I purchased a used outdoor woodboiler this winter and just finished setting it up. It is not a brand name unit. I believe it was built by a start up in western MI that has since gone out of business. The issue I have is the draft damper solenoid. The first time I hooked up the unit the solenid made a very loud buzzing noise. A few minutes later it stopped when it burned out. After removing it I discovered it was a 12vdc unit with a 120vac suply line. I logged onto the grainger website and purchased a new 120vac pull solenoid. The unit arrived today and was installed tonight. When I applied power the unit had the same loud buzzing noise as the original unit. A few minutes later it burned out.
I am now a little confused and wondering if the damper design is flawed.
The first question I have is, when power is applied to a pull solenoid is it safe to keep the poser applied for a period of time. And it is normally a very loud buzzing noise?
This solenoid is designed to lift and hold the damper up until the water temp reaches the desired temp, then closes. How do other wood boilers do this.
Any help is greatly appreciated.
Thanks joe
