7) Assembly of Protech FasNSeal
a) FasNSeal General Notes:
• Do not cut 4" FasNSeal pipe. Consult FasNSeal instructions for method of cutting other 3" pipe.
• 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) Remove the hose clamp shipped on the CHG vent collar. Bend the three hose clamp tabs on this collar
outward slightly. Clean the exterior of the male end of the first piece of pipe and the inside of the vent
c ollar on the boiler. Remove dirt, grease, and moisture from the surfaces to be sealed. 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. Insert the male end of the pipe into the boiler vent collar until it bottoms out. Apply an
additional bead of silicone over the outside of the joint and the seams on the vent collar and smooth out
(Fig 6.10). Replace and tighten the clamp on the vent collar.
c) All other joints in the FasNSeal venting system rely on a gasket in the female end of the pipe for a proper seal.
d) Align the longitudinal seam of both pipes. 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.
e) Tighten the locking band with a nut driver.
f) Repeat (d) and (e) for the remaining FasNSeal components.
g) Allow the silicone to cure per the silicone manufacturer's instructions before operating the boiler.
8) Assembly of the air intake system:
a) Assemble the air intake system using either galvanized or PVC pipe.
b) If PVC piping is used, use PVC cement to assemble the PVC intake system components.
c) If galvanized piping is used, use at least two sheet metal screws per joint. Seal the outside of all joints.
d) 4" galvanized smoke pipe will fit inside the inlet collar on the CHG boiler. Depending upon the exact
OD of the pipe used, it may be necessary to crimp this pipe. Secure with a single #10 sheet metal screw
through the hole in the inlet collar and seal the outside of the joint with silicone. If PVC is used for the
intake system, use a short piece of 4" galvanized pipe to connect the PVC to the boiler. Silicone the outside
of the joint between the PVC and galvanized pipe.
e) Two 90-degree elbows may be used to make the 180-degree air intake termination elbow used on vertical
direct vent installations.
9) Rodent Screens - A rodent screen is provided with the CHG boiler for installation in the air inlet terminal.
