I got lucky and found an overhead natural gas furnace for $50 which has a
80k input/ 64Koutput rating. I have a max of a 50 foot run from house to
garage and I guess I should run 3/4" line. I think I plan to run iron pipe
from inside the house to outside the wall and switch to plastic underground
pipe to the garage and switch back to iron once inside. I'm open for
comments and suggestions on the proper way to do it...
Thanks

Get a plumber involved who can get the required permits and get the work
approved when it's finished.
Want to save some money, offer to do the grunt work to dig the ditch and
then cover it afterwards.

Lew's got a good idea. Black pipe is generally required (no sparks when fitting
or disassembling), as are supporting devices every 8 feet. Pipe dope (thread
sealant) the joints well, as it'll have to hold 15 lbs. of pressure for about a
half an hour. Tom

If you run it through a block wall it has to go through a conduit to
prevent the block from filling with gas if there is a leak.
Also you can't run plastic pipe into or out of a building (you wrote
"switch back to iron once inside").
There are also restrictions on electrical placements, distance from
entry point or some such, I have to re-read / decipher the section on
proximity again.
I'm sure others can/ will post better information.

I had the same situation last year. I only had to go about 15 feet
underground. I talked to a plumbing store and they said the only way to do
it was to use that plastic crap but the adaptors were like $60 apiece and
they only had 100ft spools of the plastic. I talked to another place who
was much more helpful. They said they do short runs like that all the time
by just burying the black pipe and coating it with tar. That's more like
it! I picked up a 5 gallon pail of tar from the Borg and a pair of rubber
gloves, buried the pipe and gave it a healthy coat of tar.
Now for all you out there jumping to your keyboards to flame me, keep in
mind that
1) this is my local outfit that gave me the advice - the people I would have
hired if I was not a DIY kind
2) this is exactly how they do it regularly for short runs
BTW, I used 3/4 inch pipe. Be sure to install shutoffs and check
throughouly for leaks!

The size of the pipe you should use (3/4" or 1")
depends on the capacity of the existing piping
system you are attaching to, as well as the
length of the run you are adding.
Consult the local building inspection office to
get help on chosing the best size for your application.

Who's going to terminate the HDPE gas line to a 3/4" adapter on each end?
Around here you need certification from the utility to use plastic pipe.
There is a plastic coated black pipe that would do the job, you have to use
some goop to protect the exposed joints from corrosion. In some localities
you can use galvanized pipe and coat it with tar. Check your local
regulations.
