Baseboard boiler pressure near zero; How to add water?
Hi,
I am having problem with my baseboard heating system. The problem started with intermittent noise about 2-3 minutes between, then I also noticed there is no heat in first floor and second floor ( the boiler is in the basement). The gauge displayed the temperature about 220F and water pressure between 0-5 PSI. By reading postings on this forum I believe the water needs to be filled, but I don't know how to do it on my specific system. The following is some of the photos I took. Many thanks.

Low water
Shut the boiler off NOW. You risk serious damage if you introduce cold water to a boiler that hot.
If you posted your photos on photobucket or similar photo sharing site, there should be instructions on that site on how to link to that site. If you can't find them, you can just copy & paste the url of each photo to your reply here.

Grady,
I shut off the boiler last night and now the temp on the boiler gauge is below 70F. Also I have added the photos to the previous post.

Sorry for the slow reply. Busy day & evening.
In your second photo there is a brass device with a blue handled valve on each side. Make sure both valves are open. Once they are, the brass device with the handle on it,(pressure reducing valve) should feed water into the boiler to about 12 psi. If it does not, lift the handle but watch the pressure carefully so it does not exceed 20#. This handle is a "fast feed" & by passes the pressure regulating feature of the reducing valve. Once you get to around 12-15# with the handle lifted, flip the handle back down. If the pressure continues to rise, shut off the blue valves.

Thanks Grady for the tip, actually that's what I figured out yesterday, and the pressure is about 17 now.
