1.Pull the 3 1/8” corrugated pipe toward the water heater and leave some length over the water heater’s center for bending.
2.Pull the 6” corrugated pipe toward the water heater and leave it 1” shorter than 3 1/8” pipe.
3.Make sure there are two springs evenly spaced at the bend in the pipe.
4.Use metal hangers to keep vent pipe level or with a slope upward from the heater to terminal.
