- All applicable local, state, national and
provincial codes, ordinances, regula-
tions and laws.
- For installations in Massachusetts, code
requires the boiler to be installed by a
licensed plumber or gas fitter, and if
antifreeze is utilized, the installation of
a reduced pressure backflow preventer
device is required in the boiler’s cold
water fill or make up water supply line.
- For installation in Massachusetts all direct
vented appliances must comply with the
guidelines as outlined on page 11.
- The National Fuel as Code NFPA54/
ANSI Z 223.1 - Latest edition.
- National Electric Code ANSI/NFPA 70.
- For installations in Canada -“Installation
Code for as Burning Equipment”

ANSI/ASME CSD-1, when required.
The PRESTIGE Solo boiler gas manifold
and gas controls meet the safe lighting and
other performance requirements as speci-
fied in ANSI Z21.13 latest edition.
Determining Product Location
Before locating the PRESTI E SOLO check
for convenient locations to:
- Heating system piping
- Venting
- as supply piping
- Electrical service
Ensure the boiler location allows the combus-
tion air/vent piping to be routed directly through
the building and terminate properly outside with
a minimum amount of length and bends.
Ensure the area chosen for the installation of the
PRESTI E Solo is free of any combustible
materials, gasoline and other flammable liquids.
Failure to remove or maintain the area
free of combustible materials, gasoline
and other flammable liquids or vapors
can result in severe personal injury,
death or substantial property damage.
Ensure the PRESTI E Solo and its controls
are protected from dripping or spraying water
during normal operation or service.
The PRESTI E Solo should be installed in a
location so that any water leaking from the
boiler or piping connections or relief valve will
not cause damage to the area surrounding the
unit or any lower floors in the structure.

clearance to combustibles, excluding vent and
boiler piping.
- Boiler Piping - 1/4 inch from com-
bustible materials.
NOTICE
WARNING

Pre-Installation Items
- Reference the appropriate vent supple-
ment for clearance requirements.
To provide serviceability to the unit it is
recommended that the following clear-
ances be maintained:
Top boiler jacket - 24 inches [610 mm].
Front - 24 inches [610 mm].
Bottom boiler piping - 24 inches [610
mm].
Rear - 0 inches
Sides - 6 inches [153 mm]
If the clearances listed above cannot be
maintained or the enclosure in which the
boiler is installed is less than 85 cubic feet,
the space must be ventilated. See page 6
for ventilation requirements.
When maintaining zero clearance or less
than recommended clearances, some
product labeling may become hidden
and unreadable.
When installing the PRESTIGE Solo in
a confined space, sufficient air must be
provided for proper combustion and
venting and to allow, under normal oper-
ating conditions, proper air flow around
the product to maintain ambient tem-
peratures within safe limits to comply
with the National Fuel Gas Code NFPA
54 - latest edition.

When installing the PRESTI E Solo in a resi-
dential garage, the following special precautions
per NFPA 54/ANSI Z223.1 must be taken:
- Mount the unit a minimum 18 inches
[458 mm] above the floor level of the
garage. Ensure the burner and ignition
devices / controls are no less than 18
inches [458 mm] above the floor level.
- Locate or protect the unit in a manner so it
cannot be damaged by a moving vehicle.
Boiler Freeze Protection Feature
The TriMax boiler management system has a
freeze protection feature built in. This feature
monitors the boiler temperature and responds as
follows when no call for heat is present:
- 46ºF [8ºC] CH (1) & Auxiliary Boiler
Pumps ON
- 42ºF [6ºC] CH (1), Auxiliary Boiler &
System Pumps ON, Burner operates at
low fire
- 60ºF [15ºC] Freeze protection ends.
Burner & all pumps OFF after complet-
ing CH Post Pump Time.
The boiler freeze protection feature is
disabled during a hard lockout, however
the circulators will operate.
The boiler freeze protection feature is
designed to protect the boiler. The boiler
should be installed in a primary/sec-
ondary piping arrangement if it is
installed in an unheated space or
exposed to water temperatures of 46ºF or
less. See Section IV for primary/sec-
ondary piping examples. See Section X

