User manual FIELD CONTROLS 46285100

[. . . ] Attach the 1/4 inch tubing connector to the pressure tube on the SWG Venter. Connect the supplied 1/4" aluminum tubing to the tubing connector. Route the tubing to the CK-43F junction box and connect the tubing to the pressure switch. When routing the tubing, avoid kinking the tubing by bending the tubing too sharply. [. . . ] (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 counterclockwise until burner ignites. 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!THERMOSTAT HEAT ANTICIPATOR ADJUSTMENT After venting kit installation and checkout, check the amperage current draw through the thermostat circuit and adjust the thermostat anticipator accordingly. 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. 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. [. . . ] While system is operating, disconnect power to the venter motor. This should open the pressure switch contacts and stop burner operation. Venter does not activate when thermostat calls for heat. Check gas pressure switch for continuity across terminals when gas valve is pressurized. [. . . ]
