ON/OFF Switch, HOT Surface Igniter | State Industries SRT80 120NE

LOW GAS PRESSURE SWITCH

OIM - OUTDOOR INTERFACE MODULE

The Low Gas Pressure Switch is a single pole, normally open pressure switch that will close its contacts when a rising pressure of 6.2 inches (1.53 kPa) w.c. is encountered. The contacts will open when the pressure falls below the fixed set point of 6.2 inches of w.c. The Low Gas Pressure Switch monitors the gas supply pressure to the heater. If the gas supply falls below the 6.2 inches of w.c., the main burner is extinguished (if heater is running) or the heater will not start up, see Figure 15.

The OIM is a device that monitors the control system. It monitors the ignition control assembly, the tank and outlet temperatures, the low water cutoff device, and the pressure switches. The display board provides operating information. It records and logs error messages for diagnostics. The module is equipped with a touch pad for easy access to observe menus and current status of control, see Figure 18.

ON/OFF SWITCH

The ON/OFF Switch is a single pole, single throw rocker switch. This switch provides 120V from the electrical source to the heater, see Figure 16.

WR IGNITION CONTROL BOARD

The WR Ignition Control Board performs the ignition sequence for the water heater. It controls the diagnostics of the system and monitors all the pressure switches, the flame sensing device, the thermostats, the E.C.O., and components that make up the control system. The difference between the WR Ignition Control Board is that the OIM board monitors all the controls and provides that information through the LCD display where the WR Ignition Control Board provides the means to control the complete sequence of operation and switches, see Figure 19.

HOT SURFACE IGNITER

The Hot Surface Igniter is a device that ignites the main burner by high temperature (1800°F). When the 120 VAC is applied to the igniter, sufficient heat is generated to ignite the main burner. Although improvements have been made to strengthen the igniter, it is still fragile and care must be taken when handling the igniter to prevent breakage, see Figure 17.
