Installing gas pipeline over the roof.
Before we reroof, I'd like to run a gasline over to the fireplace, and also to the kitchen (we're remodeling that as well). Anyone know how this is done? Permit required?
There should be a permit required for gas lines but your plumber will know for sure. I assume youll have him do it rather than DIY?
We had a gas line run over the roof and down into a kitchen wall when we redid our kitchen. It just sits on pieces of 4x4 on the roof. Definitely needed a permit, and the inspection included a gas leak test before we could hook up our stove. Obviously you need to reseal the roof around the pipe entry point.
I was planning on DIY - ran an internal line a few years back - not complicated but didn't have to contend with earthquake country. Looks like I will need professional install.
Foam roof will be redone afterwards. Just want to get everything handled before the reroofing.
thx
Have you thought about converting your electric dryer to gas also.
Here's what I'm dealing with now.
I just moved to Silicon Valley from NY and know about the electric fiasco from 2 years ago, and expected to be kicked in the teeth since everything in the house is electric (compared to gas in NY for everything that can use gas). My first bill wasn't outrageous; in fact, my gas was 40% (just for radiant heat) and electric was 60%. So far, so good.
Then, I got hot & bothered by the day heatwave since arriving here in May and looked into mini-split A/C. A contractor said my electric panel is 100A and I have service for 75A (I haven't confirmed it myself); he can add another 20A for AC but said the 25% safety margin he likes means my main 100A breaker may trip on heavy loads or the panel will run warm; the first would be an annoyance but the 2nd could make me lose some sleep over it. He said replacing the panel to 200A service is $1,700 minimum; the alternative is to convert my dryer to gas and use the freed-up capacity for A/C. The price tag is a "couple of hundred dollars" for a gas tap for a dryer and a new dryer, probably $1,000 total, so my original estimated "budget" for A/C goes from $5,500 to $6,500+ which may break my will to have A/C (my wife wants BR furniture instead).
So perhaps the gas thing has implications for your electrical needs.
Your suggestion was our first consideration. Electrical panels were upgraded by previous owners so we have plenty of juice. Gas vs electric costs to run the dryer are comparable. My wife's preference is electric. We've purchased new electric dryer so although gas would have been easy to drop down, its not needed. Thanks for the reply.
Regarding permits: In my town, I believe you need a permit if you extend your gas line more than 4 feet.
So you can do 4 feet one day. 4 feet another day, etc...
To make a long story short, we have a lovely new gas line in our kitchen. :wink:
I just got several quotes on running a gas line.
My plan was to come from the meter (you should not "T" off from the water heater) across the roof drop down for the fireplace, Kitchen, and laundry area.
Quotes ran from $4000 to $12,000
I thought about doing it myself but decided against in when I thought it out. The long pipe run would require a lot of connections, (more chance for a leak) The roof also has a slight incline and Pipes would have to fit the roof line. I also found out they should have a spacer between the roof and pipe.
Because of the cost I put this project on the back burner.
Yes a permit is required in Walnut Creek.
Good Luck
What are the 'rules' and 'codes' for gas appliances as regard to venting.
I thought all gas appliances needed to be vented to the outside. But on the Orange County Eichler tour a few months back I saw some homes where they remodeled the kitchen and added gas ovens/cooktops but no vent was provided (at least that I could see). Some kitchens had a gas cooktop but the vent hood just vented back out to the room and they had remodeled the space above the kitchen cabinets w/o a 'flue' and it didn't look like it was a 'jenn-air' type cooktop.
Coming from the East Coast where gas stoves/ovens are normal. they are not "vented" like a dryer or water heater.
The exhaust fan above the stove is to exhaust hot air & food odors rather than poisonous gases; non-vented stove overhead hoods that you saw should have a grease filter (typically charcoal), but you saw that it blows hot air back into the room.
Gas stoves/ovens are perfectly safe without venting; in fact, they operate at maximum to burn off crust just like an electric w/o venting.
Another gas appliance is room gas heaters; you may have seem them sell for $100 or more. I don't know whether they are required to be vented but should since they are combusting in a closed room and produce high BTU; I've definitely seem them with oxygen sensors.
