Andrew was here to clean our furnace today, and as always did a fantastic job. He found a few minor things that needed replacing and showed me the parts. Also, after 30 years of boiling hot water, he said our mixing valve needed replacing, must of asked a dozen plumbers and furnace people over the years with no results. These people are the real deal, so happy we have them!
Excellent service, thank you Larry!

When the power for the boiler is turned on, the controls just click. Checked the aquastat and the option controller. The aquastat is showing a code of 15, waiting for limit to close and the option board was showing error 5. Error 5 is a power issue to the board. Checked voltage, 119 volts. Called Burnham tech support, they said with the error 5, the option board is bad and needs to be replaced. Jumped out one plug which sends power to the aquastat, and the burner starts properly until the board is replaced.
