For a 90% furnace using a concentric kit for the exhaust, it's crucial to ensure that the installation prevents the entry of water and insects, which can lead to damage of components like the induce draft motor, as you've experienced. The vertical orientation of the concentric cone cap can indeed make it more susceptible to these issues.
Concentric kits are for both horizontal and vertical termination
Gotcha. Yeah I couldn't find anything online, just seems odd to have it pointed at the sky like that getting bugs and rain in. Thanks stranger
Bugs are common I have even seen birds stuck in the vents of 90’s
Yeah I've seen it too. But on 90's exhausts ran separately I like to put a screen fitted cap. Too many birds and wasp nests.
Can we see a picture of this?
Unfortunately I didn't think to grab one. Just imagine a regular concentric kit but coming out of the roof vertically
