Boiler Piping
Additional Limit Control
Boiler System Piping Applications
If a separate LWCO device is required by certain local jurisdictions or when the boiler is
installed above the system piping, the following guidelines must be followed:
-
The LWCO device must be designed
for water installations, electrode probetype is recommended.
-
The LWCO device must be installed in
a tee connection on the boiler supply
piping above the boiler.
-
Wiring of the LWCO device to the PRESTIGE Excellence is done directly onto the
low voltage terminal strip, reference Fig.
19 page 29 for available terminals for an
external limit (manual or auto reset).
BEST PRACTICE
It is recommended on all piping applications to utilize a primary/secondary piping arrangement as a means to provide
freeze protection of the boiler, which is
an integral function of the boiler control.
Maintain the minimum boiler flow rate,
see Graph 2 on page 81. For other piping arrangements, contact ACV-Triangle
Tube Technical Support or consult other
approved/recognized design arrangements.
BEST PRACTICE
On piping applications utilizing a single
zone or other recognized piping design
arrangements, it is recommended that the
installer uses flow/check valves with
weighted seats at or near the appliance to
prevent gravity circulation.
If the installation is to comply with ASME or
Canadian requirements, an additional high
temperature limit may be needed. Consult
local code requirements to determine compliance. The limit should be installed as follows:
-
Install the limit in the boiler supply piping between the boiler and any isolation
valve.
-
Consult heat exchanger for maximum
set point of limit.
-
For wiring of the limit reference Fig. 19,
page 29, using the external limit/manual
reset terminals on the low voltage terminal strip. This will provide a "hard" lockout requiring a manual reset of the control.
Expansion Tank and Makeup Water
Ensure the expansion tank is properly sized for
the boiler volume (5 gallons [19 L]) and the
system volume and temperature.
CAUTION
Undersized expansion tanks will cause
system water to be lost through the pressure relief valve and cause additional
makeup water to be added to the system.
Eventual boiler heat exchanger failure
can result due to this excessive makeup
water addition.
Backflow Preventer
-
Use a backflow preventer valve in the
make-up water supply to the unit as
required by local codes.
The expansion tank must be located as shown
in Figs. 9 through 12 on pages 20 and 21 or as
per recognized design methods. Refer to the
expansion tank manufacturer instructions for
additional installation details.

Boiler Piping
Connect the expansion tank to an air separator
only if the air separator is located on the suction side (inlet) of the system circulator.
Always locate and install the system fill connection at the same location as the expansion
tank connection to the system.
System Piping - Zone Circulators
Connect the PRESTIGE Excellence to the system piping as shown in Fig. 9 page 20 when
zoning with zone circulators.
The installer must provide a separate circulator
for each zone of space heating.
Diaphragm Expansion Tank
NOTICE
Always install an automatic air vent on the top
of the air separator to remove residual air from
the system.
To ensure an adequate flow rate through
the PRESTIGE Excellence, the boiler
supply and return piping size must be a
minimum of 1 inch.
Closed-Type Expansion Tank
System Piping - Zone Valves
It is recommended to pitch any horizontal piping upwards toward the expansion tank 1 inch
per 5 feet of piping. Use 3/4” piping for the
expansion tank to allow air within the system
to rise.
Connect the PRESTIGE Excellence to the system
piping as shown in Fig. 10 page 20 when zoning
with zone valves. The primary / secondary piping
ensures that the boiler loop has sufficient flow.
CAUTION
NOTICE
DO NOT install automatic air vents on a
closed-type expansion tank system. Air
must remain in the system and be
returned to the expansion tank to provide an air cushion. An automatic air
vent would cause air to be vented from
the system resulting in a water-logged
expansion tank.
To ensure an adequate flow rate through
the PRESTIGE Excellence, the boiler supply and return piping size must be a minimum of 1 inch.
System Piping - Through Boiler
In new or retrofit applications in which
primary/secondary arrangement is not utilized, the
PRESTIGE Excellence allows this flexibility due
to a lower boiler pressure drop, see Graph 2 on
page 81.
Circulator
The PRESTIGE Excellence is supplied with a
Boiler circulator that provides circulation for
central/space heating (CH) and domestic hot
water (DHW) production. See Graph 2 on page
81 for pressure drop and minimum flow rate
through the boiler.
Figure 11, page 21 illustrates a multiple zone
valve system with a single system/boiler circulator. A by-pass loop with a pressure differential
valve must be installed on the system piping.
Sizing Primary Piping
Figure 12, page 21 illustrates a single zone utilizing the boiler circulator as the system circulator.
See Figs. 9 through 12 on pages 20 and 21, for
recommended piping arrangements based on
various applications. Size the piping and system components required in the space heating
system, using recognized design methods.

