My hoods have 2- 15" stacks. The stacks on the syrup pan and the flue pan have a shallow funnel that came with the hoods. I had to make a channel to hang off the bottom of the funnels. They both are run into the gutter nearest that funnel. The syrup hood is attached to the flue pan hood but each is a complete hood. The gutters on the front hood have a 3/4" fitting and each has a plug installed. I removed one plug on the front hood and one at that corner on the flue pan hood and I connected them with copper pipe. Then at one corner at the back of the flue hood I connected a barb x MPT adapter and a length of 3/4" vinyl tubing hangs down into a bucket on the floor. I need to empty the bucket about every hour or it over flows. Had I planned ahead I would have a floor drain there. Before I had a tankless water heater I used the water in the bucket for some cleaning, I now just use permeate pumped thru the tankless heater.
Dave Klish, I recently ordered a 2x6 wood fired evaporator from A&A Sheet Metal which I will be converting to oil fired
Now have solar, 2x6 finish pan, 5 bank 7x7 filter press, large water jacketed bottler, and tankless water heater.
Recently bought another Gingerich RO, this one was a 125, but a second membrane was added thus is a 250, like I had.
After running a 2x3, a 2x6, 3x8 tapping from 79 taps up to 1320 all woodfired, now I'm going to a 2x6 oil fired and a 200-425 taps.
