Thread: sealant for natural gas

Tweet

Broke down and got me a new heater today. Reading through the directions on sealing the natural gas supply line it states, "sealant, resistant to natural gas and propane/LP gas."

Is there some special sort of pipe dope for gas lines or something?? I've always just used the teflon tape or regular pipe dope??????

Nope that I know of.We have sold a whole bunch of the vent free heaters too where people just used the pipe dope and soapy water to check for bubbles for leaks.If there is a product out there,let us know.

Rectorseal -available at any hardware or plumbing store.. Best stuff ever for water, gas, air and petroleum products..

Thanks Glenn, I'll get some in the morning!

I checked the install date on my old shop furnace, it was installed in 1996 so I guess it had a good run considering the somewhat less then perfectenvironment it lived in!!!! Lots of dust, overspray, heck, you name it and that poor thing had to endure it!!!! Anyway, got the exhaust fan replaced and it worked fine for about 3 heat cycles, then quit and flashed a code for a pressure switch open. Got that working and it flashed another code for the high limit cutout closed, and on and on and on with different codes. We determined it must be the board with all the little electronic gizmos on it. I called the place I got the motor from and they said it would take a couple weeks to get it, cause the unit itself was old and discontinued, and it was going to cost $350.00----at which point I said thanks but no thanks and went shopping!!!!!

So, after a bunch of studying and phone calls to tech lines I got a wall mount radiant heat unit this time. I had ceiling mounted radiant heat in the big shop and really liked it! My ceiling is too low in the garage to put one of the tubes in, so I went with a wall mount that has a small fan with it to add just a bit of circulation. I also have a fan in the shop that circulates the air quite well.

I wanted to try something new. My old Reznor did an acceptable job for 16 years but I just never did like all the fan noise, plus it seemed every time I was working in front of it, the heat would come on then all that hot air blowing on me... Guess I was just ready for a change! The old unit was 25,000 BTU, and this one is 30,000 BTU so it should do fine. Recovery time is slower with radiant, but it's not very often that the big door is opened and closed anyway.

I'm really anxious to get it installed tomorrow and return my borrowed electric unit and get back to work! Amazing how something as simple as heating a shop can cause so much disruption and lost time when it breaks! Just another one of those things I probably take a bit too much for granted!!!!!!

Dave some of those you can buy as a accessory a fan to install.Really simple to do.

The new heater sounds like it should work great, Dave. It may have a bit longer recovery time, but you also boosted the capacity a bit and the radiant will "feel" warmer, too. Sounds like you've got the air circulation covered too - any more might be blowing your hair as you work

Yeah Roger, it's good in theory anyway. Have to get things installed and see if the practical application is as good!!!! As for the hair blowing in the wind, guess I'll just reserve that for scooterin' days!!!!

Home Depot or Lowes has a teflon tape to seal the threads on gas line. It is YELLOW in color and appears to be a little thicker. In the water heater gas appliance hook up section.
