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-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.

2. Fasten the flexible conduit from the SWG Venter into the conduit
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.

1. Pierce a 5/8" dia. hole into the vent pipe near the appliance outlet.
Remove one of the securing nuts from the shaft of the safety switch.
(See Figure 4) Tighten the other securing nut onto the pipe as far as
possible.

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- 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.

3. For remote mounted CK-61 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

Oil Fired System: Single Unit Wiring

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.
