    Not sure I understand the issue. There is no “gas/ valve” on a boiler. You have a gas valve and a water pump? Is the boiler running?
    In other news, you may have the last HeatMaker left in operation. It would be a good idea to start planning its replacement.

    They liked to eat pumps, high temps on water for these internally 200 or so. Tended some times to trip thermal overload of pump. Usually was a 1542 grundfos if memory serves me. Not sure what has happened at this juncture. I still have some parts if you find out there is a bad part. Was not a big fan but still had to service some. Not fun.

    There was an installer here in the Bay Area who loved them and installed many. He left town and told everyone to call me when they needed service. Mercifully, they've all been replaced as they were not easy to work on.
