How to add leak sealer?

Wolverien2005

I know I have to replace it but moved into a house not even 6 months ago and boiler started leaking recenlt. So doing this as a temporary fix. I will buy a leak sealer from home depot. Where do I put it in? I looked around the web. Picture of my boiler


I have this boiler http://www.peerlessboilers.com/Products/ResidentialBoilers/SeriesWVDV/tabid/117/Default.aspx#dnn_relateddocuments
The instruction says pour it through safely bulb .Any help is appreciated. Sorry for the noob question.

I feel for ya, but what you're planning is bad idea.

There's no such thing as a mechanic in a can.

Don't. Fix the leak or replace the boiler if that's what it takes. The sealer, if it works at all, may seal up the leak -- and get gunked up into a lot of other places which may or may not be repairable.

Just don't do it.

Okay thank you both for reply. I will think about it.

Where is the leak? If it's in a return pipe, it will be repairable.
The safety bulb is the pressure relief valve, (PRV).--NBC

Also, if you have a tankless coil, the boiler seal will adhere to the exchanger and you'll lose hot water.
It's getting warm. You've got some time to research equipment and contractors.

Is this a steam or hot-water system?