Boiler Piping
System Piping - Radiant Heating
NOTICE
The heat exchanger design of the PRESTIGE
allows operation in a condensing mode. This feature requires no regulation of the return temperature
back to the boiler in radiant heating applications.
The addition of the high temperature limit
is important when the PRESTIGE
Excellence has completed a DHW call,
which requires a high primary supply
water temperature.
CAUTION
System Piping - Special Application
Due to the construction of the water
heater, do not install the PRESTIGE
Excellence if the boiler piping contains
non-oxygen barrier tubing if the boiler
piping is considered an “open system”.
Exposing the outer tank of the PRESTIGE Excellence water heater to oxygen
contamination will lead to premature
tank failure and denial of the warranty.
If the boiler is used in conjunction with a
chilled water/medium system, the boiler and
chiller must be piped in parallel. Install
flow/check valves to prevent the chilled medium from entering into the boiler.
If the boiler is used to supply hot water to the
heating coils of an air handler where they may
be exposed to chilled air circulation, install
flow/check valves or other automatic means
to prevent gravity circulation of the boiler
water during cooling cycles.
The boiler water supply temperature can be
maintained by the PRESTIGE, eliminating
the need for a mix system to achieve the
desired temperature.
System Piping - Multiple Units Installation
It is recommended for the installer to install a
high temperature limit to ensure that the primary
supply temperature does not exceed the maximum allowable temperature for the radiant tubing.
It is recommended to use a balanced manifold
system as the primary / secondary connection
to the space heating piping.
Maintain a minimum of 6 inches [153 mm] of
clearance between units to allow for servicing.
Size the system piping and circulator to provide the flow needed for the radiant system.
For the space heating piping refer to the applications mentioned in this manual or use recognized design methods.
NOTICE
To ensure an adequate flow rate through
the PRESTIGE Excellence, the boiler
supply and return piping size must be a
minimum of 1 inch.

when wired to zone relays or other
devices. Refer to the relay manufacturer’s specifications and the thermostat
instructions for additional information
on anticipator setting.
NOTICE
The use of power stealing thermostats
which draw their power from the PRESTIGE can lead to erratic or unpredictable operation.
Thermostat Wiring
The Trimax control has two thermostat call inputs
for multiple zone / temperature systems. This
allows each call to have its own outdoor reset
curve and maximizes the efficiency of the system.

