What is the major cause of vent-free appliance (heaters, logs, etc.) failure?
Almost all of the service problems found when inspecting vent-free appliances are from dirty pilots. This can usually be remedied by blowing directly on the O.D. S. pilot with a drinking straw to dislodge lint and dirt. A dirty pilot is not an indication of poor housekeeping. It will happen frequently in the cleanest of homes. Each year before appliance is lit, the owner should free-up pilot by blowing on it briskly. Never try to a clean pilot by inserting anything into the end of the pilot because that would cause damage to the pilot.
