NOTE: Maximum Equivalent Vent Length (MEVL) does NOT include elbows or terminations. Use Table 2 - Deductions from
Maximum Equivalent Vent Length to determine allowable vent length for each application.

*Not all families have these models.
Notes:
1. 3 --- and 4 ---in. Vent pipe systems require long radius elbows.
2. Total equivalent vent lengths under 10' for 40,000 require the use of an outlet choke plate at altitude 0 to 2,000 ft (0 to 610M).
Failure to use an outlet choke when required may result in flame disturbance or flame sense lockout.
3. Vent sizing for Canadian installations over 4500 ft (1370m) above sea level are subject to acceptance by the local authorities having jurisdiction.
4. NA --- Not allowed; pressure switch will not close, or flame disturbance may result.
5. Do not use pipe size greater than those specified in table or incomplete combustion, flame disturbance, or flame sense lockout may occur.
6. Size both the combustion ---air and vent pipe independently, then use the larger diameter for both pipes.
7. Assume the two 45_ elbows equal one 90_ elbow. Wide radius elbows are desirable and may be required in some cases.
8. Elbows and pipe sections within the furnace casing and at the vent termination should not be included in vent length or elbow count.
9. The minimum pipe length is 5 ft. (1.5 M) for all applications.
10. Use 3 ---in. (76 mm) diameter vent termination kit for installations requiring 4 ---in. (102 mm) diameter pipe.
