Fridge Question

I have a 17 foot Bigfoot with a IM30 3 way fridge
There is a side vent but no chimney on the roof. The wood gets real hot, just above the exhaust stack. Is this normal when it is on propane.

Does it look like this?

The top vent takes the place of the stack.

Hi David....yes it does look like that...I tried downloading a few pics but am having difficulty....I am so used to having a stack on the roof on other rigs I have owned and to me this vent does not really seem safe, but of course it has been used since 1981 and has not burned down yet...lol

Most of the small fibreglass trailer have this type of venting system.
The 19' Bigfoot, and the fifth wheel both have the roof vent that you are used to. I'm sure that there are others. I suspect that the longer chimney provides better air flow.

I'd be most uncomfortable with wood in the position you describe. My Trillium certainly doesn't have any there...Above the generating unit itself there's a metal flap and all other surfaces are (nonflammable) fiberglass.

Especially given the recent rash of RV fridge fires associated with wooden flued systems, I think you'd be wise to either remove the flammable wood, or if that's impractical, to install some kind of air-gapped metal liner .

I tried to put a piece of aluminum above the exhaust stack but it got so very hot in such a short period of time, that I just eliminated that idea. I had the fridge on for several hours yesterday and I guess I just jumped to the conclusion that the wood above it was too hot. It was warm, but not exceptionally hot, and it seems to be the original fridge so I assume the manufacturer installed it safely.

Well, it seems to have worked for 31 years so far, has it not?

Has the fridge ever been changed? The position of the vent/flue is to give the best draw pulling the cool air over the coils and out of the camper. The position of the vent/flue is mostly related to the height of the fridge. A flue coming out the roof would be okay but you'd be wasting a lot of space.

The heat as you describe it seems excessive and I'd consider putting in a fan to increase the airflow and draw out some of the heat.
