Job Checkin

Performed preventative maintenance for a crown boiler, model #Awi128enst1psu serial #Crownb000461218. Upon arrival the system was calling for heat. I powered the system down and removed the access panels. Removed and cleaned out the burners and burner box. Water pressure is at 20 psi and the limit is set for 180°. Checked all electrical connections to ensure that they are secure and in good condition. Checked all copper piping for signs of corrosion and leaks. Powered the system back up and called for heat I observed the system starting normally and took a combustion analysis test I received the following readings O2 is 13.2% and CO is 5ppm. I observed the system running until it reached the water temperature limit. The burners went out and the circulator pumps continued pumping water, this is normal operation. The system is operating properly at this time.
