MOUNTING CONTROL BOX

The control box must be mounted within 6' of the vent damper, and within reach of the appliance's existing
damper cable. If the control box must be mounted out of reach of the power venter's attached wiring, an
additional installer supplied junction box and wiring (with approved wiring enclosure if necessary) will be
required. (See Figures 1 & 2)

Install the flexible conduit connector onto the CK-41P control box and secure with fastening nut. If 1.
additional wiring is required, install the flexible conduit connector onto the installer supplied
junction box.

Fasten the flexible conduit from the SWG Venter into the conduit connector. Mount the CK-41P control 2.
box onto a non-heated vertical surface of the appliance or nearby wall or floor joist through the four
dimpled locations on the base of the box. NOTE: The mounted pressure switch diaphragm must be
mounted with a vertical orientation; see label on pressure switch. (See Figure 3) If required, run additional
wiring as in figure 2 and connect to CK-41P control box, if required, using the supplied flexible conduit
connector and approved connectors and anti-short bushings.
