Horizontal Vent/Ducted Air Distance From
Outside Wall

The forced draft combustion air blower in the

appliance has sucient power to pull air and vent

properly when the guidelines for horizontal air and
vent are followed (see Table 1).

NOTE: On some models, the vent collar size is
larger than the size of the vent pipe that can be
used. Vent collar size and horizontal pipe diameters
can be found in Table 1 The larger vent collar size is
to accommodate Category I (vertical) vent systems.

NOTE: When located on the same wall, the Brute

a chimney or outside wall. 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 such that blockage of
the terminal from accumulated debris or precipitation

is prevented.

Deluxe combustion air intake terminal must be
installed a minimum of 12" (30cm) below the
exhaust vent terminal and separated by a minimum
of 36 inches (91cm) horizontally.

The air intake terminal must be installed high
enough to avoid blockage from snow, leaves and other

debris.

The dimensions and requirements that are shown

in Table 2 should be met when choosing the locations

for the appliance.

1.F Locating Pump-Mounted Water
Heater with Respect to Storage Tank(s)

For best results, a pump-mounted Brute Deluxe
water heater should be located within 15 feet (4.6m)
of the storage tank(s). The pump is sized for 30 feet
(9.1m) of piping.

If the appliance must be installed with longer
piping runs, then larger diameter pipe or tubing may be

acceptable. Consult the factory for assistance.

WARNING

For indoor installations, as an additional
measure of safety, National Combustion Co.
strongly recommends installation of suitable
Carbon Monoxide detectors in the vicinity of this
appliance and in any adjacent occupied spaces.

AVERTISSEMENT

Pour des installations intérieures, National
Combustion Co. recommande fortement, comme
mesure de sécurité supplémentaire, l’installation
de détecteurs de monoxyde de carbone adaptés
dans le voisinage de l’appareil et dans chacune
des pièces habitées adjacentes.

2.A Combustion Air

Brute Deluxe boilers and water heaters must
have provisions for combustion and ventilation air in
accordance with the applicable sections addressing
requirements for air for combustion and ventilation of

the National Fuel Gas Code, ANSI Z223.1. In Canada,
the applicable sections of the Natural Gas and Propane
Installation Code (CSA B149.1) must be followed. In

all cases any and all applicable local installation codes

must also be followed.

A Brute Deluxe appliance may receive
combustion air from the space in which it is installed,

or it can be ducted directly to the unit from the outside.
Proper ventilation air must be provided in either case.

2.A.1 Combustion Air From Room

In the United States, the most common
requirements specify that the space shall communicate
with the outdoors in accordance with method 1 or 2,

which follow. Where ducts are used, they shall be of

the same cross-sectional area as the free area of the

openings to which they connect.

Method 1: Two permanent openings, one

commencing within 12 inches (30 cm) of the top
and one commencing within 12 inches (30 cm) of
the bottom, of the enclosure shall be provided. The

openings shall communicate directly, or by ducts,
with the outdoors or spaces that freely communicate

with the outdoors. When directly communicating

with the outdoors, or when communicating to the
outdoors through vertical ducts, each opening shall
have a minimum free area of 1 square inch per 4000

Btu/hr (5.5 square cm/kW) of total input rating of all
equipment in the enclosure. When communicating to the

outdoors through horizontal ducts, each opening shall
have a minimum free area of not less than 1 square inch
per 2000 Btu/hr (11 square cm/kW) of total input rating

of all equipment in the enclosure. Table 1 shows data for
this sizing method, for each Brute Deluxe model.

Method 2: One permanent opening, commencing

within 12 inches (30 cm) 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 (7 square cm/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 CSA

B149.1, the Natural Gas and Propane Installation Code.

Page 9

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 (see Table 1).

When taken from the roof, a eld-supplied rain cap or

an elbow arrangement must be used to prevent entry of
rain water (see Figure 3).

Use single-wall galvanized pipe for the

combustion air intake (see Table 1 for appropriate

size). Route the intake to the heater as directly as
possible. Seal all joints with tape. Provide adequate
hangers. The unit must not support the weight of the
combustion air intake pipe. Maximum linear pipe
length allowed is 50 feet (15.2m). Three elbows have
been calculated into the 50-foot (15.2m) linear run.
Subtract 10 allowable linear feet (3.0m) for every

additional elbow used (see Table 1). When fewer than

3 elbows are used, the maximum linear pipe length
allowed is still 50 feet (15.2m).

Term Description
Pipe Single-wall galvanized steel pipe, 24 gauge

minimum (either insulated or non-insulated)

Joint Sealing Permanent duct tape or aluminum tape

Table 3. Required Combustion Air Piping

Material.

The connection for the intake air pipe is on the

lter box. The Brute Deluxe appliances may have

venting and combustion air ducting attached to the top

or the back. They are shipped with the connections
at the top. For attaching either or both pipes to the
back, the mounting anges are reversible by removing
the mounting screws and orienting the anges in the
desired position. Replace the screws after positioning
anges. Run a bead of silicone around the collar and
slide the pipe over the collar. Secure with sheet metal
screws.

In addition to air needed for combustion, air
shall also be supplied for ventilation, including all air
required for comfort and proper working conditions

for personnel. The Brute Deluxe loses less than 1

percent of its input rating to the room, but other heat

sources may be present.

Category I vent system, and includes rules and tables

to size these vent systems. If the Brute Deluxe’s

vertical vent system does not satisfy the criteria for
Category I venting, it must be vented as a Category III

system.

