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)

Remove one of the knockouts from the side of the junction box where 1.
the pressure switch is mounted. Install the flexible conduit connector
onto the CK-61 junction box and secure with fastening nut. If remote
mounting the CK-61 junction box, mount the flexible conduit connector
onto a 2” x 4” installer supplied junction box.

Fasten the flexible conduit from the SWG Venter into the conduit 2.
connector. Mount the CK-61 junction box or installer supplied junction
box onto the wall or floor joist without straining the flexible conduit.
Fasten the CK- 61 junction box through the four dimpled locations on
the base of the box. (See Figure 3)

OIL FIRED SECONDARY SAFETY SWITCH (WMO-1)

Installation of a SECONDARY SAFETY SWITCH (WMO-1) is recommended
for detecting flue gas spillage from a blocked flue system and/or
inadequate draft.

MOUNTING IN THE VENT PIPE

SEE THE APPLIANCE MANUFACTURER’S INSTRUCTIONS FOR THE SPECIFIC LOCATION.

IF THE APPLIANCE MANUFACTURER DOES NOT SPECIFY A LOCATION, REFER TO FIGURE 5.

3

Drill or pierce a clean hole (about 1.

⁄4” diameter) in the vent pipe near

the appliance outlet. (See Figure 5)
The heat transfer tube must have the fiber gasket installed against the 2.

mounting plate before attaching the unit to the vent pipe.

3

Insert the heat transfer tube with gasket into the 3.

⁄4” diameter hole

placed in the vent pipe during step 1.
Secure the assembly to the vent pipe with a minimum of 4 sheet 4.

metal screws. The channel must be mounted horizontally, unless
specified differently by the appliance manufacturer. (See Figure 5)

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- 61 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-61 junction box, use a 3.

⁄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 E)
