2.60K inducer outlet restrictor
Inducer Outlet Restrictor disk (PN 1185623; 1.25−in (32−mm) dia.) available through FAST Parts and is required for no greater than 5−ft (1.5−m)TEVL
in downflow and horizontal orientations only. Required for installations from 0 to 2000 ft. (0 to 610 M) above sea level.
3.100K and 120K inducer outlet restrictor
Inducer Outlet Restrictor disk (PN 1188589; 1.50−in (38−mm) dia.) available through FAST Parts and is required for no greater than 5−ft
(1.5−m) TEVL in downflow and horizontal orientations only. Required for installations from 0 to 2000 ft. (0 to 610 M) above sea level.

NOTES:
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 switch will not close, or flame disturbance may result.
3. Not all furnace families include 140,000 BTUH input models.
4. Vent sizing for Canadian installation over 4500 ft. (1370 m) above sea level are subject to acceptance by local authorities having
jurisdiction.
5. Size both the combustion air and vent pipe independently, then use the larger size for both pipes.
6. Assume two 45° degree elbows equal one 90° degree elbow. Wide radius elbows are desirable and may be required in some cases.
7. Elbow and pipe sections within the furnace casing and at the vent termination should not be included in vent length or elbow count.
8. The minimum pipe length is 5 (1.5) linear feet (meters) for all applications.
9. Use 3−in (76 mm) diameter vent termination kit for installations requiring a 4−in (102 mm) diameter pipe.