All Brute Deluxe vent systems which discharge

horizontally (without the use of a power venter) are

considered Category III vent systems.

2.B.2 Category I Vent

When vented as a Category I appliance, the

vent system must conform to the National Fuel Gas
Code (ANSI Z223.1-Latest Edition) in the U.S., or in
Canada, to the Natural Gas and Propane Installation
Code (CSA B149.1 latest edition). The vent system
must be sized and installed for a Category I Fan­Assisted Appliance.

If chimney height is greater than 25 feet, or

if multiple units are vented into the same vertical
vent, a barometric damper must be installed on each

appliance, such that the ue draft does not exceed
(negative) 0.1 in. w.c.

If using a power venter for any type of Category

I venting, the draft should be set between (negative)

0.01 and 0.05 in. w.c.

2.B.3 Common Venting Systems

Brute Deluxe units are Category I fan-assisted

when vented vertically and adhering to all applicable

codes. Brute Deluxe units are not allowed to be

vented into a common horizontal vent system, unless
a properly sized vent fan is used, and the common
vent system is properly designed by the vent fan

manufacturer or a qualied engineer. When common

venting Brute Deluxe fan-assisted unit with other
appliances through one shared vertical duct called a

“common vent”, special care must be taken by the
installer to ensure safe operation. In the event that

the common vent is blocked, it is possible, especially
for fan-assisted devices, to vent backwards through
non-operating appliances sharing the vent, allowing

combustion products to inltrate occupied spaces.

If the appliances are allowed to operate in this
condition, serious injury or death may occur.

2.B Venting

2.B.1 Vent Categories

Depending upon desired Brute Deluxe venting,
it may be considered a Category I or a Category III

appliance. In general, a vertical vent system will be
a Category I system. However, in rare instances, a

Brute Deluxe’s vertical vent system may be considered

Category III. In the U.S., the National Fuel Gas Code
(ANSI Z223.1), or in Canada the Natural Gas and
Propane Installation Code (CSA B149.1), denes a

WARNING

Operation of appliances with a blocked common
vent may lead to serious injury or death. Safety
devices must be implemented to prevent blocked
common vent operation. If safe operation of all
appliances connected to a common vent cannot
be assured, including prevention of spillage of
flue gasses into living spaces, common venting
should not be applied, and appliances should
each be vented separately.

Le fonctionnement d’appareils connectés à
un évent commun bouché peut provoquer de
sérieuses blessures corporelles ou la mort.
Des dispositifs de sécurité doivent être mis en
place pour empêcher que les appareils soient
utilisés avec un évent commun bouché. Si un
fonctionnement sécuritaire de tous les appareils
reliés à un évent commun et si la prévention des
dégagements accidentels de gaz de combustion
dans des zones habitées ne peuvent pas être
assurés, un évent commun ne doit pas être mis
en place et les appareils doivent être munis
d’évents individuels séparés.

It is for this reason that, in addition to

following proper vent sizing, construction and safety

requirements from the National Fuel Gas Code,
ANSI Z223.1 or in Canada, from the Natural Gas
and Propane Installation Code (CSA B149.1) as

well as all applicable local codes, it is required that
installers provide some means to prevent operation

with a blocked common vent. It is suggested that a

blocked vent safety system be employed such that if
the switch from one appliance trips due to excessive
stack spill or back pressure indicating a blocked vent
condition, that all appliances attached to the vent be

locked out and prevented from operating. Note that

the Brute Deluxe is equipped with a blocked vent

safety (pressure) switch, as shipped. However, this

safety switch has only been designed and tested to

be eective in installations where the Brute Deluxe
is vented separately and NOT common vented with
other appliances. As an additional precaution, it is

recommended that a Carbon Monoxide (CO) alarm be
installed in all enclosed spaces containing combustion

appliances. If assistance is required in determining

how a blocked vent safety system should be connected
to a Bradford White product, please call Applications

Engineering at the Rochester phone number on the
back cover of this manual.

Refer to the installation and operating

instructions on all appliances to be common vented
for instructions, warnings, restrictions and safety

requirements. If safe operation of all appliances

connected to a common vent cannot be assured,

including prevention of spillage of ue gases into

living spaces, common venting should not be applied,

and appliances should each be vented separately.

2.B.4 Category III Vent

When the Brute Deluxe is vented with horizontal
discharge, it must be installed per this installation
manual and the venting system manufacturer’s

installation instructions. The vent system must be

sealed stainless steel, per Table 4.

Term Description

Pipe Must comply with UL Standard 1738 such

as Type AL29-4C Stainless Steel
(either insulated or non-insulated).

Joint

Sealing

Table 4. Required Horizontal Venting Material.

Follow vent manufacturer's instructions.

Route the 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. Horizontal runs must slope downwards not less

than ¼ inch per foot (2 cm/m) from the unit to the vent

terminal.

L’appareil ne doit pas supporter le poids de la
gaine d’évent. Les parties horizontales doivent être
installées avec une pente de 2 cm/m (1/4 inch par pied)
descendant de l’appareil vers la sortie de l’évent.

Reference Table 1 for the size of the Category
III vent system. Up to three elbows can be used with
50 linear feet (15.2m) of pipe. Subtract 10 allowable
linear feet (3.0m) for every additional elbow used.

