More than agree with the vent , it a good to have but its only usefull when the ovens damp and unusable. Prevent the water from getting is really what you want. If you don't want to cover it preventing the water from getting in is your aim. The cracks are from water trying to escape. A water tight cover on the front of the oven and a water tight chimney cover is your best insurance. Keep the water off that entrance brick. Take a cup of water pour it on the entrance hearth it will not be there long , its straight down those cracks and straight into those bricks. Then its into your insulation and from there its a long slow process to remove.
I like my oven in the open and have tried everything. Keep the hearth dry is the most successfully. I only did my final finish after being able to keep it dry

Yes that's him. Quite an innovator. Well you would know better than I...I only purchased one of his creations. I always get alot of attention out on the trail..."What is that?"..."Was it made in the US, do they still make them?" etc...You should hold onto that bike, it might be a collectors item some day. LOL Thats what I tell myself about my ATK but used ATK's are usually pretty cheap...or unsold.

But enough about Horst! What is Ken going to do with his oven?....take more pictures I hope!

I agree with that. But, without being totaly protected from inclement weather, humidity, and long periods of unplanned unuse, the vent is a great "fail safe" .
