ULTRAFORCE COMMERCIAL GAS WATER HEATER
SUF 120 thru 400 SERVICE HANDBOOK
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
