How many of you using gas tank and your stove is located above oven? My rubber hose is running above oven as the connection point to stove is on right side while gas is at left of oven. Any chance the hose will melt when I operate my oven?

If you are concerned, you can opt for silicone based hose which should have a higher melting temperature.

Was at Ace hardware few days ago, it seems they only have standard hose, was looking for fire resistant gas hose btw.

Fire resistant hose?

Anyway, if you really want some good stuff, you can look for Toyox silicone hose (Made in Japan). You can find them at some of those hardware shop or hydraulic shop but it is not going to be easy to find. They are also quite expensive compared to those China/Malaysia/Thailand made hoses. They will last for quite long.

Those clear one with braids between the two layer also got 2 types. Cheaper one are usually pvc and they could probably handle 60C or so. Silicone based will easily handle over 100C.

I still had a 10M long Toyox hose that I use for car washing. Even after 15 years baked under sun, it is still soft and maintain the shape.

Yes is a concern as the pipe could melt as the oven heat is very hot

Appreciate all info shared. Saw some fire resistant hose in Google, dunno if it's appropriate for gas pipe though...LOL. Will look out for Toyox, unsure if there's a way to check exterior temperature of oven while running because it can easily go beyond 100c.

That's my concern because I do bake at times.

Even with other type of hose may not work also as baking can be high temp like 180 degree

My tank is on the left side of lower cabinet next to oven. Will be hidden inside the cabinet. Did a check with my existing kitchen, it's the same setup with rubber hose running above oven.

If you worry, can wrap the gas hose with the insulator, like the type use on a/c, forgot the name. Check the heat ratting.

Some place sell heat insulator for hose too.

I think the build in over heat dissipation are on the front. If you don't use the over for long hours will be ok.

Noted on insulation. So far no problem from existing setup that's been used over 7 years but just want to make it safe for prevention.

If using oven for baking can be more than 1 hour. And those oven that is build into cabinet had no outer cover and the heat will be from around the oven.

Ya, when baking butter cakes I usually used around 45 mins and running between 150 - 180 degree celsius. Will get something to isolate the pipe.

I won't be worry too much.

Clip the hose at the bottom of the table. (close to bottom table)

Oven have insulation around the body case. Even inside is 180c, outside is just warm. Definitely is alright for a gas hose.

If you still not satisfy, Use a flexible copper pipe run over it. Than joint a short gas hose with clip to the hob.

Only realized when everything is done. Found out about the problem while I'm connecting the gas hose to hob.

Noted. I'll run the over then check external temperature just to be safe. Thanks and much appreciate your input.

I think never use copper pipe for propane. Copper is a super conductive material plus it is also a very good heat conductor.

Most of the time, they used stainless steel pipe with gases. There are cases where they used copper pipe like those compressed air tank in palet but I never seen anyone using copper pipe with propane.

Copper pipe for gas delivery have been use for very very long time. Even before you born.

I have experience install copper pipe for gas heater from ground floor (gas tank) to upper floor bathroom. And even for kitchen.

For restaurant kitchen their jet engine cooker, there use GI pipe. Not SS pipe.

For consumer household, Flexible copper pipe or thick copper pipe will do.

It can stand the heat and pressure. (Consumer gas pressure is low). 1 of the example is your aircon gas deliver between indoor and outdoor unit. Touch the hot cooper pipe and you know how hot is it.

SS pipe also conductive, and also heat conductor, SS because of its price. Bending will have problem for SS if not done correctly. For non expose area copper were used, even on gas burner internal. Expose area many uses GI Piping for its strength and price.

AC Pipe also use copper, open up rinnai or any gas water heater, internal also copper. Even Instant water heater internal is also copper.

My bad...

Im not expert in this area. Just some of my clients insist on getting stainless steel for flammable gas application (we are just a steel trader).
