I am hoping to find a flue pan ASAP. a 2' x 4' drop flue would be ideal. My homemade arch is 2' x 7' and I have a syrup pan that is 3' long and I have a back pan which is flat and 4feet. Really looking for anything that will get my boil rate way up. I'm dogging it at about 15GPH and it's taking way too long. Did not plan ahead and take care of this in the summer and now I am paying the price.
