BUGS MEAN TROUBLE
If your furnace has been turned off for a few weeks or during the summer, you may have some trouble getting it started again. Part of the main burner at the bottom of you're furnace (see J) is a favorite hiding place for the common spider. It likes to spin a web and lay eggs there and sometimes this blocks the flow of gas through the orifice and main burner. Use a soft brush (clean paint brush) and clean around the orifice. This may clear up any trouble. If not, refer to Service Checks, or call a qualified serviceman.
DON'T unscrew the orifice or try to clear it by pushing anything through the tiny hole. Call your qualified serviceman.