2.C Locating Vent & Combustion Air
Terminals

2.C.1 Side Wall Vent Terminal

The appropriate Bradford White side wall vent
terminal must be used, and is listed in the installation

and operation manual. The terminal provides a means

of installing the vent piping through the building wall,

and 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
and local applicable codes. Consider the following

when installing the terminal:

1. Figure 4 shows the requirements for mechanical
vent terminal clearances for the U.S. and Canada.

2. Locate the vent terminal so that vent gases cannot
be drawn into air conditioning system inlets.

3. Locate the vent terminal so that vent gases cannot

enter the building through doors, windows, gravity

inlets or other openings. Whenever possible,

locations under windows or near doors should be

avoided.

4. 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.

5. Locate the terminal so the vent exhaust does not
settle on building surfaces or other nearby objects.
Vent products may damage such surfaces or
objects.

2.C.2 Side Wall
Combustion Air Terminal

The Bradford White side wall combustion air terminal

(listed in Table 1) must be used when the unit
takes its combustion air through a duct from a side

wall. Consider the following when installing the

terminal:

1. Do not locate the air inlet terminal near a source
of corrosive chemical fumes (e.g., cleaning uid,
chlorinated compounds, etc.)

2. Locate the terminal so that it will not be subject to
damage by accident or vandalism.

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 (30 cm)

above grade, but the installer may determine it

should be higher, depending upon local conditions.

4. If the Brute Deluxe is side-wall vented to the same
wall, locate the vent terminal at least 3 feet (0.9m)

horizontally from the combustion air terminal,

and locate the vent terminal at least 1 foot (0.3m)

above the combustion air terminal (see Figure 4).

2.C.3 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. When the combustion air is taken from the roof,
the combustion air must terminate at least 12" (30cm)

below the vent terminal (see Figure 3).

2.C.4 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 (see Figure 3).
The opening on the end of the terminal must be at least

12" (30cm) above the point at which it penetrates the

roof, and high enough above the roof line to prevent

blockage from snow. When the vent terminates on the

roof, the combustion air must terminate at least 12"

(30cm) below the vent terminal.

2.D Common Vent Test — Boilers

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

non 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 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

cigarette, cigar or pipe.

6. After it has been determined that each appliance

remaining connected to the common venting

Page 14

Bradford White Corp

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 with the National Fuel Gas Code,
ANSI Z223.1/NFPA 54 and/or CSA B149.1,
Natural Gas and Propane Installation Codes.

When resizing any portion of the common
venting system, the common venting system
should be resized to approach the minimum size
as determined using the appropriate tables in

Appendix F in the National Fuel Gas Code, ANSI
Z223.1/NFPA 54 and/or CSA B149.1, Natural
Gas and Propane Installation Codes.

2.D Véricationdeséventscommuns—
Chaudières

Lorsqu’une chaudière existante est déconnectée

du réseau d’évents commun, ce réseau d’évents
commun devient probablement trop grand pour
les appareils qui lui restent connectés. Lorsqu’une
chaudière existante est retirée, les étapes suivantes
doivent être accomplies pour chaque appareil qui
reste connecté au réseau d’évents commun utilisé,
alors que les autres appareils qui sont encore
connectés au réseau commun d’évents ne sont pas en
fonctionnement.:

1. Sceller toutes les ouvertures non utilisées du
système d'évacuation.

2. Inspecter de façon visuelle le système
d'évacuation pour déterminer la grosseur et
l'inclinaison horizontale qui conviennent et
s'assurer que le système est exempt d'obstruction,
d'étranglement, de fuite, de corrosion et autres
défaillances qui pourraient présenter des risques.

3. Dans la mesure du possible, fermer toutes les
portes et les fenêtres du bâtiment et toutes les
portes entre l'espace où les appareils toujours
raccordés au système d'évacuation sont installés
et les autres espaces du bâtiment. Mettre en
marche les sécheuses, tous les appareils non
raccordés au système d'évacuation common
et tous les ventilateurs d'extraction comme
les hottes de cuisinière et les ventilateurs des
salles de bain. S'assurer que ces ventilateurs
fonctionnent à la vitesse maximale. Ne pas faire
fonctionner les ventilateurs d'été. Fermer les
registres des cheminées.

4. Mettre l'appareil inspecté en marche. Suivre les
instructions d'allumage. Réegler le thermostat de
façon continue.

5. Faire fonctionner le brûleur principal pendant
5 min ensuite, déterminer si le coupe-tirage
déborde à l'ouverture de décharge. Utiliser la

amme d'une allumette ou d'une chandelle ou la

fumée d'une cigarette, d'un cigare ou d'une pipe.

6. Une fois qu'il a été déterminé, selon la méthode
indiquée ci-dessus, que chaque appareil
raccordé au système d'évacuation est mis à l'air
libre de façon adéquate. Remettre les portes
et les fenêtres, les ventilateurs, les registres de
cheminées et les appareils au gaz à leur position
originale.

7. Tout mauvais fonctionnement du système
d'évacuation commun devrait être corrigé
de façon que l'installation soit conforme au
National Fuel Gas Code, ANSI Z223.1/NFPA
54 et (ou) aux codes d'installation CSA-B149.1.
Si la grosseur d'une section du système devrait

être modié, le système devrait être modié pour

respecter les valeurs minimales des tableaux
pertinents de l'appendice F du National Fuel Gas
Code, ANSI Z223.1/NFPA 54 et (ou) les codes
d'installation CSA-B149.1

2.E Vent Terminals for Outdoor Units

For outdoor applications, the vent and

combustion air openings must be covered with proper
terminals to prevent rain, snow and other objects from

falling into the Brute Deluxe.

