VENT EXAMPLES FOR SINGLE FLUE
Max Vent Run - 40 ft. Equivalent With Three (3) 90° Elbows
Special Note: The vent terminal 90° elbow and rst 90° el-
bowoffbackoftheheater,whenwithin6”(15.2cm),donot
contribute 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 in-
stalled every 3 feet. No “sags” in horizontal vent runs; water will
settle in the pipe.
When installing a single ue horizontal, the minimum vent length
protruding from the outside wall is 6” (15.2 cm). See Figure 23.
Minimum vent from the rear of the unit is 12”.
Note: Horizontal discharge 90° elbow must be pointed down-
ward. See Figure 23. 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 hard-
ware store. Schedule 40 PVC pipe should be used and cemented.
Flex Kit and Horizontal Vent Adaptor Kit are available from Em-
pire Comfort Systems, Inc.
