B. PRE-INSTALLATION
Ajax Boiler Inc. strongly recommends that this manual be
reviewed thoroughly before installing your Triton Series™
high efciency boiler. The factory warranty does not apply
to boilers that have been improperly installed or operated
(Refer to the warranty in chapter 8). If, after reviewing this
manual, you still have questions not covered in this manual,
please contact the manufacturer or your local Ajax Boiler
Inc. representative.
This section is intended to provide guidance in planning,
design, construction and preparing the space prior to physi-
cal installation of the boiler, its venting, and the necessary
electrical and plumbing connections.
!
NOTE:
The installation must conform to the requirements of the
authority having jurisdiction or, in the absence of
such requirements, to the National Fuel Gas Code, ANSI
Z223.1/NFPA 54, and/or Natural Gas and Propane
Installation Code, CAN/CSA B149.1.
The boiler must not be installed on carpeting.
Local and state codes requiring greater clearances super-
sede these minimum clearances.
• Multiple appliances may be installed side by side with
6” clearance between adjacent appliances to allow
sufcient air for the pilot blower. It is recommended to
maintain 16” clearance between adjacent boilers to
allow access for service to the rear of the unit.
• The minimum clearance between a Triton Series™
boiler and a storage tank is 6”. For alcove installa-
tions, the minimum clearance to combustible con-
struction is 6” to side, 24” to rear walls and 22” from
top of the unit to the ceiling. The front alcove shall
remain open. This will allow boiler to be serviced in its
location without movement or removal of the unit.
B.1. DETERMINING UNIT LOCATION
The boiler should be mounted on a level, structurally sound
surface. The boiler is not approved for mounting on a
combustible surface and Gas fueled equipment installed
in enclosed parking garages must be located at least 18”
above the oor.
The optimal location for the boiler is as close to an exterior
wall as possible to reduce vent loss and to minimize costly
stainless steel ue venting. Maintain minimum specied
clearances for adequate operation. All installations must
allow sufcient space behind the boiler to service vent con-
nections, water pipe connections, piping and other auxiliary
equipment, as well as the appliance.

!
CAUTION:
• Locate the unit so that the condensate can be treated
and piped to meet city and local code requirements.
• The boiler shall be installed such that the gas ignition
system components are protected from water (drip-
ping, spraying, rain, etc.) during boiler operation or
service (circulator replacement, control replacement,
etc.)
• Keep the area around the unit(s) free from combus-
tibles and ammable liquids.
• It is highly recommended that you allow sufcient
space in front and the rear of the unit for replacement
and adjustment of all parts requiring such attention.
B.1.a. Outdoor Installations (Optional)
!
CAUTION:
Triton Series™ boilers are available for certied outdoor
installations.
• Boilers must not be installed under an overhang that
is less than 3’ from the top of the vent terminal.
• Three sides must be open in the area under the
overhang.
• Roof water drainage must be diverted away from
boiler(s) installed under overhangs.
B.1.b. Installations at Elevation.
Rated inputs are suitable for up to 2,000 ft.. elevation
without de-rating. Consult the factory for installations over
2,000 ft.. above sea level. No hardware changes are re-
quired to the unit. (Adjustments may be required).
B.2. CONNECTION INFORMATION
!
NOTE:
The boiler, when used in connection with a refrigeration
system, must be installed so the chilled
medium is piped in parallel with the boiler with appropri-
ate valves to prevent the chilled medium from
entering the boiler.
The boiler piping system of a hot water boiler connected
to heating coils located in air handling
units where they may be exposed to refrigerated air circu-
lation must be equipped with ow control valves
or other automatic means to prevent gravity circulation of
the boiler water during the cooling cycle.
All plumbing and electrical connections are conveniently
made at the rear of the boiler without the need to remove
any panels or components.

B.3. COMBUSTION AND VENTILATION AIR
!
WARNING:
• The lack of adequate combustion air is the single
biggest operating problem encountered with gas
fired water boilers.

