Our Answer:

It does indeed sound like you are encountering an issue with back draft that is causing the pilot to extinguish or a possible fluctuation in gas pressure that causes the pilot to go out on shutdown or start up. If the pilot goes out randomly, it is more likely a draft issue and a high wind cap such as this model could solve the issue. It will be necessary to verify the brand of piping that is used to guarantee proper fit. If the pilot goes out preceding or following a heat cycle, a gas pressure deficit may be the problem. Pressure that is diverted to the main burner can cause enough of a fluctuation for the pilot to go out, if the pressure is far enough out of spec.

In Response to Question:

I am having problems with my old Seigler furnace. The pilot will randomly go out after two or three heat cycles. I have adjusted and replaced many of the components, and am starting to think i may have the wrong vent cap on. I have taken measurments and all building code distances are right. I live in a very cold climate, high in the rockies, with high wind at times. Can you recommend the type of vent cap i should be using?
