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)

Figure 1

Figure 2

Figure 3

WARNING: Switch connection channel must be mounted horizontally,
unless specified differently by the appliance manufacturer.

CAUTION: Disconnect electrical power supply to the appliance when wiring the
blocked vent switch.

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)

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

1

adjustment screw an additional

⁄4 turn counterclockwise
to ensure proper switch setting.
(See Figure 6)

POST PURGE TIMING ADJUSTMENT

To adjust the post purge time, refer to
Figures 7 & 8.

For timer that looks like Figure 7: Rotate the timer
adjustment on the timer clockwise to increase the
operation time. To decrease the operation time,
rotate the timer adjustment counterclockwise.

For timer that looks like Figure 8: Rotate the
timer adjustment on the timer counterclockwise
to increase the operation time. To decrease
the operation time, rotate the timer adjustment
clockwise.

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

SYSTEM CONTROL CHECK OUT PROCEDURES

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

Thermostat calls for heat.a.
Relay is energized, post purge timer is energized, and venter motor starts.b.
Pressure switch closes and burner starts.c.
Thermostat is satisfied, relay is de-energized, burner stops and post purge timer operates venter motor d.

for approximately 3 to 5 minutes.

While system is operating, disconnect power to the venter motor. This should open the pressure switch 2.
contacts and stop burner operation.

(If WMO-1 switch is installed) Allow vent system to cool. Disconnect the vent pipe between the venter 3.
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

Motor:1. Inspect motor once a year; the motor should rotate freely.
Wheel: 2. 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.
Vent System:3. 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

Main burner does not fire when thermostat calls for heat with venter operating.1.

Check pressure switch adjustment.a.
Check fuel flow.b.
Check wiring connections between pressure switch and burner.c.
Check pressure switch for continuity across terminals, during venter operation.d.

Venter does not activate when thermostat calls for heat.2.

Jump wire the terminals L1 and M to ensure motor operation.a.
Check wiring.b.

Flue gas odor.3.

Check system draft.a.
Check post purge venting time.b.
Check for negative pressure in building.c.