Outdoor Vent / Air kit part numbers are shown in

Table 6. These kits contain parts for both combustion

air inlet and exhaust vent connections. An angled sheet

metal assembly with louvers replaces the sheet metal

assembly with the air collar. An adapter, a 12" length

of pipe, and a rain cap are included for the exhaust

vent opening.

If local codes allow, Bradford White kits are

not required for outdoor units. The installer may use

12" of appropriately sized galvanized single wall or

b-type vent pipe and a rain cap for the exhaust vent. In

addition, an appropriately sized galvanized 90° elbow,
positioned with the opening facing down, may be used

on the combustion air inlet.

SECTION 3 Gas Supply and Piping

Page 15

3.A Gas Supply and Piping

Gas piping should be supported by suitable

hangers or oor stands, not by the appliance.

The Brute Deluxe’s gas train allows the user to

pipe the gas from either the right side or the left side

of the unit. As shipped, the right side of the gas train is
capped o, and there is a manual valve on the left side.

If desired, the manual valve on the left side of the gas
train may be moved to the right side, and the cap on

the right side may be moved to the left.

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

Deluxe appliances are equipped to operate at

elevations up to 10,000 feet (3050m). Brute

Deluxe appliances may be adjusted to operate

properly at altitudes above 2500 feet (see Section

6.5.2) and the input will be reduced if the heating
value of the gas supply is below sea level values.

2. The maximum inlet gas pressure must not
exceed 13" w.c. (3.2kPa). The minimum inlet gas
pressure is 5 in. w.c. (1.2 kPa).

3. Refer to Table 6, to size supply.

4. Run gas supply line in accordance with all
applicable codes.

5. Locate and install manual shuto 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 shuto valve

must be disconnected from the gas supply piping
during any pressure testing of that system at test

pressures in excess of 0.5 psig (3.45 kpa).

9. The unit must be isolated from the gas supply
system by closing its individual manual shuto

valve during any pressure testing of the gas
supply piping system at test pressures equal to or

less than 0.5 psig (3.45 kpa).

10. The appliance and its gas connection must be
leak tested before placing it in operation.

11. Purge all air from gas lines.

WARNING

Do not use open flame to check for leaks.
An open flame could lead to explosion, which
could result in property damage, serious injury
or death.

AVERTISSEMENT

Ne recherchez pas les fuites avec une flamme
nue. Une flamme nue peut provoquer une
explosion qui peut causer des dommages
matériels, de sérieuses blessures corporelles
ou la mort.

NOTE: The Brute Deluxe appliance and all other
gas appliances sharing the gas supply line must
be firing 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.

SECTION 4 Water Connections —

4.A Brute Deluxe Boiler

Bradford White Corp

4.A.1 Heating System Piping:
Hot Supply Connections — Boiler

NOTE: This appliance must be installed in a closed

pressure system with a minimum of 12 psig (82.7
kPa) static pressure at the boiler.

Hot water piping should be supported by suitable

hangers or oor stands. Do not support piping with
this appliance. Due to expansion and contraction of

copper pipe, consideration should be given to the type

of hangers used. Rigid hangers may transmit noise

through the system resulting from the piping sliding in

the hangers. It is recommended that padding be used
when rigid hangers are installed. Maintain 1" clearance
to combustibles for hot water pipes.

Pipe the discharge of the relief valve (full size)

to a drain or in a manner to prevent injury in the event

of pressure relief. Install an air purger, an air vent,

a diaphragm-type expansion tank, and a hydronic

ow check in the system supply loop. Minimum ll
pressure must be 12 psig (82.7 kPa). Install shuto
valves where required by code.

Suggested piping diagrams are shown as Figure 5,

Figure 6, Figure 7, and Figure 8, and Figure 9. These

diagrams are meant only as a guide. Components
required by local codes must be properly installed.

4.A.2 Cold Water Make-Up — Boiler

1. Connect the cold water supply to the inlet
connection of an automatic ll valve.

2. Install a suitable back ow preventer between the
automatic ll valve and the cold water supply.

3. Install shut o valves where required.

NOTE: The boiler, when used in connection with a
refrigeration system, must be installed so the chilled
medium is piped in parallel with the boiler with
appropriate valves to prevent the chilled medium
from entering the boiler.

The boiler piping system of a hot water heating

boiler connected to heating coils located in air
handling appliances where they may be exposed to

refrigerated air circulation must be equipped with ow

control valves or other automatic means to prevent
gravity circulation of the boiler water during the

cooling cycle.

A boiler installed above radiation level, or as

required by the authority having jurisdiction, must be

provided with a low water cuto device either as a part
of the boiler or at the time of boiler installation.

4.A.3 Water Flow Requirements — Boiler

A hydronic heating (closed loop) application

recirculates the same uid in the piping system. As a

result, no new minerals or oxygen are introduced into

the system. To ensure a proper operating temperature
leading to long boiler life, a ow rate has been
established based on the uid temperature rise for this
specic size boiler.

Pump-mounted boilers can be ordered for use in

primary secondary piping systems. The pumps used
are sized for the head loss through the heater, plus 30
feet (9.1 m) of full-sized piping (same size as boiler
outlet) and a normal number of ttings.

Table 8 species water ow rates for boilers,

which will enable the user to size a pump. The head

loss shown is for the heater only, and the user will
need to add the head loss of the system piping to

properly size the pump.

The minimum inlet water temperature for the

Brute Deluxe is 120°F (49°C) to avoid condensing on
the copper coils.

