Upon arrival I performed a tuneup and safety inspection of the Knight KBN106 boiler. During my inspection I discovered that there was a fault in the combustion and ignition safety system. I presented the concern to the customer and the customer chose the band aid HM2A combustion and ignition safety system rejuvenation option. Also, performed a combustion analysis and combustion readings are within normal range. After making the repair the boiler system is operating within the manufacturers specifications. Thank you
Upon arrival the customer informed me that the Lochinvar boiler system wasnâ€™t operating and the displayed fault code was failed ignition. The customer also informed me that they had refilled their propane tank a couple of weeks ago. When I first ran a trial for ignition the boiler wouldnâ€™t operate. I verified that the gas valve was being energized which it was. I knew we were getting spark ignition but there was no combustion so I continued to troubleshoot the gas line. I verified that the inlet gas pressure was within the manufacturers tolerances and which I found the pressures while idle and while operating to be within the manufacturers tolerances. I was able to check gas pressure while in operation because after several attempts the boiler system began operating. I then called Lochinvar technical support as I was hearing a fluttering sound during ignition. I was instructed to adjust the outlet gas pressure because the fluttering meant a lean fuel mixture. I adjusted the outlet

Replaced bad board on Goodman indoor furnace for office space. M# AMH80704BNAB S# 0704056630. Replaced both thermostats in office space per customer request. Checked operations on both systems and they are heating as designed.
Upon arrival the customer informed me that the boiler system wasnâ€™t operating and it had a displayed fault code of failed ignition. I removed the burner assembly and cleaned the flame sensor and electronic spark ignitor. After putting the burner assembly back together, the system then produced a fault code of fan speed which the description states the fan is operating at 30% less rpm then what it is being called for. I again removed the burner assembly and inducer to find no problems. I put everything back together again and the system operated immediately. I believe I didnâ€™t have the electrical connector in all the way which produced the fan fault. I cycled the system multiple times and the system operated each time without faults. I concluded that there must have been just enough carbon buildup on the electronic spark ignitor or possibly there was a restriction in the propane line that was knocked loose during removing and re-installing the burner assembly. I recorded 11.2â€ WC
