Stove Pipe Help

[reidharrington]

I have a 1/2 pint oil fired evaporator that I need to exhaust through a shed wall. I am having trouble finding what I need to adapt from the evaporator to the double wall pipe and then go through the wall. It seems like I need a single wall to double wall adapter, the pipe and then a wall thimble. Can anyone point me in the right direction? A few pictures below of what I am trying to come off of. Thanks for the help!

Amazon has everything you need: https://www.amazon.com/s?k=triple+wall+stove+pipe+adapters&ref=nb_sb_noss

Any stove shop should have the individual pieces too, or a good hardware can order it.

Depending on what brand and diameter of pipe you are using this is an option

They make versions that are longer as well

The exhaust is to low, the heat is going to pass under your pan up the stack, the path of least resistance. You need to make the heat travel closer to the bottom of your pan. Maybe put a baffle over the exit facing up so the heat touches the pan before it exits the evaporator, like an upside down ramp all the way across. Leave it 2 inches down from the pan. I built the same thing as you 20 yrs. ago and it would not boil very well. That is why I guess the stacks go straight up on conventional evaporators. I hope this helps. You did a nice job building it.

I actually did not make it, it was purchased from Leader maybe 12 years ago. I just refurbished it.

I also have firebricks that have not been installed yet that make a short wall about 24 inches back from the burner.
