Vent Examples for Single Flue

Max Vent Run - 40 ft. Equivalent With Three (3) 90° Elbows

Special Note: The vent terminal 90° elbow and ﬁrst 90° elbow off back of the heater, when within 6” (15.2 cm), do not contrib- ute to the overall vent length measurement. For each 45° elbow installed in the horizontal run, the length of the horizontal run MUST be reduced by 1.5 feet (45 cm). This does not apply if the 45° elbows are installed on the vertical part of the vent system. Reduce the length of the horizontal run 3 feet (91.4 cm) for every 90° elbow.

Note: On horizontal runs, a P.V.C. support clamp needs to be installed every 3 feet. No “sags” in horizontal vent runs; water will settle in the pipe.

When installing a single ﬂue horizontal, the minimum vent length protruding from the outside wall is 6” (15.2 cm). See Figure 17. Minimum vent from the rear of the unit is 12”.

Note: Horizontal discharge 90° elbow must be pointed downward. See Figure 18. All horizontal runs require either a 1/4” per foot rise to run condensation back to the heater, or a 1/4” per foot downward slope to run condensation away from the heater.

Note: All PVC vent run piping can be purchased at a local hardware store. Schedule 40 PVC pipe should be used and cemented. PVVK-CFA Flex Kit and PVVK-SH Horizontal Vent Adaptor Kit are available from Empire Comfort Systems, Inc.
