OUNTING JUNCTION BOX

The junction box can be mounted at the venter or remotely mounted away from
the venter. (See Figure 1 & Figure 2)

1. Remove one of the knockouts from the side of the junction box where the
pressure switch is mounted. Install the flexible conduit connector onto the
CK-43 junction box and secure with fastening nut. If remote mounting the
CK-43 junction box, mount the flexible conduit connector onto a 2" x 4"
installer supplied junction box.

2. Fasten the flexible conduit from the SWG Venter into the conduit
connector. Mount the CK-43 junction box or installer supplied
junction box onto the wall or floor joist without straining the
flexible conduit. Fasten the CK-43 junction box through the four
dimpled locations on the base of the box. (See Figure 3)

RESSURE SWITCH SENSING TUBE INSTALLATION

1. Attach the 1/4 inch tubing connector to the pressure tube on the
SWG Venter. (See Figure 3)

Figure 1

2. Connect the supplied 1/4" aluminum tubing to the tubing
connector. Route the tubing to the CK-43 junction box and
connect the tubing to the pressure switch. When routing the
tubing, avoid kinking the tubing by bending the tubing too
sharply.

For remote mounted CK-43 Junction Box, use a 1/4" OD copper,
aluminum or plastic tubing and route the tubing to avoid contact with
any heat source.

the collar together.

3. Hold the collar against the side of the flue in the exact position it
is to be installed (shown by dotted lines) and mark the outline
of the collar on the flue.

4. Cut a hole in the flue about 1/2" inside of this outline.

5. Make a series of cuts about 1/2" apart from the edge of this hole
to the outline marks.
