is this sound normal for brand new 2 stage furnace?

we just bought a brand new 2 stage furnace (rheem rgrm-10) a few days ago. everytime the furnace starts up, we got some kind of clicking and rumbling noises. My installer said its normal for the ECM motor to make that kind of noises. what do you guys thinks?
here is the video clip of the noise

My Lennox (installed in 2006) doesn't do that and to my knowledge never has. I suggest that you contact Rheem directly and ask.

ECM motors tend to rock before starting, but yours seems very excessive...

I did send an email to Rheem (with the video clip of the noise of course), but got no respond from them yet.

They may not respond and you may need to find another rheem dealer.
