Section 1 -
GENERAL INFORMATION
WARNING
Brute units must be installed in accordance with the
procedures detailed in this manual, or the Bradford
White warranty will be voided. The installation must
conform to the requirements of the local jurisdiction
having authority, and, in the United States, to the latest
edition of the National Fuel Gas Code, ANSI Z223.1/
NFPA54. In Canada, the installation must conform
to the latest edition of CSA B149.1 Natural Gas and
Propane Gas Installation Code, and/or local codes.
Where required by the authority having jurisdiction,
the installation of Brute boilers must conform to
the Standard for Controls and Safety Devices for
Automatically Fired Boilers, ANSI/ASME CSD-1. Any
modications to the boiler, its gas controls, or wiring
may void the warranty. If eld conditions require
modications, consult the factory representative before
initiating such modications.
1.1 Introduction

Section 2 -
LOCATING THE APPLIANCE
2.1 GeneralInformation
The Brute unit is designed for indoor installations only.
The appliance should be located to provide clearances
on all sides for maintenance and inspection. It should
not be located in an area where leakage of any
connections will result in damage to the area adjacent to
the appliance or to lower oors of the structure.
When such a location is not available, it is
recommended that a suitable drain pan, adequately
drained, be installed under the appliance.
The appliance is design certied by CSA-International
for installation on combustible ooring; in basements;
in closets, utility rooms or alcoves. Brutes must
neverbeinstalledoncarpeting.The location for the
appliance should be chosen with regard to the vent
pipe lengths and external plumbing and on a level
surface. The unit shall be installed such that the gas
ignition system components are protected from water
(dripping, spraying, rain, etc.) during operation and
service (circulator replacement, control replacement,
etc.). When vented vertically, the Brute must be located
as close as practical to the vertical section of the vent.
If the vent terminal and/or combustion air terminal
terminate through a wall, and there is potential for snow
accumulation in the local area, both terminals should
be installed at an appropriate level above grade or the
maximum expected snow line.
The dimensions and requirements that are shown in
Table 1 should be met when choosing the locations for
the appliance.
2.2 LocatingApplianceforCorrectVent
DistancefromOutsideWallor
RoofTermination
The forced draft combustion air blower in the appliance
has sufcient power to vent properly when the
guidelines in Table 2 are followed.
NOTE: When located on the same wall, the Brute
combustion air intake terminal must be installed a
minimum of 12” below the exhaust terminal.Models 399-
850 also require a minimum horizontal distance from
intake to exhaust terminal of 36”.

Installations in the U.S. require exhaust vent pipe that is a combination
of PVC & CPVC complying with ANSI/ASTM D1785 F441 or stainless
steel complying with UL1738. Installations in Canada require exhaust
vent pipe that is certied to ULC S636.
Intake (air) pipe must be PVC or CPVC that complies with ANSI/ASTM
D1785 F441, ABS that complies with ANSI/ASTM D1527 or galvanized
material.
The installer must comply fully with the manufacturer’s installation
instructions, including use of minimum exhaust length CPVC, to main-
tain ANSI Z21.13 safety certication.
Closet and alcove installations do not allow the use of PVC under any
circumstances
To calculate max equivalent length, measure the linear feet of the pipe,
and add 5 feet (1.5m) for each 90°*elbow used.
* For any combination of vent and intake lengths up to 40 equivalent
feet, any even or uneven combination of length is allowed. For overall
lengths greater than 40 equivalent feet, the exhaust may be up to 20
feet greater than the intake length.
*Add 2 1/2 feet (.76 meters) for each 45 elbow used.

