Can folks tell me why gas furnaces may be equipped with automatic flue dampers, but it appears that oil furnaces almost never are. It appears that Honeywell etc., don't even make a damper approved for oil. Either I'm mistaken, or there has to be a reason!

A couple of companies used to make them but not now. I've worked on several over the years & they worked well on tall, high draft chimneys. The reason for their discontinuance was probably lack of sales. You can't even get repair parts anymore.

The last one I saw (about 15 years ago) was popular with one local company. They must have installed hundreds of them. That particular brand had a problem with the end switch. The damper would fail and the switch had already come loose and did not sense the dampers failure to open. That particular one was in an old church and the soot was everywhere. I would make sure if/when you locate one, it isn't a piece of junk.
