ELECTRICAL GAS VALVES .The electrical gas valves are designed to shut off the flow of either natural or LP gas to the appliances upon actuation of the regulat- ed release assembly. The valves are available in sizes of 3/4 in., 1 in., 1 1/2 in., 2 in., and 3 in. The valve is held open by an ener- gized solenoid and upon system actuation, the switch contacts in the regulated release assembly open, thus de-energizing the cir- cuit to the gas valve solenoid, causing the valve to close. Valves are available in 120 VAC and are UL Listed. Part No. .. 13707 13708 13709 13710 17643 Description 3/4 in. Solenoid Gas Valve (ASCO) 1 in. Solenoid Gas Valve (ASCO) 1 1/2 in.

FIGURE 26 004210 MANUAL RESET RELAY The manual reset relay, Part No. 14702 or Part No. 426151, is required when using an electrical gas valve shut-off system. After the electric gas valve has closed, either due to system actuation or power failure, the valve cannot be re-opened, allowing gas to flow, until the reset relay button is manually pressed, re-energizing the circuit. The reset relay is available 120 VAC. The manual reset relay is also recommended for electrical shut down.

Switches are available in kits: One Switch Kit, Part No. 423878, Two Switch Kit, Part No. 423879, Three Switch Kit, Part No. .. 423880, and Four Switch Kit, Part No. 423881. Mounting hard- ware and 12 in. (305 mm) long wire leads are provided with each kit. Each switch has a set of single-pole, double-throw contacts rated at: UUcUUCSA Rating 250 VAC, 21A Resistive 250 VAC, 2 HP ..125 VAC, 1 HP ENEC Rating IE4T105~ Approved 250V, 21A Resistive 8A Motor Load /N.O.

This switch must be used to close a supervised circuit to the building main fire alarm panel when the ANSUL AUTOMAN release actuates. This action will signal the fire alarm panel that there was a system actuation in the kitchen area. The switch kit contains all necessary mounting components along with a mounting instruction sheet. The switch is rated 50 mA, 28 VDC. .. TOWARD ANSUL AUTOMAN " WHEN SPACER AND SWITCH ARE PROPERLY MOUNTED, THIS DIVIDER MUST BE BETWEEN THE / N.O. AND N.C. TERMINALS /COM /N.O. ......,,- .......
