Burnham FCM120 Figure 9.2: Piping Method #1 - Heat Only

Example (contd.)

Total fittings in Indirect Water Heater Loop: 5 90 Elbows

2 Turns in Tees

1 Swing Check

2 Isolation Valves

Calculate total equivalent length from Table 9.7:

20 Straight Pipe + 5 Elbows x 2.75 + 2 Turns in Tees x 5.5 + 1 Swing Check x 7 + 2 valves x 0.6 = 52.95 Equivalent Feet Straight Pipe. From Table 9.6, we see that smallest circulator which will pump at 8 GPM through a FCM120 with 52.95 equivalent feet and an indirect water heater pressure drop of 3 ft is a Taco 0014.