4.A.4 Freeze Protection — Boiler

Boiler installations are not recommended in

areas where the danger of freezing exists unless proper

precautions are made for freeze protection. A non

toxic, heating system, anti-freeze may be added to
the hydronic system provided that the concentration

does not exceed 50% and the anti freeze contains an
anti foamant. When a 50/50 mixture is used, increase
the water ow requirements by 15%, and increase the
head loss requirements by 20%.

Power outage, interruption of gas supply, failure

of system components, activation of safety devices,

etc., may prevent a boiler from ring. Any time a
boiler is subjected to freezing conditions, and the

boiler is not able to re, and/or the water is not able

to circulate, there is a risk of freezing in the boiler
or in the pipes in the system. When water freezes,

it expands. This can result in bursting of pipes in the

system, or damage to the boiler, which could result in

leaking or ooding conditions.

IMPORTANT NOTES: Different glycol products
may provide varying degrees of protection. Glycol
products must be maintained properly in a heating
system, or they may become ineffective. Consult
the glycol specifications, or the glycol manufacturer,
for information about specific products,
maintenance of solutions, and set up according to
your particular conditions. Never use ethylene glycol
(automotive antifreeze).

pump draws water from the storage tank and pumps

the water through the heater and back into the tank.

Pump-mounted units have a circulating pump built

into the water heater. The pumps used are sized for
the head loss through the heater, plus 30 feet (9.1 m)

of full-sized piping (same size as boiler outlet) and

a normal number of ttings. Pumps used on pump-

mounted unit are sized for soft/normal or hard water,
so make sure a pump-mounted unit matches the water

quality of the installation.

Pipe the outlet from the heater’s relief valve
such that any discharge from the relief valve will be
conducted to a suitable place for disposal when relief

occurs. Do not reduce line size or install any valves in
this line. The line must be installed to allow complete
drainage of both the valve and the line.

4.B.4 Combined Water Heating (potable) and
Space Heating — Water Heater

NOTE: These systems are not allowed in the

Commonwealth of Massachusetts.

4.B.2 Hot Water Supply Piping —Water
Heater

Follow the tank manufacturer’s guidelines for

completion of the hot water system connections.

NOTE: A listed temperature and pressure relief
valve listed as complying with the Standard
for Relief Valves and Automatic Gas Shutoff
Devices for Hot Water Supply Systems (ANSI
Z21.22/CSA 4.4), of suitable discharge capacity
must be installed in the separate storage tank
system.

If the Brute Deluxe water heater is installed in

a closed water supply system, such as one having a

backow preventer in the cold water supply line, the

relief valve may discharge periodically, due to thermal

expansion. Means (such as a properly-sized expansion
tank) shall be provided to control thermal expansion.

Contact the water supplier or local plumbing inspector

on how to control this situation.

4.B.3 Water Flow Requirements —
Water Heater

In a water heating application (an open system),

new water is constantly being introduced. With the

new water comes a fresh supply of minerals that can

be deposited on the unit’s heat exchanger. This is
commonly known as scaling. The amount of minerals
will depend upon the hardness of the water. Water can

also be aggressive, and can erode metals, including

copper, if the water is moved too quickly. The water
ow requirements for the Brute Deluxe water heater
are based upon the hardness of the water. The water
ow is kept high enough to prevent scaling, but low
enough to prevent tube erosion. For extremely soft or
hard water, cupro-nickel tubes are available. Contact a

Bradford White representative if you have questions or

concerns about water quality.

Pump-mounted water heaters can be ordered with

standard pumps for soft or normal water. The pumps

used are sized for the head loss through the heater, plus

30 feet (9.1m) of full-sized piping (same size as heater
outlet) and a normal number of ttings. For hard water
conditions (more than 17 grains per gallon), use a
non-pump-mounted heater with a properly-sized eld­installed pump.

Table 8 species water ow rates for water

heaters, which will enable the user to size a pump. The

head loss shown is for the heater only, and the user
will need to add the head loss of the piping system to

properly size the pump.

Piping and components connected to this water

heater for the space heating application shall be

suitable for use with potable water.

Toxic chemicals, such as used for boiler

treatment, shall not be introduced into the potable

water used for space heating.

This water heater when used to supply potable
water shall not be connected to any heating system
or component(s) previously used with a non-potable

water heating appliance.

When the system requires water for heating at
temperatures higher than required for other uses,
an anti-scald mixing or tempering valve shall be
installed to temper the water for those uses in order
to reduce scald hazard potential.

4.B.5 Freeze Protection — Water Heater

Although Brute Deluxe water heaters are design-

certied for outdoor installations, such installations

are not recommended in areas subject to freezing

temperatures, unless proper precautions are taken.

Power outage, interruption of gas supply, failure
of system components, activation of safety devices,

etc., may prevent a heater from ring. Any time a
heater is subjected to freezing conditions, and the

heater is not able to re, and/or the water is not

able to circulate, there is a risk of freezing in the
heater or in the pipes in the system. When water

freezes, it expands. This can result in bursting of pipes

in the system, or damage to the heater, which could

result in leaking or ooding conditions.

Contact the local factory representative or

Bradford White for additional information.

control damage could occur.

5.C Low Water Cut-O󰀨

When this boiler is installed above radiation

level, it is required that a Low Water Cut-O (LWCO)

be installed unless this requirement is superceded by

Jurisdictional requirements. Specic instructions for the

installation are the following:

Locate the Field Interlocks on the wiring diagram.
These are the electrical connection points for the LWCO.
Follow LWCO Manufacturer’s Wiring Instructions.