B 5
• Use of the boiler in construction areas where ne
particulate matter, such as concrete dust or drywall
dust, is present may result in damage to the boiler
that is not covered by the warranty. If operated in a
construction environment, a clean source of combus-
tion air must be provided directly to the boiler.
• Your Triton Series™ boiler is equipped with a lter to
help prevent such an occurrence above and must be
checked at least every month. A single replacement
lter is located inside the control box.
B.3.a. Indoor Units (Standard)
The boiler must be supplied with sufcient quantities of
non–contaminated air to support proper combustion and
equipment ventilation. Triton Series™ boiler combustion air
can be taken using the boiler room air or may be vented
directly outside.
It is generally recommended to take combustion air from a
well ventilated boiler room whenever possible. However
when using direct combustion air venting, the boiler is ca-
pable of up to 30 ft. of equivalent venting. If more than 30 ft.
of equivalent venting is required, an enlarged vent diameter
may be used to extend maximum vent lengths, but must be
properly sized to allow for sufcient combustion air to be
supplied to the boiler.
All installations must comply with the requirements of the
National Fuel Gas Code, NFPA 54, Canada B149, and all
local codes.
!
NOTE:
• In calculating free area, the required size of the open-
ing for combustion, ventilation, and dilution air shall
be based on net free area of each opening. If free
area through a design of louver or grill is known, it
shall be used in calculating the size opening required
to provide the free area specied. For additional infor-
mation, refer to the latest NFGC code requirements.
• Provisions for combustion and ventilation air must be
in accordance with Air for Combustion and Ventilation,
of the latest edition of the National Fuel Gas Code,
ANSI Z223.1. In Canada the latest edition of CGA
Standard B149 Installation Code for Gas Burning Ap-
pliances and Equipment, or applicable provisions of
the local building codes.
• In order to protect electrical components, the boiler
room ambient air temperature shall not exceed 100oF.
• The equipment room MUST be provided with prop-
erly sized openings to assure adequate combustion
and ventilation air when unit is installed with a basic
Category IV venting system.
• Note: All additional gas red equipment should be
considered when calculating the necessary air supply.
B.3.b. Direct Vent (Ducted Combustion Air)
If outside air will be drawn through the intake vent directly
to this unit for combustion:
• The exhaust vent must be installed with a slight upward
slope of not more than ¼ inch per foot of horizontal run
to vent terminal.
• The exhaust vent must be insulated through the length
of the horizontal run.
• Intake and exhaust vents with vertical termination
should have a rain cap installed.
• It is recommended to install a drain on the exhaust
vent.
• In cold climates, and to mitigate potential freeze up,
Ajax Boiler Inc. highly recommends the installation of a
motorized sealed damper to prevent circulation of cold
air through the boiler during the non – operating hours.
When installing motorized damper actuator with switch
contacts, prove the damper is fully open to prevent unit
from ring when damper is not fully open.
B.3.c. Conventional Combustion Air Supply
U.S. Installations
All Air from inside the building
If all combustion air is drawn from inside the building and
the mechanical equipment room does not receive air from
outside, the following applies:
• The mechanical room must be provided with two
permanent openings communicating directly with ad-
ditional room(s) of sufcient volume so that the com-
bined volume of all spaces meets the criteria for an
unconned space. (An unconned space is dened as
a space whose volume is more than 50 cubic feet per
1,000 BTUH of the aggregate input rating of all appli-
ances installed in that space. (NFGC).
• Each opening must have a minimum free area of 1
sq. in. per 1,000 BTUH of the total input rating of all
gas utilization equipment in the mechanical room.
• One opening must commence within 12” of the top, and
one opening must commence within 12” of the bottom
of the room.
In cold climates, and to mitigate potential freeze up,
A
ce Heating Solutions, LLC highly recommends the
installation of a motorized sealed damper to prevent
circulation of cold air through the boiler during the non –
operating hours. When installing motorized damper
actuator with switch contacts, prove the damper is fully
open to prevent unit from firing when damper is not fully
open.

