DuraVent FasNSeal Insulated 90 Degree Bird Screen Wall Mount Kit: a screened wall outlet for boilers and tankless water heaters

The DuraVent FasNSeal Insulated 90 Degree Bird Screen Wall Mount Kit is a kit for venting a wall hung boiler or tankless water heater through the wall behind it. Its outside outlet turns 90 degrees and has a screen to keep birds and debris out. DuraVent lists this kit as compatible with every Rheem gas appliance. FasNSeal is DuraVent’s stainless steel vent for high efficiency gas boilers, furnaces, and water heaters, built to carry pressurized exhaust and its acidic condensate outside. The vent has welded seams.

Along with the screened outlet, the kit includes an insulated wall thimble, the sleeve that carries the vent through the wall. An adjustable 90 degree elbow and a universal appliance adapter connect the route back to the heater. Choose a 3 inch or 4 inch kit on this page. The 3 inch kit needs an additional DuraVent appliance adapter, sold separately. An experienced professional handles the installation, and DuraVent calls for a qualified inspector to check the whole vent each year. Prefer a standard wall outlet? See the DuraVent FasNSeal Standard Wall Mount Insulated Kit. The DuraVent FasNSeal Insulated 90 Degree Bird Screen Wall Mount Kit ships free from My Cozy Outdoors with No Sales Tax (except WY) and the full manufacturer warranty.

FAQ

What is in the Insulated 90-degree Bird Screen Wall Mount Kit?

A 90-degree Bird Screen Termination, an insulated Wall Thimble, an adjustable 90-degree elbow and a Universal Appliance Adapter for venting a wall-mounted boiler or tankless water heater out through the wall behind it. The 3-inch kit adjusts vertically from 14-1/2 to 19 inches and horizontally from 9 to 13-1/2 inches; the 4-inch kit from 14 to 18-1/2 inches vertically.

Does it fit Rheem tankless heaters?

Yes, DuraVent lists it as compatible with all Rheem gas appliances. Note that the 3-inch kit requires the FSA-RI-4.2 adapter to connect to the appliance, so order that with it. For other brands, confirm the appliance manual lists a Category II, III or IV special gas vent such as FasNSeal and check its exhaust collar size.

What does the bird-screen termination do?

It ends the vent with a screened 90-degree outlet that keeps birds and debris out while directing the exhaust. Terminations still have to meet the appliance manual and NFPA 54 distances from windows, doors, air inlets, grade and the gas meter or regulator, so check those before cutting the wall opening for the thimble.

How are the joints made, and is sealant needed?

No sealant or screws: every FasNSeal female end carries a triple-lipped gasket and a built-in locking band. Push the male end in and turn until half the bead is covered, then tighten the band snug plus a quarter turn. Pitch the horizontal run at least 1/4 inch per foot back toward the appliance, which the thimble’s adjustable length allows.

What clearance and drain rules apply?

Clearance comes from the FasNSeal manual’s table by rated temperature, for example 4 inches around an unenclosed horizontal run and 1 inch vertical at 300 F for 3 to 4 inch single-wall vent, with the insulated thimble handling the wall. If the appliance lacks an internal drain, add a Universal Condensate Drain near the flue collar from the FasNSeal category.