Combustion Air Contamination
If the PRESTIGE Solo combustion air
inlet is located in any area likely to cause
or contain contamination, or if products,
which would contaminate the air cannot
be removed, the combustion air must be
repiped and terminated to another loca-
tion. Contaminated combustion air will
damage the unit and its burner system,
resulting in possible severe personal
injury, death or substantial property
damage.
Do not operate a PRESTIGE Solo if its
combustion air inlet is located near a
laundry room or pool facility. These
areas will always contain hazardous con-
taminants.
Pool and laundry products and common
household and hobby products often
contain fluorine or chlorine compounds.
When these chemicals pass through the
burner and vent system, they can form
strong acids. These acids can create cor-
rosion of the heat exchanger, burner
components and vent system, causing
serious damage and presenting a possi-
ble threat of flue gas spillage or water
leakage into the surrounding area.
Please read the information listed below.
If contaminating chemicals are located
near the area of the combustion air inlet,
the installer should pipe the combustion
air inlet to an outside area free of these
chemicals per SECTION V of this
installation manual.
Potential contaminating products
- Spray cans containing chloro/fluorocar-
bons
- Permanent Wave Solutions
- Chlorinated wax
- Chlorine - based swimming pool chem-

Ventilation and Combustion Air
Requirements - Direct Vent
A Direct Vent appliance utilizes uncontamined
outdoor air (piped directly to the appliance) for
combustion.
For Direct Vent installations, involving only
the PRESTI E Solo, in which the minimum
service clearances are maintained as listed on
page 4, no ventilation openings are required.
For Direct Vent, zero clearance installations
involving only the PRESTI E Solo, the space
/ enclosure must provide two openings for ven-
tilation. The openings must be sized to provide
1 square inch of free area per 1,000 BTUH of
boiler input. The openings shall be placed 12
inches from the top of the space and 12 inches
from the floor of the space.
For installations in which the PRESTI E Solo
shares the space with air movers (exhaust fan,
clothes dryers, fireplaces, etc.) and other com-
bustion equipment (gas or oil) the space must
be provided with adequate air openings to pro-
vide ventilation and combustion air to the
equipment. To properly size the ventilation /
combustion air openings, the installer must
comply with the National Fuel as Code
NFPA 54, ANSI Z223.1 for installations in the
U.S or CSA B149.1 and B149.2 for installa-
tions in Canada.
The space must be provided with venti-
lation / combustion air openings proper-
ly sized for all make-up air requirements
(exhaust fans, clothes dryers, fireplaces,
etc.) and the total input of all appliances
located in the same space as the PRES-
TIGE Solo, excluding the input of a
Direct Vent PRESTIGE Solo which uses
combustion air directly from the outside,
thus additional free area for the open-
ings is not required. Failure to provide
or properly size the openings could
result in severe personal injury, death or
substantial property damage.
Ventilation and Combustion Air
Requirements - Category IV
A Category IV appliance utilizes uncontami-
nated indoor or outdoor air (surrounding the
appliance) for combustion.
In order to reduce the potential risks
associated with indoor contaminates
(listed on page 5), flammable vapors and
tight housing construction (little or no
infiltration air), it is recommended to
pipe uncontaminated combustion air
directly from the outdoors to the appli-
ance. This practice also promotes higher
system efficiency by reducing heated
indoor air from being exhausted from
the house and replaced by cold infiltra-
tion air into the house.
For installations in which the PRESTI E Solo
shares the space with air movers (exhaust fan,
clothes dryers, fireplaces, etc.) and other com-
bustion equipment (gas or oil) the space must

