Gas dryer--4" duct reduced to 3"


We just purchased a new gas dryer and noticed when examining the ductwork that the 4" elbow is reduced to 3" to go through the wall to the outside.

We have a 90 degree elbow out of the back of the dryer connected to a 2' long rigid duct connected to another 90 degree 4" elbow connector. This connector joins into a reducer (2-3" long) and directly into a 3" duct run through the wall to the outside (approximately 8" looks like). Is reducing down to 3" to go through the wall going to be a problem?

Not sure about your local code, but it would not fly here.

IRC M1502.3 says, duct size "as required by manufacturer". Most manufacturers recommend 4".

I don't know if it is a code issue, but I'm sure the dryer instructions will say to not reduce the diameter of the vent at all. It definitely isn't a good thing. I don't know if it is horrible though. It just may take more energy to dry your clothes and the duct work will probably clog up faster than it otherwise would.

Never seen one reduced and have seen quite a few, just keep it 4" like all the other millions of dryers in the USA.

It's 4" all the way out for a reason.

Thanks, we plan to replace with 4". This home was built in 1952 and I have since have been told that a 2.5" hood was common at that time.

It will suck a bit to enlarge the hole but it's the smartest thing to do. . . good luck.
