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.

VENTING SYSTEM REGULAR INSPECTION
A. Inspect the system regularly for condensation, corrosion
and/or physical damage. A qualified professional should
service the boiler annually and include such an inspection at
that time. The homeowner should look over the system
monthly for damage, water stains, any signs of rust, other
corrosion or separation of the flue (vent) tubing and fittings.
B. Should an inspection turn up signs of condensation, corrosion
or damage, the boiler should be shut down immediately and
the condition should be corrected by a qualified professional.
C. 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. Periodic inspection should be
made of this assembly for deterioration of the tubing and to
insure that the trap is not plugged. If it is plugged or appears to
have excessive sediment in it, it should be removed from the
drain assembly, straightened out to clear the obstruction,
reformed, filled with water and reinstalled as before.
GAS PIPING
A. Local installation codes apply. The pipe joint compound used
on threads must be resistant to the action of liquefied
petroleum gases.
B. The gas supply line to the boiler should be run directly from
the meter for natural gas or from the fuel tank for L.P. propane
gas. See page 2 for location of union and manual main shut-
off valve that may be specified locally.
Selecting pipe size for natural gas:
1. Measure or estimate the length of piping from the meter to
the installation site.
2. Consult gas supplier for heating value of gas (W/m)
(BTU/cu. ft.).
3. Divide boiler rated input by heating value to find gas flow
in piping (m3/hr.) (cu. ft. per hour).
4. Use table below to select proper pipe size.
Example: Boiler model VHS 150 is to be installed. Distance from
gas meter to the boilers is 9.1 m (30 ft). Heating value of natural
gas is 10 557 W/m3(1020 BTU/cu. ft.) Select proper pipe size.
At 9.1 m (30 ft.) length of pipe, match required capacity from
table on this page (choose higher capacity, in this case 4.3 m3/hr.
(152 cu. ft. per hour).) Required pipe size is 19 mm (3/4").
Improper gas pipe sizing will result in pilot flame outages,
insufficient heat and other installation difficulties. For more
information and also if other appliances are to be attached to the
piping system, see Appendix C of National Fuel Gas Code ANSI
Z223.1-latest edition or CSA B 149.1 latest edition for natural
gas and propane.
C. The boiler and its gas connection must be leak tested before
placing the boiler in operation. Use liquid soap solution for all
gas leak testing. DO NOT use open flame. This boiler and its
individual shutoff valve must be disconnected from the gas
supply piping system during any pressure testing of that
system at test pressures in excess of 3.5 kPa (1/2 PSIG). This
boiler must be isolated from the gas supply piping system by
closing its individual manual shutoff valve during any
pressure testing of the gas supply piping system at test
pressures equal to or less than 3.5 kPa (1/2 PSIG).
D. All gas piping used should be inspected thoroughly for
cleanliness before makeup. A sediment trap must be
provided, as illustrated on page 2.
E. The minimum and maximum gas supply pressure (at the inlet
of gas valve) are shown on the boiler rating plate for the type
of gas used. Gas supply pressure should never be less than
minimum or more than maximum pressure when the boiler
or any other appliance is turned on or off.
ELECTRICAL WIRING
DANGER:Before wiring, always turn off electric power
supply, otherwise, shock or death can result.
1. Power Supply
A separately fused circuit is recommended. Use a standard
15 Amp. fuse or breaker and 14 gauge conductors in BX
cable or conduit.
Provide disconnect means and overload protection as
required. See boiler wiring diagram (Figure 11a) and ladder
diagram (Figure 11b).
Boiler must be electrically grounded in accordance with the
requirements of the authority having jurisdiction, or, in the
absence of such requirements, with the Canadian Electrical
Code, CSA-C22-1, Part 1-latest edition.
2. Power Connection
A. Remove electrical junction box cover.
B. Hot connection lead is black. Neutral connection lead is red.
C. Connect ground wire to ground screw inside the junction box.
D. Replace junction box cover.
3. Thermostat Connections
Thermostat wire connections must be to T and TV screw
terminals on Aquastat.
See wiring diagram,Figure 11a.
4. Multi Zoning
For pump zoning system, see Figures 12 and 13, for zone
valve system, see Figure 14. DO NOT use boiler transformer
to power external accessories like zone valve and relays,
overload and/or burned-out transformer and boiler
malfunction can result.

WATER PIPING
Always follow good piping practices. Observe minimum 25
mm (1") clearance to combustibles around all uninsulated
hot water pipes or when openings around pipes are not
protected by non-combustible materials.
On a hot water boiler installed above radiation level, the
boiler must be provided with a low water cutoff device at
the time of installation by the installer. (see Figure 15 for
piping arrangement)
1. Supply and Return
For tapping sizes see dimensions on page 2. Shut-off
valves are recommended.
2. Circulating Systems
When Victory II boilers are equipped with a water
circulating pump mounted to return the water into the
boiler, this pump location is appropriate for residences
of one or two stories. The alternate pump location
shown in Figure 15 is required in large, multi-story
building installations, especially when high-head pumps
are used.
3. Air Control System
Diaphragm type compression tank is used to control
system pressure. It must be installed at the boiler or
between boiler and supply main pump(s).

