what is gas oven vent venting?

[kaneohe]

Trying to use gas oven (2yrs old) in gas range as low temp (180deg)
dehydrator. In the olden days, instructions were to have oven door open
a little bit to allow moisture to come out. This gas oven has a vent on the top of the range as well as something on the front (can feel air flowing) and
as I understand it from rep something on back. Do any of these vent from
the interior of the oven and so would allow moisture from food to escape or are they for combustion byproducts from the exterior (don't know how an oven is constructed ).

gas ovens I'm familiar with are venting both combustion and food moisture and byproducts. No chimney going up from the range, right?

calmloki............no, no chimney. Thanks for the fast response. All I got from GE
rep was reading from her screen w/ no understanding.....kind of like me......so I appreciate your response. The oven light comes on when door is cracked open so
this will help lifetime of bulb. Stores aren't open for another hr so couldn't call there either. Thanks again.

edit to add: I guess another question would be: even if oven vents are venting from interior oven, any reason to think that leaving oven door cracked open a bit would help the dehydration process significantly? Why did
recipes call for that....at least in the old days

Lots of moisture produced burning natural gas - if you are also trying to dehydrate food I would guess that having the door cracked lets lower moisture content room air in to carry food moisture away rather than just the high moisture content combustion air. Could be way off though - our 40's era gas range has holes in the bottom at the sides and another hole at the top back.

Thanks again.....yeah, found a similar comment on google. Guess this calls for a real life experiment to find out the real truth.... for this oven anyway.
