident once proof of flame (micro-amp read-

ing) is established, the hot surface ignitor will be de-

energized.

5. The Integrated Ignition controls will have 1 to 4 micro-

amps. If the micro-amp reading is less than the mini-

mum specified, check for high resistance wiring con-

nections, sensor to burner gap, dirty flame sensor, or

poor grounding.

6. If absolutely no reading, check for continuity on all

components and if good - replace ignition control mod-

ule.

NOTE: Contaminated fuel or combustion air can create a

nearly invisible coating on the flame sensor. This coating

works as an insulator causing a loss in the flame sense

signal. If this situation occurs the flame sensor must be

cleaned with steel wool.
