INSTALLATION
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.
Remove power venter from box and inspect unit for damage. If the carton has been crushed or mutilated, 1.
check unit very carefully for damage. Rotate blower wheel to ensure 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.
Location of the termination of the venting system should be installed in accordance with the National Fuel 2.
Gas Code ANSI 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.
The exit termination of mechanical draft systems shall not be less than 7' above grade when located a.
adjacent to public walkways.
A venting system shall terminate at least 3' above any forced air inlet located within 10'.b.
The venting system of other than a direct vent appliance shall terminate at least 4' below, 4' c.
horizontally from or 1' above any door, window, or gravity air inlet into the building.
The vent termination of a direct vent appliance with an input of 50,000 BTUs per hour or less shall be d.
located at least 9" from any opening through which vented gases could enter the building. With an
input over 50,000 BTUs per hour, a 12" termination clearance shall be required.
The vent termination point shall not be installed closer than 3' from an inside corner of an L-shaped e.
structure.
The vent termination should not be mounted directly above, or within 3' horizontally from an oil tank f.
vent or gas meter.
The bottom of the vent terminal shall be located at least 12" above finished grade.g.
Prepare the CV-series power venter for installation: 3.
If the wall is thicker than 11", the CK kit tubing must be attached to the air pressure sensing tube prior to
installation, using the included tube union fitting. (See Figure 9)
Diagram A
After determining the location of the venting system termination point (See Diagram A), cut a square 4.
hole through the wall to the minimum dimensions given in Table 5, "Installation Hole Dimensions". Mount
the power venter through the wall, keeping the outer pipe centered in the hole. (See Figure 3) Fasten
the power venter to the outside wall with stainless steel or galvanized lag screws (not included) or
other appropriate fasteners. Seal the edges of the power venter mounting plate to the wall with a high
temperature silicone sealant. DO NOT enclose the spaced plates on the power venter body. This will
result in reduced cooling of the power venter body. Wood or vinyl siding should be cut so that the unit
mounts directly on the wallboard to provide a stable support. If the siding is greater than
1
⁄2" thick use a
spacer plate or board behind the power venter mounting plate. (See Figure 2)
