Problems with range hood installation.


I have two questions about some problems we are having with our zephyr range hood.
1) The hood is installed and the old exhaust cap is installed on the outside wall. There is about 5 ft of duct needed between them, and apparently there is no length adjustable duct pipe available. I can't figure a way to maneuver the elbows so I can find enough space to install the last straight length of duct pipe. Will I have to drop the hood again to finish the job?
2) We already dropped the hood earlier because we had to have a warranty repair, the switches weren't working. I'm thinking a larger size wood screws because the screw holes are wearing out with all this installing and uninstalling. Would larger size wood screws make the installation safe? This is a heavy range hood.

Here it is. Two elbows in the cabinet, attached to an elbow going through the wall. I'm having a local plumber shop make a 12 inch duct pc with the ridges at both ends but I have no idea how I will squeeze it in between the last elbow and the range top. Except for dropping the range hood.

Kick this back to them and their sheet metal guy to devise a solution
It won't be done with standard fittings or prepackaged lengths of pipe.
Allow about $100 for the work (probably less).

I can't quite figure why you are having such a hard time. I have almost exactly the same setup for my hood. I used two adjustable elbows, and made up about 20 feet of duct using 6 inch diameter galvanized steel duct. I cut the duct to the appropriate length using a Sawzall after assembling. I removed the outdoors outlet, installed the pipe effectively flush with the outside wall, and installed the outlet. Duct tape over the joints, project complete. No need to remove the hood.

Problems with range hood installation.


1) Difficulty because I want to reuse the old installed outside exhaust cap. I thought it would be easy to adjust the ducts between the outside cap and the range top but duct is not as flexible as I thought it would be.
2)Deadlines with wife. I am way behind on finishing the kitchen. I would like to knock off the outside cap and build the whole thing from scratch, but there would be a learning curve, plus my other work, might delay things a week. Wife would be furious. She has been upset for weeks already!

I worked with duct a year a ago, and admired the ingenuity of how the duct elbows worked. I assumed there must be a similar ingenious solution to allow the straight lengths to adjust how long they are. Wrong.

In my earlier post I misinterpreted your problem as being serious. It isn't.

Got the job done, found I could wiggle the elbows more than I thought. Wife will be satisfied.

If wiggling your elbows is enough to satisfy your wife...
