NSTALLATION
CAUTION: Failure to install, maintain and/or operate the power venting system in accordance with manufacturer's
instructions will result in conditions which may produce bodily injury and/or property damage.
1. Remove power venter from box and inspect unit for damage. If the carton has been crushed or mutilated, check unit
very carefully for damage. Rotate blower wheel to insure that the motor and blower wheel rotate freely. DO NOT install
if any damage is apparent. Refer to unit sizing chart to check proper venting sizing.
2. Location of the termination of the venting system should be installed in accordance with the National Fuel Gas Code
A.N.S.I.Z223.1, manufacturer's recommendations and/or local codes which are applicable. See requirements below or
refer to installation location, Diagram A, for typical locations.
a. The exit termination of mechanical draft systems shall not be less than 7' above grade when located adjacent to
public walkways.
b. A venting system shall terminate at least 3' above any forced air inlet located within 10'.
c. The venting system of other than a direct vent appliance shall terminate at least 4' below, 4' horizontally from or 1'
above any door, window or gravity air inlet into the building.
d. The vent termination of a direct vent appliance with an input of 50,000 BTU's per hour or less, shall be located at
least 9" from any opening through which vented gases could enter the building. With an input over 50,000 BTU's
per hour, a 12" termination clearance shall be required.
e. The vent termination point shall not be installed closer than 3' from an inside corner of an L-shaped structure.
f. The vent termination should not be mounted directly above, or within 3' horizontally from an oil tank vent or gas
meter.
g. The bottom of the exterior portion of the vent terminal (excluding the riser section) shall be located at least 12"
above the surrounding finished grade or well/sill structure (see Well Installation Illustration).
3. Determine the venting system termination location (See Diagram A) and prepare the installation area: If the vent
penetration through the wall must be near or below the surrounding grade, provision must be made to protect the riser
section from standing water that could reach the level of the bottom of the riser section, such as a well structure with
adequate drainage and protection from water runoff. If a well structure is employed, adequate clearance from the
walls of the well to the riser section is required to allow for installation, inspection and cleaning of debris. It is
recommended that a sill structure and grating be employed to help prevent water and debris entry into the well (see
Well Installation Illustration). Refer to local building codes governing such structures.
4. Prepare the CV-VR series power venter for installation:
a. Extend the inner pipe of the tailpiece assembly (see Install 1, on pg 6), and using the supplied silicone sealant,
apply a bead of sealant around the end of the inner pipe of the tailpiece assembly.
b. Insert the tailpiece inner pipe into the riser inlet collar fully, and tighten the hose clamp to secure the inner pipe
into the collar (see Install 2, on pg 6).
c. Slide the tailpiece outer pipe up to the back of the riser section, and attach the outer pipe flange to the back of
the riser section using the four supplied sheet metal screws (see Install 3, on pg 6). Note: do not use the self-
drilling screws, which are for installation of the backing plates (see “Two-Piece Backing Plate Installation”
section).
