7) Assembly of Protech FasNSeal:
a) FasNSeal General Notes:
• Do not cut 4” FasNSeal pipe. The male end of 3” FasNSeal may be cut. Cut must be square to ensure a proper seal.
• Orient FasNSeal vent components so that the arrows on the piping labels are in the direction of flue gas flow.
• Support horizontal piping sections at intervals of 6 feet or less.
• Vertical venting systems must be supported by at least one FasNSeal support. An additional vertical support is
required after any offset.
b) Start assembly of the vent system at the boiler. Remove the hose clamp shipped on the BWF vent collar. Bend the three
hose clamp tabs on this collar outward slightly.
c) Clean the exterior of the male end of the first piece of pipe and the inside of the vent collar on the boiler. Remove dirt,
grease, and moisture from the surfaces to be sealed. Dry surfaces or allow to dry thoroughly.
d) On the male end of the pipe, apply a ¼” wide bead of high temperature silicone approximately 1/4 inch from the male end
of the pipe.
e) Insert the male end of the pipe into the boiler vent collar until it bottoms out.
f) Apply an additional bead of silicone over the outside of the joint and the seams on the vent collar and smooth out (Fig 23).
g) Replace and tighten the clamp on the vent collar.
h) All other joints in the FasNSeal venting system rely on a gasket in the female end of the pipe for a proper seal.
CAUTION
• MAKE SURE THAT GASKET IS IN POSITION AND UNDAMAGED IN THE FEMALE END OF THE PIPE.
• MAKE SURE THAT BOTH THE MALE AND FEMALE PIPES ARE FREE OF DAMAGE PRIOR TO ASSEMBLY.
• IF 3” PIPE IS CUT, CUT END MUST BE SQUARE AND CAREFULLY DEBURRED PRIOR TO ASSEMBLY.
i) Align the longitudinal seams of the pipe. Insert the male end of the second pipe into the female end of the first pipe until
the bead on the male end contacts the flare on the female end (Fig. 24).
j) Tighten the locking band with a nut driver.
k) Repeat Steps (i) and (j) for the remaining FasNSeal components. If a termination elbow or tee is used, use this procedure
to complete the exhaust system.
l) To join FasNSeal to a 3” VH-1 terminal, use a Protech FSA-M-3 “Modine Appliance Adapter” (Protech #300444). Apply
a ¼” bead of silicone to the terminal connection about ¼” from its end. Slip the female end of the adapter over the
terminal end so that there is an overlap of at least 1 ¾ inches. Tighten the hose clamp to mechanically lock the pipe onto
the terminal. Apply and smooth silicone over the outside of the joint including the hose clamp in the FasNSeal pipe.
Connect the female end of the venting system to the male end of the adapter per Steps (i) and (j) above.
