PRECAUTIONS
!CAUTION
1.Do not short out terminals on gas valve or primary control to test. Short or incorrect wiring can cause equipment damage, property damage and/or personal injury.
2.This control is not intended for use in locations where it may come in direct contact with water. Suitable protection must be provided to shield the control from exposure to water (dripping, spraying, rain, etc.).
!WARNING
Before beginning any modification, be sure ALL electrical disconnects are in the OFF position. TAG THE DISCON- NECT SWITCHES WITH A SUITABLE WARNING LABEL. Electrical shock can cause personal injury or death.
INSTALLATION
1.Shut off power to the unit and install
2.Turn off main gas supply line valve.
3.Mark all wires going to the old valve with the terminal description that they are attached to.
4.If replacing an existing valve, disconnect all plumbing and electrical connections from the old control.
5.The control may be installed in any orientation except upside down (see figure 1). The arrow on the valve indi- cates the direction of gas flow through the control.
6.You should use new pipe that is properly chamfered, reamed, and free of burrs and chips. If you are using old pipe, be sure it is clean and free of rust, scale, burrs, chips, and old pipe joint compound.
7.Apply pipe joint compound (pipe dope) that is approved for all gases, only to the male threads of the pipe joints. DO NOT apply compound to the first two threads (see figure 2 for typical piping connections).
Upright, 90° from upright or vertical
8.Install gas valve by holding inlet boss with adjustable wrench. Do not tighten excessively, as this may damage the valve (Torque: 375
9.If the original gas valve has a barbed hose fitting, install pressure tube on barbed hose fitting of the replacement valve. Ensure that the pressure tube will not kink.
10.Do not remove barbed hose fitting from replacement valve even if the original valve does not have it.
11.Some applications will require modification of the pilot tube.
12.See SYSTEM WIRING when making electrical connections. Connect wires per Fig. 3 Diagram and Fig. 4 Chart.
13.After installation is complete, check the operation of the unit and, with main burners firing, check all joints for leaks using a soap and water solution. Retighten all joints where bubbles appear. DO NOT USE OPEN FLAME TO CHECK FOR LEAKS