External Wiring
Outdoor Sensor Wiring
External Modulation Control
The PRESTIGE firing rate can be controlled by
an external modulating boiler controller. See
page 62 for external modulation signal wiring
and setup.
The Outdoor Reset function and Warm
Weather Shutdown (WWSD) features require
the connection of the included outdoor temperature sensor. See page 61 for outdoor sensor
installation and setup.
System Sensor Wiring
An optional system temperature sensor can be
placed on the central heating loop to control the
temperature in the central heating loop instead
of the boiler loop. When connected, the PRESTIGE will automatically modulate to maintain
the target temperature in the central heating
loop. The boiler supply temperature sensor will
continue to be used as a high temperature limit.
Domestic Hot Water Wiring
An indirect water heater sensor is prewired to
the low voltage terminal strip on the wiring
panel below the PRESTIGE control module.
Additional Boiler Limits
Additional boiler limits (High Limit, LWCO,
etc.) can be wired into either the Manual Reset
Limit or Auto Reset Limit terminals of the
PRESTIGE. These limit connections will provide a “hard” lockout requiring a manual reset
of the PRESTIGE or a “soft” lockout in which
the PRESTIGE will automatically reset when
the limit resets.
CAUTION
Locate the system temperature sensor
where it can accurately measure the supply temperature to the heating system.
Inaccurate system temperature readings
could lead to overheating or under heating resulting in property damage.
NOTICE
1. Connect the system temperature sensor to
the low voltage terminal strip on the wiring
panel below the PRESTIGE control module, as shown in Fig. 19 on page 29.
Manual Reset Limit and Auto Reset
Limit connections to the PRESTIGE
require a dry contact with no external
voltage present. Ensure no external voltage is present on each set of wires before
connecting to the PRESTIGE. If external voltage is present, the use of an isolation relay is required to prevent damage
to the Trimax controller.
Cascade Wiring
The Trimax control includes the ability to operate up to six boilers together as one without the
need for external controllers. Consult the
PRESTIGE Trimax Control Supplement for
more information.
1. Remove the factory installed jumper wire
on the Manual Reset or Auto Reset terminals that will accept the additional boiler
limit.
2.
Modbus Wiring
The Trimax control includes the ability to communicate with building management systems
(BMS) through a Modbus interface. Consult
the PRESTIGE Trimax Control Supplement
for more information.
Connect the additional boiler limit to the
low voltage terminal strip on the wiring
panel below the PRESTIGE control module, as shown in Fig. 19 on page 29.

Trimax Operation
SECTION IX- Trimax Operation
The Trimax Boiler Management System is designed to be flexible yet easy to use. Trimax monitors and controls the Prestige to provide heat as efficiently as possible. Trimax includes many
advanced features which previously were not available in the Prestige.
•
Two central/space heating (CH) call inputs with separate outdoor reset curves.
•
Domestic Hot Water (DHW) call input with optional priority.
•
EZ Setup feature allows the installer to quickly customize Trimax for each installation.
•
Cascade function allows up to six Prestige boilers to operate together in a single heating system.
•
Modbus interface for integrating with building management systems.
All Trimax features are easy to use through a graphical display where information is presented
either graphically or in plain English, so code charts are not required. Figure 30 shows a Trimax
display example of the Prestige fired for a domestic hot water demand.

PRESTIGE Excellence water heater for
proper guidelines on filling the inner
tank. Failure to comply could result in
damage of the inner tank.
Due to the degradation of inhibitors over time,
antifreeze fluids must be periodically replaced.
Refer to the manufacturer of the antifreeze for
additional instructions.
Use of Antifreeze in the Boiler System
Filling the Boiler System
WARNING
1. Close the boiler drain valve located on the
bottom of the unit and any manual or automatic air vent in the system.
NEVER use automotive or ethylene glycol antifreeze or undiluted antifreeze in
the primary system as freeze protection.
This can cause severe personal injury,
death or substantial property damage if
ignored.
2. Open all system isolation valves.
3. Fill the boiler system to correct system
pressure. Correct pressure will vary with
each application.
Determine the antifreeze fluid quantity using
the system water content volume and following
the antifreeze manufacturer instructions.
NOTICE
The water volume of the PRESTIGE Excellence
is approximately 5 gallons [19 L]. Remember to
include the volume of the expansion tank.
Typical residential system fill pressure is
12 psi. System pressure will increase
when system temperature increases.
Operating pressure of the system should
never exceed 25 psi.
Check with local codes requirements for the
installation of backflow preventers or actual
disconnection from the boiler’s cold water fill
or make up water supply line.
4. Purge air and sediment in each zone of the
boiler system through the purge valve. Open
air vents to allow air to be purged in the zones.
5. Once the system is completely filled and
purged of all air and sediment, check the
system pressure and check/repair any leaks.
NOTICE
NOTICE
Massachusetts Code requires the installation of a backflow preventer if antifreeze
is used.
For proper operation of the air vents
ensure vent cap are tightened at all
times. The air vents are provided with
hydroscopic cap that prevents leakage of
water due to internal membrane.