12” (300mm) of the top of the enclosure, shall be permitted.
The opening shall directly communicate with the outdoors
or shall communicate through a vertical or horizontal
duct to the outdoors or spaces that directly communicate
with the outdoors and shall have a minimum free area of
1 square inch per 3000 Btu/hr (734 square mm/kW) of the
total input rating of all equipment located in the enclosure.
This opening must not be less than the sum of the areas of
all vent connectors in the conned space.
Other methods of introducing combustion and ventilation air
are acceptable, providing they conform to the requirements
in the applicable codes listed above.
In Canada, consult local building and safety codes or, in
absence of such requirements, follow CAN/CSA B149.
Ducted Combustion Air
The combustion air can be taken through the wall, or
through the roof. When taken from the wall, it must be
taken from out-of-doors by means of the Bradford White
horizontal wall terminal, shown in Table 3a and 3b. See
Table 2 to select the appropriate diameter air pipe. When
taken from the roof, a eld-supplied rain cap or an elbow
arrangement must be used to prevent entry of rain water.
(See Figure10.)
Use ABS, PVC, CPVC or galvanized pipe for the
combustion air intake. (See Table 4.) The pipe should be
sized per Table 2. Route the intake to the boiler as directly
as possible. Seal all joints. Provide adequate hangers.
The unit must not support the weight of the combustion air
intake pipe. Maximum linear pipe length allowed is shown
in Table 2. Subtract 5 allowable linear ft. (1.5m) for every
elbow used.
The connection for the intake air pipe is at the top of the
unit. (See Figure 9.)
In addition to air needed for combustion, air shall also be
supplied for ventilation, including air required for comfort
and proper working conditions for personnel. Refer to the
applicable codes.
3.2 Venting
WARNING
Failure to use polypropylene CPVC or stainless steel
venting for the rst 20” (285-600) / 30” (199 / 210)
of vent material or for any part of the venting that is
installed inside a closet may lead to property damage,
personal injury or death. The proper length of this
material is supplied with boiler. Boilers in the U.S. may
use pipe included with the boiler.
Failure to use the appropriate vent material, installation
techniques, glues/sealants could lead to vent failure
causing property damage, personal injury or death.
All venting must be installed according to this manual
and any other applicable local codes, including but
not limited to, ANSI Z223.1/NFPA 54, CSA B149.1,
CSAB149.2 and ULC-S636. Failure to follow this manual
and applicable codes may lead to property damage,
severe injury, or death.
TheuetemperatureoftheBrutechanges
dramaticallywithchangesinoperatingwater
temperature.Therefore,itisnecessarytoassess
theapplicationoftheboilertodeterminethe

Brute BOILERS AND VOLUME WATER HEATERS
IIb, or a stainless steel venting system that complies with
UL 1738 Standard. (See Table 5.)
The unit’s vent can terminate through the roof, or through
an outside wall.
When using PVC/CPVC for vent material, venting must
be connected to the CPVC section included with Brute
sizes 80-850. The CPVC vent section included with the
Brute may be broken by CPVC ttings if necessary, but
never reduced in total length. See Table 2 to select the
appropriate vent pipe diameter. When using polypropylene,
all vent material must be produced by the same
manufacturer, and have a ULC-S636 rating.
All installations should be done following the vent supplier’s
recommended installation techniques. If manufacturer’s
instructions are not available for the material used, follow
the Bradford White recommendations.
The vent pipe must pitch upward, toward the vent terminal,
not less than 1/4” per foot, so that condensate will run
back to the Brute to drain. Route vent pipe to the heater as
directly as possible. Seal all joints and provide adequate
hangers as required in the venting system manufacturer’s
Installation Instructions. Horizontal portions of the venting
system must be supported to prevent sagging and may not
have any low sections that could trap condensate. The unit
must not support the weight of the vent pipe. Please see
Table 2 for proper diameter vs. length allowed.
IMPORTANT NOTE ABOUT COMMON VENTING: A
single vent that is shared by multiple Brute units MUST
be engineered by a competent venting specialist, and
involves the selection of draft inducing equipment,
hardware and controls to properly balance ue gas
pressures. DonotcommonventBruteunitsunless
theventsystemmeetsthisrequirement.Bruteunits
areneverpermittedtoshareaventwithCategoryI
appliances.
VentingRequirementsUniquetoCanada
Brute boilers and water heaters are Vent Category IV
appliances. Per the requirements of CAN/CSA-B149.1,
only BH vent systems can be connected to these units
and such vent systems, either ULC S636 certied
stainless steel or other ULC S636 certied BH vent (eg.
plastics) must be installed per the vent manufacturer’s
certied installation instructions.
As a result, two items listed in the Unpacking section
(Figure 8) are not included with Brute units for Canada
(underlined):
A exhaustventterminal (not included)
B. air intake terminal
C. temperature/pressure gauge kit
D. circulator pump/wire harness (units with pump)
E. CPVCexhaustpipesection(80-500) (not
incl.)
F. outdoor/system sensor kit
G. ow switch kit (399-850)
H. alternate size vent/terminal screens
J. exhaust vent adapter CPVC/ST ST (750-850)
It is the responsibility of the appropriately licensed
technician installing this Brute unit to use ULC S636
certied vent material consistent with the requirements
as described in the Venting and Combustion Air section.
Class I venting systems are suitable for gas-red
appliances producing ue gas temperature of more than
135°C, but not more than 245°C.
Class II venting systems are suitable for gas-red
appliances producing ue gas temperatures of 135°C or
less.
Class II venting systems are further classied into four
temperature ratings as follows:
A Up to and including 65°C
B Up to and including 90°C
C Up to and including 110°C, and
D Up to and including 135°C
IMPORTANT! It is also the responsibility of the installer
to ensure that a ue gas sampling port is installed in
the vent system. This ue gas sampling port must be
installed near the ue connection of the Brute unit:
within 2 feet of the ue connection. There is no ue
gas sampling port internal to the Brute, so one must
be installed in the vent system external to the Brute
unit. A ue gas sampling port available as a component
of the ULC S636 certied vent system is preferred.
However, if one is not available with the certied vent
system, Bradford White suggests using a tee with the
Figure 12. TestPort-ULC-S636system

