DO NOT DESTROY

THESE INSTRUCTIONS MUST REMAIN WITH EQUIPMENT

MOUNTING JUNCTION BOX

Figure 1

Figure 2

The junction box can be mounted at the venter or remotely mounted away from the venter. (See Figure 1 & 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-66 & 67 Junction Box and secure with fastening nut. If remote mounting the CK-66 or 67
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-66 & 67 Junction box or
installer supplied junction box onto the wall or floor joist without straining the flexible conduit. Fasten the CK-66 or 67
Junction Box through the four dimpled locations on the base of the box. (See Figure 3)

OIL FIRED SECONDARY SAFETY SWITCH (CK-67 ONLY)

Installation of a SECONDARY SAFETY SWITCH 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 pipe of the safety switch.
Tighten the other securing nut onto the pipe as far as possible. (See
Figure 4)

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.

WIRING

1. Wire the venter motor and controls in accordance with the National
Electrical Code, manufacturer's recommendations and/or applicable
local codes. UNIT MUST BE GROUNDED. Check ground circuit to
make certain that the unit has been properly grounded. The wiring
should be protected by an over current circuit device rated at 15
amperes. CAUTION must be taken to ensure that the wiring does not
come into contact with any heat source. All line voltage and safety
control circuits, between the venter and the appliance, MUST be wired in accordance with the National Electrical Code for
Class I wiring or equivalent methods.

2. Route the venter motor and control wiring with an appropriate wiring method. Refer to the Wiring Diagrams A and B.

PRESSURE SWITCH SENSING TUBE INSTALLATION

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-66 or 67 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-66 or 67 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.
