CATEGORY II AND III VENTING (Pressure Venting)
1. Vent Material
A) The vent system for horizontal or vertical pressure
venting (Category II and III) must be CUL listed
single wall 3" diameter AL29-4C
material. The following 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 Type/System
Heat-Fab.
Saf-T Vent
Inc.
Heat-Fab. Saf-T Vent
Inc. EZ Seal
ProTech
FasNSeal
System, Inc.
Flex-L
International, StaR-34
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-1OPL.
For clearance from combustibles consult venting
manufacturer.
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-Tvent
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 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: 12.2 - [0.6 x 3] = 10.4 m (40 - [2 x 3] = 34ft.)

3. Installation

A. Horizontal Pressure Venting:
Figures 5 and 6 show typical horizontal pressure
venting. For combustible wall passage of vent piping
an approved Slant/Fin wall thimble, Part No. 442321
must be used. See Figures 5 and 6 for wall thimble
Part Numbers and more information.
B. Vertical Pressure Venting:
Figure 7 shows typical vertical pressure 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 pressure 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 20 mm/m (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 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
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 CUL listed roof
flashing must be used.
