11/11/25 Tan Performed quality assurance visit on newly installed gas boiler converted from oil. Client has no complaints and thought our team did a great job. While system heats home comfortably, he stated two of his radiators don’t seem to be working. We later found that the valve for the one was not open and it had some air in it. He will test the other one and let our installers know if there’s an issue when we return to take out the oil tank. Started boiler operations. Confirmed pressures were accurate on the gauge. Piping is superb with circulator piped on supply after air eliminator that is tied into expansion tank and the water feed at the point of no pressure change. Pipes returned hot as they should. Checked combustion and found it very good. Draft and smoke test confirmed clean combustion. System settings were good as well. Visually inspected oil tank with install manager on phone and decided that we will pump from the outside with a 50ft hose that should reach. Tank sits

Inspect low and high voltage connections and components, replace oil filter nozzle and pump strainer. Check oil flow ok test boiler operation performed combustion test and smoke test ok.

Fire block chamber inside burner is in bad shape major cracks. Showed customer boiler condition. Current oil boiler does not have water feeder. Would recommend getting an estimate to replace boiler.

Hi velocity system good install with a mitigation board just for further reference the wiring for mitigation board in the instructions is not correct. Supply temp 50° system running to manufacture specifications.

Spoke with Bob on arrival who indicated unit was not keeping up consistently on hot days and temperature would climb during the day until is was up in the 80s. Walked the home, the unit installed is for the 2nd floor only. Reviewed installation and inspected ductwork for leakage. Old ducts are not sealed, it is recommended to seal ductwork but this is not related to problem. Inspected wiring and found unit wired as 2 stage and outdoor unit is a single stage unit. Rewired to jump Y1 and Y2 together as recommended in installation manual. Checked dipswitches to ensure airflow is setup properly, set to 390 cfm/ton and set to 2 ton. There was no signs of condensation in pan or around drain line but trap is not insulated. Turned system on and checked system charge and delta across coil. Superheat at 18 degf and subcooling at 8 degf and delta T at 18 degf. System is working properly at this time. It was 75 degf outside so there were no signs of a problem. Instructed Bob to call me
