Vent Termination - Direct Vent - All Models - State Water Heaters SUF60 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" (61 cm) from the vertical centerline of the exhaust vent
terminal (see Figure below). In colder climates increasing this separation to at least 48" (122 cm)
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.
16 Servicing should only be performed by a Qualified Service Technician
