SYSTEM CONTROL KIT

Model: CK-20F and CK-20FG

(NOTE: CK-20FG units are designed for the Flame Guard units built by

American Water Heater. All other manufacturers use CK-20F)

Designed for use with the SWG Series Power Venter for controlling a 30-

millivolt controlled Natural or L.P. Gas appliances with a pressure tap port

in the Gas Valve. This kit may also be used with the PVG series sidewall

MOUNTING JUNCTION BOX The junction box can be mounted at the venter or remotely mounted away from the venter. (See Figure 1 & 2) 1. Remove one of the knockouts from the side of the junction box. Install the flexible conduit connector onto the CK-20F junction box and secure with fastening nut. If remote mounting the CK-20F junction box, mount the flexible conduit connector onto a 2" x 4" installer supplied junction box. 2. Fasten the flexible conduit from the SWG Venter into the conduit connector.

. Mount the two spillage switches onto the draft hood and connect inside terminals of switches with jumper wire. Connect outside terminals to lead wires which are connected to the thermocouple junction block. (See Diagram A) 4. Route jacketed lead wires or accepted wiring enclosure on the outside of the water heater enclosure. Secure them to the enclosure with an accepted hold down tab. Keep wiring away from any HOT surface area.

TROUBLE SHOOTING HINTS 1. Venter does not activate when thermostat calls for heat. a. Check wiring. b. Check gas pressure switch for continuity across terminals when gas valve is pressurized. c. Check gas pressure. 2. Flue gas odor: a. Check system draft. b. Check for negative pressure in building. 3. Pilot will not stay lit on water heater: a. Solder all spillage switch wire terminal connections. b. Check reset buttons on spillage switches. c. Use 12 gage wire for all spillage switch wiring. d.
