Heating will occur from the pointwhere the heater is installed to the top of thedrum. If the entire drum is to be heated, theSLDH should be installed as near to the bottomof the drum as possible. If only part ofthe material is to be heated, the drum heatershould be installed around the center or topsection of the drum. This will provide a fasterheat-up and save energy. However, care mustbe given to ensure that the material level inthe drum never falls below the location of theheater.Girth Extension Straps175
