RESSURE WITCH ENSING
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.

ROVING WITCH DJUSTMENTS
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!

OST URGE IMING
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
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.
