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 1

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.

ADJUSTMENTS

Figure 8

Post Purge

Adjustment

PRESSURE SWITCH ADJUSTMENTS
With the venter air flow set and the appliance operating at

the best operating efficiency, adjust the pressure switch by
rotating the adjustment screw clockwise until the burner
shuts off, then rotate the adjustment screw
counterclockwise until the burner fires. Rotate the
adjustment screw an additional 1/4 to 1/2 turn
counterclockwise to ensure proper switch setting. (See
Figure 7)

POST PURGE TIMING ADJUSTMENT

To adjust the post purge time, rotate the timer adjustment
on the timer clockwise to increase the operation time. To
decrease the operation time, rotate the timer adjustment

counterclockwise. (See Figure 8) Typical post purge
time should be between 3 to 5 minutes. If running
burner simultaneous with venter, 1-3 minutes is
suggested.

SYSTEM CONTROL CHECK OUT PROCEDURES

1. Adjust the thermostat to call for heat and observe
the power venting system for proper operation
sequence (Repeat if necessary).

a. Thermostat calls for heat.
b. Relay is energized and venter motor starts.
c. Pressure switch closes and burner starts.

The LED light indicates power to T3. When the
pressure switch closes with a call for heat, the
LED light will come on. This indicates that the
burner should be in a burn cycle. (See Figure

8)

d. Thermostat is satisfied, burner stops and venter

motor should operate for the set post purge time.
The LED should not be on during the post purge.

2. While system is operating, disconnect power to
the venter motor. This should open the pressure
switch contacts and stop burner operation.

3. (If WMO-1 switch is installed) Allow vent system to cool. Disconnect the vent pipe between the venter inlet
and the appliance outlet. Block the vent pipe with a noncombustible material. Activate the heating system
with the main burner operating. Allow approximately 2 minutes or less for the secondary safety switch to
deactivate the burner. Reset safety switch after waiting 15 minutes for WMO-1 to cool down and repeat.

YEARLY MAINTENANCE PROCEDURE FOR POWER VENTER

1. Motor: Inspect motor once a year; the motor should rotate freely.

2. Wheel: Inspect venter wheel annually, for oil fired heating systems, clear any soot, ash or coating, which
inhibits either rotation or air flow. Remove all foreign material before operating.

3. Vent System: Inspect all vent pipe connections annually for looseness and for evidence of flue gas leakage.
Seal or tighten pipe connections if necessary.

4. Lubricate motor with SWG Superlube with 6 drops in each oil port hole annually.

TROUBLE SHOOTING HINTS

1. Main burner does not fire when thermostat calls for heat with venter operating.
a. Check pressure switch adjustment. (LED should be lit when there is voltage from T1 – T2 and the

pressure switch is closed.)
b. Check fuel flow.
c. Check wiring connections between pressure switch and burner.
d. Check pressure switch for continuity across terminals, during venter operation.

2. Venter does not activate when thermostat calls for heat.
a. Jump wire the terminals L1 and M to ensure motor operation.
b. Check wiring.

3. Flue gas odor.
a. Check system draft.
b. Check post purge venting time.
c. Check for negative pressure in building.

4. Power venter cycling.
a. Check voltage between T1 and T2 and refer to Wiring Check-Out Standard Set-up (see below).
b. Use resistor between T1 (120V) and T2 for bleed voltage.
