VENT PIPE ASSEMBLY
There are three parts of the vent pipe assembly that connect the water

in the VENT PIPE PREPARATION section of this manual. These PVC
parts should be assembled with ASTM D-2564 grade cement.

(Condensate U-Assembly) is shown inFigure 16.However this

see Figure 16. Disassemble the parts and cement back together
using the alignment marks. After the cement dries, attach the
assembly to the blower and the water heater exhaust using the
supplied rubber boots and hose clamps.
A condensate trap is incorporated in the bottom of this vent pipe assembly.
