CATEGORY AND 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:

EZ Seal
Pro-Tech

International, Inc
Z-Flex, Inc. Z-Vent
Heat-Fab Part Numbers for various items of vent system are
listed in Slant/Fin Part List, Publication No. VHS-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 sealant specified by vent system manufacturer
for sealing of pipe and fittings. See Figure 4 for
proper application of vent pipe sealing for Safe-T vent
system by Heat-Fab. Inc.
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 VHS-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 for wall
thimble Part Numbers and more information.
CAUTION: Flue gasses exiting from the vent terminal will
condense. Building materials in the area of the vent terminal
should be protected from discoloration and degradation.
VENT TERMINATION LOCATION AND CLEARANCES
1. The venting system shall terminate at least 3 feet above any
forced air inlet located within 10 feet.
2. The venting system shall terminate at least 12 inches below, or
12 inches horizontally from, any door, window or gravity air inlet
into any building. The bottom of the vent terminal shall be at
least 12 inches above grade or the normal snow leve
whichever is greater.
3. Through the wall vents shall not terminate over public
walkways or over areas where condensate or vapor could
create a nuisance or hazard or could be detrimental to the
operation of regulators, relief valves or other equipment.
Minimum clerance of 4 feet horizontal distance is maintained,
from electric meters, gas meters, regulators and relief
equipment.
4. Vent termination must not be located in any confined space (i.e.
window wells, alcoves, narrow alleys) or under anyoverhang or
deck. Vent termination should not allow flue gas discharge
towards neighbor's windows or where personal injury or
property damages can occur.
B. Vertical Venting:
Figure 7 shows typical vertical venting. A fire stop is required
for each ceiling and floor penetration. 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 condensation
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 foot 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 manufac-
turer's instructions. The vertical portion vent pipe also must
be supported per manufacturer's instructions.
D. Minimum clearances of vent pipes from combustible con-
structions must be maintained (see Page 3).
E. Common venting with other appliances or another Victory II
boiler is NOT allowed.
F. The vent piping must terminate with a screened elbow or tee.
See Figures 5 and 6 for 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 condensation
drain requirements.
H. For roof passage of vent piping a U.L. listed roof flash-
ing must be used.
