NATE and ACE have been working to replace an older gas furnace with a more efficient furnace. They have determined that the new unit is a Category I appliance. They are going to use a 5-in. Type B venting system. The next step in assembling materials for the job is to determine the length of the system. (See Figure 1 for a schematic drawing of the installation.)
ACE: “Why are we going to pick up 30 ft of vent piping when, according to my calculations, we only have to go up 24.5 ft to get through the roof? With the termination cap, we’ll be around 25.5 ft. Extra material cuts into the profit for the job.”
