Flared copper pipe to joing iron piping

The home originally had a single propane tank that served the clothes dryer, and the cooking stove. We have since changed from oil heat to propane heat, and sometime this summer, the underground 1000 gallon tank will be installed. Presently, the heat is serviced by separate tanks, and when they did the iron piping, they left a stub to connect the rest of the house to. Problem is that at a certain point, I have copper running inside the walls, and I need to hook that up to the new iron piping. When I installed a new cook stove, I piped that with iron and connected it up to the original copper piping. Today, I removed the stub, and started installing the iron pipe, and hooked it up to the gas dryer without any problems. The problem comes with the stove, since that iron piping is at a different height than the new iron piping. I can use a union and a couple of elbows, *******, etc. to make the connection, but it is going to be a hassle, since I don't have a pipe threading machine. I was thinking of joining the two ends of the iron pipe with a short piece of flared copper tubing, like what was originally done in the home. Do you see this as a good and viable solution? The only other choice would be to make multiple trips to HD to have pipe cut and threaded, as I work toward the two ends meeting.

I ran my entire house with 3/4 black iron pipe. The furnace I hard piped by dropping down with 1/2 inch iron pipe . The other appliances stove, water heater and dryer I came off the black iron with 1/2 copper. You need like in my case a fitting called 3/4 NPT by 1/2 flare. You'll be good to go. By the way the iron pipe will make it so you get the correct volume where it's needed.
In the end in a perfect world one pipe stub should come out of the house and run to the new tank.
I have done propane systems for 31 years feel free to PM me. Mike

Decided to finish the job properly, and ran black iron to meet up with the rest of the black iron. Took a few fitting and a street ell to make it all work out properly, with a union in the middle to complete the job. Now, it is back to the electrical work to complete.

You have a union in the house?

I don't think that is code compliant.

Cannot use a union inside? Had no idea. Is this true?

A union is no more to leak than any other threaded fitting.

I believe code requires it to be accessible, so you can't like sheetrock it in a wall and forget about it.

Also a lot of jurisdictions also require a valve right before it so the gas can be cut off in case of a leak.