VICTORY II VHS MODELS

NOTE: Settings can be checked
using the TEST/SETTINGS Button.
SETTING THE HIGH LIMIT
The high limit is factory set at
88°C (190°F). To adjust, turn the
HI TEMP Dial until the desired
setting is displayed. (Setting
range: 38°C–104°C [100°–220°F])
SETTING THE LOW LIMIT
The low limit is designed to main-
tain temperature in boilers equipped with tankless
coils used for domestic hot water. The low limit is
factory set to OFF. Prior to adjusting, remove the
jumper (not equipped on all units) . Then turn the
LO TEMP Dial clockwise until the desired tem-
perature is displayed. For proper operation, the low
temperature limit setting should be at least 6°C (10°)
below the high limit setting. NOTE: For cold start
operation, the low limit must be turned OFF. IMPOR-
TANT: If low limit temperature cannot be set above
60°C (140°F), remove jumper (Setting range:
OFF or 43°C–93°C [110°-200°F]).
SETTING THE ECONOMY FEATURE
The Economy Feature is factory set for a 1 zone heating system.
To adjust, turn the ECONOMY Dial until the number displayed
equals the number of heating zones. Do not include indirect water
heaters in the number of heating zones. The Economy Feature
conserves fuel by reducing boiler temperature (see “How Thermal
Targeting Works” below). If the heating system is unable to supply
needed heat to the house, the ECONOMY Dial should be turned
to a lower setting (example: In a three zone house, turn the dial to
2 or 1). Conversely, if the boiler provides adequate heat, added
fuel savings can be achieved by selecting a higher setting (exam-
ple: 4 or 5). If the heating and indirect water heater signals were
not separated when wiring the control, the Economy Feature
should be turned OFF to insure the boiler supplies adequate tem-
perature to heat the indirect tank.
ACTIVATING THERMAL PRE-PURGE (OPTIONAL)
NOTE: Activation of this feature is not recommended for boilers
with tankless coils.
Fuel Smart HydroStat has a Thermal Pre-Purge feature to maxi-
mize efficiency. When activated, the control will purge higher boiler
temperatures down to 57°C (135°F) at the start of any thermostat
call and supply the latent energy in the boiler to the heating zone
that is calling. During the purge cycle, the display will indicate Pur.
If the heat is not sufficient to satisfy the thermostat, the control will
energize the burner. This feature works with single- and multi-zone
heating systems utilizing circulators or zone valves. No change in
wiring is needed.
To Activate Thermal Pre-Purge
Push and hold the TEST/SETTINGS button for 20 seconds. The dis-
play will read Pur On. To deactivate the feature, push and hold the
button a second time for 20 seconds. The display will read Pur OFF.
SETTING THE CONTROL
At initial start up, with the Economy Feature active, the control
establishes a 63°C (145°F) target temperature. To test the high
limit shut-off function, the Economy Dial must be turned to OFF.
Once tested, restore the Economy setting. If the heating
demand is high, the target will increase over time to satisfy the
heat load. NOTE: To reduce the potential for condensing, the
control will allow the boiler to heat to 49°C (120°F) prior to
energizing the circulator.
Thermal Targeting technology analyzes thermostat activity
and continually evaluate how much heat the house requires.
When it is very cold outside, the heat demand is high and the
Fuel Smart HydroStat will raise the boiler's Target temperature to
provide needed heat to the home. When the outside tempera-
ture is milder, the heat demand is lower. During these periods,
the Fuel Smart HydroStat will lower the boiler's Target tempera-
ture – saving fuel – while continuing to provide comfort to the
house.

LED LEGEND and TEST/SETTINGS BUTTON
TEMP ACTIVE Indicates that the Fuel Smart HydroStat
control is powered and that the temperature function is active.
TEMP HIGH TEMP Illuminates when the boiler water tem-
perature reaches the high limit setting. It will remain lit until the
water temperature falls 5.5°C (10°F) (see High Limit Differential on
page 4). The Fuel Smart HydroStat prevents burner operation
while this LED is on.
LWCO ACTIVE Indicates that the low water cut-off (LWCO)
function of the Fuel Smart HydroStat is active. When the control
is installed with a Hydrolevel Electro-Well, this LED will be on at
all times when the control is powered.
IMPORTANT: If the control is installed with a well other than the
Electro-Well, this LED will not illuminate indicating that the con-
trol is not providing low water cut-off functionality.
LWCO LOW WATER Illuminates if the boiler is in a low
water condition. The Fuel Smart HydroStat will prevent burner
operation during this condition. IMPORTANT: The system must
be checked by a qualified heating professional prior to resuming
operation.
WARNING: DO NOT ADD WATER UNTIL THE BOILER
HAS FULLY COOLED.
ECONOMY ACTIVE Indicates that the Thermal Targeting
function is active and the Fuel Smart HydroStat will reduce boiler
temperature to conserve fuel. The Economy feature is activated
using the ECONOMY dial. (See “How Thermal Targeting Works”
on page 4 for more information).
ECONOMY TARGET When the Economy feature is active,
the Fuel Smart HydroStat continually sets target temperatures
below the high limit setting to maximize fuel efficiency. When the
boiler water reaches the target temperature, the LED illuminates
and the burner will shut down. The boiler water will continue to
circulate and heat the house as long as the thermostat call con-
tinues. The LED will stay lit until the boiler temperature drops to
the differential set point (see Target Temp Differential on page 4)
at which point the boiler will be allowed to fire again. NOTE: This
LED illuminates regularly during normal boiler operation.

