Section 3: System Configuration
SIZING RUN “B”
• Run “B” is sized by the load of the supplied appliance and the section length
• e load of the furnace is 80CFH
• e section length to the furnace is 15ft
• Referring to Table 7-21 (Pressure drop per foot for FlashShield™ CSST): for a 80CFH load, 1/2" CSST has a drop of 0.037"WC / ft
• e pressure drop over Run “B” is: 0.037" x 15ft = 0.555"WC
• e available pressure at the end of run “B” is 6.055"WC - 0.555"WC = 5.500"WC
SIZING RUN “C”
• Run “C” is sized by the load of the supplied appliance and the section length
• e load of the water heater is 36CFH
• e section length is 10ft
• Referring to Table 7-21 (Pressure drop per foot for FlashShield™ CSST): for a 40CFH load, 3/8" CSST has a drop of 0.075"WC / ft
• e pressure drop over Run “C” is: 0.075" x 10ft = 0.750"WC
• e available pressure at the end of run “C” is 6.055"WC - 0.750"WC = 5.305"WC
SIZING RUN “D”
• Run “D” is sized by the load of the supplied appliance and the section length
• e load of the range is 52CFH
• e section length is 20ft
• Referring to Table 7-21 (Pressure drop per foot for FlashShield™ CSST): for a 60CFH load, 1/2" CSST has a drop of 0.020"WC / ft
• e pressure drop over Run “D” is: 0.020" x 20ft = 0.400"WC
• e available pressure at the end of run “D” is 6.055"WC - 0.400"WC = 5.655"WC
SIZING RUN “E”
• Run “E” 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 is 20ft
• Referring to Table 7-21 (Pressure drop per foot for FlashShield™ CSST): for a 60CFH load, 1/2" CSST has a drop of 0.020"WC / ft
• e pressure drop over Run “E” is: 0.020" x 20ft = 0.400"WC
• e available pressure at the end of run “E” is 6.055"WC - 0.400"WC = 5.655"WC
SIZING RUN “F”
• Run “F” is sized by the load of the supplied appliance and the section length
• e load of the dryer is 28CFH
• e section length 5ft
• Referring to Table 7-21 (Pressure drop per foot for FlashShield™ CSST): for a 30CFH load, 3/8" CSST has a drop of 0.044"WC / ft
• e pressure drop over Run “F” is: 0.044" x 5ft = 0.220"WC
• e available pressure at the end of run “F” is 5.655"WC - 0.220"WC = 5.435"WC
SIZING RUN “G”
• Run “G” is sized by the total load of the supplied appliance and the section length
• e load of the BBQ is 25CFH
• e section length 5ft
• Referring to Table 7-21 (Pressure drop per foot for FlashShield™ CSST): for a 30CFH load, 3/8" CSST has a drop of 0.044"WC / ft
• e pressure drop over Run “G” is: 0.044" x 5ft = 0.220"WC
• e available pressure at the end of run “G” is 5.655"WC - 0.220"WC = 5.435"WC
