Just took delivery of the new stove. It is designed for a 5 inch flue, and my plan was to install a 4.5 inch single wall flue with silicone and fire rope.
As you can see from the pictures attached, the flue collar is a little larger than expected. The 4.5 inch flue will still fit and surround the internal hole of the stove, but the gap to fill all the way around is about 10mm.
Will it still be acceptable to seal this with envirograf silicone and fire rope? If so, what order and procedure would you recommend? If not, would you recommend a reducer like this:

Any help appreciated!
Also while I'm here, can anyone recommend a white or off-white enamled stove paint for the flue? Cannot find a thing
