I recently bought a new Charbroil Kamander grill and wanted to replace the plastic intake tube & damper with a metal one provided by Charbroil. I'm hoping this will help with heat control which I think will be difficult with the plastic setup due to air leaks. I called Charbroil and they sent out a metal replacement kit for free. I received it today but was surprised to see that it's only the tube and doesn't include a new intake damper. I figured that maybe I'm supposed to use the plastic damper with the metal tube - but looking at the tube it doesn't appear to be the case. The new metal tube has two holes which seem like they would line up with the screw holes of the metal exhaust damper. So I'm back to thinking its missing a metal intake damper. However, before I call Charbroil, I thought I'd ask if anyone here has a Charbroil Kamander and knows how the intake tube is supposed to be installed - with the existing damper or with a new metal one (which Charbroil doesn't appear to have anymore). I've attached a few pictures to hopefully illustrate the issue. Any help with this problem would be appreciated!
