Questions about laying buried yellow poly gas pipe

[shaggyant]

I just finished digging the trench to lay my 125ish foot long run of 1 1/4” poly gas line to my shop. I’m looking forward to having heat this winter but I have two questions so far in the process.

1) Home Depot carries a bunch of sizes of poly gas line but they don’t carry the tracer wire in the store. Seems like every install would need this. Are people just using THHN for tracer wire? From what I’ve read so far online that is not correct. What does everyone use for tracer wire?

2) I want to lay a run of CAT6 Ethernet cable into the trench along with the gas line. Is there a reason this would not be acceptable? My shop internet connection. Would be way faster with this new wired connection over my current wifi reception so I am hoping this won’t be an issue.

I’d just run THHN wire and some CAT6 in a PVC conduit. That’s what my friend did in his shop.

Gas line, tracer wire and warning tape at the bottom of my trench and conduit about a foot above it

I went to an electrical supply house & got yellow 14 THHN wire solid.
Pretty sure it was about 1/2 the cost of something comparable at Home Depot.

Why such a big gas line? That's a ton of btus at 125ft

It’s not really. A 1” line at 125 feet is only 117k BTU. Then I need to add the piping inside the building along with bends. With an 80k hanging heater to feed I wanted to make sure I have extra capacity for a pool heater of bathroom water heater.

Ok, the o p said 1.25in line. Big difference
