Rain coming in thru heater exhaut ports?

We have had some driving rains with heavy winds here in N. TX the past month and I went into the RV about 2 weeks ago and found water on the kitchen floor coming in from under the counter. Went outside to see where it might be coming down as after I took the inside access panel off I could see it running down the outside wall. Went outside and it looked like it was coming from the outside access panel for the heater exhaust panel. So after it quit raining i took the panel off and caulked around the panel and screw holes.

Another heavy wind rain this a.m. and went out to see if I had fixed the problem. Nope water in the grooves of the tile floor again. Coming from the same spot

I am wondering if the rain in being blown into the actual exhaust ports. I have now put plastic over the ports to see if it stops the water entry.

Any ideas anyone? Thanks!

Carol

Do you mean the "outside FURNACE access panel"... (in which your FURNACE exhaust and intake ports are located)?


ATWOOD FURNACE ACCESS PANEL



SUBURBAN FURNACE ACCESS PANEL

What is the make and model number of your furnace?

Yes like the Suburban Access Panel. Where do I find the make and model number, as if you had asked me prior to posting the pics I would have said Atwood, because I think that is what the paper says that shows the makes and model of all the appliances.

Because I have no removable access panel the model number of my Suberban propane furnace is only visible/readable when my furnace is pulled completely out into he coach.

However you should be able to see the your label on yours after you remove the outside access panel.

The exhaust duct of your water heater, and your furnace for that matter, should be sealed from everywhere but its own intake. There should be no way for water to enter the exhaust port and go anywhere but the intake port. Otherwise you'd also get exhaust fumes and flames in the same areas you now see water. Your search has brought you close, but the combustion chamber in its natural configuration is not the culprit

OK the equine dentist has left from working on the horses, so I have had a chance to check what the paper said on the applicances.

Front Furnace: Model NT20S

Rear Furnace: Model SF 35

Thinking it is the front one as the vents are mid coach under the stove top, but the ducts head to front and to the rear.
