The starting collar base is the only place that the Z Vent will be installed with the Z Vent Sealant. All the other sections have built-in gaskets that only require a light coating of Versalube Silicone Compound.
Planning, measuring and orienting the Z Vent (a dry fit)
The venting requires a 1/4" per foot rise, and the small pieces of rope helped hold the pipe temporarily in the approximate position. Also, doing this solo probably prevented any helper from any harm!
Cutting the Z Vent was relatively easy. After measuring "twice"--you wrap a sheet of paper around the pipe to keep it even, then just trace the top of the paper with a perm pen marker. (cut male end ONLY, the female end contains the gasket)
You can hacksaw the metal, but I used a metal cut off wheel. After cutting, you need to file the cutting edge to insure it is smooth and even. My round chainsaw file helped clean up the round inside portion.

You may have to make one or two cuts depending on your unique setting.

You should follow the manufacturer's directions and comply with all local codes. Your level of expertise and educational credentials/certifications may vary. When you are not confident, why not let a professional HVAC person do the installation?

The WM Boiler manual states to "select a vent pipe manufacturer and obtain all vent components needed..." and "you must use the vent starter made by the vent manufacturer."

The Z Vent has a band on the female end that tightens the sections together. The screw has to be torqued to specs.
I used my torque screwdriver with a hex head nut driver fitting to achieve the specs. The instructions state a range: 40 in/lbs to 50 in/lbs.
