Use the rise for thevertical aspect and the run for the horizontal aspect (seeFigure 5.1).Two 45º elbows may be used in place of one 90º elbow. On45º runs, one foot of diagonal is equal to 8-1/2 (216 mm)inches horizontal run and 8-1/2 (216 mm) inches verticalrun. A length of straight pipe is allowed between two 45ºelbows (see Figure 5.1).Figure 5.1Vertical12 in.8-1/2 in.Horizontal8-1/2 in.C. Measuring StandardsVertical and horizontal measurements were made usingthe following standards.1. Pipe measurements are from center line to center line.2. Horizontal terminations are measured to the outsidemounting surface (fl ange of termination cap) (seeFigure 4.1) on page 9.3. Vertical terminations are measured to the top of the lastpipe before termination cap.4. Horizontal pipe installed level with no rise.Heat & Glo • Paloma • 7031-220 Rev. S • 8/09 11