B 6
!
NOTE:
Ajax Boiler Inc. recommends that one opening shall com-
mence with 6” from the top and one opening shall com-
mence 6” from the bottom. The combined area of the two
openings should not be less than 200 sq. in. for the rst
100,000 BTUH boiler input, and 100 sq. in. for each ad-
ditional 100,000 BTUH boiler input.
All Air from Outdoors
If all the combustion air is drawn from the air outside the
building, and the mechanical equipment room directly com-
municates with outdoor air, either of the following methods
can be used:
Method 1
• The mechanical equipment room must be provided with
two permanent openings. One commencing within 12”
of the top and one commencing within 12” from the bot-
tom of the room.
• The openings must communicate directly, or by ducts,
with the outdoors
• Each opening must have a minimum free area of 1 sq.
in. per 4,000 BTUH of all equipment in the room when
the opening is communicating directly with the outdoors
or through vertical ducts. The minimum free area re-
quired for horizontal ducts is 1 sq. in. per 2,000 BTUH
of the total input rating to all the equipment in the room.
(For addition information, refer to the latest NFGC)
Method 2 (normally applied in cold climate regions):
• The mechanical equipment room must be provided with
at least one permanent opening, commencing within
12” of the top of the enclosure.
• The opening must communicate directly or by ducts
with the outdoors.
• The opening must have a minimum free area of 1 sq.
in. per 3,000 BTUH of the total input rating of all equip-
ment in the room, or no less than the sum of the areas
of all vent connectors in the conned space.
(For additional information, refer to the latest NFGC)
!
WARNING:
Do not use the “one permanent opening” method if the
equipment room is under negative pressure conditions
or the equipment is common vented with other gas red
appliances.
Louvers and grilles.
!
NOTE:
The required size openings for combustion, ventila-
tion and dilution air shall be based on the net free area
of each opening. Where free area through a louver or
grille design is known, it shall be used in calculating the
size opening required to provide the free area specied.
Where the louver and grille design, and free area are not
known, it shall be assumed that wood louvers will have
25% free area, and metal louvers and grilles will have
75% free area (NFGC).
Canadian Installations
!
CAUTION:
All combustion air must be drawn from the outside air of
the building; the mechanical equipment room must com-
municate directly with outdoor air.
!
WARNING:
Care must be taken to ensure that the equipment room is
not under negative pressure conditions.
• Ventilation of the space occupied by the boiler shall
be provided by an opening(s) for ventilation air at
the highest practical point communicating with the
outdoors. The total cross-sectional area of such an
opening(s) shall be at least 10% of the area required
in (2) below, but no less than 10 sq. in.
• For boilers using a barometric damper vent system
there shall be a permanent air supply opening(s)
having a cross section area of not less than 1 sq. in.
per 7,000 BTUH up to and including 1 million BTUH,
plus 1 sq. in. per 14,000 BTUH in excess of 1 million
BTUH. This opening(s) shall be located at or ducted
to a point no more than 18” nor less than 6” above
oor level. The duct can also “goose neck” through
the roof. The duct is preferred to be straight down
and terminated 18” from the oor, but not near the
piping. This air supply opening requirement shall be
in addition to the air opening for ventilation air re-
quired in (1). (above)
For additional information, refer to CGA, B149
B.4. CONVENTIONAL FLUE VENTING
!
CAUTION:
Proper ue venting is critical for the safe and efcient
operation of the boiler.
A
ce Heating Solutions, LLC recommends that one opening
shall commence with 6” from the top and one opening shall
commence 6” from the bottom. The combined area of the two
openings should not be less than 200 sq. in. for the first
100,000 BTUH boiler input, and 100 sq. in. for each additional
100,000 BTUH boiler input.

B 7
Definition of ANSI Categories for High Efficiency
Appliances
• Boilers are divided into four vent type categories based
on the pressure produced in the exhaust and the likeli-
hood of condensate production in the vent. Atlas™
Triton Series™ Boilers require Category IV venting.
(See NFGC, NFPA 54, Section 7 “Venting Equipment”
for more detailed information).
• Category IV: A boiler which operates with a positive
vent pressure and with a gas temperature that may
cause excessive condensate production in the vent.
!
NOTE:
This denition applies to the appliance and does not
necessarily reect the performance of the connected vent
system.
• For additional information on appliance categoriza-
tion, see appropriate ANSI Z21 Standard and the
NFGC (US), or CGA (Canada) B149, or applicable
provisions of local building codes.
• Triton Series™ boilers are designed to operate with a
chamber pressure of 0 to +0.5” WC. The boiler is ca-
pable of 100 feet of vertical equivalent exhaust when
equipped with the standard exhaust vent. When more
than 100 feet of exhaust venting is used, the cham-
ber pressure could increase beyond the maximum
designed +0.5” WC. An optional enlarged vent may
be used to increase vent runs in case more than the

