I have a customer with a cc150. 2 months old. Ran good for about 3 weeks. Now it won’t recycle and locks out with a 4E code - means flame failure or loss of signal. Found a cut in the ignition cable. Thought “ha this is the problem” NO. Still acting up. Spoke w factory re this. Natural gas fired. 9” inlet. Drops to 6.9”WC on forced high fire. Clocked the meter to 132,061btu. Adjusted mixture w analyzer to midpoint factory settings 45 ppm CO. Book says <100ppm. Unit fires drops flame does this twice and on the third time seems to ramp down and stay rectified. Runs for 3 hrs or so then locks out.
