SECTIO I - PRE- I STALLATIO
REQUIREME TS
Removal of an Existing Boiler from a Common Vent
System
Do not install the PRESTIGE into a common vent
with any other gas or oil appliances. This will cause
flue gas spillage or appliance malfunction, resulting
in possible severe personal injury, death or sub-
stantial property damage.
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 appli-
ances. 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 remain-
ing 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
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 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 maxi-
mum speed. Do not operate a summer exhaust fan.
Close fireplace dampers.
DA GER
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 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, fireplace
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, ANSI
Z223.1/NFPA 54 and/or CAN/CSA B149.1 ,
Installation Codes. When resizing any portion of the
common venting system, the common venting sys-
tem should be resized to approach the minimum
size as determined using the appropriate tables in
Part 11 of the National Fuel Gas Code, ANSI
Z223.1/NFPA 54 and/or CAN/CSA B149.1,
Installation Codes.

Pre-Installation Require ents
Vent/Combustion Air Piping and Materials
The installation must conform to the requirements of
the authority having jurisdiction or, in the absence of
such requirements, to the ational Fuel Gas Code,
A SI Z223.1/ FPA 54, and/or atural Gas and
Propane Installation Code, CA /CSA B149.1.
The PRESTIGE is certified per ANSI Z21.13 as a
Category IV (indoor air) or Direct Vent (sealed combus-
tion) appliance. A Category IV appliance utilizes uncon-
taminated indoor or outdoor air (surrounding the appli-
ance) for combustion. A Direct Vent appliance utilizes
uncontaminated outdoor air (piped directly to the appli-
ance) for combustion.
To reduce the potential risks associated with indoor
contaminates (listed on page 6), flammable vapors
and tight housing construction (little or no infiltra-
tion air), it is recommended to pipe uncontaminated
combustion air directly from the outdoors to the
appliance. This practice also promotes higher sys-
tem efficiency by reducing heated indoor air from
being exhausted from the building and replaced by
cold infiltration air.
The PRESTIGE requires a Category IV venting system
which is designed for pressurized venting and condensate.
The vent and combustion air materials (piping, fit-
tings and cement) must meet the listed require-
ments in this manual. Failure to comply with these
material requirements could result in severe per-
sonal injury, death or substantial property damage.

- For all venting applications, PVC/CPVC, AL29-4C®,
SS or Polypropylene, the maximum allowable length
should not exceed those lengths listed in Table 8.
- For PVC/CPVC or AL29-4C® vent systems reduce the
maximum allowable length for each elbow as follows:
- 3 Feet for every 45º elbow
- 5 feet for every 90º elbow
- For polypropylene vent systems reduce the maxi-
mum allowable length for each elbow as follows:
- 5 Feet for every 45º elbow
- 10 feet for every 90º elbow
2 Inch (60 mm) Vent Systems Restrictions for the
PRESTIGE 60, 110 & Excellence.
- Derate the maximum boiler input by 3% when using
the maximum equivalent length of 2 inch (60 mm)
vent piping on Solo 110 & Excellence 110.
- The 2 inch vent system requires a 1 inch clearance
to combustibles
- Use long sweep elbow to limit pressure drop and to
avoid excessive vent temperatures.
- In 2 inch PVC vent applications, the first 7 equivalent
feet of the vent system must utilize CPVC material.
To avoid vent failure the installer must use CPVC
vent material for the first 7 equivalent feet of a 2 inch
PVC vent system. The installer must also utilize
primer and glue that is certified for both PVC/CPVC
materials. Failure to properly install the vent system
can lead to carbon monoxide posoning or fire due to
joint separtion or pipe breakage.

