The condensate expelled from a condensing boiler is acidic, with a pH between 3 and 4. Condensing boilers require a drainpipe for the condensate produced during operation. This consists of a short length of polymer pipe with a vapour trap to prevent exhaust gases from being expelled into the building.
I used a Hormel 2.5 pound pork shoulder. I brined it for 24 hours and tied it up. I followed the recipe exactly. There was very little fat on this smallish piece of meat when I reduced the temperature from 425 to 325 degrees I brushed maple syrup on the roast.sing a pastry brush, spread the mixture all over the pork shoulder. Set the meat on a rack set into a roasting pan. Roast for 20 minutes, and then reduce the heat to 325 degrees F. Continue to cook until an instant-read thermometer inserted into the shoulder reads 185 degrees F, about 4 hours.
