question regarding doing the combustion analyzer, if I drill a hole into the ABS/PVC piping what should i cover the hole with? I've always just gone outside to the end of the pipe to run my tests,  On C-Vent I would just tape back over the hole with tin tape.

We used to be able to drill a hole in the plastic exhaust vent and install a plastic plug, but this method is no longer approved.

IPEX sells a testing plug and bushing kit that can be installed and used as a test port for a flue gas analyser.  You will have to install a tee in the exhaust vent to accomodate the testing plug and bushing kit.

I think all manufacturers should start incorporating this into their design.  When you install a furnace it would also be a good time to install this tee, plug and bushing.  It would make future testing much easier.

The TSSA may soon make this a mandatory requirement.