3 Inch Vent System Restrictions
- Derate the maximum boiler input of the PRESTIGE
Solo 250 by 3% when using the maximum equiva-
lent length of 3 inch (80 mm) vent piping.
Rigid Polypropylene Vent System Restrictions
Contact approved polypropylene vent manufacturer
for a copy of their installation instructions. Read,
understand and follow all of the vent manufacturer’s
instructions before beginning the installation.
Contact vent manufacturer if you require any techni-
cal support. Failure to properly install and support
vent system can lead to carbon monoxide poisoning
or fire due to joint separation or pipe breakage.
- Rigid polypropylene vent pipe must be installed with
locking band clamps or connector rings and sup-
ports (wall strap or clamp, elbow or base, etc.).
Consult vent manufacturer for complete list of other
parts required.
- Maintain 5/8" per foot slope back toward appliance
on all horizontal runs.
- The use of a wall plate is required to seal rigid
polypropylene vent pipe at the entrance of the chim-
ney or chase to prevent mortar or cement from con-
tacting the polypropylene vent pipe.
- Any termination piping external to the building must
be UV resistant (black).
- Do not apply insulation directly to vent. Maintain
vent manufacturers clearances to combustibles.
- Plastic venting systems shall not pass through rated
fire separations without approved fire stopping
installed in accordance with fire stopping manufac-
turers instructions.
- Prior to assembly of any joints, ensure joint gasket is
present and properly installed. Contact vent manufac-
turer if gasket is missing or damaged. Verify the
integrity of joints upon completion of the vent system.

Combustion Air Contamination
If the PRESTIGE combustion air inlet is located in an
area likely to cause or contain contamination, the
combustion air must be repiped and terminated at
another location. 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 the PRESTIGE if it’s combustion air
inlet is located near a laundry room or pool facility.
These areas will always contain hazardous con-
taminants.
Pool and laundry products, 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 will corrode the heat exchanger,
burner components and vent system, causing seri-
ous damage and presenting possible flue gas
spillage or water leakage into the surrounding area.
Please read the information listed below. If contam-
inating 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.

Direct Vent Installation of Vent/Air Piping
11
SECTIO II - DIRECT VE T I STALLATIO
OF VE T/AIR PIPI G
A Direct Vent appliance utilizes uncontaminated outdoor
air (piped directly to the appliance) for combustion.
Direct Vent - Vertical - Through the Roof or Unused
Chimney
The installation must conform to the requirements of
the authority having jurisdiction or, in the absence
of such requirements, to the ational Fuel Gas
Code, A SI Z223.1/ FPA 54, and/or atural Gas and
Propane Installation Code, CA /CSA B149.1.
When using an inoperative chimney as a means of a
chase for the vent, the surrounding space within the
chimney cannot be used to draw combustion air or
vent another appliance.
A gas vent extending through a roof should not ter-
minate near an adjacent wall or below any building
extensions such as roof eaves, balconies or decks.
Failure to comply with the required clearances in
this manual could result in severe personal injury,
death or substantial property damage.
The information and diagrams outlining the fittings
and method of terminating the vent/combustion air
are directly related to PVC/CPVC vent systems.
When utilizing and AL29-4C® or Polypropylene vent
system there may be some variations. Consult the
appropriate vent manufacturer for recommenda-
tions and clarifications.
Determine Termination Location
Locate the vent and combustion air termination using the
following guidelines:
1. The total length of the vent or combustion air piping
must not exceed the limits given in Table 8 on page 8.
NOTICE
NOTICE
WAR I G
NOTICE
Do not include the two 90ºelbows or tee used to ter-
minate the combustion air inlet exterior of the build-
ing when determining the total length of pipe.
2. The combustion air piping must terminate in an
upside down “U” shape fashion using two 90º
elbows as shown in Fig. 1 page 12 or with a tee as
shown in Fig. 2 page 12. The termination must be
installed 12” [30.5 cm] (18” [45.7 cm] Canada) above
the highest anticipated snow level.
3. The vent must terminate vertically with a coupling to
accept the bird screen and must be located 12” to 24”
[30.5 cm to 61 cm] above the combustion air inlet as
shown in Fig. 1 & Fig. 2 on page 12.
4. The vent and combustion air terminations must be
located a radial distance of 12” to 24” [30.5 cm to 61
cm] from centerline of vent termination to centerline
of air termination as shown in Figs. 1 & 2 on page
12.
5. The following should be considered when deter-
mining the location of the vent and combustion air
terminations:
a. Locate the vent termination where flue vapors
will not damage surrounding shrubs, plants or
air conditioning equipment or be objectionable
to the homeowner.
b. The flue products will form a noticeable plume of
water vapor as they condense in colder air.
Avoid terminating the vent in areas where the
plume could obstruct window views.
c. Prevailing winds could cause freezing of flue
gas condensation and a buildup of water / ice on
surrounding plants, building surfaces or com-
bustion air inlet.
d. Avoid locations where prevailing winds could
affect the performance of the boiler or cause
recirculation of the flue gases, such as inside
corners of buildings, near adjacent buildings,
vertical surfaces, window wells, stairwells,
alcoves, courtyards, or other recessed areas.
e. Do not terminate the vent above doors or win-
dows: flue condensate could freeze causing ice
formations.
f. Locate the vent termination to prevent possible
condensate damage to exterior finishes.
g. Avoid locations of possible accidental contact of
flue vapors with people or pets.

