Boiler Piping
SECTION IV - Boiler PipingGeneral Piping Requirements- All
plumbing must meet or exceed all local,
state and national plumbing codes.- Support all piping using
hangers. DO NOT
support piping by the unit or its components.- Use isolation
valves to isolate system com-
ponents.- Install unions for easy removal of the
PRESTIGE Excellence from the systempiping.
- If plastic pipe is used for boiler piping, itmust have a
maximum oxygen diffusionrate of 0.1 mg/liter per day for boiler
andwater heater protection.
Use a two wrench method when tighten-ing piping onto the boiler
connections.Use one wrench to prevent the boilerpiping from turning
/ twisting. Failureto support the boiler piping and connec-tions in
this manner could cause damageto the boiler and its components.
Pressure Relief Valve1. The PRESTIGE Excellence is supplied
with a 30 psi pressure relief valve and mustbe piped using the
PRV connection asshown in Fig. 5 page 15.
2. To avoid potential water damage to the sur-rounding area or
potential scalding hazarddue to the operation of the relief valve,
thedischarge piping:- Must be connected to the discharge out-
let of the relief valve and directed to asafe place of
disposal.
- Length should be as short and direct aspossible. The size of
the discharge lineshould not be reduced, maintain thesame size as
the outlet of the relief valve.
- Should be directed downward towardsthe floor at all times. The
piping shouldterminate at least 6 inches [153 mm]above any drain
connection to allowclear visibility of the discharge.
- Should terminate with a plain end, notwith a threaded end. The
material ofthe piping should have a serviceabletemperature rating
of 250ºF or greater.
- Should not be subject to conditionswhere freezing could
occur.
- Should not contain any shut-off valves orobstructions. No
shut-off valve should bepiped between the boiler and relief
valve.
Failure to comply with the guidelines oninstalling the pressure
relief valve and dis-charge piping can result in personal
injury,death or substantial property damage.
Low Water Cutoff Device- The PRESTIGE Excellence is equipped
with
a factory installed pressure switch type LowWater Cut Off
device.
- The minimum operating system pressureallowable with this
device is 10 psig.
- Check local codes if a Low Water CutoffDevice is required. If
so, determine if this devicemeets the requirements of the local
codes.
The PRESTIGE Excellence control sys-tem also senses the system
water tempera-tures entering and exiting the heatexchanger to
provide protection againstlow water conditions Where local codesand
jurisdiction do not accept a pressuredevice for low water
protection, the juris-dictions may accept these PRESTIGEExcellence

Additional Limit ControlIf a separate LWCO device is required by
cer-tain local jurisdictions or when the boiler isinstalled above
the system piping, the follow-ing guidelines must be followed:
- The LWCO device must be designedfor water installations,
electrode probe-type is recommended.
- The LWCO device must be installed ina tee connection on the
boiler supplypiping above the boiler.
- Wiring of the LWCO device to the PRES-TIGE Excellence is done
directly onto thelow voltage terminal strip, reference Fig.19 page
29 for available terminals for anexternal limit (manual or auto
reset).
If the installation is to comply with ASME orCanadian
requirements, an additional hightemperature limit may be needed.
Consultlocal code requirements to determine compli-ance. The limit
should be installed as follows:
- Install the limit in the boiler supply pip-ing between the
boiler and any isolationvalve.
- Consult heat exchanger for maximumset point of limit.
- For wiring of the limit reference Fig. 19,page 29, using the
external limit/manualreset terminals on the low voltage termi-nal
strip. This will provide a "hard" lock-out requiring a manual reset
of the control.
Backflow Preventer- Use a backflow preventer valve in the
make-up water supply to the unit asrequired by local codes.
Boiler System Piping Applications
It is recommended on all piping applica-tions to utilize a
primary/secondary pip-ing arrangement as a means to providefreeze
protection of the boiler, which isan integral function of the
boiler control.Maintain the minimum boiler flow rate,see Graph 2 on
page 81. For other pip-ing arrangements, contact ACV-TriangleTube
Technical Support or consult otherapproved/recognized design
arrange-ments.
On piping applications utilizing a singlezone or other
recognized piping designarrangements, it is recommended that
theinstaller uses flow/check valves withweighted seats at or near
the appliance toprevent gravity circulation.
Expansion Tank and Makeup WaterEnsure the expansion tank is
properly sized forthe boiler volume (5 gallons [19 L]) and
thesystem volume and temperature.
Undersized expansion tanks will causesystem water to be lost
through the pres-sure relief valve and cause additionalmakeup water
to be added to the system.Eventual boiler heat exchanger failurecan
result due to this excessive makeupwater addition.
The expansion tank must be located as shownin Figs. 9 through 12

