Insert the male end of the straight pipe or elbow into the flanged gasketed
end of the PVC adapter. Push the pipe or elbow into the adapter using a twisting
motion to fully insert the pipe into the gasket inside the adapter.
WARNING
Make sure pipe sections are fully inserted into the PVC adapter and/or gasketed end of Centrotherm fitting.
Insertion depth is no less than 2 inches.
Step 5: Centrotherm supplied support brackets must be used to support the pipe sections. The vent pipe sections must
be supported a minimum of every 5 feet (1.5 meters) of vertical run or every 3 feet (1 meter) of horizontal run of pipe.
Consult local codes for additional requirements. In addition, support brackets must be installed on both sides of elbows
used in the venting system.
High Efficiency Commercial Condensing Models:
For horizontal sections of flue pipe, the pipe must be installed with a slight upward slope of approximately 5/8 inch per
foot (5.6 cm per meter) toward the water heater (as recommended by Centrotherm) to allow condensate to drain into
the condensate elbow.
Residential and Commercial Power Direct Vent and Residential Power Vent Models:
To prevent condensate from accumulating in the exhaust blower, install the horizontal vent pipe with a downward slope
toward the vent terminal of 5/8 inch per foot (5.6 cm per meter) of horizontal vent pipe. An optional condensate kit is
available for residential power vent models or a tee fitting with a condensate drain loop may be used on commercial
power direct vent models to prevent condensate accumulation in the blower for long vertical runs of vent pipe. Refer to
the venting section of the Installation and Operating Instructions supplied with the water heater.
