SIZING RUN “C”
• Run “C” is sized by the load of the supplied appliances and the run length from the meter to the furthest appliance
• e total load of the supplied appliances is 2 x (50 + 25 + 28) = 206CFH
• e run length to the 4th floor Fireplace (furthest appliance) is 5 + 10 + 10 + 10 + 25 = 60ft
• Referring to Table 7-23 (Rigid pipe 0.5"WC pressure drop): for a 60ft run, 1" pipe has a capacity over 206CFH
(actual: 260)
SIZING RUN “D”
• Run “D” is sized by the load of the supplied appliances and the run length from the meter to the furthest appliance
• e total load of the supplied appliances is 50 + 25 + 28 = 103CFH
• e run length to the 4th floor Fireplace (furthest appliance) is 5 + 10 + 10 + 10 + 25 = 60ft
• Referring to Table 7-23 (Rigid pipe 0.5"WC pressure drop): for a 60ft run, 3/4" pipe has a capacity over
103CFH (actual: 138)
Sizing Runs E1, F1, G1, E2, F2 and G2 are similar to the sizing of E3, F3 and G3.
SIZING RUN “E3”
• Run “E3” is sized by the load of the supplied appliances and the run length from the meter to the supplied appliance
• e load of the dryer is 28CFH
• e run length to the dryer is 5 + 10 + 10 + 15 = 40ft
• Referring to Table 7-4 (2"WC pressure drop) for a 40ft run, 3/8" CSST has a capacity of 28CFH (actual: 32)
SIZING RUN “F3”
• Run “F3” is sized by the load of the supplied appliances and the run length from the meter to the supplied appliance
• e load of the fireplace is 25CFH
• e run length to the fireplace is 5 + 10 + 10 + 25 = 50ft
• Referring to Table 7-4 (2"WC pressure drop) for a 50ft run, 3/8" CSST has a capacity 25CFH (Check against fireplace
sizing)
• Referring to Table 4-6 (Fireplace Sizing), 1/2" CSST has a capacity over 25CFH (actual: 83)
• Using the larger result, this run will be sized to 1/2" CSST
SIZING RUN “G3”
• Run “G3” is sized by the load of the supplied appliances and the run length from the meter to the supplied appliance
• e load of the water heater is 50CFH
• e run length to the water heater is 5 + 10 + 10 + 15 = 40ft
• Referring to Table 7-4 (2"WC pressure drop) for a 40ft run, 1/2" CSST has a capacity over 50CFH (actual: 93)
SIZING RUN “E4”
• Run “E4” is sized by the load of the supplied appliances and the run length from the meter to the supplied appliance
• e load of the dryer is 28CFH
• e run length to the dryer is 5 + 10 + 10 + 10 + 15 = 50ft
• Referring to Table 7-4 (2"WC pressure drop) for a 50ft run, 3/8" CSST has a capacity of 28CFH (actual: 29)
