WIRING
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 overcurrent 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 A and B.
LOW VOLTAGE WIRING INSTRUCTIONS FOR BOILERS AND WARM AIR FURNACES
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, 24 V, THS or
T1 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-91F.
4. With boilers, connect T3 on CK-91F to hot side of gas valve (if standing pilot) or to terminal TH-W, 24 V,
THS or T1 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-91F to terminal W in furnace junction box.
6. Connect T2 on CK-91F to a 24 volt neutral where convenient.
LINE VOLTAGE WIRING INSTRUCTIONS
1. Connect 120 volts neutral hot power source wire to terminal L1 on CK-91F.
2. Connect 120 volts neutral power source wire and white wire from venter motor to terminal N on the
CK-91F.
3. Connect black wire from venter motor to terminal M on the CK-91F.
Refer to the SWG Venter installation instructions for setting system airfl ow.
