104060000 Nordyne CMF roof jack 12 inches
SRJ1 roof jack fits most all Nordyne CMF furnaces with 4" vent pipes. Must be installed on a flat surface. To install on a pitched roof, order the correct sloped roof adapter that corresponds with the pitch of your roof.
The distance from the flange to the bottom of the roof jack is 12". The bottom of the roof jack must be lower than the ceiling.
For a replacement crown, order part # 104360000.
The outer double-wall of the roof jack is 8" in diameter. The bottom end of the roof jack must hang below the ceiling and connect to vent pipe (available separately) which extends up from the furnace. Adjustment is made by sliding the 4" vent pipe (not included) up and down inside the roof jack. Size of roof jack is determined by measuring the distance from the ceiling to where the flange sets on the roof.
Shipping package size is 15x15x29". Picture shows what the roof jack looks like but not the actual length.
