Is it possible to tap into a gas line to tee off for another appliance?

Two story house with the main living area upstairs. Garage is under the front half of the house, which is the living room and kitchen.

Here's why I ask. My main gas line (3/4" black iron) travels across my garage ceiling before it turns a 90 to follow one of the ceiling joists to the furnace in the middle of the upstairs. I want to add a gas line to my fireplace which is located nearly above where the gas line turns the corner in the garage. Problem is it would be extremely difficult to disassemble the gas line at the elbow due to the many connections involved downstrteam. But I'm thinking there must be a way to do this. Maybe not for me but a plumber would probably know how, I think... maybe.

Thanks... Randy

If it is too far to a union, the pipe can be cut, trimmed to length, threaded, and a tee and a union inserted. Unions are those 3 piece things that can be connected without turning either piece of pipe.

Good morning Randy,

Put your mind at ease Randy. All a plumber would need is a set of pipe cutters, a set of ratchet stocks with 3/4" dies, a 3/4" black iron street tee and a 3/4" black iron union. That would leave a 3/4" opening in your gas main that you could branch off from and reduce to 1/2 or 3/8ths copper to pick up your fireplace. Good luck, Tom

Pretty much what I thought I'd hear. I just wanted to see if there were any other options or ways of doing this.

Thanks guys.

Note, plumbers size pipe by nominal ID. If the pipe is about 3/4'' OD, you will need to buy fittings labeled 1/2''. Tubing and tubing fittings are often sold by the OD. When you go to buy pipe and tubing, take a tape measure. Running pipe isn't that bad of a job. Most places that sell the black iron pipe also cut and thread it. The silvery galvanized causes problems if used for gas or compressed air.
