After proper air flow is established, the pressure switch
adjustment is made by turning the pressure switch
adjustment screw clockwise (See Figure 4) until burner
operation stops. Turn the adjustment screw counter
clockwise until burner ignites. Turn the adjustment
screw an additional ¼ to ¾ 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!

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. Route the venter motor and control wiring with an appropriate wiring method. Refer to
Wiring Diagrams.

1. With boilers, locate terminal on spark ignition module or gas valve, (if standing pilot) which would normally be 24 volts
hot on a call for heat. With spark ignition systems, this terminal could be TH-W or 24 V depending on the spark
ignition control.
2. With warm air furnaces, locate terminal W in furnace junction box.
3. Remove wire from this terminal and reroute to T1 on CK-41F.
4. With boilers, connect T3 on CK-41F to hot side of gas valve (if standing pilot) or to terminal TH-W or 24 V, if spark
ignition.
NOTE:
Remember, the correct terminal is the one that would normally be hot on a call for heat.
5. With warm air furnaces, connect T3 on CK-41F to terminal W in furnace junction box.
6. Connect T2 on CK-41F to a 24 volt neutral on transformer or where convenient, or to the C terminal in the furnace fan
center.