Page 12
B RADFORD W HITE
branch connection sized to allow for insertion of a ue
gas analyzer probe. The branch connection must be
resealable with a cap or other by other means to ensure
the vent system remains sealed. (See Figure 11.)
Consideration must be given to the placement and
orientation of the ue gas sampling port to ensure that
condensate is free to ow back into the Brute unit and
not collect anywhere in the vent system - including in the
ue gas sampling port.
An exhaust vent terminal must be installed. If an exhaust
vent terminal is not available with the certied vent
system, Bradford White suggests the use of a coupler
tting from the certied vent system into which the vent
terminal screen, included with the Brute and shown in
the Unpacking section, be installed. Be sure to install
and terminate both vent and combustion air pipes per
the Venting and Combustion Air section of the Brute
instructions.
3.3 LocatingVentandCombustionAir
Terminals
SideWallVentTerminal
The appropriate Bradford White side wall vent terminal
must be used. The terminal must be located in
accordance with ANSI Z223.1/NFPA 54 and applicable
local codes. In Canada, the installation must be in
accordance with CSA B149.1 or .2 and local applicable
codes. Consider the points listed on the following page
when installing the terminal.
1. Figure 12 shows the requirements for mechanical
vent terminal clearances for the U.S. and Canada.
2. Vent terminals for condensing appliances or
appliances with condensing vents are not permitted
to terminate above a public walkway, or over an
area where condensate or vapor could create a
nuisance or hazard.
3. Locate the vent terminal so that vent gases cannot
be drawn into air conditioning system inlets.
4. Locate the vent terminal so that vent gases cannot
enter the building through doors, windows, gravity
inlets or other openings. Whenever possible, avoid
locations under windows or near doors.
5. Locatetheventterminalsothatitcannotbe
blockedbysnow.Theinstallermaydetermine
thataventterminalmustbehigherthanthe
minimumshownincodes,dependingupon
localconditions.
6. Locate the terminal so the vent exhaust does not
settle on building surfaces or other nearby objects.
Vent products may damage surfaces or objects.
7. If the boiler or water heater uses ducted combustion
air from an intake terminal located on the same
wall.
If the vent termination is located in an area exposed to
high winds, an optional PVC tee (the same diameter as
the vent pipe) may be used. The tee’d vent termination
offers greater protection from wind related operating
issues.
SideWallCombustionAirTerminal
The Bradford White side wall combustion air terminal, or
concentric terminal must be used when the heater takes
air from a side wall. (See Table 3.) Contact Bradford
White for AL29-4C termination ttings. Consider the
following when installing the terminal. (See Figures 13-
15.)
1. Do not locate the air inlet terminal near a source
of corrosive chemical fumes (e.g., cleaning uid,
chlorine compounds, etc.)
2. Locate the terminal so that it will not be subject to
damage by accident or vandalism. It must be at
least 7 feet (2.1m) above a public walkway.
3. Locate the combustion air terminal so that it cannot
be blocked by snow. The National Fuel Gas Code
requires that it be at least 12 inches (30cm) above
grade, but the installer may determine it should be
higher, depending upon local conditions.
4. If the Brute is side-wall vented to the same wall,
locate the vent terminal at least 1 foot (0.3m) above
the combustion air terminal.
5. Forconcentricvent,followinstructions
includedwithventkit.
6. Multiple vent kits should be installed such that the
horizontal distance between the outlet group and
the inlet group is 36” (90cm). (Figure 14.)
7. The vent outlet for models 199-285 must be no
lower than the center of the air inlet, and must be
at least 12” (30cm) away from the air inlet. Vent
outlets for models 399-850 must be at least 12”
above the top of the air inlet, and must be at least
36” (90cm) horizontally from the air inlet. (Figure
14.)
VerticalVentTerminal
When the unit is vented through the roof, the vent must
extend at least 3 feet (0.9m) above the point at which it
penetrates the roof. It must extend at least 2 feet (0.6m)
higher than any portion of a building within a horizontal
distance of 10 feet (3.0m), and high enough above
the roof line to prevent blockage from snow. The vent
terminal included with the Brute can be used in both
vertical and horizontal applications. When the combustion
air is taken from the roof, the combustion air must
terminate at least 12” (30cm) below the vent terminal. (See
Figure 10.)
VerticalCombustionAirTerminal
When combustion air is taken from the roof, a eld-
supplied rain cap or an elbow arrangement must be used
to prevent entry of rain water. (Figure 10.) The opening on

