Page 2: Installation Safety Instructions
CONTROL KITS 1. For 24 volt control systems (intermittent pilot ignition): CK-41 control kit with the following components: Junction box with mounted pressure switch and relay base, 24 volt relay for controlling power venter motor, 1 ft. length of 0.25" aluminum tubing, 0.25"... - Page 3 2. Safety inspection of a venting system should be performed before and after installing a power venting system on an existing or new appliance. Procedures to follow are those recommended by the National Fuel Gas Code, A.N.S.I.Z223.1, or refer to General Installation Inspection section of this manual. 3.
- Page 4 ROCEDURE FOR CALCULATING TOTAL EQUIVALENT PIPE LENGTH IN FEET 1. Calculate the total equivalent feet for each type of fitting used in the venting system from the chart below. 2. Calculate the total amount of feet for the straight lengths of vent pipe. 3.

Figure 3 Figure 4 Diagram A 3. After determining the location of the venting system termination point (See Diagram A), cut a square hole through the wall 1" larger than the outer pipe diameter of the power venter. Mount the power venter through the wall, keeping the outer pipe centered in the hole. - Page 6 If mounting venting system near combustible materials, refer to Diagram B for allowable installation clearances. Clearances are based on an installation using single wall galvanized steel vent pipe. For metal thickness of galvanized steel pipe connectors, refer to NFPA 211 or NFPA 54 Standards for guidelines. If manufactured double wall vent pipe is required or used for the installation, clearance should be based on the vent pipes rated clearance.

CLASS B AND CLASS L DOUBLE WALL VENT PIPE INSTALLATION (Follow vent pipe manufacturer's listed or recommended clearances from combus- tible material.) 5. Using a hand crimper or a like device, crimp the inner pipe of the SWG power venter approximately 1" long. (See Figure 8) 6. - Page 8 Install the GSK-3 spillage switch on the draft hood with the self- tapping sheet metal screw supplied. The thermal element disc should hang just below the draft hood relief opening. (See Figure 10) 8. Run the two (2) yellow wires from the break in the top of the wiring harness into the spillage switch through the plastic bushing opening and connect to the switch terminals.

Page 12: Pressure Switch Adjustment
PRESSURE SWITCH ADJUSTMENT Important: Both the CK-41 and CK-81 power vent control systems have a pressure switch which must be properly set before the water heater can be started. The pressure switches are set so that the contacts will not close until properly set by the installer. Failure to carefully follow the procedure below for setting the pressure switch will either prevent the water heater from operating properly of defeat the safety feature of the control which could allow a... -
