flexible gas line

[Mike Honcho]

Is flexible gas line the type for dryers and ranges, ok for hanging heaters? I am ready to finish my big maxx and was unsure if this was code or not. Thanks.

If you mean the yellow coated flex line, yes. Make sure your get the proper diameter.

Yes, this is what I'm looking at except 24 inches, good for 85k btu

Yep, just for the last short distance to the heater.

Be sure to design in a DRIP LEG in your gas line to capture any moisture or debris that might be in the line.

The old drip leg. I think its a racket conceived by fitting and ****** manufacturers. Although I have to install them per code, I don't put them in my personal stuff, its just a waste. For years we didn't have them and we NEVER had an issue because of it.

^ ^ ^ You may have consistently DRY natural gas in your area.

Generally your comment is true that drip leg is not all that necessary. However, it IS the last chance safety factor to catch any debris or moisture that is in NG supply line.

However, SOME locations had consistently WET natural gas provided by the monopoly NG supplier. For these a drip leg IS REQUIRED. In Ohio there is CNG enthusiast with own home NG compressor to fuel his vehicles. There was so much moisture in the NG that problematic quantities were accumulating in his CNG tank of car. Solution was install in-line desiccant dryer so that moisture was eliminated before it ever got to NG compressor.

Thanks guys, yes i have a drip leg at the heater. Just need to go from the wall to the heater and wire it up.

Agree except for the "monopoly" NG Supplier. Your local distribution company is buying their gas from an intrastate pipeline who is ALLOWING liquids into their line and telling your LDC to pound sand when they complain about it. My point being...liquids cause no end of problems to local gas distribution companies (including the occasional irate customer) but they have no control over what their supplier allows to go in their pipeline.

The shale plays are making the situation worse, as many are very high in liquids. Ohio is sort of at the epicenter of all of this too. So...you may be seeing things the rest of us won't see for a couple of more years.

^ ^ ^ Yep, the "monopoly" is somewhat at mercy of "pipeline quality" NG that is supposedly entering the pipeline. My CNG friend in Ohio might be located in such a place that he's getting wet gas before monopoly NG provider can run the NG supply through their drying station.

In general, there is need for more pipeline infrastructure, and some circumstances drying stations so that true pipeline quality NG (ie dry) is delivered to the end customer.

I just hope & pray that we'll actually USE our own abundant low cost NG here in USA, rather than ship it off to China as LNG. We really SHOULD be adding NG infrastructure at record clip and putting 1M more NG vehicles onto road annually, instead of snail's pace we're at now.
