Mount the gas control 0-90 degrees, in any direction, from the upright position of the gas control knob, including vertically. This may burn out the heat anticipator in the thermostat or damage the DI module.IMPORTANT: Allow 60 seconds after shutdown before reenergizing the step-opening model to assure light off at step pressure. . the manual gas control knob is in the ON position. If a gas leak is detected, tighten the pipe connection. The pilot must be manually relit when normal burner operation is desired. thatguy, I hear you. Loss of power closes the automatic valves, but leaves the pilot lit, ready to return to normal service when power is restored. 0000017061 00000 n
The gas control knob must be held depressed or the thermocouple must be heated sufficiently to hold the safety control valve open.ON: Permits main burner and pilot gas flow. I have a Superior Gas Fireplace model DR-500CMP that currently has a Honeywell Millivolt Gas Valve that I need to replace but the part number does not cross to a valid number. . The gas control is likely to have operated for more than 200,000 cycles. Making statements based on opinion; back them up with references or personal experience. Test the voltage using an AC voltmeter. On LP gas installation, use compound resistant to LP gas. And we already know that the t'stat + terminal is jumpered to the t'couple + terminal, and that the t'stat - terminal is jumpered to the limit switch + terminal.

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. If tubing is used, ensure the ends are square, deburred and clean. If the O-ring is not attached or is missing, do not use the flange. Water heater not working? Attempt to light pilot burner flame following procedures in the Light the Pilot Burner Flame section. Is there a solution to add special characters from software and how to do it. Combination screw and quick-connect terminals on TRADELINE models. a. It must be replaced in case of any physical damage such as bent terminals, missing or broken parts, stripped threads, or evidence of exposure to heat. Repeat after allowing the main burner to cool. Your system is quite old and somewhat unsafe, in that the pilot comes off ahead of the safety valve. Some considerations are: Cycling frequency. Thanks. Voltage drop across the switch terminals Burner on: 35 mv or less. Use only glass approved by Vermont Castings, Majestic Products on this fireplace.

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. A separate reset button must be held down to permit gas flow while lighting the pilot; can be pushed down only in the PILOT position. Check the pilot burner flame adjustment. Force or attempted repair may result in fire or explosion. Yes, there is one screw to adjust the gas to the pilot and another to adjust the gas to the main burner. A consequence of unexpected shutdown. Both pilot and main burner are shut off. Turn off the gas supply valve to your appliance to test whether your valve is capable of shutting down properly. The low-pressureregulator maintains outlet pressure at the preset step rate for several seconds. Regulator adjustment is accessible from top of gas control.MOUNTING: Can be mounted 0 to 90 degrees in any direction from the upright position of the gas control knob, including vertically.TEMPERATURE RATING:VR8200A,C,H,J; VR4200A,C,H: 0 F to +175 F [-18 C to +79 C].VR8200M,P; VR4200M,P: -40 F to +175 F [-40 C to +79 C].

See Fig. All adjustments, wiring connections, and pilot outlets are accessible from the top of the gas control. You should NOT short out the t'stat terminals to check it. If the desired outlet gas pressure or gas flow rate cannot be achieved by adjusting the gas control, check the gas control inlet pressure using a manometer at the inlet pressure tap. IMPORTANT: The specifications given in this publication do not include normal manufacturing tolerances. I would verify the valve type - It would either be the SIT 820 or the Honeywell VS8420. Refer to Figs. Inlet and outlet pressure taps included; both taps accessible from the top of gas control. Fig. The pilot works fine but the main burner does not come on by the wall mounted thermostat or the manual on/off switch. Before lighting, smell all around the appliance area for gas. If the inlet pressure is in the normal range (refer to Table 7 or 8), replace the existing gas control. Fig. Take care when handling the refractory panels as they are fragile until held in place and supported. This is a very useful thread and am learning a lot from it partly because of my situation with my current Weil McClain boiler. 0000006973 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.
