Went on peerless site couldn't find your model even in the discontinued boilers. Take a couple of pictures of the burners, gas valve and controls.

These help?

Here's the data plate and original diagram I can't make out

Any numbers on the existing components? Gas valve, aquastat? What ever else is in the system?

It all looks like Honeywell parts and each individual part can be looked up and wiring diagrams should be available.

If nothing else, call Peerless, or whom ever owns them!

Room thermostat goes straight to the gas valve two wires 24vac. 120vac goes through limit switch Which in the bottom klixon 2 nd pic.
The top pic is the fan control diagram calls it( reactor two smaller push on terminals)
Limit looks like the bottom klixon
Diagram looks wrong
Limit 120vac to ground
0 vac across terminals
should have 120&24vac across transformer

I believe I got what your talking about. Also my limit and/or fan control one of the 2 has a temp setting with a flay rip screwdriver. Which is that...

Do you have power on the valve? Transformer?
