Description for AO Smith GPDX-50

ProMax Power Direct Vent residential gas models are equipped with FVIR technology to meet Phase III of the ANSI Z21.10.1 standards for the resistance to flammable vapor ignition and resistance to lint, dust and oil accumulation tests.
The two-pipe closed-combustion system draws all make-up air from outside of the home, eliminating problems caused by insufficient indoor ventilation. The system permits combined horizontal and vertical venting and air intake runs up to 45 feet (including one 90º elbow) using 3" Schedule 40 PVC, CPVC or ABS pipe for installation versatility.

Note: GPDX-50 is supplied with 5' of 3" ABS vent pipe and must be used for the first 5' of the exhaust outlet vent system
