Also turn off the main gas If replacing an existing valve, disconnect all plumbingand electrical connections from the old The control may be installed in any position exceptupside down (see figure 1).

3 The arrow on the bottomplate indicates the direction of gas flow through the You should use new pipe that is properly chamfered,reamed, and free of burrs and chips. If you are usingold pipe, be sure it is clean and free of rust, scale, burrs,chips, and old pipe joint Apply pipe joint compound (pipe dope) or teflon tape thatis approved for all gases, only to the male threads ofthe pipe joints. DO NOT apply compound or teflon tapeto the first two threads (see figure 2 for typical pipingconnections).6. If you are using a vise or open-end wrench to hold thevalve while installing piping, do not tighten excessively,as this may damage the See wiring pages 3-6 when making electrical con-nections. After all gas and electrical connections arecompleted, turn gas on and check for gas leaks withleak detection solution or soap suds. Bubbles formingindicate a leak.
