Furnace Exhaust

[niftypkg]

How to keep rainwater out of Furnace exhaust?? Is it worth the effort ?? Would'nt traveling down the road in a rainstorm cause a lot of water to enter the exhaust and intake plate?? I've never seen it covered nor have I covered mine. Any thoughts??

Hi Tom,

I've never seen any of these little covers protected from rain. Maybe the inside design prevents water from entering. I have seen some of the furnace exhausts having protective lids, but that's so no one would touch the hot exhaust.
I have never seen water enter the vent, not even when washing the trailer with a hose.

Tom,

Good question. I have deinstalled a couple of the furnaces and the plate that the chrome cover sits over is made as an assembly. They are 4-6 inches in length. The intake and exaust tubes insert into the corresponding tubes in the furnace. I have not gotten out a level to check, but I bet if you could you would find that those openings are tipped down so water will run out by gravity. This would be caused by where the vent is cut in the skin, or by mounting the furnace up a bit in relation to the holes. If you think about it it is a simply elegant way to keep from obstucting the intake/exaust. When the unit is running I bet there is enough heat to keep it all dry!

BTW Suburban says that if you add ANY type of cover or screen to their furnace exaust, even to keep out the wasps and mud daubers you will void your warranty. So be sure to take it off before you take the unit in for service!

thenewkid, I managed to get a new [used] plate to replace the corroded original. So the original configuration is different! I'll take another look to check it out. Tom
