Welcome to Just Answer, my name is ***** ***** I will do my best to help you with your issue. First I’ll need some more info so I have a more complete picture of you situation.

I need the actual model number of your unit? It should be on the rating tag on the boiler?

Posted by JustAnswer at customer's request) Hello. I would like to request the following Expert Service(s) from you: Live Phone Call. Let me know if you need more information, or send me the service offer(s) so we can proceed.

That looks like the hot water tank rating tag not the boiler. I need to know what you have for a boiler. There is an additional charge for a phone call. If you want to talk then I'll post an additional service offer or we can continue here.

Let's continue here. What would a boiler look like? I will go in the basement.
Expert:  Rick replied 1 year ago.

The piping from that tank is connected to your boiler. The boiler is where the actual flame is that heats the water.

Ok, you have a CG series boiler. What happened when you turned the power back on? Did the boiler make any noise? If not turn the power to the boiler off wait a minute then turn it back on again and tell me what happens.

It does NOT have auto ignition . This happened last time breaker turned off for kitchen remodel.

Turning the power off shouldn't put out the pilot if it's a standing pilot. Here are instructions to relight the pilot.

Standing in front of your boiler find the squarish device that the gas piping connects to. This is the gas valve you will see a small 1/4" diameter silver tube (aluminum) connected to the gas valve. Follow this tube into the boiler to where the burners are. There should be a flame shield in your way this will need to be removed. The flame shield is just above the burners and is typically held on with a couple wing nuts. Once you remove the flame shield trace the silver tube to where it ends. What it is connected to is the pilot burner. On the gas valve there should be a dial that has indicators for ON, OFF & PILOT. The will also be an indicator (a red dot, an arrow) on the body of the gas valve right under the outer edge of the dial. The dial should be set to ON now. You need to turn the dial to pilot. Then light your match and hold it to the pilot burner. Now push down on the dial (occasionally there is a separate red button if you can't push the dial down) this will allow the gas to flow to the pilot burner. Once it's lit you need to hold the dial down for 60 to 90 seconds then you can let the dial back up. The pilot should stay lit. Now put your flame shield back and the dial to ON. At no time should you force the dial.

If the pilot doesn't stay lit when you release the dial/button then you probably need to replace the thermocouple. Probably not a DIY project.

I have to leave for a while. I'll respond when I get back if you have more questions.

I'll send you pic of that box. Not as u described.
Expert:  Rick replied 1 year ago.

That's the transformer not the gas valve. There's no gas pipe connected to it. You have to remove the front panel to get to the gas valve
