weight of the material employed, to maintain clearances, prevent physical damage and separation of joints. A
vent pipe increaser or reducer may be required for connecting the venter to the vent system. Smaller vent pipe
sizes than a chimney-vented system may be used for the vent system.
Route the vent pipe from the appliance to the venter using as few elbows as possible. The horizontal section
of the vent pipe should have a slight upward slope from the appliance to the venter. For clearances to

check unit very carefully for damage. Rotate venter wheel to ensure that the motor and venter wheel rotate
freely.DONOTinstallifanydamageisapparent.Refertounitsizingcharttocheckproperventersizing.
