 For starters, I think the orifices have to be different. I can't remember how it goes, but the openings are larger for one type (NG?) and smaller on the other (LP?) due to differences in pressure. I don't see why it couldn't be adapted for NG. GE made literally tons of dryers designed for NG hook-ups.
Maybe there's some GE literature in Ephemera that speaks to this. | ||

The dryer is already converted to propane, I wanted to change it back to NG. Unfortunately after doing an internet search the correct orifice valve seems to be NLA everywhere, crap.. | ||

In my area propane companies are next to useless, they deliver propane and thats about it. I wonder if the orifice is a standard size that may accept a substitute? | ||

worst case scenario.....you have to buy a whole new gas valve, their usually already setup for NG......
and for the most part these are usually standard valves and fittings....you could almost interchange between models..... can't believe you could not find one....I was able to change mine back, and mine is a 1985 unit....got the kit off ebay... | ||

Thanks for the info. It is a standard older 70's GE dryer with the D shaped opening and 22,000 BTU burner. | ||

Looks like .. a number 42 orifice will do just fine. | ||

Brass and Aluminum
For a dry application it is unlikely you will ever see any problems mixing fittings of these metals. Brass and aluminum aren't that far apart on the Anodic index so as long as you aren't dealing with a wet, or corrosive environment you should be fine.
For safety and ease of future disassembly consider using a something to protect the thread interface. A good pipe thread compound (I like Locktite 565) or Teflon tape would work well if you are dealing with tapered pipe threads. If they are just straight threads,which have less clearance, I'd use a smear of silicone grease. Just filling the threads so that air and moisture is excluded will do the trick. I have come to use some silicone grease on most every threaded plumbing fitting (non pipe thread) that I work on. Years later they unscrew with no drama at all! | ||

Right, the cap has a gasket and should be only moderately tight as I understand. | ||

never had to adjust the air mix.....as long as its a blue flame, with some yellow tips, your good to go......give it a few cycles on/off before you decide it needs adjustment.....and you can adjust while in operation, probably best this way you can adjust small increments at a time....
I have seen a 50/50 yellow/blue at the start, and then taper to the 90% blue....even if an adjustment is needed, keep an eye on it for a while.....once set, your good to go.... happy drying! | ||

Pressure Regulator Caps on Gas Dryers The cap for Natural Gas is called a leak limiter because it has a very small hole drilled through it, this is necessary so the diafram in the pressure regulator can flex and work [ the back side must be at atmospheric pressure ]. The very small hole in the cap will allow a very small amount of gas to leak if the regular diafram leaks, but this would be too little gas to ever cause a fire or explosion. Generally the main burner air-shutter needs to be open completely for either nat or LP gas. There is a BIG difference between orange flame and yellowish flame, orange is caused by dust and dirt being burned, yellow flame on the tips is usually caused by too little primary air [ air shutter adjustment ]. If you know what you are looking at there is no need to wait for several burner cycles, the air shutter adjustment can be made immediately. | ||