Mechanically, install the LWCO device in a tee
tting in the supply piping above the highest point of the
boiler (unless the boiler has an existing tting for that
purpose). Follow LWCO Manufacturer’s Instructions for
minimum pipe sizing.

Note: This boiler is a water tube boiler that requires
water ow through the heat exchanger for proper
operation. It does not have an operating water level and
must be full at all times. In accordance with ANSI/ASME
CSD-1 Section CW-210 and The National Fuel Gas Code
ANSI Z223.1/NFPA 54 Section 10.3.5 a water tube boiler
shall have a water ow proving device in lieu of a Low

SECTION 6 Operating Instructions

6.A Filling the Boiler System

1. Ensure the system is fully connected. Close all
bleeding devices and open make-up water valve.
Allow system to ll slowly.

2. If make-up water pump is employed, adjust

pressure switch on pumping system to provide

a minimum of 12 psi (81.8 kPa) at the highest
point in the heating loop.

3. If a water pressure regulator is provided on the

make-up water line, adjust the pressure regulator

to provide at least 12 psi (81.8 kPa) at the highest
point in the heating loop.

4. Open bleeding devices on all radiation units

at the high points in the piping throughout
the system, unless automatic air bleeders are

provided at such points.

5. Run system circulating pump for a minimum of
30 minutes with the boiler shut o.

6. Open all strainers in the circulating system,
check ow switch operation, and check for
debris. If debris is present, clean out to ensure
proper circulation.

7. Recheck all air bleeders as described in Step 4.

8. Check liquid level in expansion tank. With the

system full of water and under normal operating
pressure, the level of water in the expansion tank
should not exceed ¼ of the total, with the balance

lled with air.

9. Start up boiler according to the procedure in this
manual. Operate the entire system, including the
pump, boiler, and radiation units for one (1) hour.

10. Recheck the water level in the expansion tank. If

the water level exceeds ¼ of the volume of the
expansion tank, open the tank drain, and drain to

that level.

11. Shut down the entire system and vent all

radiation units and high points in the system

piping, as described in Step 4.

12. Close make-up water valve and check strainer in

pressure reducing valve for sediment or debris

from the make-up water line. Reopen make-up
water valve.

13. Check gauge for correct water pressure and also
check water level in the system. If the height

indicated above the boiler insures that water is at
the highest point in the circulating loop, then the

system is ready for operation.

14. Refer to local codes and the make-up water

valve manufacturer’s instructions as to whether
the make-up water valve should be left open or

closed.

15. After placing the unit in operation, the ignition
system safety shuto device must be tested.
First, shut o the manual gas valve, and call
the unit for heat. After the pre-purge and ignitor

heat-up time, the main gas terminals will be

energized, attempting to light, for seven (7)
seconds, and then will de-energize. The unit will

attempt to light two more times, and then will go

into lockout mode. Second, turn the power o

and then on again, open the manual gas valve

and allow the unit to light. While the unit is

operating, close the manual gas valve and ensure

that power to the main gas valve has been cut.

16. Within three (3) days of start-up, recheck all air

bleeders and the expansion tank as described in

Steps 4 and 8 above.

Important: The installer is responsible for identifying
to the owner/operator the location of all emergency
shutoff devices.

WARNING

Do not use this appliance if any part has been under
water. Immediately call a qualified service technician
to inspect the appliance and to replace any part of
the control system and any gas control that may have
been under water.

Inactive (O) /Active 3 min. (On). In the On position
the pump will continue to run for 3 min after the last
call has been satised. When the dip switch is O
there is no post purge of the pump, the pump turns o
immediately after the last call is removed. Bradford
White strongly recommends using a pump post purge.
During WWSD and a call for HEAT is present the
pump will remain o.

Pump Exercising The control exercises the

boiler pump every 3 days of inactivity. While the
control is exercising the pump all LEDs will turn o
and the power LED will ash for 10 seconds.

Staging (where applicable – factory setting):
Dip switch #1 is used to select the number of stages:

2-Stage (O) / Single Stage (On).

For 2-stage operation, the rst stage is cycled

on Proportional error and the second stage is cycled

based on PI according to a xed algorithm. No user
adjustment is necessary.

Note: All stages are turned o when the water

outlet temperature reaches the Maximum setting
that is elected via dip switch #4, Boiler Maximum

210°F (O) / 190°F (On). Commercial boilers have
dip switch #2 set for ‘O’ to allow setpoint control.
Utilize dial to set desired outlet temp.

NOTE:

This boiler is equipped with a feature that saves
energy by reducing the boiler water temperature as
the heating load decreases. This feature is equipped
with an override which is provided primarily to permit
the use of an external energy management system
that serves the same function. THIS OVERRIDE
MUST NOT BE USED UNLESS AT LEAST ONE OF
THE FOLLOWING CONDITIONS IS TRUE:

• An external energy management system is
installed that reduces the boiler water temperature
as the heating load decreases.

• This boiler is not used for any space heating.

• This boiler is part of a modular or multiple boiler
system having a total input of 300,000 BTU/hr or
greater.

• This boiler equipped with a tankless coil.

Auto Boiler Target Setpoint: Space Heating:
The boiler target temperature is automatically
determined from Space Heating and DHW

requirements. Space heating is based on outdoor reset.

When both a Heat Call and a DHW Call are present
at the same time, the control operates to provide the

higher boiler target temperature.

Heating Curve (Outdoor Temperature Reset)

The control uses a linear heating curve to calculate

a target setpoint. The following data are used

to calculate the target setpoint from the outdoor

temperature.

