Operating instructions

D.
Applyhigh temperature siliconein an even ¼"bead ap-
proximately 1/4"from the end of the vent hood's connecting
vent pipe. Also,run a similar sizebead of siliconesealant
down the seam weld of the vent pipe. Thenpush the female
end over the vent hood's connecting vent pipe. Now fillin
the channel inlet with silicone sealant. Do not try to insert
the joiner band, instead fastenthe vent pipe to the vent
hood's pipe with a steelgear clamp.
1. Apply the high temperature silicone around the male
end of the pipe in an even ¼" bead. Siliconebead
shouldbe approximately ¼" fromthe end of the male
end. Also,run a similarsizebead of siliconesealant
down the seam weld at the end of each joint.
2. Theseams on the vent pipe should be aligned and ori-
ented upward in allhorizontal vent pipe runs.
3. Insert the male end of one into the female end of the
other. Push the pipe together sothe female end rests up
against the stop bead of the male end.
.
Insert a StaR-Joiner Band into the inlet of the beaded
channel. Feed the Joiner Band in so it makes its way
around the pipe, back to the channel inlet and it over-
laps itself by about 1/2".
.
Cut the excessJoiner Band soit lays fiatin the beaded
channel.Fillthe inlet of the beaded channel with high
temperature silicone.Smooth out the siliconeover the
channel inlet and the siliconebetween the female end
and the stop bead of the male end.
.
Horizontal venting shall have a slope not less than ¼"
(6.4mm) every 12inches (305mm) downward away
from the boiler to prevent collection of condensate
throughout the assembly.
7. Allowthe sealant to cure for 24hours before operating
the appliance.
For ProTech Systems FasNSealstainlesssteel vent pipe
no cleaningfluid isrequired. For 3" vent pipe runs on 2,
3,4 and 5 section boilers, begin by locating the FasNSeal
AmetekAdapter over the boiler's induced draft blower.
Continue the vent pipe run with 3" FasNSealvent pipe.
For 6 and 7 section boilers, begin by locatingthe FasNSeal
AmetekAdapter over the boiler'sinduced draft blower.
Thenconnect a FasNSeal3" to 4" increaserto the 3"
adapter outlet. Continue the vent pipe run with 4" FasNSeal
vent pipe. Other than the Ametek Adapter and increaser
fitting,DO NOT use 3"vent pipe on 6 or 7 section boilers.
FasNSealvent pipe isjoined and sealedby the use of an
internal sealing gasket and alocking band on the female
end of each vent pipe. Allcomponents should be examined
for possibleshipping damage prior to installation. Align
allvent pipe seamsand orient upward in allhorizontal
applications.Adjustablevent lengths are availablefor 4"
diameter vent piping. For 3" diameter vent piping, square
cut male end at the desired length. For2, 3, 4 and 5 section
boilers usingthe VH-1-3" vent hood, connect the FasNSeal
Vent to the VH-1-3"vent hood using FasNSealAdapter
#FSC-DUN-3.Thisadapter has no internal sealinggasket.
Toattach the adapter to the vent hood, crimp the 3" vent
hood pipe,apply a 1/4"bead of high temperature silicone
sealantaround the outside of the vent hood's crimped
connecting pipe and a similar bead of high temperature
siliconearound the inside of the FasNSealadapter. After
pressing the two pipes together and tightening the locking
band, finish creating a complete sealby fillingthe FasNSeal
adapter'snotched holewith high temperature silicone.
For 6 and 7 section boilers using the VH-1- 4"vent hood,
an adapter isnot required. The4" FasNSealvent pipe con-
nects directlyto the VH-1-4" vent hood, and isjoined and
sealedby the internal gasketand lockingband.
Tojoin and seal the FasNSealvent pipe:
1. Insert maleend into female section.
2. Push the units together as far as possible.
3. Firmly tighten locking band with a nut driver.
4. DO NOT penetrate the FasNSealvent pipe with fasten-
ers.
.
Horizontal venting shallhave a slopeof not less than
¼"(6.4mm) every 12inches (305mm) downward away
from the boiler to prevent the collectionof condensate
throughout the assembly.
o
Support Spacing:
Do not restrict thermal expansion movement of the vent. The
vent pipe must expand and contract freely with temperature
change.Eachrun of vent piping shallbe supported as follows:
A. Z-Flex stainlesssteel vent piping requires a loosefitting
metal strap or similar support at eachjoint at amaximum
of 4 feetbetween supports.
B. Heat-Fab stainless steelvent piping requires a support for
every6 feet of horizontal piping run. The support must be
securedusing at least #10fasteners to a solid material (solid
masonry or wood framing or blocking.)Do not fastento
drywall sheathing using hollowwall anchors. Each sup-
port willbe 11/2inch lower than the previous support when
spaced 6feet apart.
C. Flex-Lstainlesssteelvent piping requires a loose fitting
metal strap or similar support at eachjoint at amaximum
of 4 feetbetween supports.
D. ProTech stainlesssteel vent piping requires one loose fit-
ting FasNSealsupport strap for every6' of horizontal vent.