Continued from Page 15
An automatic air vent is used to remove air from the sys-
tem. It should be installed in the top of the boiler as shown
in Figure 15. If system pressure needs furthercontrol, add
an additionaltank in parallel with originaltank or install a
larger capacity tank. Use appropriate size tank for volume
of water in system. See chart for boiler’s volume.
4. Cold Water Fill
Pressure reducing (fill) valve and shut-off valve should be
installed.
5. Relief Valve Discharge Piping
Use same size or larger piping than valve outlet. Must
terminate 6" minimum from floor with a plain (no threads)
end. Place a bucket under pressure relief valve discharge.
Make sure discharge is always visible.DO NOThard-pipe
to drain piping.
6. Providing Protection from Freezing
Anti-freeze is sometimes used in hydronic heating systems
to protect against freeze-up in the event of power failure or
control shutdown when the building is unoccupied. It
should be recognized that unless the building is kept
above freezing temperature by some means, the plumbing
system is not protected. Two types of anti-freeze may be
used: ETHYLENE GLYCOL, used in automobiles, has
desirable properties, but is toxic. Its use may be prohibited
when system water/glycol solution is in contact with a
potable water vessel (as an indirect hot water heater with
built-in heating coils). PROPYLENE GLYCOL is used in
the quick-freeze food industry; it is practically non-toxic. Its
use may be permitted when system solution is in contact
with a potable water vessel. When anti-freeze must be
used, inhibited propylene glycol is recommended. Useful
information on the characteristics, mixing proportions, etc.
of glycol in heating systems is given in Technical Topics
No. 2A, available from the Hydronics Institute, 34 Russo
Place, Berkeley Heights, NJ 07922. Consult glycol
manufacturers for sources of propylene glycol.
7. Water Treatment
A good water treatment program will not only extend the
useful life of this boiler but it will also save much of the
time and expense of repairs made necessary by
preventable occurrences. A reputable water treatment
company should be consulted to evaluate and determine
the best overall treatment program for your boiler
equipment.
PIPING A HEATING - COOLING SYSTEM TO A WATER
BOILER AND CHILLER
Figure 16 illustrates a method of piping a heating-cooling
system to a water boiler and a chiller. Hand valves (shown) or
automatic valves must be installed to prevent circulation of
chilled water in the boiler or hot water in the chiller.
The air control system and pressure control system must
operate with chiller only, or the boiler only, being valved to the
piping system. Separate control devices on the boiler and
chiller may be used, or a single set of air and pressure
controls on the common piping may be preferred.
If the boiler is used to supply hot water to heating coils in air
handling units, flow control valves or other devices must be
installed to prevent gravity circulation of water in the coils
during the cooling cycle.
OPERATING INSTRUCTIONS, BASIC
1. Filling and Venting Water Systems
A. Fill the system with water. Vent or purge of air.
B. Fire the boiler as soon as possible (see the following
warning and instructions) and raise the water
temperature in the system.
C. Vent air and add water as needed to achieve operating
pressure on boiler gauge. Pressure must be between
approximately 83 kPa (12 psi) (cold water) and 172 kPa
(25 psi) at water temperature setting of high limit
control, for boilers equipped with 207 kPa (30 psi) relief
valves. Boilers rated for a higher pressure and
equipped with a matching relief valve may operate at a
higher pressure, but no higher than 34 kPa (5 psi)
below the relief valve opening pressure.
D. Check for and repair any leaks before placing system
in service.
BEFORE FIRING BOILER, make these checks:
1. System is full of water. Air is vented or purged.
2. Relief valve is installed in accordance with ASME Boiler

LARGE WATER VOLUME SYSTEMS
A boiler by-pass loop, three way valve arrangement, primary
secondary pumping (with a boiler loop) or other acceptable
method, must be used to provide a minimum 130˚ return
water temperature to the boiler. This will prevent condensa-
tion on the cast-iron sections that can result in poor combus-
tion and damage to the boiler.
