The number of "adults" I have met who do not think they need to run the vent and/or open a window while burning gas in their homes is deeply troubling.

Routing our range hood to vent outside is the single best upgrade we've done to our house (but also the most annoying to DIY). I'd love to have induction but with gas the outside vented range makes the issue non existent.

Even with electric, range hoods should be required to vent outside always. I don't know why it's still legal to build homes that vent inside.

It isn't legal to build new homes that vent to the inside. In the US, there is no national build code, only states regulate code. But all states default to some minimum year of the ICC codes. At this point there are no remaining states where it is legal to have a new build vented inside.

This isn't to say though that some states were late to adopt a minimum year that finally included it and maybe your semi-new-ish house just barely fell under old regulations when it was built. That said, cities can also enforce a higher code if the building is being rented out and needs to have an occupancy license and may force an owner to do the upgrade before renting out.

Oh that's awesome! The last new build I rented was built in 2013 (Ohio) and it didn't vent outside, maybe just missed the cutoff.

To be fair, there are several 'types' of home that have ways of avoiding building codes. For example, Alaska is notorious for the most lax building codes and easiest to get around. Want to build your own bushman log cabin on your 100 acres that barely passes as a shack but won't immediately kill anyone? Go for it. But if you are a track home builder trying to stand up a new neighborhood, follow the code.

Huh never realized that for gas but makes sense. Parents had a gas stove that I hated turning it on as a teen cause if it didn't light I felt like I had to wait some time, don't recall thinking of the fan even then which would have been the obvious solution but then I wouldn't be sure the gas hasn't accumulated cause well no Google back then to check.

Usually gave it like 4 clicks (of the spark trying to light it) if not lit then wait a bit. I sort of wish I understood gasses better, even if I knew high school chemistry well at the time. Never had a gas one since I've been adult to think of that part.

The gas wouldn't have gone upwards into the vent. It's a heavy molecule for starters, but also just depressurized on release, making it colder. It'd sink down. The reason the vent is important when running is because the gas fumes are going to be significantly heated and rise via convection.

[-] theneverfox@pawb.social 1 points 1 day ago

It's pressurized though. It's basically sprayed upwards in a cooktop, it's not going to rise but it'll mix into to the air for a good while

[-] XeroxCool@lemmy.world 3 points 1 day ago* (last edited 1 day ago)

Look at the way it jets out. It jets sideways. The preview picture to this article even shows it. The only thing curving the flame upwards is convection. The instant the gas is out of the jet, it's depressurized

I've spent a lot of time testing and modifying my hvac and general home circulation. My main tool is a smoke pencil, basically a pushbutton vape. Air is stupidly stagnant. Suction vents have stupidly low influence over the air even within arm's length of the duct. Convection is the only thing carrying stove gasses upwards and if there's no heat because it's not lit, the methane isn't going up on its own. Just diffusing into the air with a preference for sinking. But the amount coming out is pretty low for a reasonable lighting attempt and the dangerous ignitable level is much, much higher than what that attempt will dispense. A couple flaps with a hand towel or toaster tray will disperse it plenty for good measure

You should open the window regardless of gas.

Cooking is not an environmentally friendly action lol, and it also releases plenty of bad shit for you to breathe.

Life isn't perfect guys, sorry bout it.
