Pressure regulators

Do gas regulators have screens that could become blocked up?

    Regulators have screens

    on the vents of house regulators to keep insects out. Most applince regulators ahve no screens. Some gas valves have screens to keep dust and rust from entering the valve and contaminating the seat of the valve.

    pressure regs.

    Sounds like you can not get gas paul. I have seem the screen for the regulator blocked at the meter. I disconnected the meter from the house pipe and was suprized to find no gas so yes it happens. That was about 10 pm on cold night after I changed the gas control in the furnace and the flame was really low then it went out.

    Regulators

    Thanks for your replies, Tim and Jim. The problem is on a job with propane. Started the boiler up on Friday and things were fine until noon Saturday. It's a new system. Maybe some dirt was left in the tubing that the propane company ran. The regulator is on the outside of the building on the wall behind the boiler and I was thinking it might have picked up some crud.

    Propane is another story

    if it is a new job then what you are saying is that the second stage regulator is giving you a problem. Was the propane treated with Methanol when the tank was filled? If not moisture can be a problem with new tanks. What is your gas pressure after the regulator? It should be about 11" W.C.. What kind of temperatures are you experiencing in your area as temperature drops tank pressure from the tanks first stage regulator to second stage regulator can drop considerably.

    Regulator

    I'm guessing the second stage regulator is the problem. Don't know about the methanol. We had about 11" plus when we started the system up. Temps have been fairly steady between high 30's and high 40's.

    Tank

    The tank was at 70%. They placed a temporary one until they can get out on Monday to fill the main tank.

    I bet that

    temporary tank does not have methanol and that is your problem. If it has moisture in the tank it will really mess up the lines.

    I would make sure when they fill the main tank they inject some into the existing lines.

    Thanks

    I'll be there tomorrow when they come to fill the main tank and find out if they have used the methanol. Is the use of methanol a standard practice?

    Paul I think Tim and D are on the right path you may have moisture in the tank or line, it only takes a drop of water to screw things up. you have an above ground tank (a loaner for now) with morning temps at 30 degrees that drop of water has turned to ice in the needle size hole of your regulator. Want the country solution Paul dump a bucket of hot water on your regulator and see if you don't get gas if so add methanol to the tank to dry the gas if no gas change the regulator. best of luck

    good also on a frozen regulator.
