propane question

Techman

I think you should let the propane co. come in and test the gas pressure with ALL appliances running.Possibly have the heating co.test each units manifold pressure,and also the oven repair co. check the ovens at the same if possible .Or does the gas co. do all of the above?

PROPANE QUESTION

I have a Church as a customer who is having some problems with their propane equipment and I was looking for some input here. This started when one of their Rheem units would not fire up correctly. It has eight burners, and most of the time when they turn the heat up for service, only a couple of the burners fire and the unit shuts down, tries again, and sometimes it lights, sometimes they need to turn it off and reset it for it to work properly. I've checked gas pressure,it's OK, removed and cleaned a small amount of dirt from the gas piping, gas valve, burner and orifice assembly per the Rheem tech rep's instructions, and the problem continues. Now the second unit is doing the same thing. In addition, there is a commercial size range in the kitchen, and the first outlet on that unit is an oven, then 8 burners, then a second oven all piped from a manifold. The first oven, when the gas is turned on, gets wet with condensate. Does this sound like a gas supply issue to you? The Pastor is calling the propane company to get their input. I thought I'd see what the folks on The Wall thought.

Check the outside regulator. They get cold and old.

Not lighting all the way across?

I've had that problem with a number of Rheem/Ruud/Conquest etc etc. Many times I've found that despite cleaning the burners and making sure gas pressure is correct, the only fix is to replace the burner set. Seems like they just get worn or burned to a point where they will no longer provide proper gas flow through the "wings" enabling the next burner to light off.

That being said, I'd double check the clean part of the problem, then hook up a U-tube liquid manometer and watch it when the valve opens. See if it drops or bounces the liquid. Digital manometers sometimes aren't fast enough to catch a momentary drop in pressure. If your pressure drops much at all you have a regulator that's not reacting quick enough or a gas line sizing issue. I don't like to see much more than a 1w.c." drop when the valve snaps open. Check it both upstream and downstream of the valve.e
