Product Q&A

Verified Reply- SupplyHouse StaffTerminating the venting through a sidewall is recommended for the direct-vent system. Running the exhaust vent and the intake pipe parallel is recommended. Terminating the exhaust and intake on the same wall/surface is recommended. Terminating in the same pressure zone allows for pressure balancing, which prevents nuisance shutdowns.

Verified Reply- SupplyHouse StaffYour Takagai unit must vent into the correct diameter category 3 stainless steel venting. We recommend checking your existing venting to ensure compliance with the manufacturers specifications in the Takagi installation manual.

It will slide inside 3" PVC pipe
Can't give you an exact dimension, (it is installed and glued up) but it is in the 3" range. I have it installed sliding into a schedule 40 PVC 3" pipe. Hope that helps. privacy policy (NEW!) here.
