the equipment to facilitate maintenance and a safe
work environment. A 1 inch (25.4 mm) side clearance
is acceptable between all boilers, with the exception of
the VTG-5000 which requires an 8 inch (203.2 mm) side
clearance. Custom congurations may not allow 1 inch
(25.4 mm) side clearance.
* Alternate gas pressure arrangements may apply. Please verify gas pressure ratings for your boiler by viewing the boiler name plate.
** Typical 120 VAC controls allow for a +10% and a -15% voltage uctuation.
***Standard congurations. Alternate voltages available as an option; please consult factory.
Note: All dimensions are approximate and are subject to change without notice.
The use of propane may be allowable with concentrations up to 5% propylene, also referred to as HD5. O-standard grades of propane are not permitted. Contact
factory for more information.

! WARNING
All information in this manual is for
reference and guidance purposes,
and does not substitute for required
professional training, conduct,
and strict adherence to applicable
jurisdictional/professional codes and
regulations.
The discharge from the safety relief
valve must be arranged to ensure
no danger of scalding personnel, or
equipment damage.
Provisions must be made to properly
pipe the safety relief discharge
away from the boiler to the point of
discharge.
No shuto of any kind shall be placed
between the safety relief valve
and the boiler, or in the discharge
pipe between the valve and the
atmosphere. Doing so may cause an
explosion from overpressure.
The hydronic system should never be
ushed while the boiler is attached
to the system since the debris could
accumulate in the boiler and block
water from passing through the heat
exchanger.
Ensure all labels on the boiler are
legible. All connections and safety
devices, both mechanical and
electrical, must be kept clean, with
ease of access for inspection, use and
maintenance.
Do not store or use gasoline or other
ammable vapors and liquids or
corrosive materials in the vicinity of
this or any other appliances.
InstallWater Piping
All water supplies contain some solids, dissolved gases or dissolved minerals.
These may cause corrosion, deposition and/or fouling of equipment.To prevent
these contaminants from impacting boiler performance, valve operation and
general pipe longevity, each location must be analyzed and treated accordingly.
Adhere to the following for water piping installation (See Figure 3 - 4):
1. Manual isolation valves are recommended on both water connections for
ease of service.
2. Install piping so that the boiler is not supporting any additional piping.
3. Install manual purging valves in all loops and zones.
4. Install a pressure-reducing (automatic ll) valve in the cold water ll line
to the boiler system. Check that the proposed operation of zone valves,
zone circulator(s) and diverting valves will not isolate air separator(s) and/
or expansion tank(s) from the boiler. Clearance from hot water pipes to
combustibles must be at least 6 inches (152 mm).
5. When used in conjunction with a refrigeration system, install the boiler
so that the chilled medium is piped in parallel with the boiler with
appropriate valves to prevent the chilled medium from entering the
boiler. If the boilers are connected to heating coils (located in air handling
units where they may be exposed to refrigerated air circulation) such
boiler piping systems must be equipped with ow control valves or other
automatic means to prevent gravity circulation of the boiler water during
the cooling cycle.
6. Include the following in the mechanical equipment in the hydronic
heating system:
»An automatic pressure activated water make up valve with back
ow preventer. It must be set to maintain required Net Positive
Suction Head (NPSH) for re-circulating pumps, a positive system
pressure at the highest point of at least 5-10 PSIG (34.5 - 69 kPa),
and make up water valve should be designed to add water to the
system at the outlet of the boiler and should not be fed directly
into the boiler.
»Air removal equipment, including an air separator and automatic
breather valves, along with a functioning expansion tank . Each
must be designed to system specications.
NOTE:The water connection on the top of the boiler is the outlet connection. The
water connection on the rear of the boiler is the inlet connection.
7. Install ltration to remove particulates if appropriate.
8. Install bypass chemical feeder for corrosion inhibitor maintenance if
appropriate.

INSTALLATION VTG-IOM-2016-1214 SECTION2
2-8
9. Install corrosion coupon holder to assess corrosion
inhibitor performance if appropriate.
10. Before installing aVantage boiler into a hydronic
loop, be sure that the system piping and any other
components of the system are clean and free of debris,
ferrous oxide (magnetite), and any foreign matter.The
hydronic system is completely ushed prior to installing
the boiler itself.
Variable Primary Piping Arrangement
Vantage boilers are designed for installation in variable
primary ow piping arrangements. See Figure 3. Although it
is acceptable to installVantage boilers in a primary-secondary
conguration, it is not required.
