Polyflue is a unique polypropylene flue gas venting system for Category II and IV gas fired heating appliances
No. The vent requires a minimum of one-inch clearance to all combustible material. For severe problems such as cold attics, contact the Technical Services Department of the manufacturer for alternative solutions.
No. It is not necessary to use screws with the AmeriVent's snap-lock connecting joints. Unlike other locking methods, the snap-lock joint is designed to come apart only when you want it to and not accidentally. Screws can cause problems with the joints and vent, and your inspector will probably red tag your system if you use them.
AmeriVent Flashings are made from .018 inch, 26 gauge, G90 galvanized steel, as are the firestops and the outer wall of the vent sections.
A Type B Gas Vent elbow is not designed to carry any load, therefore, whenever an elbow or offset is used, it must be resupported.
First, a metal firestop must be used at each floor level that the vent passes through, with the exception of the roof level where no firestop is required. Secondly, the firestop should always be located at the bottom surface of each floor level except for the upper floor where the firestop should be installed on top of the joist areas in the attic.
The rules may vary from area to area, and you should always check with the local building inspector. With the appliances used today, the use of an excessive number of elbows can cause condensation problems. Try to limit the installation to no more than two 90 offsets and to use offsets of no more than 45 wherever possible.
Yes. There is a correct direction, and each section is marked with an 'up' arrow that shows the proper orientation, or direction of the section, which is always away from the appliance.
No! Because the AmeriVent snap-lock locking system cannot be accidentally unlocked, unlike other types of cap locks, the Ameri-Cap will never blow off in strong winds.
