Brushed and vacuumed flue pipe and heat exchanger Replaced oil filter, nozzle, and strainer Checked all electrical connections and safeties Performed combustion and smoke tests 7.4%o2 2ppm co 0 smoke While performing the maintenance we found the combustion chamber is starting to crack and show signs of wear. Recommend replacing in the future. Also saw a hi-vent above the boiler had been leaking in the past but had sealed itself shut again. While bleeding the oil line before testing the boiler we noticed the oil pump solenoid valve was starting to leak oil. The overhead oil line could be the cause of it leaking due to the oil pump having to work harder with an overhead oil line and with pockets of air causing the seal to start to dry out. Recommend installing a tiger loop to lessen the stress on the oil pump and burner motor. After getting customer authorization we replaced the oil pump. Started and tested it and dialed in the fuel pump pressure. Unit is working properly

Checked system, and the circulator was very hot. Turn system off to check if the system was air bound or if the circulator was bad. While adding water to purge, notice water on the floor. Water was coming from the bottom of the boiler. Looked inside the chamber and between sections 2 & 3, water was coming out and filling the chamber. Turned water off and disabled the circulator and burner. The boiler needs to be replaced. The office will work up a price and get back to the customer.

Replaced the pressure relief valve and filled the system. Noticed the hi-vent also leaking and replaced. Purged the 2 zones. Started the pilot flame and turned the switch on for the boiler. Checked the circulation of the water. The autofeed is leaking by, shut the incoming water valve off. The packing nut for the autofeed isolation valve was leaking. Tightened the nut. If the valve continues to leak, recommend replacing the valve and the autofeed.

When arrived, the pressure relief valve was leaking. The pressure was at 20 psi. Tapped on the extrol tank and it sounded empty. Replaced the pressure relief valve and purged the air from the system. After purging and checking the system, the pressure was still increasing. Isolated the auto feed to make sure it wasn’t leaking by. Auto feed is good. Isolated the domestic side of the indirect and the domestic is not leaking by. Purge the system again and the is no air but the pressure keeps increasing. Replaced the extrol tank and the pressure stabilized at 20 psi with no more issues.

Remove and install a new wire harness inside the Mitsubishi Evap Unit. Also, we will go into the attic and reconnect the wires inside the branch box. Start and test the system. The bedroom unit starts properly, 53* discharge. The louvres are not moving up and down like they should. The motor and/ or lower board may need to be replaced. The customer does not want to do those at this time Checked the boiler. The extrol tank is ok. Replaced the pressure relief valve and purged the system. There was a little air in the system which can increase the pressure in the boiler high enough for the pressure relief to start dripping.