Start-Up Preparation
WARNING
Unrepaired system leaks will cause continual makeup water to be added to the
boiler. Continual makeup water will
cause mineral buildup within the heat
exchanger, reducing the heat transfer,
causing possible heat buildup and eventual heat exchanger failure.
Check Low Water Cut-Off Device
-
-
The PRESTIGE Excellence is provided with
a factory installed LWCO device that measures system pressure of more than 10 psi.
Remove the front jacket panel and check for
continuity across the low water cut-off
device wire terminals. The contacts should
be closed when system pressure is greater
than 10 psi. See item 6, on Fig. 34 page 74
for location of the LWCO.
-
Close each thermostat, zone valve and
relay in the external circuit one zone at a
time and check the voltage reading across
the wire ends.
-
There should NEVER be voltage measured
at the wire ends.
-
If voltage is measured at the panel under any
condition, check and correct the external
wiring.
In systems using 3-wire zone valves,
backfeed of voltage to the unit is a common problem. Use an isolation relay to
prevent voltage from the external circuit
entering the PRESTIGE Excellence control panel.
-
WARNING
Reconnect the external thermostat
wires to the low voltage terminal strip.
Inspection of Condensate Drain Assembly
Prior to start-up and during initial operation, smell near the floor and around the
unit for gas odorant or any unusual odor.
Do not proceed with the start-up if there
is any indication of a gas leak. Any leaks
found must be repaired immediately.
1. Inspect and ensure the Condensate Drain
Assembly is properly installed as described
on page 22 and shown in Fig. 14 on page 23.
2. Remove the plug from the Condensate
Drain Assembly and fill with fresh water.
WARNING
NOTICE
Propane installations only - The propane
supplier mixes an odorant with the
propane to make its presence detectable.
In some cases the odorant can fade and
the gas may no longer have an odor.
The condensate drain assembly must be
filled with water when the PRESTIGE
Excellence is in operation. The condensate drain assembly prevents flue gas
emissions from entering the condensate
line. Failure to ensure trap is filled with
water could result in severe personal
injury or death.
Prior to start-up of the unit and periodically after start-up have the propane
supplier check and verify the odorant
level.
3. Re-Install plug in condensate drain assembly.
Check Thermostat Circuit
Disconnect the external thermostat wires
from the low voltage terminal strip.

Outdoor Reset Control
SECTION XII - Outdoor Reset Control
4. Avoid mounting the outdoor sensor in areas
subjected to excessive moisture.
The use of the outdoor reset function is
required to optimize boiler efficiency, see
notice below. If the outdoor sensor is not
installed before turning on the boiler, an
Outdoor Sensor Open error (E96) will be displayed. The error will not prevent the boiler
from operating. The error will automatically
reset once the outdoor sensor is installed or if
the outdoor reset function is disabled.
Reference TriMax Operation - EZ Setup section for information on disabling the outdoor
reset function. The outdoor reset function can
only be disabled if the boiler installation meets
one of the exceptions listed in the notice.
5. Once an area on the exterior wall has been
determined, follow the mounting instructions included with the outdoor sensor.
Wiring the Sensor
1. Connect 18 AWG 2-wire cable or similar
cable to the outdoor sensor.
2. Route the cable back to the PRESTIGE
Excellence, ensuring the wires are not run
parallel to telephone or power cables.
NOTICE
Mounting the Outdoor Sensor
If the sensor wires are located in an area
with sources of potential electromagnetic
interference (EMI) the sensor wires
should be shielded or the wires should be
routed in a grounded metal conduit. If
using shielded cable, the shielding should
be connected to the common ground of
the unit.
1. The exterior wall selected for mounting the
outdoor sensor should represent the heat
load of the building. Typically a northern
or northeastern wall will suit most buildings. A southern facing wall for those
buildings, which may have large glass
walls or windows on the southern face.
2. Ensure the outdoor sensor is shielded from
direct sunlight or the effects of heat or cold
from other sources (exhaust fans, appliance
vents...) to prevent false temperature sensing.
3. Connect the outdoor sensor wires to the outdoor sensor terminals on the low voltage terminal strip located inside the boiler enclosure (see Fig. 19 page 29). The outdoor sensor wires do not have polarity.
3. Mount the outdoor sensor at an elevation
on the exterior wall to prevent accidental
damage or tampering.

