Found primary control in a hard lockout. Homeowner did try resetting a couple times. Outside Tank is less than a quarter full. Tank is in bad shape. I told Alex to remove snow from under tank. Reset primary control out of hard lockout and with bleed through wrench I bled oil line.

He said soonest he can get oil delivered is Monday. I told him he can get diesel but that he may need to bleed oil line again. He may also need to bleed oil line when oil is delivered on Monday. I walked him through how to do it exactly. He’s gonna get a 3/8” combination wrench and 10 gallons diesel.

Commercial steam boiler Weil McClain Model 588 (845,000 Net AHRI output) installed a couple years ago will randomly cut off on flame sense failure. They have had to reset burner control from this since the boiler was installed. “Fire eye uM” flame sense control. The UV flame sensor for this boiler is part no, UV1A6. Took it off and inspected it. it did have some dirt on the eye which I cleaned off with clean towel. The boiler did not go off on flame failure while I was here. Boiler cycled on and off several times. The other issue they said they were having is the make up water tank they had to open the feed valve to the bottom of the tank.

I arrived to the customers house for no on a newly installed oil burner furnace was in March 2025. I did find that customer was getting low on fuel. He has a refill on February 1. I looked inside the tank. He does have enough fuel at this time, but the real issue was wasn’t getting through and out of the nozzle. I did check my oil, flow oil filter and strainer. I had good flow coming from the pump. I removed my nozzle gun and my nozzle and electrodes had solid carbon on it and in the blast tube. This would prevent the furnace from firing off. I went through the system and replaced the nozzle .50x80A and cleaned the electrodes, and cleared the nozzle gun with cleaner and a piece of wire. I set my nozzle assembly with my z gauge and adjusted my pump pressure was at 130 set back to 120 psi from system specs. No charge for today’s service warranty. Customer is aware that if it does run out or it gets air locked from the fill it can be chargeable for to bleed and prime.
