PRESSURE SWITCH SENSING TUBE INSTALLATION
1. Attach the 1/4 inch tubing connector to the pressure tube on the SWG Venter.
(See Figure 11)
2. Connect the supplied 1/4" aluminum tubing to the tubing connector. Route the
tubing to the CK-43F 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-43F Junction Box, use a 1/4" OD copper, aluminum or
plastic tubing and route the tubing to avoid contact with any heat source.
WIRING
WARNING: Disconnect power supply before installation to prevent personal
injury or death from electrical shock and equipment damage.
Wire the power venter motor and controls in accordance with the National Electric Code and applicable local codes.
CAUTION: Unit must be grounded. Check ground circuit to make certain that the unit has been properly grounded.
CAUTION: All parts of this product that are capable of conducting electrical current are grounded. If grounding wires,
screws, straps, clips, nuts, or washers used to complete a path to ground are removed for service, they must be returned
to their original position and properly fastened. The wiring should be protected by an over-current circuit device rated at 15
amperes.
CAUTION: Power venter wiring must not come in contact with any heat source. All line voltage and safety control circuits,
between the power venter and the appliance, MUST be wired in accordance with the National Electrical Code for Class 1
wiring or equivalent.
Refer to Diagram C for guidance in wiring the Power Venter and Control Kit to the appliance.
SYSTEM CONTROL CHECK OUT PROCEDURES
1. Adjust the thermostat to call for heat and observe the power venting system for proper operation sequence (Repeat if
necessary.)
a. Thermostat calls for heat.
b. Relay in Control Kit is energized and Power Venter motor starts.
c. Air pressure switch closes and ignition sequence starts.
d. Thermostat is satisfied, the appliance burner stops.
e. Power Venter continues to run.
f. Power Venter stops after the post purge cycle.
2. After verifying the correct operation of the system as stated above, repeat the procedure. While the appliance is
operating, disconnect power to the Power Venter motor. As the venter motor slows, the air pressure switch contacts
will open and stop the appliance burner operation. This simulates a venter failure and tests the fan proving switch and
wiring.
