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.

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.
