Is the end of the duct that connects to the blower small enough to fit into the blower opening?
Answer Ed, No, the end of the exhaust pipe will not fit inside the opening of the blower housing, it has to fit over the end of the opening. Once you have it properly installed, you can use some metal/aluminum vent tape or a self drilling/self tapping screw to hold it in place.
The flexible tubing for the exhaust is round at both ends, but the wall connection is oblong. Do they make tubing which is round at
the end attached to the dryer and oblong at the other end?
Answer Hello Charlie! Unfortunately, we do not have the requested type of venting available. I would suggest contacting a local heating and air company or a sheet metal company to see if they can make one to the specs needed. Hope this helps. Thanks.
