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.

ADJUSTMENTS

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 turn counterclockwise to ensure proper switch setting. (See
Figure 6)

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 7) Typical post
purge time should be between 3 to 5 min.

SYSTEM CONTROL CHECK OUT PROCEDURES

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

1. Thermostat calls for heat.

2. Relay is energized, post purge timer is energized, and venter
motor starts.

3. Pressure switch closes and burner starts.

4. Thermostat is satisfied, relay is de-energized, burner stops and post purge timer operates venter
motor for approximately 3 to 5 minutes.

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 and repeat.

MAINTENANCE

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.

TROUBLE SHOOTING HINTS

Figure 6

Figure 7

1. Main burner does not fire when thermostat calls for heat with venter operating.
a. Check pressure switch adjustment.
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.
