Collar issue on DV360

[J-P]

I have a direct vent CFM DV360RFN, the collar kept falling off. After many months of trying to repair the collar I tried a smart thing, bending it in an attempt to keep it on. Sadly a few days later I found out that the model had a repair kit designed to keep the collar attached to the flue pipe.

CFM is no longer around and there are no spare collars available (please correct me if I'm wrong). So what options do I have ? Should I try to put it back in its original shape and risk a leak ?

Hard to tell from your pic, but I assume you're venting this horizontally.
I would try returning it to the original configuration, installing it & goobing (technical term)
a LOT of RTV silicone around the junction of the collar & the sheet metal box.
Maybe support it in position until the RTV sets up - 24 hours.
Then reinstall your venting.
If that doesn't work, & if you can get at the fireplace, I'd try making some small,
"L-shaped" sheet metal brackets.
Install them on the collar with zip screws & then zip screw the brackets to the stove.
Cover the screw heads with RTV to seal the venting.

Thank you for your suggestions! It's venting vertically, the mantle covers the entire wall making the repair difficult.

Here's the kit I ordered.

Those tabs on the repair kit are what I suggested with the "L-Shaped" brackets...