External Modulating Control
SECTION XIII - External Modulating
Control
Trimax Adjustment
The Trimax control must be programmed to
accept the 0-10 VDC signal from the external
modulating boiler control.
The boiler can directly accept an analog 0-10
VDC signal to control the firing rate from an
external modulating boiler controller such as
the Optima SCC4.
1. Use the Heating EZ Setup function to set
the CH Demand to 0-10V Modulation
Signal. Reference page 43 for the Heating
EZ Setup function.
Wiring the Modulating Controller
Run two 18 gauge wires from the external
modulating boiler controller’s 0-10 VDC boiler output to the modulation signal terminals on
the low voltage terminal strip inside the boiler.
(see boiler wiring diagram, Fig. 19 page 29).
This signal will both enable and modulate the
boiler. No wiring is required at the thermostat
terminals.
Programming of External Modulating
Control
The external modulating control must be programmed to send 2 VDC to enable the boiler
and run it at low fire, and 10 VDC to run the
boiler at high fire. Once the control enables the
boiler, it must wait 30 seconds to allow the burner to stabilize before modulating the boiler.
NOTICE
Ensure that the polarity of the connections from the external modulating boiler controller to the boiler are correct.
Reversed polarity will lead to no
response from the boiler.

Maintenance Procedures
Check Expansion Tank
WARNING
Refer to Section IV - Boiler Piping for recommended location of the expansion tank
and air eliminators.
Before manually operating the pressure
relief valve, ensure the discharge piping is
directed to a suitable place of disposal to
avoid a potential scald hazard. The discharge piping must be full size without
restriction and installed to permit complete drainage of both the valve and line.
Closed -Type Tank:
-
Ensure tank is partially filled with
water leaving an air gap as a cushion.
Refer to the manufacturer’s instruction
for proper fill level.
-
Ensure the tank is fitted with a device
that reduces gravity circulation of airsaturated tank water back into the system. This device prevents air from
bubbling up through the water as it
returns from the system.
-
Ensure no automatic air vents are used
in the system. This will allow air to
escape from the system instead of
returning to the tank.
If after closing the valve, the valve fails to seat
properly or continually weeps, replace the
relief valve. Ensure the cause of the relief
valve to weep is the valve itself, not due to system over-pressurization caused by an expansion tank that is waterlogged or undersized.
Inspection of Ignition Electrode
Remove the ignition electrode from the burner
mounting plate.
Remove any white oxides accumulated on the
electrode using fine grit sandpaper or steel wool.
If the electrode does not clean to a satisfactory
condition, replace the ignitor.
Diaphragm Tank:
-
-
Ensure the system contains a minimum of
one automatic air vent. Recommended
location of the air vent should be atop an
air eliminator.
When replacing the ignition electrode, ensure
the gasket is in good condition and correctly
positioned, replace gasket if necessary.
Remove the tank from the system and
check the charge pressure. For residential applications the charge pressure is
typically 12 psig. If tank does not hold
a charge pressure, then the membrane is
damaged and the tank should be
replaced.
Check Ignition Wiring and Ground Wiring
Inspect the ignition cable from the ignitor to
the Trimax control module.
Check Boiler Relief Valve
Inspect the ground wire from the ignitor to the
boiler jacket ground terminals.
Inspect the relief valve and lift the lever to verify flow at least annually or as recommended
on the warning tag of the valve.
Ensure wiring is in good condition and securely connected.
Check ground continuity of the wiring to the
boiler jacket or piping using a continuity meter.
Replace and correct ground wire if ground continuity is not completed and satisfactory.

