Extending gas line for a gas cooktop

Hi,

I am planning to replace my electric cooktop with a gas cooktop. I would appreciate any suggestions for contractors and things to watch out for from folks who have a gas range/cooktop.

I am also interested in learning about any aesthetic issues you faced while running the gas pipe and how you have solved it.

Thanks in advance

It depends on if you are running it to an island, or if is connected to an exterior wall. In island applications in Eichler homes, it is requires a few extra steps. First, you have to sawcut and remove the slab floor (and repair any radiant line damage). Then a gas line must be encased in a 2"pvc chase that is vented to the exterior and stubbed through the slab to the new island location. (We just finished a rough-in of this application). If you are connected to an exterior wall, Then the gas line can be either buried and run the exterior to the gas meter, or penetrate the roof, run along the surface of the roof to service, then re-seal the roof penetrations. Also, a as cook top requires a shutoff valve in the cabinet below; and a cooktop/oven will reqiure a gas shutoff in an adjacent cabinet.
For the most part, a retrofitted gas line can be concealed in the walls and ground, or will be exposed on the roof, unless you are planning to re-roof at the same time.
As far as a referral, email me and I might be able to refer someone, depending on your time frame and location.

Hi Ron,

Thanks for the reply. I will contact you directly for referral. What are your thoughts on running the gasline, tacked to the foundation slab, 6-9 inches about the ground line. Are there safety issues in doing so? That seems to me to be the least elaborate and relatively aesthetic approach.

I am not so much interested in running a gas line to my kitchen island, but a tiny water supply for my refrigerator. Does anyone know what the requirement for this are ?

Thanks

We took a different approach after being told that, by code, one couldn't run a gas line under a slab in a living space anymore. We ran the line over the roof and dropped it down inside the hood vent and into the wall behind the stove.

That is a interesting topic; certain municipalities prohibit installation of below slab gas, but the United Plumbing code allows it if encased in a pvc chase, vented to the exterior; we just had the county of San Mateo sign off on that application last week.
As far as running a supply line to the fridge; if you want to avoid opening the walls and there is a cold water source along the same wall, you can have a 1/4" or 3/8" copper tubing line run through the back of the cabinets for a water supply (depending on the requirements of the appliance).
If you have original paneling, it is very easy to remove and re-install properly, it really is worth the effort.
Email me if you need a plumbing referral.

I need to route the water to an island which has is no water or gas at all (just electric). I was thinking to cut open the slab (my radiant heat does not work anymore) when I am redoing the kitchen floor, and to route a thin copper line from the sink to the refrigerator nook.
Are you aware of any code restrictions with regard to domestic water in the slab?
Please email me with plumber referrals. I need someone who serves the east bay. my email is eichlerfan at stahl-clan dot com.

Thanks.
