JOINT CONNECTIONS
the female end of each FasNSeal W2
component incorporates a sealing gasket. the
mechanical locking band is built into the outer
tube of FasNSeal W2 male end. examine all
components prior to installation. Gaskets must
be in proper position or flue gases could leak
and result in carbon monoxide poisoning.
1. Insert the male end into the female section.
Push the units together and turn them until
the bead of the male end is seated against
the flared end of the female section (see
photo to the right). From within the tube,
the sealing gasket must not be visible. this
creates the needed airtight seal for Category
II, III or IV appliances. align the seams on the
vent lengths and orient them upward in all
horizontal applications.
2. tighten the locking band with a nut driver
until snug plus 1/4 turn.
Before proceeding, recheck all joints and
ensure that all male sections extend to the
top of the flared female end and all clamps
are tightened.
Stop bead on male end must be pushed
directly against the flared end of the female
end. When checking the inside of the joint, the
gasket is fully covered and out of sight.
APPLIANCE CONNECTION
Connect FasNSeal W2 to the appliance
flue collar as directed in the appliance
manufacturer’s instructions. If the appliance
flue collar is not designed to accept FasNSeal
W2 directly, an adapter may be available.
Some appliance adapters may require a
Single-wall to Double-wall transition adapter.
