59CU5A: Installation, Start-up, Operating and Service and Maintenance InstructionsManufacturer reserves the right to change, at any time, specifications and designs without notice and without obligations.42Table 18 – Maximum Equivalent Vent Length - Ft.NOTE: Maximum Equivalent Vent Length (MEVL) includes standard and concentric vent termination and does NOT include elbows. Use Table 19 -Deductions from Maximum Equivalent Vent Length to determine allowable vent length for each application.A13110Table 19 – Deductions from Maximum Equivalent Vent Length - Ft. (M)NOTE:1. Use only the smallest diameter pipe possible for venting. Over-sizing may cause flame disturbance or excessive vent terminal icing or freeze-up.2. NA - Not allowed. Pressure transducer will not close, or flame disturbance may result.3. Vent sizing for Canadian installations over 4500 ft. (1370 M) above sea level are subject to acceptance by the local authorities having jurisdiction.4. Size both the combustion air and vent pipe independently, then use the larger size for both pipes.5. Assume the two 45_ elbows equal one 90_ elbow. Wide radius elbows are desirable and may be required in some cases.6. Elbow and pipe sections within the furnace casing and at the vent termination should not be included in vent length or elbow count.7. The minimum pipe length is 5 ft. (2 M) linear feet (meters) for all applications.8. Use 3-in. (76 mm) diameter vent termination kit for installations requiring 4-in. (102 mm) diameter pipe.Unit Size 60,000 80,000 100,000Altitude(feet)Pipe Dia.(in) 1 ½ 2 2 ½ 3 1 ½ 2 2 ½ 3 4 2 2 ½ 3 40-2000 20 100 175 200 15 55 130 175 200 20 80 175 2002001-3000 95 165 1851049 125 165 185 15 75 165 1853001-4000 16 90 155 175 115 155 175 155 1754001-45001585 150 170 44 110 150 1651070 1704501-5000 80 145 165 44 110 145 160 65 150 1655001-5400 75 140 155 41 100 135 150 140 155Pipe Diameter (in): 1-1/2 2 2-1/2 3 4Mitered 90º Elbow 8 (2.4) 8 (2.4) 8 (2.4) 8 (2.4) 8 (2.4)Medium Radius 90º Elbow 5 (1.5) 5 (1.5) 5 (1.5) 5 (1.5) 5 (1.5)Long Radius 90º Elbow 3 (0.9) 3 (0.9) 3 (0.9) 3 (0.9) 3 (0.9)Mitered 45º Elbow 4 (1.2) 4 (1.2) 4 (1.2) 4 (1.2) 4 (1.2)Medium Radius 45º Elbow 2.5 (0.8) 2.5 (0.8) 2.5 (0.8) 2.5 (0.8) 2.5 (0.8)Long Radius 45º Elbow 1.5 (0.5) 1.5 (0.5) 1.5 (0.5) 1.5 (0.5) 1.5 (0.5)Tee 16 (4.9) 16 (4.9) 16 (4.9) 16 (4.9) 16 (4.9)Concentric Vent Termination NA 0 (0.0) NA 0 (0.0) NAStandard Vent Termination 0 (0.0) 0 (0.0) 0 (0.0) 0 (0.0) 0 (0.0)Long Medium MiteredConcentricStandard 2-in., 3-in., oroptional 4-in. termination.ELBOW CONFIGURATIONS VENT TERMINAL CONFIGURATIONS
