Relay coil burning out

I suppose that if they just put the voltage on it would be fair to assume that AC or DC didn't matter ;-)

That's what I thought when I used the relays (which I happened to have). The other relays in the main panel are OK, but they don't operate in a 'pulled in' mode 24/7, but this one has a safety relay function, if the gas fails or the electricity goes and the furnace drops below 800C then the air blower won't come back on and air pressure operates the gas solenoid. Above 800C the furnace will relight itself OK when the electricity supply comes back on, but then it will only operate in a low fire mode (reaching about 1000C) until manually reset to full operation, when it will go to the set temperature, normally 1250C.

The relay states 24V AC on the picture. Thinking about it 24V AC will be RMS so the peak with be higher about 34V !!

Yes, indeed it will and you will then have AC running through an inductance, which should tell you something, if it doesn't then at least it tells you why AC or DC is included in component marking and should be observed ;-)
