flue vent 94

[Jim Green]

Has anyone changed the furnace vent from a 78% to a 94% and installed a new vent tube. I dont think you can use your old metal double wall vent pipe

Gotta be plastic (follow the manufacturers installation instructions)

Jim,

I pulled this Installation Manual up in about 2 minutes.

You might be in a little over your head.

If your have a questionable install the equipment efficiency would drop through the floor .

Improper Installation would affect your Family's Safety.

Please contact a Professional Heating & Air Installer. ;)
