I need to vent...

Here's a new twist on the catalytic heater. The exhaust could probably be combined with the furnace exhaust using a backflow preventer saving an extra hole in the shell.

good find excella'...

but it isn't new, they've been steadily making this product for 30 years at least, with tweaks, updates and improvements, sorta like wally...

this vented style cat was the preferred brand for many of the a/s dealers when cats became popular in the late 70s and early 80s.

my unit had one that saw duty for 20 years or so...

it is STILL the safest approach to using a catalytic inside an rv.

there are many options for the vent, depending on floor plan.

many are mounted near the entry door or galley cabinet wall or door...

and exhaust vented into the fridge compartment or furnace or other outside doors that are near by.

some of the models also included fresh air venting.

we've had many threads on cats and usually they include a link to this brand, if i catch the thread.

here is one from a user of a 27 year old model, that is still working!

so are u planning to install one? did you get a current price yet?

all of the true things that i am about to tell you are shameless lies. l.b.j.

we are here on earth to fart around. don't let anybody tell you any different. k.v.