Adhere to the following for variable primary piping
arrangements:
1. Variable primary arrangements, sometimes referred
to as full ow systems, send all hydronic water ow
directly through the boiler(s). This arrangement
eliminates temperature mixing associated with
primary-secondary piping, thereby delivering the
lowest temperature water directly to the boiler return
connections, and increasing thermal eciency of the
condensing boiler plant.
2. The Vantage boiler does not have a minimum return
water temperature requirement. Do not install three
way mixing valves or bypass piping as low water
temperature protection is not required.
3. The Vantage boiler heat exchanger will not be harmed
by a low ow or zero ow condition, however, proper
design ow will be required to deliver heat to users and
prevent nuisance high temperature limit trips. Select
pump(s) with sucient total dynamic head for the
pressure drop of the loop at design ow.
4. Motorized isolation valves are used in multiple
boiler primary only arrangements to ensure system
eectiveness. One motorized isolation valve should be
installed per boiler; two-position type actuator, open
or closed. It is acceptable to install the valve on either
the inlet or the outlet piping of each boiler. Motorized
isolation valves are used to eliminate mixing of
unheated supply water resulting from ow through idle
boilers, which causes the active boiler(s) to operate with
higher supply water temperatures that may exceed
manual reset high temperature limits. Proper control
strategy must be used to ensure ow paths in the
hydronic loop and residual heat in the pressure vessel
is adequately dispersed when a burner is disabled.The
valve control system must be capable of leaving the
current lead boiler valve open at all times.
5. Multiple boiler systems should utilize a reverse
return header to properly balance ow across the
boilers. Where reverse return cannot be used, it is
recommended to install a balancing valve per boiler.
Primary-Secondary Piping Arrangement
It is acceptable to install the Vantage boiler in a primary-
secondary arrangement, although this arrangement is not
required. See Figure 4. Primary-secondary arrangements are
used to decouple the water ow of the primary (boiler) loop
from the secondary (system) loop. Temperature mixing occurs
in the shared piping region.
Adhere to the following for primary-secondary piping
arrangements:
1. Typical shared piping methods include closely spaced
tees, a buer tank, or a hydraulic separator.
2. When using closely spaced tees as a decoupling
method, the tees should be separated by four pipe
diameters or less.
3. It is recommended to install the dedicated boiler
circulator on the inlet side of theVantage boiler,
pumping into the return connection. Select pump(s)
with sucient total dynamic head for the pressure drop
of the loop at design ow.
4. Systems with multiple boilers should have a single
common supply and a single common return
connection into the secondary (system) piping. Do
not use separate connections for each boiler into the
secondary piping.
5. Multiple boiler systems should utilize a reverse return
primary header to properly balance ow across the
boilers. Where reverse return cannot be used, it is
recommended to install a balancing valve per boiler.

! WARNING
All information in this manual is for
reference and guidance purposes,
and does not substitute for required
professional training, conduct,
and strict adherence to applicable
jurisdictional/professional codes and
regulations.
Do not use matches, candles, ame or
other sources of ignition to check for
gas leaks.
Failure to ensure the use of
uncontaminated air in this
equipment may be a safety hazard
and damage burner components.
Refer to current codes and standards
on the safe installation and operation
of this equipment, including NFPA
54, National Gas Fuel Code, CAN/CSA
B149 and other jursidictional codes.
4 CAUTION
Some soap used for leak testing is
corrosive to certain types of metals.
Clean all piping thoroughly after
completing the leak check.
Care needs to be taken to eliminate
oxygen from the water system, as
excess oxygen in the system will
reduce the life of any boiler. The
boiler warranty does not cover heat
exchanger replacement due to oxygen
contamination of boiler water.
Heat exchanger failure due to
inappropriate water quality, foreign
matter or debris damage is not covered
under the warranty.
If the piping system attached to this
unit will be chemically cleaned, the
boiler must be disconnected from the
system and a bypass installed so that
the chemical cleaning solution does
not circulate through the boiler.
MeetWater Chemistry Requirements
System water chemistry requirements are as follows:
pH: Range of 8.5 - 10.5
Oxygen: Less than 250 ppb (operating condition)
Total Iron/Copper: Less than 5 ppm
1. Refer to your water conditioning or chemical treatment supplier for
analysis and recommendations for proper.