1. The heating curve or reset ratio (RR) is set by

the potentiometer with a range of 0.4 to 3.6.

2. The room temperature is xed at 70 deg F.

3. Boiler target = 70 deg F + RR x (70 deg F -

outdoor temp)

Table 9. Boiler Target Temperature

DHW Operation The boiler target for DHW

calls is xed at 180 deg F.
Note: There is no control of a DHW pump, so the
boiler pump runs with the call for DHW.

Limiting The boiler target is limited to a

minimum and a maximum target to ensure that the

water temperature does not exceed the limits.

1. Target Min - The boiler target minimum is

the point at which the stages will start to turn on to

maintain a minimum water temperature. The Boiler
Minimum water temperature is 130 deg F, regardless
of other calculated targets. To ensure that the water

temperature is greater than the Boiler Minimum water
temperature the target is increased to allow the stages
to cycle on by the Boiler Minimum water temperature,

Page 30

Bradford White Corp

Boiler Minimum target is set to Boiler Minimum +
dierential/2.

2. Target Max - The boiler target maximum is

the point at which the stages will start to turn o to
maintain a maximum water temperature. The Boiler

Maximum water temperature is set by setting dip

switch #4: Boiler Maximum 210°F (O) / 190°F (On).

To ensure that the water temperature is less than

the Boiler Maximum water temperature the target is

decreased to allow the stages to cycle o by the Boiler

Maximum water temperature, Boiler Maximum target

is set to Boiler Maximum - dierential/2.

Automatic Dierential The control has the

ability to adjust the low and high of it's temperature

range (the dierential) to prevent short cycling and
maximize the lifetime of components. As the load
increases, the dierential will decrease to minimize
temperature swings. As the load decreases, the
dierential will increase to prevent short cycling.

The term 'automatic' refers to the control
adjusting the water temperature to allow the burner to

re only when the control determines that the inferred

heat load cannot be met by the residual heat of the

water in the boiler.

WWSD Operation Warm Weather Shutdown -

WWSD feature is selected via dip switch #3, WWSD
Inactive (O) / Active 70°F (On). WWSD point is
xed at 70°F. Control exits WWSD when the outdoor
temp falls to 65°F. When there is a call for HEAT
and the control is in WWSD the HEAT call will be
ignored. When there is a call for DHW and the control
is in WWSD the DHW call will be satised. WWSD
LED turns on when control detects WWSD.

Summary of Input Sensors:

1. Outdoor sensor - monitors the outside air

temperature for outdoor reset mode

2. Boiler outlet sensor -monitors the water

temperature of the boiler outlet supply

3. System Supply sensor - monitors the water

temperature of the system supply

The boiler outlet sensor is required at all times.

If the boiler outlet sensor has any fault then the control

will ash an error and turns all stages o. The system

supply sensor is optional and utilizes

primary / secondary piping. If the system supply
sensor has a fault then the control ashes an error

message and operates using the boiler outlet sensor

(system supply = boiler outlet).

1. Connect the system sensor on the SYS and COM
terminals.

2. Install the sensor into a well in the location used to
control water temperature.

3. Set DIP switch jumper positions as follows:

1 ON
2 OFF
3 OFF
4 ON
5 OFF

Table 10. DIP Switch Settings

4. The system pump will only operate with a call for
heat. The HH or CH terminals must be jumpered to
run the pump constantly.

5. The boiler setpoint may now be controlled by the
potentiometer knob on the control.

6. The operating setpoint is 150°F min to 210°F max.

7. The setpoint dierential will be automatically
adjusted by the controller. The actual temperature

may overshoot the setpoint initially, but the control
logic will minimize this throughout the operating

cycles of the boiler.

6.B.2 Operating Temperature Control on

Volume Water Heaters

Volume water heaters use a simple aquastat for
2-stage or on/o control. When setting your set point

temperature keep in mind the control is sensing the

inlet water temperature. The manual reset high limit,
which is xed at 200F, senses the outlet temperature.
Based on the ow characteristics of the installation,
the controller will need to be set no higher than 175F
(200F - Delta T = Max set point). To avoid nuisance
lockouts, reduce the set point even further.

On a 2-stage controller, set the desired operating

set point. The controller has an interstage dierential
that can be adjusted from 3°F to 10°F, which allows

the user to have some control over how stage 2 and

stage 1 call for heat. See Figure 18

6.C External Boiler Operations

Use the eld interlock terminals located in the
control box area. Remove the jumper and attach your
"T-T" or "CH" demand here.

Using the system Sensor:

The system sensor can be used to control the
setpoint of a primary loop in a primary/secondary
system, or can be used to control an indirect water tank

temperature. To setup the use of the system sensor, do

the following:

*1 Difference between the temperatures at which the two switches
make R-W. Adjustable from 3°F to 10°F (1.7°C to 5.6°C).

*2 Two DPDT switches operate in sequence. Each switch

differential is fixed at approximately 3°F (1.7°C).

Figure 18. Two stage aquastat

6.D Sequence of Operation

If a eld-supplied pump is properly wired to the

unit, or if the unit is pump-mounted, the pump will be

energized.

Once the water ow switch makes, if all of the

safety interlocks are closed, the ignition module will

energize the blower(s) for a 15-second pre-purge,

followed by a 40-second period to allow the ignitor to

heat.

The ignition control energizes the blower. The

blower pressurizes the air box (which supplies air to
the burners) and closes the normally-open contact

on the airow pressure switch. The blocked vent

pressure switch senses the pressure in the exhaust

plenum. This switch opens if the pressure is excessive
(as an indicator of a blocked vent). When these two

pressure switches are closed, voltage is sent to the
PSW terminal on the ignition control, which allows the

ignition module to proceed with the ignition sequence.

