CHANGING TO HIGH EFFICIENCY?
UTILIZE YOUR EXISTING VENT!
FasNSeal® 80/90 is a unique, patent pending, system that exhausts 90+ AFUE
condensing appliances with Type B atmospheric units, utilizing the existing vent.
Using your preexisting common vent, our cap improves the operation of both the remaining atmospheric appliance, and the
new condensing unit, while not disturbing nished space during installation.
Finally a solution when you need to deal with narrow lot lines, clearance to window and door openings, or when side wall
venting just isn’t practical.
