• e total load of the supplied appliances is 36 + 52 + 28 + 25 = 141CFH
• e section length is 5ft
• Referring to Table 7-21 (Pressure drop per foot for FlashShield™ CSST): for a 150CFH load, 1" CSST has a drop of 0.006"WC / ft
• e pressure drop over Run “B” is: 0.006" x 5ft = 0.030"WC
• e available pressure at the end of run “B” is 5.440"WC - 0.030"WC = 5.410"WC
SIZING RUN “C”
• Run “C” is sized by the total load of all supplied appliances and the section length
• e total load of the supplied appliances is 52 + 28 + 25 = 105CFH
• e section length is 10ft
• Referring to Table 7-21 (Pressure drop per foot for FlashShield™ CSST): for a 110CFH load, 1" CSST has a drop of 0.003"WC / ft
• e pressure drop over Run “C” is: 0.003" x 10ft = 0.030"WC
• e available pressure at the end of run “C” is 5.410"WC - 0.030"WC = 5.380"WC
SIZING RUN “D”
• Run “D” is sized by the total load of all supplied appliances and the section length
• e total load of the BBQ and the dryer is 25 + 28 = 53CFH
• e section length 10ft
• Referring to Table 7-21 (Pressure drop per foot for FlashShield™ CSST): for a 60CFH load, 3/4" CSST has a drop of 0.004"WC / ft
• e pressure drop over Run “D” is: 0.004" x 10ft = 0.040"WC
• e available pressure at the end of run “D” is 5.380"WC - 0.040"WC = 5.340"WC
SIZING RUN “E”
• Run “E” is sized by the load of the supplied appliance and the section length
