Wall Furnace Pilot Burner Tube


What is the correct way to install 1/4 inch break away nuts on aluminum tubing for the pilot light and gas valve fittings?

Slide it on the tube. Insert tube into valve/pilot, then tighten.

Do I slide the tube all the way down into the valve/pilot ports until the tube bottoms out, then hold the tube and start tightening the break away nut?

The reason I'm asking about the breakaway nut is because I was told I had a bad valve on my wall heater. I bought a replacement gas valve on-line at a cost of $50.00, which was not the same as the original gas valve. I then had to re-route the pilot light burner aluminum tubing. In the process of going through these changes, I broke the pilot light burner aluminum tubing. I then replaced the pilot light burner aluminum tubing and incorrectly installed the break away nut and then stripped the threads on the gas valve. I had to buy another a gas valve from a local hardware store at a cost a $104.00 and I am trying to avoid this from happening again. These gas valves are not cheap.

Do exactly like you said in reply #3.When you hear or feel "the break" then stop,you are done.

Thanks to all for replies. I am going to follow reply #3 after I install the new gas valve.
Hoping you all have a warm winter.

Cross threading will be you biggest concern.

beenthere:
I hear what your saying.
The new gas valve I bought came with an extended breakaway nut, not like the "NEW GAS VALVE" I bought on-line.
This will allow me to have more visual control of the aluminum tubing while I slowing tighten the breakaway nut.

I think their biggest concern should be that the new control valve is not the same as the original. It could be for a different fuel, designed to deliver higher BTUs, etc.........

@log doc rob, I purchased the Robertshaw 710-502 millivolt natural gas valve with a thermopile setup which replaces my "old" ITT General B67 gas valve.