C. INSTALLATION
!
WARNING:
• Altering any Atlas™ Triton Series™ boiler’s pressure
vessel by installing replacement heat exchangers,
tube bundles, coils or any ASME parts not manufac-
tured and/or approved by Ajax Boiler Inc. will instantly
void the ASME and E.T.L. rating of the vessel and
any warranty on the vessel. Altering the ASME or
E.T.L. ratings of the vessel also violates national,
state, and local codes.
• Installation and service must be performed by a quali-
ed installer, service agency or gas supplier.
• Improper installation, adjustment, alteration, service
or maintenance can cause property damage, per-
sonal injury, loss of warranty, exposure to hazardous
materials or loss of life. Review the information in this
manual carefully.
• Make sure the gas on which the boiler will operate is
the same as that specied on the boiler rating plate
(natural gas/propane).
• Caution when servicing gas train components. Pro-
pane (LPG) is heavier than air and may be trapped
in pipes, vents, combustion chamber, or other areas.
Always handle with care.
• Should overheating occur or if the gas supply valve
fails to shut, do not turn off or disconnect the electri-
cal supply to the boiler. Instead, shut off the gas sup-
ply at a location external to the boiler.
• Do not use this boiler if any part has been under
water. Immediately call a qualied service technician
to inspect the boiler and to replace any part of the
control system or any gas control which has been
under water.

serious injury, re, or damage to the boiler:
1. Always keep area around the unit(s) free of chlo-
rine, combustible materials, gasoline, and other
ammable liquids and vapors.
2. Water to be heated in the boiler should be free
or have low levels of chlorine or other chemicals
or water conditions that would be harmful to the
copper heat exchanger. Boiler room ambient
temperature shall not exceed 100 degrees F.
3. Boiler should never be covered or have any
blockage to the ow of fresh air to the boiler.
• Risk of electrical shock. More than one disconnect
switch may be required to de–energize the equipment
before servicing.
• When servicing ceramic ber based refractory or
insulation blanket, gloves and respirators should
be worn to reduce exposure to airborne refractory
ceramic bers.
!

C.6. GAS SUPPLY
!
DANGER:
Make sure the gas on which the boiler will operate is the
same as that specied on the boiler rating plate (natural
gas/propane).
• The gas line should be a separate line running directly
from the gas meter to the unit, unless the existing gas
line is of ample capacity. Verify the capacity of the
existing gas piping if it is to be used.
• The gas pipe must have a sediment trap ahead of the
boiler connection controls and a manual shut–off valve
located outside the boiler cabinet. It is highly recom-
mended that a union be installed in the gas supply
line adjacent to the boiler for servicing. The maximum
working gas pressure for both natural gas and propane
is 14” WC Keep in mind that an increase in gas pres-
sure, without making additional adjustments, leads to
an increased BTU input and a decreased efciency.
!
WARNING:
A sediment trap MUST be installed on the gas piping for
each gas line.
C.6.a. Testing Gas Line
!
CAUTION:
The boiler must be disconnected from the gas supply
during any pressure testing of the gas supply at test pres-
sures in excess of ½ psi (3.5 kPa).
The boiler must be isolated from the gas supply piping
system by closing its individual manual shut–off valve
during any pressure testing of the gas supply piping
system at test pressures equal to or more than ½ psi (3.5
kPa).
Do not use Teon tape on gas line thread. A pipe com-
pound rated for natural and propane gases are recom-
mended. Apply sparingly only on the male pipe ends,
leaving the two end threads bare.
Gas Piping Leak Test
Upon rst installing the Triton Series™ boiler, it is important
to check the gas line leading up to the unit for gas leaks.
1. Follow the National Fuel Gas Code for instructions on
proper gas line piping and gas leak tests.
2. Measuring gas pressures can help detect leaks in iso-
lated lines. Temporarily install a manometer or pressure
gauge with an upper limit of no more than 5 times the
testing pressure, 5 x 14” WC = 2.6psi for Triton Se-
ries™ boiler installations between the manual gas shut
off on the boiler and supply line’s regulator.
3. Leaving the shut off valve closed on the boiler, open
the supply line momentarily until the installed manom-
eter reads a stable pressure and record the pressure
and ambient temperature.
4. Close the supply line and monitor the gas pressure for
a drop in pressure. The test should be monitored for at
least 10 minutes or ½ hour per each 500 ft3of volume
in the testing pipe.
5. At the end of the monitoring period, record the gas
pressure and temperature. If there is a drop in pres-
sure, a gas leak may be present and should be further
investigated (Note: signicant temperature variations
may cause changes in the gas pressure and should be
retested).
!
NOTE:
Please refer to the latest National Fuel Gas Code for
leak test details. If instructions differ, the Fuel Gas Code
shall supersede the instructions in section D.6.a. of these
instructions.