Combustion Air and Vent Piping
The PRESTI E Solo requires a Category IV
venting system, which is designed for pressur-
ized venting and condensate.
The PRESTI E Solo is certified per ANSI
Z21.13 as a Category IV or Direct Vent (sealed
combustion) appliance. A Category IV appli-
ance utilizes uncontamined indoor or outdoor
air (surrounding the appliance) for combustion.
A Direct Vent appliance utilizes uncontaminat-
ed outdoor air (piped directly to the appliance)
for combustion.
In order to reduce the potential risks
associated with indoor contaminates
(listed on page 5), flammable vapors
and tight housing construction (little or
no infiltration air), it is recommended
to pipe uncontaminated combustion air
directly from the outdoors to the appli-

Removal of an Existing Boiler from a
Common Vent System
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 remaining appliances. At the
time of removal of an existing boiler, the fol-
lowing steps shall be followed with each
appliance remaining connected to the com-
mon venting system placed in operation,
while the other appliances remaining con-
nected 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 deter-
mine there is no blockage or restriction,
leakage, corrosion and other deficiencies
which could cause an unsafe condition.
3. Insofar as is practical, close all building
doors and windows and all doors between
the space in which the appliances remain-
ing connected to the common venting sys-
tem 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 fireplace dampers.
4. Place in operation the appliance being
inspected. Follow the lighting instructions.
Adjust thermostat so appliance will operate
continuously.
5. Test for spillage at the draft hood relief
opening after 5 minutes of main burner
operation. Use the flame of a match or can-
dle, or smoke from a cigarette, cigar or pipe.
6. After it has been determined that each
appliance remaining connected to the com-
mon venting system properly vents when
tested as outlined above, return doors, win-
dows, exhaust fans, fireplace dampers, and
any other gas-burning appliance to their
previous condition of use.
7. Any improper operation of the common
venting system should be corrected so the
installation conforms with the National
Fuel as Code, ANSI Z223.1/NFPA 54
and/or CAN/C A B149, Installation codes.
When resizing any portion of the common
venting system, the common venting sys-
tem should be resized to approach the min-
imum size as determined using the appro-
priate tables in Part II of the National Fuel
as Code ANSI Z223.1/NFPA 54 and/or
CAN/C A B149, Installation codes.

Boiler Piping
SECTION IV - Boiler Piping
General 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
PRESTI E Solo from the system piping.
Use a two wrench method when tighten-
ing piping onto the boiler connections.
Use one wrench to prevent the boiler
piping from turning / twisting. Failure
to support the boiler piping and connec-
tions in this manner could cause damage
to the boiler and its components.
Pressure Relief Valve
1. The PRESTI E Solo is supplied with a 30
psi pressure relief valve and must be piped
using the PRV connection as shown in Fig.
5 page 15.
2. To avoid potential water damage to the sur-
rounding area or potential scalding hazard
due to the operation of the relief valve, the
discharge piping:
- Must be connected to the discharge out-
let of the relief valve and directed to a
safe place of disposal.
- Length should be as short and direct as
possible. The size of the discharge line
should not be reduced, maintain the
same size as the outlet of the relief valve.
- Should be directed downward towards
the floor at all times. The piping should
terminate at least 6 inches [153 mm]
above any drain connection to allow
clear visibility of the discharge.
- Should terminate with a plain end, not
with a threaded end. The material of
the piping should have a serviceable
temperature rating of 250ºF or greater.
- Should not be subject to conditions
where freezing could occur.
- Should not contain any shut-off valves
or obstructions. No shut-off valve
should be piped between the boiler and
relief valve.
Failure to comply with the guidelines on
installing the pressure relief valve and
discharge piping can result in personal
injury, death or substantial property
damage.
Low Water Cutoff Device
- The PRESTI E Solo is equipped with a fac-
tory installed pressure switch type Low Water
Cut Off device.
- The minimum operating system pressure
allowable with this device is 10 psig.
- Check local codes if a Low Water Cutoff
Device is required. If so, determine if this
device meets the requirements of the local
codes.
The PRESTIGE Solo control system also
senses the system water temperatures
entering and exiting the heat exchanger
to provide protection against low water
conditions Where local codes and juris-
diction do not accept a pressure device
for low water protection, the jurisdic-
tions may accept these PRESTIGE Solo
integral control functions as a means of
providing low water protection.
