Gas Pipe - Limitation on Location?
 
Are there any limits on where you can run gas pipe?

In other words....can I run it in a false ceiling to get it over to a laundry room?

Depends on your local. They run in false ceilings in places like Micky D's, Burger King, Taco Bell, KFC, etc, so why not in a house.

I don't think gas code allows unions or valves to be closed in. Other than that you can run gas lines in false ceilings. Check your local code.

Different materials different installation requirements by code. Gas work is best left to licensed contractors that pull permits and have the work inspected.

Not every place requires permits or inspections for gas line installs.

I don't see drop ceilings in this

SECTION 404 (IFGC) International Fuel Gas Code PIPING SYSTEM INSTALLATION

404.1 Prohibited locations.
Piping shall not be installed in or through a ducted supply, return or exhaust, or a clothes chute, chimney or gas vent, dumbwaiter or elevator shaft. Piping installed downstream of the point of delivery shall not extend through any townhouse unit other than the unit served by such piping.

But this is only (1) code of many.

I have permits for all the work on my 2-story addition.....and I'm doing all the work myself....every single nail.....every single pipe.....you can see the progress so far by clicking on the "2-Story Addition Build" link in my signature.....

As for doing the piping....it's about one of the easiest parts of my addition....and yes, I know how to thread pipe.....and yes, I know not to use unions or valves in inclosed spaces....the only valves will be at the POU.

My existing house has a crawl space and all the gas plumbing is down there. Where I need to go in the addition, the most direct route is through a drop ceiling that I will have in the downstairs bathroom...

You should have no problem doing this.
I assume you have sized the new line as well as the capacity of the existing piping. Can it handle the the added demand?
How about testing? Do you have a plan?
I'm not asking these questions because I doubt your ability- just want to help. :thumbsup:

I'm ok on capacity....as long as I keep the lines 3/4" most of the way.

Main Forced air heater is 60K BTU, water heater about the same....gas stove top uses almost nothing...gas dry about 25K BTU (I think) and then a gas fireplace upstairs....60K.

I did some quick calcs based on 'the internet'....because my runs are not that long from the source and branch out....I should be good....I believe my gas pressure is 5" or about 0.2 PSI. If need be, the gas company will crank it up.

As for testing....when done, I'll close off all the POU valves, break the line loose at the meter and pump it up to about 20 PSI and leave it blocked with a gauge on it over night....leaks are not allowed in my house.

One word of caution- disconnect your supply lines from the valves and cap or plug the valves. If any of the valves do not have 100% shut off you'll be putting your test pressure against the appliance which are not rated for that.
