PROVING SWITCH ADJUSTMENTS

After proper air flow is established, the pressure switch adjustment is made by turning pressure switch adjustment screw clockwise (See Figure 10) until burner operation stops. Turn the adjustment screw counter clockwise 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!

THERMOSTAT HEAT ANTICIPATOR ADJUSTMENT

After venting kit installation and checkout, check the amperage current draw through the thermostat circuit and adjust the thermostat anticipator accordingly.

POST PURGE TIMER ADJUSTMENT

To adjust the post purge time, refer to Figures 11 & 12.

For timer that looks like Figure 11: 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 12: 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.

WIRING

CAUTION: Disconnect electrical power when wiring power venter.

NOTE: If using this control kit with an electronic thermostat you need an RJR-5 isolation relay. 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 insure 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. Route the venter motor and control wiring with an appropriate wiring method. Refer to the Wiring Diagram A.