C 13
C.6.b. Gas Supply Pressure
!
WARNING:
Relieve the pressure in the gas supply line prior to con-
necting the boiler and its manual shut off valve to the gas
supply line. Failure to follow this procedure may damage
the gas valve. Gas valves damaged by high gas pres-
sures are not covered by the warranty.
The boiler and its gas connections must be tested for
leaks before operation of the units.
Input may decrease if gas pressure falls below the values
shown below. The maximum gas supply pressure is 14”
WC for all Triton units. If gas pressure exceeds 14” WC
an intermediate gas pressure regulator of the lockup type
must be installed. If gas pressures less than those pro-
vided below are used, input may be decreased.

Table 2.3.1. Triton Gas Pressure Chart.
!
CAUTION:
If the gas pressures exceed 14” WC, a gas pressure
regulator must be installed prior to the gas connection to
reduce the supply pressure.
When connecting additional gas utilization equipment to
the gas piping, the existing piping must be checked to
determine if it is adequate for the combined load.

The NFGC does not address sizing guidelines for the
common venting of multiple Category IV boilers. When
common venting multiple units together, the venting must
be designed by a professional engineer to ensure the
chamber pressure of each boiler is always below 0.5” WC
at high re.
Vent connectors serving any other appliances shall not
be connected into any portion of the mechanical draft sys-
tems operating under positive pressure. If a Triton boiler
is installed to replace an existing boiler, the vent system
must be veried to be of the correct size and of Category
IV AL29-4C vent material. If it is not, it must be replaced.
!
NOTE:
When an existing boiler is removed from a common
venting system, the common venting system is likely to
be too large for proper venting of the appliances remain-
ing connected to it. At the time of removal of an existing
boiler, the following steps shall be followed with each
appliance remaining connected to the common venting
system placed in operation, while the other appliances
remaining connected to the common venting system are
not in operation.
1. Seal any unused openings in the common venting
system.
2. Visually inspect the venting system for proper size and
horizontal pitch and determine there is no blockage or
restriction, leakage, corrosion and other deciencies
which could cause an unsafe condition.

