Millivolt Gas Valves - Resideo 0000010110 00000 n Regular preventive maintenance is important in applications that place a heavy load on system control such as in the commercial looking and agricultural and industrial industries because: The VR8200, VR4200 gas controls provide 3-position (OFF-PILOT-ON) manual control of gas flow. Remove the thermopile wiring connector from the gas control. I suspect they are the "white" terminal and TH1. Zero clearance sleeve is only required for combustible walls. Do NOT use Teflon tape. Turn the gas control knob to the "On" position if the main burner does not turn on when the thermostat or controller is adjusted to start the appliance. Allow the appliance to run through one complete cycle to ensure that the controls are functioning in the correct manner. If it then "clicks" meaning it is opening with voltage supplied to it than most likely it's not the gas valve which is bad. The reduced pressure on the bottom of the automatic valve diaphragm repositions the diaphragm downward away from the valve seat, allowing main burner gas flow. 0000137823 00000 n If it goes out, repeat steps 36. The diaphragm-operated second automatic valve opens under the control of the regulator and closes if gas or power supply is interrupted. Refer to Table 7 or 8 for factory-set nominaloutlet pressures and adjustment ranges. Unscrew compression fitting from the pilot outlet (Fig. The low-pressureregulator maintains outlet pressure at the preset step rate for several seconds. If above 11 ohms, replace the gas control.

I was just wondering about this the other day. Place gas control knob in PILOT position. IF CHECKING GAS INPUT BY CLOCKING THE GAS METER: IF CHECKING GAS INPUT WITH A MANOMETER (PRESSURE GAUGE): The gas control outlet pressure should match the manifold pressure listed on the appliance nameplate. How do I test Millivolt valve system when Pilot is on If it is re-energized within 60 seconds, it may bypass or shorten the length of the low-pressure step. With the loss of outlet pressure, the second automatic valve closes and is held closed by spring pressure on the diaphragm. If outlet pressure begins to rise, the pressure regulator the diaphragm moves slightly higher, allowing less gas flow to the gas control outlet. 0000057714 00000 n If you have not I will give some ideas.
