I have brand new regulator when hook up to LP very little gas comes out
First, is this a regulator on a portable bottle or a regulator installed on a fixed unit. I imagine it is a portable, and that it probably has a POL safety fitting .. If that is the case, the fitting has a flow limiter that has to have a bit of back pressure. Also the valve on the tank has to have the right fitting to open all the way. Again, it requires some back pressure to fully open. You should also check the appliance tag, as some outdoor equipment requires a 15 pound regulator instead of 11 inch water column. They have a red cap or a red twist handle..
OOP! Didn't see ya there. I'm too slow.
Not really, a Guest question with all the vagueness for our magic balls.
Just too many ways to go wrong with LP installations.
I ran a warranty call one time in which my customer said his convection oven wouldn't light. After what I found and through some conversation, he'd had his plumber do the the gas connection.
His plumber had run a 3/8" copper line straight from a 100lb. LP bottle (located outside) that he'd bought at Home Depot. The copper line ran inside to his brand-spankin' new full-sized convection oven (ironically...I think it was a Baker's Pride). There was NO regulator at play there...except the 1/2 psi rated combination valve within the oven.
Based upon the temperature that day, I'd crudely calculated that there was about 120 psi of LP gas pressure going into that oven.
Some people like to live dangerously. And, the plumber was not a plumber. A true plumber would know better. Sounds like a friend or something that he is calling a plumber..
A propane gas company here installed a heater in a office conversion of a old post beam barn with 3/8 copper through the wall from a 100 gallon tank. . Building movement caused a crack in the line and eventual fire. Burned to the ground. That was about 2 years before they started requiring the stainless hook up lines.
You haven't provided enough information. Your question simply leaves too many unanswered question, such as:
I'll wait patiently for you to respond to these questions. Then we can proceed from there.
the submitter didn't indicate this was an oven installation at all... just sayin'!!!
Thanks for "sayin'!!!
The question was posted as a Bakers Pride. All the things I've ever seen of theirs were ovens. However, I looked it up and now I see that they make things OTHER than ovens.
Thanks for enlightening me.
Ecto and Fixbear, Thasnks for all the propane info. Living in a large metro area, I seldom run across propane units. In fact, the last one was for a DFG 100 that a caterer wanted converted, so he could put it in the back of his truck.
When it comes to all the all the nuances with propane, what I know, you could probably stick in your eye. Just the little you posted, expanded my knowelge base greatly.
I'm familiar with the portable operation idea. Some things to keep in mind when a customer wants to do this. He is allowed to transport a maximum of 50 lb's hazardous material without hazmat rules going into effect. Bonding, Insurance, placarding, and CDL with hazmat stamp all fall into effect. Including a special physical.annually. Add's a lot of cost. And yes, there are a lot of food trucks and potable operations that want to use 100 lb cylinders instead of 20, 30, or 40's. Even vehicle mounted tanks for RV use are under 12 gallons.
Everything in the gas industry is designed with safety as the number one function. Sometimes that does create usability problems, but safety does come in as number one. As part of this, the industry does provide free training. You just have to find it.
Lastly, Regulators are rated by BTU's. Those commonly available for domestic BBQ's and outside burners do not have the capacity for a Large commercial oven. The black ACME quick connect fitting are limited to 70,000 BTU's. Green are from 71,000 to 200,000 BTU. But you will have a hart time finding them. Add to that that sometimes tanks either get overfilled or tipped and liquid gets to the regulator causing damage or freeze up. Another problem is that the liquid can contain particulates that plug the regulator limiting orifice or valve. The newer POL hand tighten fittings have a filter just for that reason. And yes, they do plug.
Now let's explore portable tanks. A new tank was good for 15 years, It then dropped to 12 years, And is now down to 10 years. It then has to be re-certified and is good for 5 years. Problem is that to correctly re-certify one it is supposed to be hydro-ed and visually inspected. To Hydro it one has to fill it with water with no air space, place in a water filled chamber to contain it if it burst.and measure displacement. then pressurize while measuring the displacement from expansion. Each different tank has a published test pressure and displacement allowance due to different steels, thickness and shape. It then is drained and dried. Problem is, that some have moisture still in them even when new. That is why the internal visual is so important. It is also the source of particulates that give us so much regulator, fitting problems. The other source of particulates, and most common is the graphite vanes used in the transfer pumps. They wear and build up in your tanks with time. The more the tank is used, the more build-up of carbon. After all, the tank is a vaporizer. I'll give you a tank capacity chart to understand the other problem. Basically you can't legally carry enough capacity for anything commercial.
Information overload!! LOL!!
I could never get the burners to run right. Nether could our propane guy. Called Blodgett and found out that you also needed special burners for a propane conversion (who knew!) Anyway the customer bought a propane oven and scrapped the Blodgett Idea....for awhile.
I have always had trouble hitting that sweet spot with propane, where the burner looks just right and the regulator wasn't screaming. Now the only propane I deal with is in my backyard. Although, lately, I've thinking about converting an old pick up truck to propane. I have to be carefull though, my ole lady didn't like the results from my bio diesel experements. Almost burned the garage down.
Not a easy thing safe thing making bio-diesel. Heating oil, lye, and a light distillate makes very flammable vapors. Let alone the need for agitation.
Yeah, used an electric water heater for heating (no open flame) and used a bubbler with water for the washing. I think the lye was the most dangerous thing. The glycren was good for the garden but i soon ran out of places to put it. Unless you know a local soap maker, the glycren becomes a waste product that you just can't pour the closest sewer. My cost ended up being about $1.70 a gal., before having to pay the Gov. road use taxes. Since the cost of fuel has come down, it was jus not worth doing anymore.
