Hello -

I have an old american standard hot water natural gas boiler and it just stopped firing up. Pilot lights are on - Bosco switch is open/on. Transformers are all showing 25-27v. Only thing I can think of not working is the Old Detroit Lubricator Company Gas valve not working - any way to test or clean it or can a new-old stock from 1950 somewhere?

Attached a few pics - Hopefully someone has an idea.

Did you change the double AA batteries, they are probably dead.
Double AA? Is that equivalent to a single B cell?

Since you're canadian dont you guys use Double EH cells?

I prefer Hershey’s over Bosco
