[. . . ] Remove one of the knockouts from the side of the junction box where the pressure switch is mounted. Install the flexible conduit connector onto the CK-43F junction box and secure with fastening nut. If remote mounting the CK-43F junction box, mount the flexible conduit connector onto a 2" x 4" installer supplied junction box. Fasten the flexible conduit from the SWG Venter into the conduit connector. [. . . ] Bend the tabs formed by the series of cuts outward against the inside of the collar to make a tight joint. (See Draft Control Installation and Adjustment Section. ) DRAFT CONTROL INSTALLATION IN TYPE B VENT PIPE CAUTION: DO NOT use the supplied collar when mounting draft control to Type B Vent Pipe. Install a vent pipe reducer or increaser into the inner pipe and fasten using sheet metal screws. The opening of the Type B Vent Tee, at the draft control mounting location, should be sealed with a high temperature sealant or equivalent. DRAFT CONTROL INSTALLATION Insert the draft control into the collar or tee. The front face of the control MUST be plumb and the bearing surfaces MUST be level whether the control is on a horizontal, vertical or sloping flue pipe. (See Figure 5) Secure the control in the collar by tightening the clamping screws. If a tee is used or a collar is supplied locally, the control may be held in place by sheet metal screws. ADJUSTING THE DRAFT CONTROL WITH 4" MG1 The control MUST be adjusted to the desired draft setting by adding or removing the washer-type weights supported by the two chains on the side of the draft control. (See Figure 6) DO NOT move the weight attached directly to the gate, this is used only for balancing at the factory. Figure 5 Figure 6 Page 3 WHAT DRAFT SETTING TO USE When adjusting the control, two things are essential: 1. The burner must be operating for at least 10 minutes to obtain maximum chimney draft. An analysis of the flue gases is necessary to determine the percentage of CO2 and check for presence of CO. Refer to the appliance instructions and/or to the local gas company for the proper CO2 readings and allowable CO levels. A rule of thumb for draft setting is Figure 7 between . 01" to . 03" of water column draft at the appliance outlet. (Check equipment requirement. ) Changes in the adjustment of the 4" MG1 control should be made by adding or removing the washer-like weights (supplied with the control) to or from the weight holder chain assembly. After the control is adjusted, it's action will be entirely automatic, the gate will open or close by itself to correct for changes in the draft that occur in the chimney. ADJUSTMENTS PROVING SWITCH ADJUSTMENTS After proper airflow is established, the pressure switch adjustment is made by turning the pressure switch adjustment screw clockwise (See Figure 7) until burner operation stops. Turn the adjustment screw an additional 1/4 to 3/4 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! [. . . ] Connect 120 volts neutral power source wire and white wire from venter motor to terminal N on the CK-43F. Refer to the SWG Venter installation instructions for setting system airflow.

For furnaces or boilers, adjust the thermostat to call for heat and observe the power venting system for proper operation sequence. This should open the pressure switch contacts and stop burner operation. [. . . ]
