Code compliance: vent dryer to code


paintdrying, it is actually all over the board. Some places are stating 5 feet for a 90, another is 5-9. The site I linked to which I would trust more, is stating 15 feet for a 90 degree el. I would go with the last, just to be safe. I think that it is the 45 degree el's that are considered 5 feet of pipe run equal to.

i get it now. In that reference it says one 90 degree elbow equals 5 ft, while the 45 degree angle equals 2.5, that is the minimum to meet code. the 15 foot = 1 90degree elbow is just a "study" that was done. seems like they just want you to buy their product. I'm going to stick to minimum.

so it looks like i can get by with 8 foot straight run going up then one 45 degree elbow(equaling to 2.5 ft), a 2 foot straight run following the 45 degree elbow. After the 2 ft straight run follows another 45 elbow (2.5 ft) into a 7 ft straight run going outside.

8+2.5+2+2.5+7=22ft.



also Should i keep that black insulation on the end of the run or does that not matter?

Code in my area....14' with no more than 2 90's.

If you have 'any' flex, then no more than 6'.

So, yes....your way over.

when does the run actually begin. does it begin out of the dryer box, or does it begin out of the dryer machine

if it does start out of the machine, then do we have to factor another 90 degree angle

"The run" is inclusive of the very first elbow or straight piece that you attach to the dryer.

Starts at the dryer....and because you have that flex....your maximum run is 6'.....get rid of the flex....

Next dryer vent I am going to run I will call the inspector. Shorter the better, sounding like it is what the inspector will want to see.

Good plan. But I've never heard of a permit and inspection being required for a dryer duct.

We keep the washer and dryer on the front porch here to avoid just such a conundrum.
