Hi,
Did you extend it with a Coleman roof-jack extension ?
Thanks,
Robert

no I didn't use a coleman roof jack...but just now I noticed the data chart on the furnace..so I'll measure from the top of the furnace to the top of the roof and check the chart and order the proper roof jack from your website to start with....any other suggestions for me Robert??

Hi,
See what that does first. You must have the correct roof-jack and any extensions for the furnace.
You'll need the hydroment sealant to seal around the flashing and swivel joints.
Thanks,
Robert
