CATEGORY II AND III VENTING
1. Vent Material
A) The vent system for horizontal or vertical venting
(Category II and III) must be UL listed single wall 3"

diameter AL29-4C
stainless steel material. The follow-
ing manufacturers' systems are approved for use within
a specified minimum and maximum equivalent vent
length for each model. Proper adapter must be used as
a connector between Victory II boilers flue collar and
venting system as shown below:
Manufacturer
Heat-Fab, Inc.
ProTech System, Inc.
Flex-L International Inc.
Z-Flex Inc.
Heat-Fab Part Numbers for various items of vent system are
listed in Slant/Fin Part List, Publication No. VH-10PL.
B) When joining the various components of the above
listed vent systems, the manufacturers' instructions
should be closely followed to insure proper sealing.
C) Use GE-RTV 106 or Dow Corning 732 Sealant for
sealing of pipe and fittings. See Figure 4 for proper
application of vent pipe sealant.
D) All vent connections must be liquid and pressure
tight.
E) Flue vent system CANNOT be cut to length. Consult
manufacturer's instructions. For Heat-Fab system, use
slip joint connector (Part No. 7324-GC) to adjust pipe
lengths dimensions.
F) DO NOT use plastic or galvanized flue pipe.

2. Flue Length Restriction
Maximum and minimum equivalent flue length for different
systems are given in the tables on page 6. Equivalent flue
length is sum of straight flue lengths and equivalent
length of elbows. The vent termination is in addition to the
allowed equivalent lengths.
Example: Boiler Model VH-180 is to be installed at sea level
with 2 elbows using Heat-Fab vent system. Maximum
straight run would be: 40 - 2 x 3 = 34ft. If same boiler is to
be installed in Colorado Springs (5,980 ft. altitude), the maxi-
mum straight run would be: 20 - 2 x 3 = 14 ft.
3. Installation
A. Horizontal Venting:
Figures 5 and 6 show typical horizontal venting. For
combustible wall passage of vent piping a U.L. listed
thimble must be used. See Figures 5 and 6 f or wall
thimble Part Numbers and more information.
B. Vertical Venting:
Figure 7 shows typical vertical venting. A fire stop is
required for each ceiling and floor penetr ation. An
existing chimney (see Figure 8) may be used as a
chase for vertical venting. Other appliances CANNOT
be vented into the same chimney or vent pipe within
the chimney.
For both, horizontal and vertical venting, the following
points MUST be followed:
A. All Victory II boilers are equipped with a built-in con-
densation drain and trap. The trap loop must be filled
with water. DO NOT operate the boiler without filling
the trap with water to prevent flue gas discharge into
space. The drain should extend to a floor drain or to a
container which may require emptying periodically.
B. The horizontal vent pipe must be sloped upward from
the boiler at a pitch of at least 1/4" per 1 f oot of run, so
that the condensate from the vent system runs to the
drain trap.
C. The horizontal vent pipes must be supported with pipe
straps at intervals no greater than indicated by vent
pipe manufacturer's instructions. The vertical portion
vent pipe also must be supported per manufacturer's
instructions.
D. Minimum clearances of vent pipes from combustible
constructions must be maintained (see Page 3).
E. Common venting with other appliances or another Vic-
tory II boiler is NOT allowed.
F. The vent piping must terminate with a screened elbow
or tee. See Figures 5 and 6 f or horizontal and 7 and 8
for vertical termination information. A cap termination
may be used for vertical venting.
G. See Appendix A for vent system location and conden-
sation drain requirements.
H. For roof passage of vent piping a U.L. listed roof flash-
ing must be used.
