MOUNTING JUNCTION BOX:

The junction box can be mounted at the venter or remotely
mounted away from the venter. (See Fig. 1 & Fig. 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-65 junction box
and secure with fastening nut. If remote mounting the CK­65 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-65 junction box or installer supplied junction
box onto the wall or floor joist without straining the flexible conduit.
Fasten the CK-65 junction box through the four dimpled locations on
the base of the box. (See Fig. 3)

OIL FIRED SECONDARY SAFETY SWITCH

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

Fig

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

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 Fig. 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 Fig. 3)

2. Connect the supplied 1/4" aluminum tubing to the tubing
connector. Route the tubing to the CK-65 junction box and
connect the tubing to the pressure switch. When routing the
tubing, avoid kinking the tubing by bending the tubing too
sharply.

For remote mounted CK-65 Junction Box, use a 1/4" OD copper,
aluminum or plastic tubing and route the tubing to avoid contact
with any heat source.

PROVING SWITCH ADJUSTMENTS:

After proper air flow is established, the pressure switch adjustment is
made by turning the pressure switch adjustment screw clockwise
(See Fig. 6) until burner operation stops. Turn the adjustment screw
counterclockwise until burner ignites. Turn the adjustment screw an
additional 1/4 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 in a hazardous condition and
bodily harm!

POST PURGE TIMING ADJUSTMENT:

To adjust the post purge time, rotate the timer adjustment on the timer
counterclockwise to increase the operation time. To decrease the operation
time, rotate the timer adjustment clockwise. (See Fig. 7) Typical post purge

Figure 7

time should be between 3 to 5 min.

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. Refer to wiring diagrams A and B for typical wiring
installations.
