New Marshall Regulator not delivering the gas like the old Fisher

[Lothlorian]

I developed a gas leak in my old Fisher (1973 ) regulator so I figured it was time for a new one. I read many threads on this forum and finally decided on a Marshall. All the RV dealers I called around this area sell Marshall.

I installed the new regulator and nothing leaked. I did here a hissing sound coming out of the screen port on the bottom, but I did not smell any gas. I used the soap and water around all the fittings and did not get any bubbles. I tried the burners and they worked but I did not get the flame like I did before. The flames look like I have it on low.

Should I be getting flames like that or is there something wrong with this new LP regulator. It is a Marshall dual atomatic change over regulator.

I bringing this back to the portal page to see if I can get any information.

Found a great article on what might be my problem. As soon as it is light out I will try to shut all valves in the main line down. The article says the ODP valves will not give you a good flow of gas if you have a leak somewhere. They were designed to hold the gas if there is not any pressure in the line. I will close off the different valves to all the appliances and see if I get the back pressure I will need.

All my posts. My theme is out with the old in with the new. I decided to take every thing off the new Marshall and replace all the old fittings with new fittings and one corrigated original gas line which I kept with a new corrigated gas line. I used yellow teflon tape on everything. I hooked up the new gas lines to new fittings and everything is working great. I used soapy water on the new fittings to make sure there were no leaks.

When I took off the old corrigated gas line I found a hair line crack in the middle. I think that is what was causing the pressure lost. I tested the burners and they never have worked better.

Glad to hear you fixed the problem. I need a new regulator and I am planning on buying a Marshall.

Brian,

Those flexible lines are supposed to be replaced every time you get a new appliance and I guess a regulator counts as an appliance. I have wondered whether that recommendation is just to sell more of them, but in your case anyway, it was a good idea.

Good
