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-61 Junction Box and secure with fastening nut. If remote
mounting the CK-61 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-61 Junction box or installer supplied junction
box onto the wall or floor joist without straining the flexible conduit.
Fasten the CK- 61 Junction Box through the four dimpled locations on
the base of the box. (See Figure 3)

(WMO-1)
Installation of a SECONDARY SAFETY SWITCH (WMO-1) is
recommended for detecting flue gas spillage from a blocked flue system
and/or inadequate draft.
1. Pierce a 5/8" dia. hole into the vent pipe near the appliance outlet.
Remove one of the securing nuts from the shaft of the safety switch.
(See Figure 4) Tighten the other securing nut onto the pipe as far as
possible.
2. Insert the threaded pipe end into the pierced hole, then install the
securing nut, which was removed in Step 1, and tighten securely (See
Figure 5)
3. Wire safety switch in series into one side of the burner circuit. Refer to
Unit Wiring Instructions.
CAUTION:
If for any reason the system has shut down during
operation, the cause of the system failure should be investigated
and corrected before resetting the safety switch and restarting the
system.

NSTALLATION
1. Attach the 1/4 inch tubing connector to the pressure tube on the SWG
Venter. (See Figure 3)
2. Connect the supplied 1/4" aluminum tubing to the tubing connector.
Route the tubing to the CK- 61 Junction Box and connect the tubing to
the pressure switch. When routing the tubing avoid kinking the tubing by
bending the tubing too sharply.
3. For remote mounted CK-61 Junction Box, use a 1/4" OD copper,
aluminum or plastic tubing and route the tubing to avoid contact with any
heat source.
Refer to the SWG Venter installation instructions for setting system airflow.
