Get an OCD detector, too.
you just can't pay enough attention to that stuff.

Almost a disaster in progress going on at my house. Bought a new gas stove to replace the electric one. It sits next to an interior wall, and to make a long story short...
The previous owner framed up a big sheetrock edifice thing to accomodate the microwave oven / vent hood over the electric stove. Getting a look at the underside of it with the microwave gone, I can see that the only way to vent it out thru the roof is to (maybe) run it out thru the same flue that services the gas water heater downstairs. There's one of those pie-plate looking covers on the flue inside the "edifice", facing towards the stove. That is, IF a human being can figure out a way to get their hands up in there and assemble and fit a flue.
Section G2424.8 is amended to read as follows: G2424.8 Equipment not required to be vented. The following appliances shall not be required to be vented:
1. Ranges.
2. Built-in domestic cooking units listed and marked for optional venting.
3. Hot plates and laundry stoves.
4. Type 1 Clothes dryers (Type 1 clothes dryers shall be exhausted in accordance with the requirements of Section G2437).
5. Refrigerators.
6. Counter appliances.
___________________________________________________________________________________ Your unit may or may or may not require venting. I would consider it from both a CO as well as a cooking grease build-up on the wall standpoint.
Does your vent-a-hood discharge it's exhaust into your attic or does it recirculates the air and use an activated charcoal type filter? If the hood exhausts into the attic and you have vent panels on your soffets and eaves you're good to go. If it recirculates there is the issue of replacing the charcoal filter periodically.
Your stove's paperwork will probably recommend following all "applicable national & local codes" so it might take a little digging to find the preferred installation in your jurisdiction.

It does't?
{Kinda makes you wonder why the big deal with venting things like your water heater and gas fireplace. No? But that’s the way it is.}
Because of carbonmonoxide, that’s why!
I know two families that lost their lives because of an improperly vented water heater!
These appliances burn more quantities of nat gas or lp than a range.
A typical WH burns 45 cubic feet of gas an hour, a furnace will burn 100CF on the low end. In other words a 125,00 btu furnace burns 125CF where a range burner may be 5CF or less.
1000btu = 1 cubic ft.
Unless you are qualified do not tamper with venting systems.
It is also a goos idea to have your system checked once a year to make sure is is working properly!
That was a quote off an inspector’s forum. Obviously it wasn’t clear that it was a quote.
I have a gas stove and the house had one when I moved in (which I replaced with my current stove). IT IS NOT VENTED.
That being said, my house was built in 1910 and building codes, even if the DID exist in 1910, have changed over the years.
How do you even vent a gas stove? As far as I know, you can’t. The oven vents to the outside (i.e the kithen) just above the cooktop, where the hot gasses can become a convenient plastic container melter. And the cooktop burners can’t be vented - practically speaking - because the flame is under a bunch of pots with food in them.
Are you talking about the vent hood? With the light and fan that can be manually switched on and off? These come in two styles. One style vents to the outside and the second style just blows the cooking odors and moisture back out into the room after running them though a charcoal and aluminum mesh filter. A grease trap and not much more.
I don’t believe the second style is up to modern codes (i.e. code now requires that it be vented outsided), but often older houses are grandfathered in based on the fact that they are old.
***Failure to ventilate the kitchen can lead to what appears to be black soot all over the house.****
Better check your air to gas adjustments. The flame should be BLUE, not yellow.
I have never had a problem with soot from my natural gas cook stove. My mom did have trouble with her heating stove years ago when squirrls plugged up her chiminey, but she was trying to use a propane stove on nat gas with a very yellow flame. When she cleaned out the chiminey and replaced her heating stove with a nat gas one she never had another problem.
Not only that, some of the range hoods simply filter out the smoke and vent the exhaust directly back into the room.

Also - I have a CO detector with digital readout. Much to my surprise, my gas stove, even when the oven and multiple burners going, has never causes any elevated CO2 readings.
Go figure.
That picture is a sure cure for attention deficit disorder. I could stare at those eyes all day.
I assume you are talking about a KITCHEN COOKING STOVE. It does not need to be vented. There is enough air infiltration to take care of the problem.
Vents over cooking stoves are used to capture cooking oders and grease, then the air is moved back into the room.
I would not have an electric stove on a bet! When the power goes out in an ice storm the cooking stove can still be used as heat, just make sure there is some air leaking in somewhere.
Gas stoves with open GRILLS on them, like a barbeque grill do need to be vented. General cooking they do not.
LOL. Thanks for a good laugh!
I used to have a ductless range hood built into the 15 year old microwave over the range. I replaced it with a vent to the roof to allow for high-velocity fans to vent smoke from a fryer or whatever I’m cooking that might be smoking.
It’s not difficult to do with the right resources and knowledge. The roofing part is the most complex, but once you understand roofing, it’s not hard to make changes without causing leaks.
While vent hoods are not necessary for LP/NG, they are recommended for professional/commercial setups, and a CO detector is one of those “why not have it” sort of items. I have a fire extinguisher under the sink for that eventuality, but I’ve never had to use it, thank God.
There is a place for most everyone under God's blue sky...
Yes, that’s right. The range hood, in this case the range hood / vent that’s built into the microwave oven. The kind of that’s designed to fit under a cabinet over the range and vent cooking gases out thru either the roof or wall. Or, alternatively, back into the kitchen using a charcoal filter.
2) If you do vent them (for example via an exhaust hood) you are NOT allowed to common vent such exhaust with that of another gas appliance (for example via a common flue with a water heater, furnace or boiler).
3) If you do decide to vent the exhaust to the exterior, the installation needs to comply with IRC M1502.1:"
"Range hoods shall discharge to the outdoors through a single-wall duct. The duct serving the hood shall have a smooth interior surface, shall be air tight and shall be equipped with a back-draft damper. Ducts serving range hoods shall not terminate in an attic or crawl space or areas inside the building. Exception: Where installed in accordance with the manufacturer's installation instructions, and where mechanical or natural ventilation is otherwise provided, listed and labeled ductless range hoods shall not be required to discharge to the outdoors."
(In the typically convoluted language of the code that does NOT mean "Range hoods must be vented to the outdoors", but rather that "if they are, they must meet the listed requirements".)
You start answering this question by using two sources.
First, contact the manufacturer and get their installation and venting specifications, which they will have in writing. You probably already have this in the manual that should have been packaged with the new gas range.
Second, contact a licensed HVAC installer to check on local building code requirements. You always install things to whatever is the most stringent, the manufacturer or the building code.
Last, do not combine vents unless the ducting is 1) designed by a licensed engineer and 2) is allowable under the manufacturer and building code specifications. If anything is screwy on vents from any gas fired device hazards to life and property can be created. This isn’t something to mess around with.
You’re talking about a gas range/oven for your kitchen, right?
I’ve never had, nor seen, one that needed venting to the outside.
That needs more clarification, whatever code that is. I have never seen where ant residential bathroom fans or stove hoods have ant make-up air (MUA) provisions.
Larger commercial exhaust systems do require some source of MUA to prevent the space from becoming negative with respect to the ambient (outside) condition.
ant = any
