Field controls CK-63 User Manual

120 VAC SYSTEM CONTROL KIT

This device MUST be installed by a qualified agency* in accordance with the manufacturer’s installation instructions.

Designed for use on SWG Series
Power Vent Hoods for controlling oil
fired heating appliances with 120 VAC
controls.

The CK-63 control has the ability to
operate the oil burner motor (up to 1/3
HP) and the venter at the same time.
This allows for shorter post purge time.
This feature requires the burner to be
equipped with a delayed oil solenoid
valve, which is not supplied with this
kit.

ITEMS INCLUDED IN KIT:

1) Junction box with mounted pressure switch

solid state post purge control

1) 2 Ft. Length of ¼ inch aluminum tubing

1) ¼ inch tubing connector

1) Flexible conduit connector

1) WMO-1 Blocked Vent Switch

1) Thermostat Resistor Kit

Model: CK-63

The definition of a qualified agency is: any individual, firm, corporation or company which either in person or through a
representative is engaged in, and is responsible for, the installation and operation of oil appliances, who is experienced
in such work, familiar with all the precautions required, and has complied with all the requirements of the authority
having jurisdiction.

WARNING: Read the installation instructions carefully and completely before proceeding with the installation.

• All wiring shall be in accordance with the National Electrical Code and applicable local codes.

INSTALLATION
MOUNTING 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-63 Junction Box and secure with fastening nut. If remote
mounting the CK-63 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-63 Junction box or installer supplied junction
box onto the wall or floor joist without straining the flexible conduit.
Fasten the CK-63 Junction Box through the four dimpled locations on
the base of the box. (See Figure 3)

OIL FIRED SECONDARY SAFETY SWITCH

Installation of a SECONDARY SAFETY SWITCH is recommended for
detecting 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) (NOTE: Check to make sure WMO-1 is reset before
installing.)

Figure 2

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.

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-63 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-63 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.

WIRING INSTRUCTIONS

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.

Route the venter motor and control wiring with an appropriate wiring method. (Diagrams A through F)

NOTE: Control is factory set for 120V wiring. For 24V wiring connect the yellow mode wire to the 24V terminal.
NOTE: For 24V applications only. A resistor has been supplied for 24V power stealing thermostats. (Refer to

Figure 6A for installation of resistor) (See Wiring Diagram G for 24V gas furnace applications)

NOTE: Circuit board is polarity sensitive. Follow check-out procedures.
