Coleman/Revolv 91 in -102 in Roof Jack (FC-7121)

THIS IS NOT TO BE USED WITH NEW RG/MG1E MODEL REVOLV'S. THOSE REQUIRE A MILLER PRODUCT SINCE THEY ARE NOW MADE BY NORTEK. This telescopic roof jack assembly is designed for Coleman fuel furnaces, with a 5" diameter outlet and an adjustable flange for flat or pitched roof installation. Note:  When purchasing a new furnace, Coleman requires that you purchase a new roof jack assembly and roof jack sealant to prevent carbon monoxide emissions. When selecting the height of the roof jack, the DGAA Series measures from the floor to the roof, while the DGAH Series measures from the floor to the roof and adds 20 inches.
