vent sample port

in THE MAIN WALL
I just got done yesterday cutting the basement wall and gluing the CPVC together for the air intake and vent for my new boiler.

I realized, in retrospect, that I didn't install a port on the vent piping to sample exhause gases.  Is this a big deal?  Can they be sampled from outside?  Alternately, is there a specific fitting for 2" CPVC (sch 80, the dark gray stuff) that I could retrofit in with a union fitting that would allow indoor sampling?



Thanks gang!

    Hole and Plug

    If you are needing a hole for a combustion analyzer probe, I just drill and tap threads in the proper location for sampling and then just use a SS bolt or plug.  This may be more of an issue after the fact since you now have the chance of getting debris in the closed system.  Mike

    thanks

    That sounds good - it's all glued together - don't want to get plastic shards in the vent, if I can avoid it.

     - or maybe I'll wait for the professional that I plan to bring in to finish the gas hook-up and initiate the system.