C 16
3. Insofar as is practical, close all building doors and
windows and all doors between the space in which
the appliances remaining connected to the common
venting system are located and other spaces of the
building. Turn on clothes dryers and any appliance not
connected to the common venting system. Turn on
any exhaust fans, such as range hoods and bathroom
exhausts, so they will operate at maximum speed. Do
not operate a summer exhaust fan. Close replace
dampers.
4. Place in operation the appliance being inspected. Fol-
low the lighting instructions. Adjust thermostat so appli-
ance will operate continuously.
5. Test for spillage at the draft hood relief opening after 5
minutes of main burner operation. Use the ame of a
match or candle, or smoke from a cigarette, cigar, or
pipe.
6. After it has been determined that each appliance
remaining connected to the common venting system
properly vents when tested as outlined above, return
doors, windows, exhaust fans, replace dampers, and
any other gas-burning appliance to their previous con-
dition of use.
7. Any improper operation of the common venting system
should be corrected so the installation conforms with
the National Fuel Gas Code, ANSI Z223.1/NFPA 54,
and/or the Natural Gas and Propane Installation Code,
CAN/CSA B149.1. When resizing any portion of the
common venting system, the common venting system
should be resized to approach the minimum size as
determined using the appropriate tables in Chapter 13
of the National Fuel Gas Code, ANSI Z223.1/NFPA 54,
and/or the Natural Gas and Propane Installation Code,
CAN/CSA B149.1.
C.9.c. Termination
!
CAUTION:
A listed vent cap terminal suitable for connection to the
Category IV vent materials, adequately sized, must be
used to evacuate the ue products from boilers.
The vent termination and cap must be installed as follows:
• Must terminate vertically outside the building at least 2
ft above the highest point of the roof that is within 10 ft.
• Should have minimum clearance of 4 ft horizontally
from, and in no case above or below (unless a 4 ft
horizontal distance is maintained), electric meters, gas
meters, regulators and relief equipment.
• The minimum distance from adjacent public walkways,
adjacent buildings, openable windows and building
openings shall not be less than those values specied
in the National Fuel Gas Code, ANSI Z223.1/NFPA 54
and/or the Natural Gas and Propane Installation Code,
CAN/CSA B149.1.
• Minimum twelve (12) inches above grade plus normally
expected snow accumulation or seven (7) feet above
grade if located adjacent to public walkways.
• DO NOT INSTALL over public walkway where local
experience indicates condensation or vapor from the
boiler creates a nuisance or hazard.
• Minimum three (3) feet above any forced air inlet lo-
cated within ten (10) feet of the vent termination.
• Minimum four (4) feet below, four (4) feet horizontally
or one (1) foot above any door, window or gravity air
inlet.
• Minimum twelve (12) inches from corners of building.
• Flue vents supported only by ashing and extended
above the roof more than 5 ft. should be secured by
guy-wires or braced to withstand snow and wind loads.
C.10. CONDENSATE DRAINS
Each Triton Series boiler contains a condensate drain.
In addition, most vent congurations require a drain “T”
located in the vent piping. Pipe each condensate drain
separately to a oor drain or condensate pump/sump.
!
WARNING:
• Failure to properly pipe the condensate drainage sys-
tem will greatly reduce boiler life. Do not install plugs,
caps or valves on condensate piping.
• Do not manifold boiler condensate drains or vent
drains together.
• Do not crimp condensate lines or reduce drain line
inner diameter size.
• Each condensate drain must contain a siphon/pigtail
or trap to prevent ue gas ow through the conden-
sate piping. The height of the top of the syphon/pigtail
loop or trap shall not exceed the height of the con-
densate drain outlet.
• Do not use material that is not approved for use with
ue gas condensate for condensate piping.
• Use continuous Teon, high temperature resistant sili-
cone tubing, or other tubing material compatible with
ue gas condensate for condensate piping.
• Do not install valves on condensate drain lines.

