Insulate combustion air inlet piping when run in warm, humid spaces such as basements. Sizing Combustion Air and Vent Pipe Consult Table 3 or Table 4 to select the proper diameter exhaust and combustion air piping. Exhaust and combustion air piping is sized for each furnace Btuh size based on total lineal vent length (on inlet oroutlet side), and number of 90 ° elbows required. Two 45 ° elbows can be substituted for one 90 ° elbow. The elbow or el bows used for vent termination outside the structure ARE counted, including elbows needed to bring termination above expected snow levels. The elbow inside the furnace on the *9MPD IS NOT included in the count.