Section 4 -
GAS SUPPLY AND PIPING
Gas piping should be supported by suitable hangers or
oor stands, not the appliance.
Review the following instructions before proceeding with
the installation.
1. Verify that the appliance is tted for the proper
type of gas by checking the rating plate. Brute will
function properly without the use of high altitude
modication at elevations up to 10,000 feet (3050
m).
2. The maximum inlet gas pressure must not
exceed 13” W.C. (3.2kPa). The minimum inlet gas
pressure is 4” W.C. (1.0kPa).
3. Refer to Tables 6a, 6b, 6c and 6d to size the
piping.
4. Run gas supply line in accordance with all
applicable codes.
5. Locate and install manual shutoff valves in
accordance with state and local requirements.
6. A sediment trap must be provided upstream of the
gas controls.
7. All threaded joints should be coated with piping
compound resistant to action of liqueed petroleum
gas.
8. The appliance and its individual shutoff valve
must be disconnected from the gas supply piping
during any pressure testing of that system at test
pressures in excess of 1/2 PSIG (3.45kPa).
9. The unit must be isolated from the gas supply
system by closing its individual manual shutoff
valve during any pressure testing of the gas supply
piping system at test pressures equal to or less
than 1/2 PSIG (3.45kPa).
10. The appliance and its gas connection must be leak
tested before placing it in operation.
11. Purge all air from gas lines.
WARNING:
Open ame can cause gas to ignite and result in
property damage, severe injury, or loss of life.
NOTE: The Brute appliance and all other gas appliances
sharing the gas supply line must be ring at maximum
capacity to properly measure the inlet supply pressure.
The pressure can be measured at the supply pressure
port on the gas valve. Low gas pressure could be an
indication of an undersized gas meter, undersized gas
supply lines and/or an obstructed gas supply line. Some
Brute units are equipped with low and high gas pressure
switches that are integrally vent limited. These types of
devices do not require venting to atmosphere.
3.4 Common Vent Test
NOTE: This section does not describe a method for
common venting Brute units. It describes what must be
done when a unit is removed from a common vent system.
Brute units require special vent systems and fans for
common vent. Contact the factory if you have questions
about common venting Brute units.
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 appliances remaining connected
to it.
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.
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 it 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 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 the thermostat so
the 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 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, replace dampers and
any other gas burning appliance to their previous
conditions of use.
7. Any improper operation of the common venting system
should be corrected so that the installation conforms
to the National Fuel Gas Code, ANSI Z223.1/NFPA 54
and/or CSA B149.1, Installation Codes. When resizing
any portion of the common venting system, the com-
mon venting system should be resized to approach
the minimum size as determined using the appropriate
tables and guidelines in the National Fuel Gas Code,
ANSI Z223.1 NFPA 54 and/or CSA B149.1, Installation
Codes.

TO SIZE PIPING:
Measure linear distance from meter outlet to last
boiler. Add total input of all boilers and divide
by 1000 to obtain cu ft / hr required. Add total
equivalent length of ttings used according to
Table 6B. Align total length (pipe and ttings) on
left side column of Table 6C with highest cubic
feet of gas required.
Notes:
Consult and conrm with Applicable Fuel Gas
Code before beginning work. Verify gas inlet
pressure is between 4 and 13 in W.C. before
starting boiler.
