I'm currently waiting on a plumber for the next week or so. It's the first time I've turned the system on this year. It's a Natural gas system, single zone with a mechanical thermostat.
- I have visually confirmed that the pilot is on.
- I changed the thermostat and cranked it up to 85 and I hear the click
- Boiler doesn't seem to be kicking on.
- Wiring seems to be okay
Anything I should check in the mean time while waiting on the plumber?

You have a nice simple system -- it appears that about all there is is a thermostat, a boiler, and a circulating pump. If that is so, it would be helpful to know if the thermostat controls the boiler directly, or if it turns on the circulating pump -- or both.
Do you hear a click at the thermostat, or down near the boiler when someone else turns up the thermostat?
Does anything happen at all near the boiler -- pump turns on, for instance -- when you turn up the thermostat?Br. Jamie, osb

I haven’t checked if there is a click at the boiler end. I can check then. Here is a picture with the door off.

If you have only red and white at the tstat, jumper those together....only those two.
See what happens.
Show a picture of the old tstat, front with cover off and back.
Also the other side of the boiler.0 -
The old thermostat is exactly the same. I just changed the cover, I didn't bother taking off the wires to replace. Will try to get a picture of the other side of the boiler later.0
