• Unpack the Double Shutoff Valve (R947-3010/R947-3020). For each connection flange, loosen 2 screws on one edge, and remove the 2 screws on the other edge, then slide the flange off the valve body block (screws are M6/M8 socket head). • Remove the two white protective plastic covers from the valve body. • Make sure the O-rings and the grooves are clean and in good condition. • Install the Double Shutoff Valve with the gas flow matching the direction indicated by the arrows on the casting. • CAUTION: If the flow is not in the same direction of the arrows, the valves may not operate properly. • Mount the Double Shutoff Valve only with the solenoid vertical upright to horizontal.
• CAUTION : The valves must be de-energized and their gas supply shut off before installing the Position Indicators.
• Insert the Visual Indicator and its attached O-ring using a 5⁄8 " (16 mm) open end wrench. • Turn clockwise until the Visual Indicator is sufficiently tightened. • DO NOT overtighten or you will destroy the rubber O-ring. • Apply the adhesive-backed stickers supplied which show what the colors of the indicator signify to the Double Shut- off Valve. The stickers should be applied on each side of the valve body so the operator can refer to either of them while viewing the Visual Indicator. • After installation is completed perform a leak test to verify that no leak- age occurs. • For installation of a Closed Position Indication Switch R950-5260 follow the instructions supplied with the R950-5260. If a Closed Position Indica- tion Switch is used, it must be installed on the upstream valve. Installation • Remove the two plugs and O-rings in the bottom of the valve with a 3⁄16 " (5 mm) hex key wrench. These are the taps were the Indicators go.
• Clean the mounting surface of the flanges. Make sure they are in good condition. • Attach the Double Shutoff Valve to the flanges using the M6/M8 socket cap screws supplied.
WIRING
• Disconnect all power to the valves before beginning the wiring to prevent electrical shock and equipment damage. • Do not exceed the electrical ratings given in the specifications and on the Double Shutoff Valve. • Attach a flexible ½ ” NPT conduit to the DIN connector. • Route the wires through the conduit and the DIN connector. • Use 14 or 16 gauge wire suitable for at least 167°F (75°C). • Connect the wiring to the appropriate screw terminals in the DIN con- nector. • Plug the DIN connector onto the AMP terminals. Fasten the DIN connector with the screw supplied. • CAUTION: All wiring must comply with local electrical codes, ordinances, and regulations. An ultimate electrical enclosure must be provided.
• Use a 5 mm/6 mm Allen wrench for the mounting screws.
• Tighten the screws in crisscross pattern.
• Do not overtighten the screws. Follow the maximum torque values listed below. screw size M6 M8 max. torque (lb-in.) 62 134 • After installation is completed perform a leak test to verify that no leak- age occurs.
POSITION INDICATION
Valve position indication is required by various authorities having jurisdiction. Two indicators, one of which might be the Closed Position Indicating Switch, are shipped with, but not attached to, the Double Shutoff Valve to insure that the indicators are not damaged during shipment. Therefore install the indicators onto the Double Shutoff Valve after mounting the Double Shutoff Valve onto the gas train and before the valves are put into service.
WARNING: Situations dangerous to personnel and property may exist with the operation and maintenance of any combustion equipment. The presence of fuels, oxidants, hot and cold combustion products, hot surfaces, electrical power in control and ignition circuits, etc., are inherent with any combustion application. Components in combustion systems may exceed 160°F (71°C) surface temperatures and present hot surface contact hazard. Fives North American Combustion, Inc. suggests the use of combustion systems that are in compliance with all Safety Codes, Standards, Regulations and Directives; and care in operation.
