I had a similar problem, but fortunately it didn't divert any moisture inside.
In my case the floor mounted furnace wasn't resting flat on the floor (at wall) which put the weight of the furnace on the outside plastic exhaust pipe extension thus compromising the outside exhaust pipe assembly.
I found that Jayco's clearance hole through the wall was located 5/16" to high..., so I modified the clearance hole so the furnace would rest flat on the floor resulting in the outer exhaust pipe assembly fitting properly into the furnace exhaust pipe.
