What is the brand and model of the unit you're trying to light?
What model? are you looking at the indicators on the gas control valve at the boiler?
I'm sorry but your description doesn't add up for me. Can you post a picture of the gas control valve and the boiler here? you can post pics here by clicking on ADD FILES next to the send button
Sorry for the delay. Thanks for the pic but I need a wider shot and a shot of the boiler
I'm sorry but your gas valve pics are not helping. Please give me a wider shot this time show me the entire inside of the burner compartment including the gas valve.
Ok, as I suspected this is a pretty old boiler. We need to do some trouble shooting which will require jumping some electrical connections. Are you OK with that?
You can run it on manual but keep an eye on the pressure gauge. If the pressure gets above 5 you should shut it down until the pressure drops then put it on manual again. If you just leave it on manual the pressure could get dangerously high. The relief valve should blow at 15 psi but as old as it is it may not work. You really need to call in a plumber but you can run it on manual under the above conditions
