POWER DIRECT-VENT DESIGN
ProMax Power Direct Vent residential gas models are equipped with FVIR
technology to meet Phase III of the ANSI Z210.1 - 4.1 CSA 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 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.
