The comment about the electrical wires was maybe a bit silly and emotional lol. The temperature is controlled by the number of holes drilled in the kiln, so if I follow the instructions I believe it will be reasonable.

The vent kit does come with the actual exterior part, like a drier vent:

I will probably swap the rain hood for one designed for a drier, as those typically come with back draft dampers and metal caging. I’m not too worried about animals getting in when the fan is on, but I’m not really basing that on anything.

The install instructions do have recommendations on when to switch to PVC pipe from the flexible duct, so I will be sure to follow those.

Thanks!
