Horizontal And Vertical Direct Vent Lengths

This Powered Direct Vent Gas Water Heater comes with one (1) direct vent kit. The venting system supplied with this

water heater is a coaxial (pipe within a pipe) design with the flue discharge tube on the inside and combustion air supply

on the outside. Optional direct vent components are available that can extend the horizontal length and/or vertical height

of the direct vent system to the maximum distances listed in the table below. This water heater must be installed using

the supplied or optional listed components without modifications. Reference the Venting Component Tables listed in the

Installation (Direct Vent System Installation) for the various system components.

Note: The supplied horizontal vent terminal may be used to vent through outside walls up to 24 in. (61 cm) thick.

Maximum Venting Distances (Horizontal, Vertical, or Combined)

Number of 90° Elbows Maximum distance of straight pipe (excluding vent terminal) to exterior wall

0 22 ft. 9 in. (7 m)

1 19 ft. 6 in. (6 m)

2 16 ft. 3 in. (5 m)

3 13 ft. (4 m)

Note: Each 45° elbow reduces the maximum venting distance by 19 1/2 in. (50 cm).
