Big Maxx MHU80

I just installed this in my garage and I have a noise (like a rumble) coming from my exhaust blower. I took all of my vent pipe off and when the unit kicks on it makes this god awful noise when it starts. I noticed that the blower wheel inside has a wobble to it. When it is running I can hear it outside of my garage at 20' away. Any suggestions?

Hot Dawg sounds like a can of rocks being shaken?

So I finally was able to test fire the Hot Dawg today. New install, 45k unit. When I first got it to fire up, it sounded like a can full of rocks being shaken up. Is this the direct spark ignition? Or is it something else? It seems to run ok, it blows warm air out that's for sure.

Have them warranty out the inducer assembly and replace it.

I tried to get a hold of them today but missed the hours they was there. Will try again Monday. When I saw the blower wheel wobbling I kind of thought that might be an issue. Thanks for the response.
