VENT TERMINATION – DIRECT VENT – ALL MODELS

WHEN LOCATING THE TERMINALS ON A SIDEWALL, THE FOLLOWING SPECIFICATIONS PERTAINING TO TERMINAL LOCATION MUST BE FOLLOWED.

1.The intake vent terminal and the exhaust vent terminal must terminate on the same exterior wall and must be located at a minimum of 24" (61cm) from the vertical centerline of the exhaust vent terminal (see Figure 9).

In colder climates increasing the 24" (61cm) minimum will reduce possibility of frost over from side winds blowing exhaust vapors to the air intake of the direct vent.

2.The horizontal centerline of the intake vent terminal may not be located lower than the horizontal centerline of the exhaust vent terminal
