Direct Venting; Direct Vent Terminal Installation (Sidewall) - State Water Heaters Ultra Forcce SUF 60 120 Installation & Operation Manual

3. For horizontal the venting system, using room for combustion, the vent
terminal shall terminate 4' (122 cm) below, 4' (122 cm) horizontally from
or 1' (30.5 cm) above any door, window, or gravity air inlet into building.
4. The manufacturer also recommends the vent system terminations not
be installed closer than 3' (91cm) from an inside corner of an L shaped
structure. And not less than 1' (30.5 cm) above grade or anticipated
snow level.
5. The vent termination shall not be mounted directly above or within
3' (91cm) horizontally from an oil tank vent or gas meter to avoid potential
freeze-up from condensation.
6. The vent shall terminate a minimum of 12" (30.5 cm) above expected
snowfall level to prevent blockage of vent termination.
Plan the vent system layout so that proper clearances are maintained from
plumbing and wiring.
Vent pipes serving power vented appliances are classified by building
codes as "vent connectors". Required clearances from combustible
materials must be provided in accordance with information in this manual
under LOCATION OF HEATER and CLEARANCES, and with National Fuel
Gas Code and local Codes.
IMPORTANT
Plan the layout of the vent system backwards from the vent termination to
the appliance.
USE ONLY THE VENT TERMINALS SUPPLIED WITH THIS UNIT. TERMINATION
OF A VENT SYSTEM WITH A DEVICE OTHER THAN THE SUPPLIED VENT
TERMINATIONS WILL AFFECT SYSTEM PERFORMANCE AND RESULT IN A
SAFETY HAZARD.

DIRECT VENTING

The air intake provided on the unit contains a mesh screen (see Figure 7)
to prevent large particles from entering the unit.
3" (7.6cm) 45° PVC ELBOW WITH MESH SCREEN
WHEN THE UNIT IS TO BE SETUP AS A DIRECT VENT, THE MESH SCREEN
MUST BE REMOVED. THE INLET VENT PIPE MAY THEN BE GLUED TO THE
AIR INTAKE (see Figure 8) PROVIDED ON THE UNIT.

DIRECT VENT TERMINAL INSTALLATION
THIS UNIT CONSISTS OF TWO VENT TERMINALS - AN INTAKE VENT
TERMINAL AND AN EXHAUST VENT TERMINAL. THE INTAKE VENT
TERMINAL IS A 3" 45° PVC ELBOW (OR 3" PVC TEE FOR SUF 100 240)
WITH A MESH WIRE SCREEN AND THE EXHAUST VENT TERMINAL IS A 3"
45°PVC ELBOW WITH A MESH WIRE SCREEN.
NOTE: TO PREVENT EXHAUSTING PRODUCTS FROM CIRCULATING TO
THE AIR INTAKE IN WINDY/COLD AREAS, THE MAXIMUM PRACTICAL
DISTANCE BETWEEN THESE TWO TERMINALS IS RECOMMENDED.
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 the vent.
2. The horizontal centerline of the intake vent terminal may not be located
lower than the horizontal centerline of the exhaust vent terminal
(see Figure 9).
