Ck Control Kit For Power Venter

Appliance Controls For Combustion Air Systems

Fan In A Can Control Kits Models CK-20FV, CAC-24, and CAC-120

The CK-20FV Fan In A Can control kit is designed for use with the SWG Series Power Venter for controlling 30-millivolt controlled Natural or LP Gas appliances with a pressure tap port in the Gas Valve. This kit may also be used with the PVG series sidewall Power Venters, DI series Draft Inducers, and CAS-4 Combustion Air System. The included junction box is not required when using a PVG or CAS-4.

The CAC-24 kit is designed to control more than one appliance on a system using the Field Controls CAS-4 Combustion Air System with a chimney vented 24 VAC controlled combustion appliance. The Fan In A Can control kits in the CAS-4 will operate only one appliance, therefore a CAC-24 is required for each additional appliance to be added to the same CAS-4 unit. One CAS-4 unit can handle, at max, a total combined firing rate input of up to 450,000 BTU/HR.

The CAC-120 kit is designed to control more than one appliance on a system using the Field Controls CAS-3 Combustion Air System with a chimney vented oil fired system. The controls in the CAS-3 will operate only one appliance, therefore a CAC-120 is required for each additional appliance to be added to the same CAS-3 unit. One CAS-3 unit can handle at max, a total combined firing rate input of up to 500,000 BTU/Hr.

Spillage Switches Check-Out Procedure:

  1. Allow the water heater to heat up to operating temperature, then disconnect the power to the gas pressure switch.
  2. Adjust the thermostat to call for heat with the venter inoperative. Allow approximately 2 minutes of flue gas spillage for the spillage switches to sense the spillage and disrupt the thermocouple circuit, halting the gas flow to the pilot and burner.
  3. Wait 2 to 3 minutes. Reset the spillage switches and light the pilot, then perform a second safety spillage test. (Steps 1 and 2)

Refer to the instruction manuals more details and other restrictions.