Corrosion Inhibitor: Capable of maintaining iron corrosion rates
<2 mpy. Due to changing environmental restrictions a non-heavy
metal ALL ORGANIC inhibitor is recommended which is designed for
multi metal systems including ferrous metals and yellow metals such
as copper and brass.
Chloride: Less than 250 ppm
Adhere to the following:
1. Refer to your water conditioning or chemical treatment supplier for
analysis and recommendations for proper system conditions.
2. Follow a program with appropriate monitoring and maintenance of system
water conditions as provided by your water conditioning or chemical
treatment supplier.
3. If RO/DI water is used as a source for hydronic loop water or makeup water,
it must be neutralized to a pH of 8.5 - 10.5 prior to entering the boiler.
Failure to neutralize the RO/DI water will void the pressure vessel warranty
and may cause high general corrosion rates.
The system must have an automatic pH controller to monitor and
log the levels.This must be independent of other chemical feed
systems.
Makeup water pH range must be 7.5 - 8.8; the boiler water must be
maintained within pH range of 8.5 - 10.5.
4. Operate the boiler in a closed-loop system using water or water/glycol
(not requiring a make-up water supply). A large amount of improperly
treated make-up water can cause premature failure of the heat exchanger
resulting from scale build up. Scale build up will reduce the eciency and
useful life of the boiler and is not covered under warranty.
5. For freeze protection, and inhibited propylene glycol is recommended.
The maximum concentration is 60% glycol by volume. Use only solutions
formulated for hydronic heating systems. Do not use automotive glycol.
6. At a minimum, the hydronic uid sghould be checked for glycol
concentration and pH once per year.

INSTALLATION VTG-IOM-2016-1214 SECTION2
! WARNING
Do not terminate venting into an
enclosed area.
Never use open ame or smoke from
a cigarette, cigar, or pipe as a testing
method during boiler installation,
operation, or maintenance.
Foreign substances, such as
combustible volatiles in the
combustion system can create
hazardous conditions. If foreign
substances can enter the air stream,
the boiler combustion air inlet must
be piped to an outside location.
Regular maintenance of the
lter is required (as per the lter
manufacturer’s recommendations) to
maintain the Vantage warranty.
Prevent Oxygen Contamination
There are several ways to prevent boiler water oxygen contamination:
Minimize system leaks to minimize make up water requirement
Do not use open tanks or ttings
Do not use oxygen permeable materials anywhere in the water system
Repair leaks in the system quickly
Eliminate ttings wherever possible
Use air elimination devices in system piping
Eliminate System Air
NOTE:There are no built-in boiler air eliminating features.
Adhere to the following for air elimination:
1. The installation of an air separator and air eliminator (air vent) is required.
2. To prevent scale corrosion in boiler and associated piping, make up water
must be kept to a minimum. This is best achieved by ensuring immediate
repair of all leaks and that system pressure is maintained.
3. If a sealed diaphragm-type expansion tank is used, install an air eliminator
in the hot water piping at the air separator on the suction side of the
system circulators.
4. If an air cushion type expansion tank is used, pipe tank directly into boiler
supply on the suction side of the system circulators.
5. On multi-zoned systems (or a system with both space and domestic water
heating), air elimination must be provided either in the common piping or
on every loop.
6. When the boiler is installed at a higher level than baseboard radiation (if
used), air elimination must be provided directly above the unit.
Fill the BoilerWithWater
To be sure that the boiler is not air-bound, open the pressure-relief valve located
at the rear of the boiler. Leave the relief valve open until a steady ow of water is
observed. Close the valve and nish lling the system.
Install Gas Piping
The Vantage boiler is factory test red and combustion is adjusted per the boiler
data plate and test re sheet.
The gas train components are UL certied to operate at specic gas pressure
requirements.The specic requirements for each boiler are called out on the
boiler nameplate, located on the back of the boiler. Parameters depend on fuel(s)
for which the boiler is designed.

Adhere to the following for gas piping installation:
1. See Table 3 for required natural gas pipe size, based on overall length of
pipe from the meter plus equivalent length of all ttings. Approximate
sizing may be based on 1,020 BTU for 1 cubic foot of natural gas.
2. Piping must be installed such that no piping stresses are transmitted to the
boiler. The boiler cannot be used as a pipe anchor.
3. The boiler and all gas piping connections must be pressure-tested and
checked for leaks before being placed into service. Test with compressed
air or inert gas if possible.