C 17
• A common condensate pump/sump may be used.
Run separate piping from each condensate drain to
the sump. A common drain may be used to dis-
charge condensate from the sump. Consult pump/
sump manufacturer for compatibility of pump/sump
materials of construction. If a common sump is used,
individual drain lines should be connected such that
one drain cannot back feed into another drain.
• Consult local authorities regarding disposal of ue
gas condensate into public waste water system.
Some jurisdictions require that the condensate be
buffered before discharge. This buffering is commonly
achieved by draining the condensate through a lime-
stone (calcium carbonate) bed. The condensate will
be slightly acidic and range between 3-5 on the pH
scale. Consult Ajax Boiler Inc., or a chemical treat-
ment company regarding buffering systems.
C.11. MODULAR SYSTEM INSTALLATIONS
Multiple Triton Series boilers may be installed together, or
as part of a single, modular lead-lag system. Up to 8 indi-
vidual boilers may be installed using standard controls.
C.11.a. General
• Read and follow all venting, combustion air, water pip-
ing, gas piping and electrical instructions contained in
this manual unless otherwise instructed in this section.
• Design and installation of modular systems should only
be undertaken by skilled and knowledgeable engineers
and contractors.
• Consult Local Building Codes, National Fuel Gas Code,
or NFPA 54/ANSI Z223.1 for restrictions and instruc-
tions for modular boilers.
• Refer to section 2. Pre-Installation for further warn-
ings, cautions, notices and instructions.
C.11.b. Sizing
Consult your system mechanical engineer, or Ajax Boiler
Inc. for recommended number and size of boilers for a
given input.
C.11.c. Venting
This section outlines venting requirements for multiple
boiler installations and should be used in addition to the “
B.3. COMBUSTION AND VENTILATION AIR”and “B.4. CON-
VENTIONAL FLUE VENTING” sections earlier in this manual.
Positive Pressure (Sidewall and Vertical) Venting
!
CAUTION:
DO NOT manifold vent components of multiple boilers
without converting to a negative pressure venting ar-
rangement.
• Positive pressure vent systems cannot be manifolded
together.
• Positive pressure systems can be piped individually
through a common vertical or horizontal chase provid-
ed minimum clearances to combustible materials are
maintained.
• Positive pressure systems can be piped individually
through a common vertical chase so that a single roof
penetration can be made. Each vent termination must
be one (1) foot from all other terminations.
Negative Pressure (Conventional) Venting
!
WARNING:
Installing multiple vent terminations close together pro-
motes frost build up on buildings. To minimize this pos-
sibility, extend the distance from the building to the end of
the vent termination and increase the horizontal distance
between vent terminations.
• Refer to National Fuel Gas Code to determine required
chimney diameter and common venting diameter. Note
that combined input, lateral length and chimney height
affect vent diameter.
• Install a double acting barometric damper with integral
ue spillage interlock.
• Locate boiler(s) with lowest input closest to chimney/
vertical common vent.
• Chimney lining must be acceptable for use with con-
densing ue gases.
• Install a condensate drain to collect any condensate
that may form in the lined chimney or vertical common
vent.
Air Intake Piping
• Consult the system mechanical engineer or intake pipe
manufacturer for common air intake pipe sizing.
• Refer to Figures 11 and 12 for common air intake
guidelines for modular boilers.
• Individual air intake pipes may be used in lieu of com-
mon air intake piping.
• Common air intake straight lengths and  ttings should
be assumed to have the equivalent length the same
as an individual air intake pipe, used for a given boiler
intake pipe diameter.
Consult local authorities regarding disposal of flue
gas condensate into public waste water system.
Some jurisdictions require that the condensate be
buffered before discharge. This buffering is commonly
achieved by draining the condensate through a limestone
(calcium carbonate) bed. The condensate will
be slightly acidic and range between 3-5 on the pH
scale. Consult Ace Heating Solutions, LLC, or a chemical
treatment company regarding buffering systems.
Consult your system mechanical engineer, or Ace Heating
Solutions, LLC for recommended number and size of
boilers for a given input.

D 18
• Position horizontal air intake termination center line be-
low horizontal vent termination’s center line.
• Vertical air intake pipe must terminate at least two (2)
feet above the closest portion of the roof.
• Refer to the Combustion Air section for further warnings,
cautions, notices and instructions.
C.11.d. Water Piping
• Refer to Figures 13 thru 18 for typical water piping for
modular boilers.
• Installing a low water cut-off in the system piping is
highly recommended and may be required by Code, if
not factory mounted on boiler.
• Refer to Table 1 for pressure drop and ow requirements
for each boiler.
• Consult I=B=R Installation and Piping Guide.
• Maintain ½” minimum distance between water piping
and combustible material.
• Refer to Water Piping and Trim section for further warn-
ings, cautions, notices and instructions.
C.11.e. Gas Piping
!
NOTE:
The pressure drop given in Table 1 is for the boiler only.
The pressure drop of each system tting and component
must be added to the boiler pressure drop to determine
the system pressure head requirement. See Table 6 for
tting and component equivalent lengths.
• Refer to National Fuel Gas Code, Local Codes and
Tables 2 through 7 for gas pipe sizing.
• Refer to Gas Piping section for further warnings, cau-
tions, notices and instructions.
C.11.f. Electrical
• Each boiler must be provided with a dedicated fused
disconnect.
• Install wiring and ground boiler in accordance with
requirements of authority having jurisdiction. In absence
of such requirements, reference the National Electrical
Code, ANSI/NFPA 70 and/or CSA C22.1 Electrical Code.
• Refer to Figure 1 for electrical data for each size boiler.
• Refer to the Electrical section for further warnings, cau-
tions, notices and instructions.
!
NOTE:
Do not install boiler and circulator pump on the same
fused disconnect.
C.11.g. Condensate Piping
• Each boiler requires separate condensate drains. In
addition, most venting congurations require separate
condensate drains in the vent system.
• Refer to Section C.10. for additional information on
condensate removal.
