Inquiry (采购产品): Gas/Oil Burner We have a 25 Mills H.B. Smith boiler with an oil burner built probably in the early 1970's. We would like to use a natural gas/oil combination burner if it is cost effective. Will you tell me if it can be done and give me some idea of the cost involved. Thank you for your time. **** Hidden Message ***** Mike Starks 65453 Company: Bipacco Coatings, LLC E-mail: mbipacco@centurytel.net **** Hidden Message ***** mbipacco@centurytel.net
