It s been quite an ambitious learning experience for me but it s also been a rewarding one as well.
How to install a gas line floor flange.
You do not need a floor flange and a floor flange is not made to couple two pipes.
I also had to add onto the existing natural gas supply line in my home to make this work.
Its not like a coupler for instance where a pipe can screw into both sides.
Remember to apply pipe thread compound or gas rated teflon tape to the threads on threaded connections before assembling them.
Again you are correct that a gas valve is needed near the dryer.
In a typical gas line installation teflon tape or pipe joint compound should always be used on the threads to insure there are no leaks.
On the stove end use another flare to pipe thread fitting.
The gas valve is installed to the treads of the compression nut after it the nut is installed into the flange.
Threaded pipe flange is supplied with a tapered internal thread that the pipe screws into.
In fact a floor flange is only used to make a supporting pier from pipe materials it is never used for pipes with any flowing fluid inside the pipes.
I did it myself and i have some great practical advice for installing a natural gas stove in your home.
Then use the adapter included with your hookup kit to connect the flexible gas line.
This is essential to establishing an airtight fit.
Coat the threads of the pipe ends using pipe dope.
Threaded flange find applications in areas in which hot work welding burning and grinding is undesirable.
It can come loose inside the pipe and can clog the line.
If using a pipe thread sealant tape wrap it around the threads and insert into the fitting.
Flare joints rely on a tight fit to seal and don t require additional sealant.
Extend your existing gas line by fitting the valves and pipe lengths you need to add a gas line that will reach your new appliance.
Never use tape including teflon tape.
