measuring propane pressure

[emanon25]

i've been having various problems with propane powered devices. i recently installed a new marshall mod. 250 regulator and then after reading posts here learned that they may have frequent quality control problems. i decided i needed to measure the actual pressure at an appliance. to do this i built a monometer using suggestions found here and on the net. the manometer is built form a 1x4, 3/8" inside diameter plastic tube, nylon cable ties and filled with my left over coffee for easy visability.

i found that the regulator was shipped with the pressure set far below the required 11 - 14 inchess required by the propane appliances. before using the manometer i had already adjust the pressure by tightening the regulator 4 turns just to keep my pilot lights running longer.

i found my presure was just under 11 inches with no load and fell to about 10 inches with three stove burners operating. i adjusted the regulator to provide about 13 inches with no load. it fnow alls to aproximately 12 inches with the water heater operating.

i'm hoping i'll see some improvement in the marginal operation of the refer and water heater pilot.

Thanks for the demonstration. The courtesy of your post and documentation is appreciated. It certainly will be helpful for me getting the system dialed in.

good luck with your system. i think a big problem with a.s. gas appliances is that the propane is plumbed with copper pipe. we quit using copper for gas in homes many years ago because the sulpher dioxide that is added so that gas will have an odor, reacts with copper and causes small orifices to be blocked by particles. it would probably be a good idea to replace all the copper gas pipe with aluminum.
