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.
1 1 Place all of the ingredients except the pork in a small bowl and stir to combine. 2  Rub the spice mixture evenly on all sides of the ribs. 3  Place the meat in a resealable plastic bag or a baking dish covered with plastic wrap and refrigerate for 8 hours or overnight.ou can also purchase a pork shoulder or butt roast and cut it into âribsâ yourself. Game plan: To get the best results, let the ribs sit at least 8 hours with the rub on them; the dry spices will rehydrate and lend better flavor. You can go as short as 4 hours, but the flavor will be less developed.