Direct Vent - Vent Installation - Through the Roof
1. Vent and Combustion Air Penetration
- Vent pipe penetration through combustible or
non-combustible wall material should maintain a
minimum 1/4” [6 mm] clearance for 3” and 4”
PVC/CPVC vent or 1” [2.5cm] for 2” PVC/CPVC
vents. The diameter of the penetration hole
should be 4” [10.2 cm] minimum for 2” and 3”
pipe or 5” [12.7 cm] minimum for 4” pipe. When
using Polypropylene or Stainless Steel Vent
refer to vent manufacture’s installation instruc-
tions, supplied with the vent for clearances.
- Combustion air pipe penetration can maintain
zero clearance. The diameter of the penetration
hole should be 2-3/8” [6 cm] minimum for 2” pipe
or 3-1/2” [8.9 cm] minimum for 3” pipe or 4-1/2”
[11.4 cm] minimum for 4” pipe.
2. The installer must use a galvanized metal thimble for
the vent pipe penetration.
3. Locate the vent and combustion air pipe penetra-
tions to provide clearances as described in Fig. 1 &
Fig. 2 on page 12.
4. The installer must comply with all local codes for iso-
lating the vent and combustion air pipes as they
pass through floors, ceilings and roofs.
5. The installer should provide adequate flashing and
sealing boots sized for the vent pipe and combustion
air pipe.
Termination Fittings - Through the Roof
1. The vent and combustion air terminations must include
a factory supplied “bird screen” installed as shown in
Figs. 4, 5 & 6 on page 14.

Direct Vent Installation of Vent/Air Piping
The combustion air inlet of the PRESTIGE is defined
as being part of a direct vent system. It is not con-
sidered as a forced air intake. The required clear-
ance of an adjacent boiler vent to a forced air inlet
does not apply in a multiple installation of PRES-
TIGE boilers.
NOTICE
Direct Vent - Multiple Boiler Installation - Through
the Roof
1. On installations of multiple PRESTIGE boilers, ter-
minate the vent and combustion air piping as
described in this manual.
2. The roof penetration of the vent and combustion air
piping should be such that the combustion air inlet is
a minimum 12” [30.5 cm] from the adjacent vent pipe
of the other boiler for installations in the U.S. as
shown in Fig. 7. For installations in Canada, provide
clearances as required by CAN/CSA B149.1.

Direct Vent - Horizontal - Sidewall
The installation must conform to the requirements of
the authority having jurisdiction or, in the absence
of such requirements, to the ational Fuel Gas
Code, A SI Z223.1/ FPA 54, and/or atural Gas and
Propane Installation Code, CA /CSA B149.1.
For direct vent (sidewall) installations in the
Commonwealth of Massachusetts, the installer must
comply with the additional requirements outlined on
page 37 and 38.
A gas vent extending through a sidewall should not
terminate near an adjacent wall or below any build-
ing extensions such as roof eaves, balconies or
decks. Failure to comply with the required clear-
ances in this manual could result in severe personal
injury, death or substantial property damage.
To reduce the potential of the combustion air inlet
freezing up it is recommended to separate the vent
and air terminations in both a horizontal and vertical
plain as shown in figures 8 through 12 on pages 17
and 18.
If the vent is terminated on a sidewall which is sub-
ject to high winds it is recommended to terminate
the vent using a 45º elbow or tee. A tee provides the
best protection against wind but can expose the
exterior of the house to condensate, while a 45º
elbow provides improved protection from both wind
and condensate.
The information and diagrams outlining the fittings
and method of terminating the vent/combustion air
are directly related to PVC/CPVC vent systems.
