CHAPTER 1
CHAPTER 1 - PRE-INSTALLATION REQUIREMENTS
1.1. Code Compliance
The PRESTIGE Solo must be installed by a qualied in-
staller in accordance with the following:
• All applicable local, state, national and provin-
cial codes, ordinances, regulations and laws.
• For installations in Massachusetts, code requires
the PRESTIGE Solo to be installed by a licensed
plumber or gas tter, and if antifreeze is utilized,
the installation of a reduced pressure back-ow
preventer device is required in the boiler’s cold
water ll or make up water supply line.
• For installation in Massachusetts, all direct vented
appliances must comply with the guidelines as
outlined in Section 2.8 on page 8.
• The National Fuel Gas Code (NFPA54/ ANSI Z
223.1).
• National Electric Code (ANSI/NFPA 70).
• For installations in Canada - Installation Code for
Gas Burning Equipment (CAN/CSA B149.1), Ca-
nadian Electrical Code Part 1 (CSA C22.1).
• Standards for Controls and Safety Devices for
Automatically Fired Boilers (ANSI/ASME CSD-1),
when required.
The boiler gas manifold and gas controls meet
the safe lighting and other performance re-
quirements as specified in ANSI Z21.13.
NOTICE
1.2. Determining Product Location
The PRESTIGE Solo is certified for indoor,
conditioned space installations ONLY.
Before locating the PRESTIGE Solo check for convenient
locations to:
• Heating system piping
• Venting
• Gas supply piping
• Electrical service
Ensure the PRESTIGE Solo location allows the combus-
tion air/vent piping to be routed directly through the
building and terminate properly outside with a mini-
mum amount of length and bends.
Ensure the area chosen for the installation of the PRESTIGE
Solo is free of any combustible materials, gasoline, or oth-
er ammable liquids.
Failure to remove or maintain the area free
of combustible materials, gasoline, or oth-
er flammable liquids or vapors can result in
substantial property damage, serious injury,
or death.
Ensure the PRESTIGE Solo and its controls are protected
from dripping or spraying water during normal opera-
tion or service.
The PRESTIGE Solo should be installed in a location so
that any water leaking from the boiler, piping connec-
tions, or relief valve will not cause damage to the sur-
rounding area or any lower oors in the structure.

CHAPTER 1
1.3. Boiler Freeze Protection Feature
The ACVMax boiler management system has a freeze
protection feature built in. This feature monitors the
boiler water temperature and responds as follows
when no call for heat is present:
• 46ºF [8ºC] Pump outputs congured to respond to
a CH1 Call are enabled.
• 42ºF [6ºC] Pump outputs congured to respond to
a CH1 or CH2 Call are enabled, Burner operates at
low re.
• 60ºF [15ºC] Freeze protection ends. Burner & all
pumps turn o after completing CH Post Pump Time.
• The boiler freeze protection feature is dis-
abled during a hard lockout. The burner
will not fire, but the circulators will operate.
• The boiler freeze protection feature is de-
signed to protect the boiler, not the heating
system. The boiler should be installed in a
primary/secondary piping arrangement if it
is installed in an unheated space or exposed
to water temperatures of 46ºF or less. Refer
to Chapter 4 for primary/secondary and
Chapter 10 for antifreeze guides.
• Failure to comply can result in minor prop-
erty damage, or injury.
1.4. Boiler Replacement
If the PRESTIGE Solo is replacing an existing boiler, the
following items should be checked and corrected prior
to installation:
• Boiler piping leaks and corrosion.
• Proper location and sizing of the expansion
tank on the boiler heating loop.
• The existing vent system is appropriate for the
PRESTIGE Solo and it is correctly installed. Refer
to the PRESTIGE Vent Supplement for the vent
system requirements.
• Amount and quality of propylene glycol within
the system, if applicable.
1.5. Recommended Clearances
The PRESTIGE Solo is approved for zero clearance to
combustibles, excluding vent and boiler piping.
CAUTION
CHAPTER 1 - PRE-INSTALLATION REQUIREMENTS
• Boiler piping must be a minimum 1/4 inch from
combustible materials.
• Reference the PRESTIGE Vent Supplement for
vent pipe clearance requirements.
It is recommended that the following clearances
be maintained for serviceability:
• 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]
When maintaining less than recommended
service clearances, some product labeling, in-
cluding the rating label, may become hidden
and unreadable.
• If the recommended clearances list-
ed above cannot be maintained
or the enclosure in which the boil-
er is installed is less than 85 cubic
feet, the space must be ventilated.
See Section 2.2 on page 4.