the same location as the expansiontank connection to the
system.
Diaphragm Expansion TankAlways install an automatic air vent on
the topof the air separator to remove residual air fromthe
system.
Closed-Type Expansion TankIt is recommended to pitch any
horizontal pip-ing upwards toward the expansion tank 1 inchper 5
feet of piping. Use 3/4” piping for theexpansion tank to allow air
within the systemto rise.
DO NOT install automatic air vents on aclosed-type expansion
tank system. Airmust remain in the system and bereturned to the
expansion tank to pro-vide an air cushion. An automatic airvent
would cause air to be vented fromthe system resulting in a
water-loggedexpansion tank.
CirculatorThe PRESTIGE Excellence is supplied with aBoiler
circulator that provides circulation forcentral/space heating (CH)
and domestic hotwater (DHW) production. See Graph 2 on page81 for
pressure drop and minimum flow ratethrough the boiler.
Sizing Primary PipingSee Figs. 9 through 12 on pages 20 and 21,
forrecommended piping arrangements based onvarious applications.
Size the piping and sys-tem components required in the space
heatingsystem, using recognized design methods.
System Piping - Zone CirculatorsConnect the PRESTIGE Excellence
to the sys-tem piping as shown in Fig. 9 page 20 whenzoning with
zone circulators.
The installer must provide a separate circulatorfor each zone of
space heating.
To ensure an adequate flow rate throughthe PRESTIGE Excellence,
the boilersupply and return piping size must be aminimum of 1
inch.
System Piping - Zone ValvesConnect the PRESTIGE Excellence to
the systempiping as shown in Fig. 10 page 20 when zoningwith zone
valves. The primary / secondary pipingensures that the boiler loop
has sufficient flow.
To ensure an adequate flow rate throughthe PRESTIGE Excellence,
the boiler sup-ply and return piping size must be a min-imum of 1
inch.
System Piping - Through BoilerIn new or retrofit applications in
whichprimary/secondary arrangement is not utilized, thePRESTIGE
Excellence allows this flexibility dueto a lower boiler pressure
drop, see Graph 2 onpage 81.Figure 11, page 21 illustrates a
multiple zonevalve system with a single system/boiler circu-lator.
A by-pass loop with a pressure differentialvalve must be installed
on the system piping.Figure 12, page 21 illustrates a single zone

Boiler PipingSystem Piping - Radiant HeatingThe heat exchanger
design of the PRESTIGEallows operation in a condensing mode. This
fea-ture requires no regulation of the return temperatureback to
the boiler in radiant heating applications.
Due to the construction of the waterheater, do not install the
PRESTIGEExcellence if the boiler piping containsnon-oxygen barrier
tubing if the boilerpiping is considered an “open system”.Exposing
the outer tank of the PRES-TIGE Excellence water heater to
oxygencontamination will lead to prematuretank failure and denial
of the warranty.
The boiler water supply temperature can bemaintained by the
PRESTIGE, eliminatingthe need for a mix system to achieve
thedesired temperature.
It is recommended for the installer to install ahigh temperature
limit to ensure that the primarysupply temperature does not exceed
the maxi-mum allowable temperature for the radiant tub-ing.
Size the system piping and circulator to pro-vide the flow
needed for the radiant system.
To ensure an adequate flow rate throughthe PRESTIGE Excellence,
the boilersupply and return piping size must be aminimum of 1
inch.
The addition of the high temperature limitis important when the
PRESTIGEExcellence has completed a DHW call,which requires a high
primary supplywater temperature.
System Piping - Special ApplicationIf the boiler is used in
conjunction with achilled water/medium system, the boiler
andchiller must be piped in parallel. Installflow/check valves to
prevent the chilled medi-um from entering into the boiler.
If the boiler is used to supply hot water to theheating coils of
an air handler where they maybe exposed to chilled air circulation,
installflow/check valves or other automatic meansto prevent gravity
circulation of the boilerwater during cooling cycles.
System Piping - Multiple Units InstallationIt is recommended to
use a balanced manifoldsystem as the primary / secondary
connectionto the space heating piping.
Maintain a minimum of 6 inches [153 mm] ofclearance between
units to allow for servicing.For the space heating piping refer to
the appli-cations mentioned in this manual or use recog-nized
design methods.
