INSTALLATION INSTRUCTIONS
Designed for use with the SWG Series Power Venter for controlling Natural Gas or L.P. Gas
appliances.
Items included in Kit:
1) Junction box with mounted pressure switch and post purge timer
1) Fan control gas pressure switch
1) 2 ft. length of 1/4 inch aluminum tubing
2) Flexible conduit connector
1) 1/4 inch tubing connector
MOUNTING JUNCTION BOX:
The junction box can be mounted at the venter or remotely mounted away from the venter. (See Fig. 1
& Fig. 2)
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 CK40F junction box and secure with fastening nut. If
remote mounting the CK-40F 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-40F
junction box or installer supplied junction box onto
the wall or floor joist without straining the flexible
conduit. Fasten the CK-40F junction box through
the four dimpled locations on the base of the box.
(See Fig. 3)

PRESSURE SWITCH SENSING TUBE INSTALLATION:
1. Attach the 1/4 inch tubing connector to the pressure tube on the SWG Venter. (See Fig. 3)
2. Connect the supplied 1/4" aluminum tubing to the tubing connector. Route the tubing to the CK40F 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-40F Junction Box, use a 1/4" OD copper, aluminum or plastic tubing and
route the tubing to avoid contact with any heat source.
PROVING SWITCH ADJUSTMENTS:
After proper air flow is established, the pressure switch
Figure 4
adjustment is made by turning the pressure switch
adjustment screw clockwise (See Fig. 4) until burner
operation stops. Turn the adjustment screw
counterclockwise until burner ignites. Turn the adjustment
screw an additional 1/4 to 3/4 turn counterclockwise to
ensure adequate switch adjustment.
Warning: Failure to properly adjust the pressure switch
as specified above could lead to improper operation of
the pressure switch which will result in a hazardous
condition and bodily harm!
THERMOSTAT HEAT ANTICIPATOR ADJUSTMENT:
After venting kit installation and checkout, check the amperage current draw through the thermostat
circuit and adjust the thermostat anticipator accordingly.

WIRING INSTRUCTIONS
CAUTION: DISCONNECT ELECTRICAL POWER WHEN WIRING POWER VENTER
Wire the venter motor and controls in accordance with the National Electrical Code, manufacturer's
recommendations and/or applicable local codes. UNITS MUST BE GROUNDED. Check ground
circuit to make certain that the unit has been properly grounded. The wiring should be protected by an
overcurrent 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
one wiring or equivalent methods. Route the venter motor and control wiring with an appropriate wiring
method. Refer to Wiring Diagrams A and B.
LOW VOLTAGE WIRING INSTRUCTIONS FOR BOILERS AND WARM AIR FURNACES:
SYSTEM CONTROL CHECK OUT PROCEDURES:
1. For furnaces or boilers, 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.
d. Thermostat is satisfied, the burner stops.
e. This starts the post purge cycle. Purge time 1 to 2 min.
2. While system is operating, disconnect power to the venter motor. This should open the pressure
switch contacts and stop burner operation.
1. With boilers, locate terminal on spark ignition module or gas valve (if standing pilot) which would
normally be 24 volts hot on a call for heat. With spark ignition systems, this terminal could be THW, 24 V, THS or T1 depending on the spark ignition control.
With warm air furnaces, locate terminal W in furnace junction box.
2. Remove wire from this terminal and reroute to T1 on CK-40F.
3. With boilers, connect T3 on CK-40F to hot side of gas valve (if standing pilot) or to terminal TH-W,
24 V, THS or T1 if spark ignition.
NOTE: Remember, the correct terminal is the one that would normally be hot on a call for heat.
With warm air furnaces, connect T3 on CK-40F to terminal W in furnace junction box.
4. Connect T2 on CK-40F to a 24 volt neutral where convenient.
LINE VOLTAGE WIRING INSTRUCTIONS:
1. Connect 120 volts hot power source wire to terminal L1 on CK-40F.
2. Connect 120 volts neutral power source wire and white wire from venter motor to terminal N on
the CK-40F.
3. Connect black wire from venter motor to terminal M on the CK-40F.
REFER TO THE SWG VENTER INSTALLATION INSTRUCTIONS FOR SETTING SYSTEM AIR FLOW.
TROUBLE SHOOTING HINTS
1. Venter does not activate when thermostat calls for heat.
a. Check wiring.
b. Check gas pressure switch for continuity across terminals when gas valve is pressurized.
c. Check gas pressure.
2. Flue gas odor:
a. Check system draft.
b. Check for negative pressure in building.
