How to Troubleshoot a Honeywell SV9500M-2682
A malfunctioning gas valve will have a serious effect on your automated home heating system, perhaps meaning you will receive water which is too hot, too cold or provided at the wrong time. In order to troubleshoot problems which could occur, analyze issues with the temperature dials, the pilot light and the pressure regulator dial. Does this Spark an idea?

Fix the problem of water temperatures which are far too low or far too high by adjusting the dial located on the front of the gas valve. Choose the appropriate setting from the "Low," "Pilot," "Warm," "Hot" and "Very Hot" options on the dial.

2
Adjust the pilot light if the gas valve is not igniting. It is reasonably easy to make the pilot light more potent. The gas valve has a pilot light adjustment screw located on top of the gas valve and this can be adjusted using a flathead screwdriver. The pilot light adjustment will raise or lower the height of the light inside.

Reduce the pilot light potency -- using the same method outlined in Step 2 -- if the gas valve is seemingly inexplicably cutting out. If the pilot light is too large then it may trigger breakers within the valve, shutting down the system.

4
Adjust the pressure regulator if necessary. The gas valve must match the pressure rating of the water heater and this can be attained by removing the cap screw on the top of the Honeywell gas valve, exposing the pressure regulator screw. Turn it clockwise to raise the pressure or counterclockwise to lower it.
