VENT PIPE TERMINATION
NOTE: Before installing the Sealed Shot power vent, it is
recommended that the location of the vent pipe
terminations (intake vent terminal and exhaust vent
terminal) be determined.
WARNING
THIS UNIT CONSISTS OF AN INTAKE VENT TERMINAL AND
AN EXHAUST VENT TERMINAL. THE INTAKE VENT TERMINAL
CONSISTS OF A 45 DEGREE ELBOW WITH A DIVERTER
PLATE AND SCREEN ADAPTER. SEE FIG. 3.
IT IS VERY CRUCIAL THAT THE INTAKE VENT TERMINAL HAS
THE DIVERTER PLATE AND SCREEN ADAPTER ORIENTED
CORRECTLY AS SHOWN IN FIG. 3. IF THE DIVERTER PLATE
IS NOT LOCATED AS SHOWN, GO TO THE NEAREST DEALER
AND HAVE THE INTAKE VENT TERMINAL REPLACED.
FIGURE 3
THE EXHAUST VENT TERMINAL CONSIST OF A 45 DEGREE
ELBOW WITH A MESH SCREEN PRESSED INTO THE ELBOW.
SEE FIG 3.
WARNING
IF THE INTAKE VENT TERMINAL AND EXHAUST VENT
TERMINAL DO NOT RESEMBLE THE DIAGRAMS SHOWN IN
FIG. 3, THEN GO TO THE NEAREST DEALER AND HAVE THEM
REPLACE THE VENT TERMINALS WITH THE CORRECT
ONES.
VENT TERMINAL INSTALLATIONS
IMPORTANT
The vent system must terminate so that proper clearances are
maintained as cited in local codes or the latest edition of the
National Fuel Gas Code, ANSI Z223.1, 7.3.4e, and 7.8a, b as
follows.
1.
The intake and exhaust vent terminals of a mechanical vent
system shall be not less than 7 feet above grade when located
adjacent to public walkways. (fig. 4)
2.
The venting system shall terminate at least 3 feet above any
forced air inlet located within 10 feet. (fig. 4)
3.
The venting system shall terminate at least 9 inches below,
9 inches horizontally from or 9 inches above any door,
window, or gravity air inlet into building.
4.
The manufacturer also recommends the vent system
terminations not to be installed closer than 3 feet from an
inside corner of an L shaped structure, and not less than 1
foot above grade. The vent shall terminate a minimum 12"
above expected snowfall level to prevent blockage of vent
termination.
5.
The vent termination shall not be mounted directly above or
within 3 feet horizontally from an oil tank vent or gas meter
to avoid potential freeze-up from condensation.
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
VENT HOOD INSTALLATIONS, and with the National Fuel Gas
Code and local codes.
IMPORTANT
Plan the layout of the vent system backwards from the vent
termination to the appliance. Take into consideration that an elbow
will be necessary to make the first vent pipe connection to the
blower outlet.
WARNING
USE ONLY THE VENT HOOD SUPPLIED WITH THIS KIT.
TERMINATION OF A VENT SYSTEM WITH A DEVICE OTHER
THAN THE SUPPLIED VENT HOOD WILL AFFECT SYSTEM
PERFORMANCE AND RESULT IN A SAFETY HAZARD.
SIDE WALL VENT TERMINAL INSTALLATION
IMPORTANT
THIS UNIT CONSISTS OF TWO VENT TERMINALS - AN INTAKE
VENT TERMINAL AND AN EXHAUST VENT TERMINAL. THE
INTAKE VENT TERMINAL IS A 45 DEGREE PVC ELBOW WITH
A DIVERTER PLATE AND SCREEN ADAPTER WHILE THE
EXHAUST VENT TERMINAL IS A 45 DEGREE ELBOW WITH A
MESH WIRE SCREEN.
IMPORTANT
WHEN TERMINATING 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.
2.
The vertical centerline of the intake vent terminal must be
located at a minimum of 16 inches from the vertical centerline
of the exhaust vent terminal.
3.
The horizontal centerline of the intake vent terminal may not
be located lower than 4 inches below the horizontal centerline
of the exhaust vent terminal.
The specifications are displayed in fig. 5.