4. The boiler must be disconnected at the boiler manual shuto valve
(located at the end of the supplied gas train) from the gas supply piping
system during any pressure testing of the system at pressures in excess of
1/2 PSIG (14 inch W.C.).
5. Step down gas pressure regulators must be able to handle the turndown
of the boiler plant. A consistent gas pressure must be supplied to boilers at
all times.
6. Gas Piping must be installed in accordance with National Fuel Gas Code,
ANSI Z223.1 1991 or latest addenda and any other local codes, which may
apply.
7. The pipe and the ttings used must be new and free of dirt or other
deposits.
8. Piping must be of the proper size to ensure adequate gas supply. A drip leg
and union connection must be installed upstream of the gas safety shut o
valves and must be a 5 inch (127 mm) minimum length.
9. Connect gas supply line to the open end of the tee on which the drip leg is
installed.
10. When making gas-piping joints, use a sealing compound resistant to
liqueed petroleum gases. Do not useTeon tape on gas line threads.
11. After gas piping is completed and before wiring installation is started,
carefully check all piping connections, (factory and eld), for gas leaks. Use
a soap and water solution.
12. The boiler must be disconnected at the boiler shut o valve from the gas
supply piping system during any pressure testing of the system.
NOTE:Where applicable, the vent line connection on the gas pressure regulator
must be piped to outdoor air by the installer in accordance with the National Fuel
Gas Code, ANSI Z223.1-1991 or latest addenda. In Canada gas installations must
by in accordance with the current CAN/CSA B149.1 and 2 and/or local codes.
13. Fuel trains with the SKP25 actuator are set up for 14”W.C.-5 PSIG natural
gas pressure for all models except the VTG-6000 andVTG-6000DF, which
are set up for 18”W.C.-5 PSIG natural gas pressure.

! WARNING
Cements for plastic pipe are
ammable liquids and should
be kept away from all sources of
ignition. Proper ventilation should
be maintained to reduce the hazard
and to minimize breathing of cement
vapors. Avoid contact of cement with
skin and eyes.
Assure all electrical connections are
powered down prior to attempting
replacement or service of electrical
components or connections of the
boiler.
Do not use the boiler/burner as
support for ducted air piping.
Ducted piping must be supported
independently of the boiler.
Particulate matter or chemicals in
the combustion air supply to the
boiler will cause damage or failure to
the burner and is not covered under
warranty.
14. The SKP25 does not guarantee a“ventless”fuel train for all Vantage models,
even though in some occasions the boilers may be installed this way.
Although the SKP25 has independent certication as a ventless regulator,
the Authority Having Jurisdiction (AHJ) may require a vent line to be
installed on alternate components of the fuel train.
NOTE:The port marked “air” on the SKP25 actuator cannot be used as a gas vent
connection. Connecting a vent line to this port may cause operational issues.
15. Vantage models featuring the Bekaert or Riello burners have pilot
assemblies. For Riello burner congurations, if vent limiters are not allowed
per the AHJ, the pilot regulator will need to be vented accordingly.
16. Vantage boilers with the SKP25 fuel train are in compliance with CSD-1 and
CSA. This conguration is also compliant with IRI, which has been replaced
by GE GAP. NFPA 85 conguration is available as an option to comply with
local codes or regulations that specically require a vent valve.
17. Please note that custom congurations may utilize alternate fuel trains. For
these situations, refer to submittal drawings.
18. Ensure the burner will be supplied with sucient ventilation and
uncontaminated air for proper combustion. Air contaminants include, but
are not limited to, chlorides, halogens, ourocarbons, and construction
dust. Refer to appropriate jurisdictional codes.
Components RequiringVentilation to the Outdoors
The following do not require ventilation to the outdoors, as there is a vent limiter
in use:
Regulator on the gas pilot line (applies to DF/LE models only)
An authority having jurisdiction (AHJ) may not permit the use of a vent limiter
on some or all components. If venting is required, use the following general
guidelines:
Each component must have a separate vent line to the outdoors. Vent
lines must not be manifolded or combined with any other vent or exhaust
systems.
Start with the vent connection size and as soon as it is practical, increase
the pipe size one diameter. For every ten feet of vent, increase the pipe size
one diameter. Never reduce the vent size.
Protect the vent termination from debris, dust and insects. Install the vent
termination above the snow line and point down to prevent ingress of
water. The termination must be a minimum of 3 ft (0.9 m) from a source of
ignition.
The SKP25 regulating gas valve does not require ventilation to the outdoors.
