lubu726 Member Posts: 3
I have an old hydro therm boiler that having trouble where the flame keep cycle off after couple mins. Im clueless when it come to these so i look at a youtube vid where they said to bleed the air out so I did that. But even after that done, the boiler still have the same issue.

If anyone know what might the problem or give any tips thank you

    Without a lot more info on the system and the symptoms, the only tip I personally can give is stay off YouTube and get a heating pro.
    If you're not experienced with gas, things can go boom.

    How many hydrotherm boilers are there? Most have a Honeywell aquastat on them. Pull the covers the aqua stats and check to see if ther is a small white dial that would be your differential for your burner set it to 10-15 it’s probably set at 5f. Also are you usng the hydrotherm out door reset panel?

    Is the pump running? Are the rads hot. Is the boiler piping to hot to hold?