Water Heater Maintenance
Check function of field-installed controls
and valves. See component manufacturer’s
instructions.
Maintenance Schedule
Annual service by qualified service technician
should include the following:
Review homeowner’s maintenance responsibilities and their frequencies, including any
not listed in the following section.
Any procedure required by local codes.
Check air vent operation.
Verify system pressure. Air venting procedure may require adding water to bring system up to pressure, typically 12 psig.
Manually operate T&P relief valve at least
once a year. This will release some hot
water.
Homeowner monthly maintenance to include:
Check air vent operation.
•
WARNING
Before operating T&P relief valve, make
sure no one is in front of or around T&P
relief valve discharge piping. Hot discharge
water can cause severe personal injury or
substantial property damage.
Move operating lever to open position for a
few seconds and then move it back, allowing
it to snap closed. After T&P relief valve is
operated, if it continues to release water,
close cold water inlet to water heater immediately. Follow draining instructions, and
replace T&P relief valve. If T&P relief valve
weeps periodically, it may be due to thermal
expansion see Thermal Expansion, page 6.
Do not plug T&P relief valve or discharge
piping.
Automatic air vent - remove cap. Briefly
push in valve and release it to clean valve
seat. Screw cap on completely, then
unscrew one full turn. If air vent does not
operate, call qualified service technician.
Visually check valves, pipes and fittings for
leaks. Call qualified service technician to
repair leaks.
Filling Water Heater
See “Filling the Outer (Boiler Water) Tank” and
“Filling the Inner (Domestic Water) Tank on page
11.
Draining Water Heater
Drain water heater if it will be shut off and exposed
to freezing temperatures. Freezing water will
expand and damage water heater.
•
If boiler water contains sufficient
antifreeze, then only the domestic water
needs to be drained.
WARNING
WARNING
Plugging T&P relief valve or discharge piping can cause excessive pressure in water
heater, resulting in severe personal injury,
death, or substantial property damage.
Follow instructions on circulator to oil it, if
required.
Check mixing valve, valves, pipes and fittings for leaks.
664A0300 - Rev. A
16
Close boiler water isolation valves and
relieve system pressure to below 15 psig in
outer tank before draining inner tank to
prevent damage to inner tank.
•
If boiler water does not contain sufficient
antifreeze, then the boiler water and
domestic water must be drained.
EXCELLENCE_IWH_manual _qrk8:Prestige 9/29/14 11:30 AM Page 19
Water Heater Maintenance
If antifreeze is used in boiler water, check concentration. Boiler water (including additives) must be
practically non-toxic, having toxicity rating or
class of 1, as listed in Clinical Toxicology of
Commercial Products. A maximum 50/50 mixture
of inhibited propylene glycol is recommended.
Follow antifreeze manufacturer’s instruction.
WARNING
Do not use automotive, ethylene glycol or
petroleum-based antifreeze. Do not use
any undiluted antifreeze. This can cause
severe personal injury, death or substantial
property damage.
Draining Inner (Domestic Water) Tank
(See Domestic Piping Fig. 4 page 9)
1. Disconnect power supply to water heater.
- If outer (boiler water) tank pressure is
greater than 15 psig, relieve boiler pressure and close isolation valves before proceeding.
2. Close system supply isolation valve.
3. Connect a hose to domestic water drain valve
at cold water inlet. Hose should extend to
drain at floor level to allow siphoning of
domestic water tank.
4. Open hot water faucet at highest point above
heater.
WARNING
Water from opened drain valves, unions
and other connections may be extremely
hot. To avoid severe personal injury, death
or substantial property damage:
5. Open domestic water drain valve to start
siphoning.
6. When draining is complete, close hot water
faucet and domestic water drain valve.
- Tighten all drain hose connections.
- Direct hot water away from all persons.
Draining Outer (Boiler Water) Tank
1. Disconnect power supply to water heater.
2. Close boiler water isolation valves between
boiler and water heater.
3. Connect hose to boiler water drain valve at
water heater. Open and drain water to a safe
place.
4. To speed draining procedure, loosen air vent
on top of tank.
5. When draining is complete, close drain valve
and retighten air vent.
