info on hovalyt 30

glennsmith

I have an hoval duolyt 30 -circa 1979-burns wood, oil, coal---The oil burner is working fine but its very expensive now and I wanted to try and use the solid fuel section. I dont know how to keep oil burner from not running. I set the switch in top to solid fuel but oil burner is still coming on. running oil portion and a fire causes the water to pound in the pipes. This must be dangerous. Also the vent in the rear is set at this middle position--is this right for both oil or solid fuel? I would like to know where to get a pdf manual or a hard copy manual and where parts might be ordered. the hoval. com website does not this burner in its online resources. I e-mailed their uk affiliate with these same requests-haven't heard back yet. Any direction/help would be appreciated. Glenn
