MOUNTING JUNCTION BOX

The junction box can be mounted at the venter or
remotely mounted away from the venter.
(See Figure 1 & Figure 2)

NOTE: Make sure pressure switch is in a vertical
position. The pressure switch will not sense properly in a
horizontal position.

Remove one of the knockouts from the side of the 1.
junction box where the pressure switch is mounted.
Install the flexible conduit connector onto the CK­41F junction box and secure with fastening nut. If
remote mounting the CK-41F junction box, mount
the flexible conduit connector onto a 2" x 4"
installer supplied junction box.

Fasten the flexible conduit from the SWG Venter 2.
into the conduit connector. Mount the CK-41F
junction box or installer supplied junction box onto
the wall or floor joist without straining the flexible
conduit. Fasten the CK-41F 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" tubing connector to the pressure tube

on the SWG Venter. (See Figure 3)

1

Connect the supplied 2.

⁄4" aluminum tubing to the
tubing connector. Route the tubing to the CK-41F
junction box and connect the tubing to the pressure
switch. When routing the tubing, avoid kinking the
tubing by bending the tubing too sharply.

1

For remote mounted CK-41F Junction Box, use a

⁄4" OD
copper, aluminum or plastic tubing and route the tubing
to avoid contact with any heat source. A maximum of

1

80 feet of

⁄4" tubing can be used with the SWG Series

power venter.

PROVING SWITCH ADJUSTMENTS

After proper air flow is established, the pressure switch
adjustment is made by turning the pressure switch
adjustment screw clockwise (See Figure 4) until burner
operation stops. Turn the adjustment screw counter
clockwise until burner ignites. Turn the adjustment screw

1

an additional

⁄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

Figure 4

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 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 one wiring or equivalent
methods. Route the venter motor and control wiring with an appropriate wiring method. Refer to Wiring
Diagrams.

LOW VOLTAGE WIRING INSTRUCTIONS FOR BOILERS AND WARM AIR FURNACES

With boilers, locate terminal on spark ignition module or gas valve, (if standing pilot) which would 1.
normally be 24 volts hot on a call for heat. With spark ignition systems, this terminal could be TH-W or
24 V 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-41F.3.
With boilers, connect T3 on CK-41F to hot side of gas valve (if standing pilot) or to terminal TH-W or 24 4.

V, 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-41F to terminal W in furnace junction box.5.
Connect T2 on CK-41F to a 24 volt neutral on transformer or where convenient, or to the C terminal in the 6.

furnace fan center.

LINE VOLTAGE WIRING INSTRUCTIONS

Connect 120 volts hot power source wire to terminal L1 on CK-41F.1.
Connect 120 volts neutral power source wire and white wire from venter motor to terminal N on the 2.

CK - 41F.
Connect black wire from venter motor to terminal M on the CK-41F.3.
