My wood boiler (Harman SF-160) heats the oil boiler in a series circuit. When my wood boiler reaches 150 degrees the electronic controls turn off the oil burner relay, preventing the oil burner from starting. This ensures that my wood boiler is the sole source of heat and hot water. I would like to install a motorized damper in the chimney flue coming from the oil burner to prevent heat from escaping. I was thinking about getting a normally open damper that will close when the oil burner is turned off.
Are there codes or other reasons why I shouldn't do this? Are there specific dampers made for this type of purpose? Right now I only see simple HVAC dampers that seem to be light duty only. I'm afraid one of those dampers might not be able to withstand the heat from the oil burner. If the damper were ever to get "stuck closed".... I would probably never know
