    It could be any number of different things. Go to the top of this page to "Before You Ask" click on the second "here" in the sentence. Then look for my ugly mug Tim McElwain and you will see under my picture procedures for checking Powerpile, which is what you have for a system. The VS8187 is by the way obsolete and no longer available unless maybe on E-bay.

    Things to consider:

    1. Clean the pilot while you have it out change the pilot generator it is a Honeywell Q313
    2. Check for loose connections (watch out for poor connections in wire nuts)
    3. If you have to replace the gas valve use a VS820A valve, it will require some changing around of the pilot tubing. This valve will replace everything on the manifold.