2.1. Combustion Air Contamination
If the PRESTIGE Solo combustion air inlet is
located in an area likely to cause or contain
contamination, or if products which could con-
taminate the air cannot be removed, the com-
bustion air must be repiped and terminated at
another location. Contaminated combustion
air will damage the unit and its burner system,
and can result in substantial property damage,
serious injury, or death.
• Do not operate the PRESTIGE Solo if the
combustion air inlet is located near a laun-
dry room or pool facility. These areas will
always contain hazardous contaminants.
• Pool, laundry, common household, and
hobby products often contain fluorine or
chlorine compounds. When these chem-
icals pass through the burner and vent
system, they can form strong acids. These
acids will corrode the heat exchanger,
burner components, and vent system,
causing serious damage and possible
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 must pipe the combustion
air inlet to an area free of these chemicals,
as indicated in Chapter 5 on page 25.
• Failure to comply with these instructions
will result in substantial property dam-
age, serious injury, or death

CHAPTER 2 - COMBUSTION AIR & VENTING
2.2. Ventilation and Combustion Air Require-
ments - Direct Vent
A Direct Vent appliance utilizes uncontaminated out-
door air piped directly to the appliance for combustion.
For Direct Vent installations involving only the PRES-
TIGE Solo, in which the minimum service clearances are
maintained as listed in Section 1.5 on page 2, no
ventilation openings are required, but may be neces-
sary to equalize the air pressure with the outside.
For Direct Vent installations involving only the PRESTIGE
Solo, in which the minimum service clearances are not
maintained as listed in Section 1.5 on page 2, the
space / enclosure must provide two openings for venti-
lation. 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 oor of the space.
For installations in which the PRESTIGE Solo shares the
space with air movers (exhaust fan, clothes dryers, re-
places, etc.) and other combustion equipment (gas
or oil) the space must be provided with adequate air
openings to provide ventilation and combustion air to
the equipment. To properly size the ventilation / com-
bustion air openings, the installer must comply with the
National Fuel Gas Code (NFPA 54 / ANSI Z223.1) for in-
stallations in the U.S. or CAN/CSA B149.1 for installations
in Canada.
The space must be provided with ventilation
/ combustion air openings properly 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 PRESTIGE Solo, excluding the in-
put of a Direct Vent PRESTIGE Solo which uses
combustion air directly from the outside,
thus additional free area for the openings is
not required. Failure to provide or properly
size the openings can result in substantial
property damage, serious injury, or death.
WARNING
2.3. Ventilation and Combustion Air Require-
ments - Category IV
A Category IV appliance utilizes uncontaminated indoor
or outdoor air surrounding the appliance for combus-
tion.
In order to reduce the potential risks associated
with indoor contaminates (see list in Section
2.1 on page 3), flammable vapors and tight
housing construction with little or no infiltration
air, it is recommended to pipe uncontaminated
combustion air directly from the outdoors to
the appliance. This practice also promotes high-
er system efficiency by reducing heated indoor
air from being exhausted from the house and
replaced by cold infiltration air into the house.
For installations in which the PRESTIGE Solo shares the
space with air movers (exhaust fan, clothes dryers, re-
places, etc.) and other combustion equipment (gas
or oil) the space must be provided with adequate air
openings to provide ventilation and combustion air to
the equipment. To properly size the ventilation / com-
bustion air openings, the installer must comply with
the National Fuel Gas Code (NFPA 54 / ANSI Z223.1) for
installations in the U.S. or CAN/ CSA B149.1 for installa-
tions in Canada.
The space must be provided with ventilation
/ combustion air openings properly sized for
all make-up air requirements (exhaust fans,
clothes dryers, fireplaces, etc.) and the total
input of all appliances, including the PRES-
TIGE Solo when located in the same space.
Failure to provide or properly size the open-
ings can result in substantial property dam-
age, serious injury, or death.

2.5. Combustion Air and Vent Piping
The PRESTIGE Solo requires a Category IV venting sys-
tem, which is designed for pressurized venting and
condensate.
The PRESTIGE Solo is certied as a Category IV or Direct
Vent (sealed combustion) appliance. A Category IV ap-
pliance utilizes uncontaminated indoor or outdoor air
surrounding the appliance for combustion. A Direct Vent
appliance utilizes uncontaminated outdoor air piped di-
rectly to the appliance for combustion.
Do not install the PRESTIGE Solo into a com-
mon vent with any other gas or oil appliances.

mon venting system, the common venting system
is likely to be too large for proper venting of the re-
maining appliances. 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.
BEST PRACTICE
DANGER
WARNING
NOTICE
BEST PRACTICE
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.
3. Insofar as is practical:
• Close all exterior building doors and windows
and all doors between the space in which the
appliances remaining connected to the com-
mon 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.
• 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
ame of a match or candle, or smoke from a ciga-
rette, cigar or pipe.
6. After it has been determined that each appliance
remaining connected to the common venting sys-
tem properly vents when tested as outlined above,
return doors, windows, exhaust fans, replace
dampers, and any other gas-burning appliance to
their previous condition of use.
7. Any improper operation of the common venting sys-
tem should be corrected so the installation conforms
with the National Fuel Gas Code (NFPA 54 / ANSI
Z223.1) for installations in the U.S. or CAN/CSA B149.1
for installations in Canada. When resizing any por-
tion of the common venting system, the common
