WARNING
SPECIAL ATTENTION FOR LIQUEFIED
PETROLEUM(L.P.)
PROPANE GAS-FIRED BOILER INSTALLATIONS
LPG appliances (boilers) shall be installed in
accordance with applicable provisions of NFPA 58
(Liquefied Petroleum Gas Code) latest edition for
installations in US and CAN/CGA B149.1 latest
edition for installations in Canada
Liquefied Petroleum (LP) propane gas is heavier than
air therefore Propane gas can accumulate at floor level.
If you suspect a leak, do not attempt to operate boiler.
A spark or flame from the appliance (boiler) or other
sources may ignite the accumulated propane gas
causing an explosion or fire. It is recommended that
inspections for gas leaks be performed periodically by
a licensed professional and that leak detection devices
be installed as a further safety measure.

BOILER ROOM AIR SUPPLY AND VENTILATION
An ample supply of air is required for combustion and
ventilation. When buildings are insulated, caulked and
weather-stripped, now or later on, direct openings to outside
may be required and should be provided. If the boiler is not
near an outside wall, air may be ducted to it from outside wall
openings.
Provisions for combustion and ventilation air must be made
in accordance with section 5.3, Air for Combustion and
Ventilation, of the National Fuel Gas Code, ANSI Z223.1-
latest edition, or CSA B 149.1 latest edition for natural gas
and propane or applicable provisions of the local building
codes. The following recommendation applies to buildings
of energy-saving construction, fully caulked and
weatherstripped.
INSTALLATION IN ENCLOSED BOILER ROOM REQUIRES
TWO UNOBSTRUCTED OPENINGS FOR PASSAGE OF AIR
INTO THE BOILER ROOM:
1. Air drawn horizontally from outdoors DIRECTLY
through an outside wall; one louvered opening near the
floor and one louvered opening near the ceiling, each
opening with a minimum FREE air passage area of 550
mm2per kW (1 square inch per 4000 BTUH) of total
appliances’ input.
2. Air drawn horizontally through HORIZONTAL DUCTS;
one opening near the floor and one opening near the
ceiling, each opening with a minimum FREE air passage
area of 1100 mm2per kW (1 square inch per 2000
BTUH) of total appliances’ input.
3. Air drawn VERTICALLY from outdoors; one opening at
the floor and one opening at the ceiling, each opening
with a minimum FREE air passage area of 550 mm2per
kW (1 square inch per 4000 BTUH) of total appliances’
input.
4. Air drawn from inside the building; one opening near
the floor and one opening near the ceiling, each opening
with a minimum FREE air passage area of 2200 mm2per
kW (1 square inch per 1000 BTUH) of total appliances’
input.
IF BOILERS ARE INSTALLED ADJACENT TO OTHER FUEL
BURNING EQUIPMENT, THE AREA OF FREE OPENINGS
MUST BE APPROPRIATELY INCREASED TO
ACCOMMODATE THE ADDITIONAL LOAD.
Openings must never be reduced or closed. If doors or
windows are used for air supply, they must be locked open.
Protect against closure of openings by snow and debris.
Inspect frequently.
No mechanical draft exhaust or supply fans are to be used in
or near the boiler area.
The flow of combustion and ventilating air to the boiler must
not be obstructed.
FLUE GAS VENTING REQUIREMENTS
The Victory II series boiler is a high efficiency, mechanically
induced draft boiler and, therefore, requires different venting
arrangements than natural draft, lower efficiency boilers.
THE FOLLOWING INSTRUCTIONS MUST BE CAREFULLY
READ AND FOLLOWED IN ORDER TO AVOID ANY HAZAR-
DOUS CONDITIONS DUE TO IMPROPER INSTALLATION
OF THE FLUE GAS VENTING SYSTEM.
The vent piping installation MUST be in accordance with
these instructions and with ANSI Z223.1-latest edition
NATIONAL FUEL GAS CODE, Part 7, Venting of Equipment,
or CSA B 149.1 latest edition for natural gas and propane.
Other local codes may also apply and must be followed.
Where there is a conflict between these requirements, the
more stringent case shall apply.
The use of a vent damper is NOT permitted on this boiler
series.
Approved Venting Applications
Victory II models VHS-90 through 180 are Category III
boilers and Model VHS-60 is a Category II boiler. These
boilers must be vented by proper 76mm (3") diameter vent-
ing system (see Category II and III venting—page 5).
Models VHS-90 through 180 are also Category Iboilers
when using a minimum of 127mm (5") diameter connector
and vented into a natural draft chimney or Type “B” vent
using a 76mm x 127mm (3"x5") diameter vent adapter, Part
# 660549 (see Category Iventing—page 10).
FOR CLEARANCES FROM
COMBUSTIBLES
CONSULT VENTING
MANUFACTURER
4VICTORY II VHS MODELS

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 AL29-4Csstainless steel
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:
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.

For a masonry vitreous tile-lined chimney which is not
exposed to the outdoors, use Table 1 in this Slant/Fin
manual for venting requirements. DO NOT install this
system into an unlined masonry chimney.
If a masonry chimney is exposed to the outdoors on one
or more sides below the roof line (exposed chimney), it
must be re-lined with a CSA listed metallic liner system.
See Table 2 in this Slant/Fin manual for venting
requirements of metallic re-lined chimneys.
If a Type “B” vent system is used, it must NOT be
exposed to the outdoors below the roof line. See Table 2
in this Slant/Fin manual for venting requirements. Vent
connectors serving appliances vented by natural draft
shall NOT be connected into any portion of mechanical
draft systems operating under positive pressure.
In some cases, the vent connector diameter must be up-
sized further to 6" or 7". Refer to Tables 1 and 2 for
installations requiring this increased size.
If this boiler is replacing a boiler which is connected to a
common venting system with other natural draft, gas-fired
appliances, the removal of the existing boiler from the
venting system is likely to cause the system to be too large
for proper venting of the appliances remaining connected
to it. At the time of removal of the existing boiler, the test
procedure specified in Appendix “B” must be followed.
