- eating system piping
- Venting
- Gas 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
PRESTIGE Excellence is free of any com-
bustible 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 PRESTIGE Excellence and its con-
trols are protected from dripping or spraying
water during normal operation or service.
The PRESTIGE Excellence 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 sur-
rounding the unit or any lower floors in the
structure.
Boiler Replacement
If the PRESTIGE Excellence is replacing an
existing boiler, the following items should be
checked and corrected prior to installation:
- Boiler piping leaks and corrosion.
- Improper location and sizing of the
expansion tank on the boiler heating
loop.
- If applicable, level and quality of freeze
protection within the boiler system.
Recommended Clearances
The PRESTIGE Excellence is approved for
zero clearance to combustibles, excluding
vent and boiler piping.

Combustion Air Contamination
If the PRESTI E Excellence combus-
tion 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 location. Contaminated com-
bustion air will damage the unit and its
burner system, resulting in possible
severe personal injury, death or substan-
tial property damage.
Do not operate a PRESTI E Excellence
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-
icals / cleaners

Ventilation and Combustion Air
Requirements - Direct Vent
A Direct Vent appliance utilizes uncontaminat-
ed outdoor air (piped directly to the appliance)
for combustion.
For Direct Vent installations, involving only
the PRESTIGE Excellence, in which the mini-
mum service clearances are maintained as list-
ed on page 4, no ventilation openings are
required.
For Direct Vent, zero clearance installations
involving only the PRESTIGE Excellence, the
space / enclosure must provide two openings
for ventilation. The openings must be sized to
provide 1 square inch of free area per 1,000
BTU 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 PRESTIGE
Excellence shares the space with air movers
(exhaust fan, clothes dryers, fireplaces, etc.)
and other combustion equipment (gas or oil)
the space must be provided with adequate air
openings to provide ventilation and combus-
tion air to the equipment. To properly size the
ventilation / combustion air openings, the
installer must comply with the National Fuel
Gas Code NFPA 54, ANSI Z223.1 for installa-
tions in the U.S or CSA B149.1 and B149.2 for
installations 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-
TI E Excellence, excluding the input of
a Direct Vent PRESTI E Excellence
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
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 PRESTIGE
Excellence shares the space with air movers
(exhaust fan, clothes dryers, fireplaces, etc.) and
other combustion equipment (gas or oil) the
space must be provided with adequate air open-
ings to provide ventilation and combustion air to
the equipment. To properly size the ventilation
/ combustion air openings, the installer must
comply with the National Fuel Gas Code NFPA
54, ANSI Z223.1 for installations in the U.S or
CSA B149.1 and B149.2 for installations in
Canada, as referenced in this section of the man-
ual and titled Methods of Accessing
Combustion Air into a Space.
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,

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 Gas Code, ANSI Z223.1/NFPA 54
and/or CAN/CGA 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
Gas Code ANSI Z223.1/NFPA 54 and/or
CAN/CGA B149, Installation codes.