If the airow proving circuit is not proven,
ignition module will lock out. Section 6.5 describes
the result of air ow faults in more detail.

When the ignition control gets the signal at the

PSW terminal, it will energize its MV terminal, which
sends power to the stage one (or on/o) main valve.

After a 7-second trial for ignition, the ignitor
switches to ame sense mode. If a ame is not

monitored by the Brute Deluxe ignition control, at the

control’s PSW terminal.

control sees power at PSW for 30 seconds, but the

combustion blower has not yet been energized by the

control (F1 and F2), the ignition control will remain
in this fault mode, with the blower o. If the power to

PSW is removed while there is still a call for heat, the
ignition sequence will start again, but the main valves
will not be energized until PSW sees power during the

ignition sequence.

is ring, the control will immediately de-energize the gas
valve terminal (MV). The blower will remain on for
the post-purge period (45 seconds), and the control
will continue to monitor the PSW input. If the signal

is detected during the post-purge period, a normal trial

for ignition will begin, starting with the 15-second
pre-purge. If the signal is not detected during the post­purge, the control will lockout with the blower o.

label and turn on gas and electrical power to

appliance.

4. Switch on the appliance power switch located on
the right side of the unit.

5. The Brute Deluxe will enter the start sequence,
as long as the unit is being called for heat. The

blower and pump come on for pre-purge, then
the ignitor warm-up sequence starts and after
the ignitor warm-up is complete and all safety

devices are veried, the gas valves open. If

ignition doesn’t occur, check that there is proper

gas supply. Wait 5 minutes and start the unit again.

During initial start up, air in the gas line may
cause the Brute Deluxe to "lock out" during the

rst few trials for ignition. If the ignition control
locks out, reset by cycling the power o and on

using the main power switch on the right side of

the cabinet.

6. When the unit is running, the supply gas pressure
must be checked. Inlet gas pressure must not
exceed 10.5 in. w.c. (2.5 kPa) for Natural Gas and
13 in. w.c. (3.2 kPa) for LP. The minimum inlet
gas pressure is 4 in. w.c. (1.2 kPa) for Natural Gas
and 8 in. w.c. (2 kPa) for LP. See Table 11

7. Once the inlet gas pressure is veried, the outlet

gas pressure from each valve (manifold gas
pressure) must be checked, and adjusted, if

necessary. The manifold gas pressure must be 3.0
in. w.c. (0.62 kPa) for natural gas and 9.0 in. w.c.
(2.2 kPa) for LP. Also See Table 11

8. Set the air box pressure to 1" w.c. adjusting air
shutter on the blower as a starting point. Then

adjust the shutter to get the required CO2%.
Closing the shutter will increase CO2%.
Opening the shutter will lower the CO2%

9. Complete the setup by checking the CO2 at the
outlet of the unit. The CO2 should be 8% for
natural gas, or 9.2% for LP.

10. After placing the appliance in operation, the

Burner Safety Shuto Device must be tested. To

test:

(a) Close gas shuto valve with burner operating.
(b) The ame will go out and blower will continue

to run for the post purge cycle. Three attempts to
light will follow. Ignition will not occur as the gas
is o. The ignition control will lockout, and will

have to be reset by cycling the power before the

unit will operate.

(c) Open gas shuto valve. Restart the appliance.

The ignition sequence will start again and the

burner will start. The appliance will return to its
previous mode of operation.

11. Check all heat exchanger water connections, ange

and header gaskets for watertight integrity 24

hours after commissioning. If there are any signs

of water leakage, re-torque fasteners or re-seat
threaded connections as necessary to eliminate

leakage.

6.F.2 High Altitude Adjustment and Set-Up

High altitude adjustment must not be made on

appliances operating at elevations below 2500 ft. (762 m).

No orice changes are required to adjust the

Brute Deluxe appliances for high altitude. High

altitude adjustment is accomplished by adjustment

of the air shutter. A CO2 or O2 analyzer is required to
make these adjustments.

Start the adjustment process by checking the CO2

in the “as installed” condition. Adjust the air shutter(s)

so that the CO2 is about 8% or the O2 is about 6.8%

for appliances operating on natural gas. For appliances
operating on LP Gas adjust the air shutter(s) so that the

CO2 is about 9.2% or the O2 is about 6.8%.

If the appropriate CO2 / O2 levels cannot be

achieved by adjusting the air shutter. Contact the

Technical Services Department at number shown on

back page.

The amount of derate will vary depending on

heating value of the fuel and the elevation at the

installation site.

Caution

Should any odor of gas be detected, or if the
gas burner does not appear to be functioning
in a normal manner, close main shutoff valve,
do not shut off switch, and contact your heating
contractor, gas company, or factory representative.

burners through the ignitor hole using a ashlight to
illuminate. If there is any indication of debris on the

burners that is visible, all the burners will need to be

inspected more thoroughly. Remove the gas manifold
assemblies and the burner assemblies. Inspect the
burners. Clean burners, if necessary, by blowing

compressed air from the outside of the burners into

the center of the burner. A dirty burner may be an

indication of improper combustion or dirty combustion

reverse order. Turn on manual gas shuto valve and

120 volt power and check appliance operation and

tightness of gas valve connections.

7.B.4 Manual Reset High Limit Control

The high limit switch is a manual reset, non-

adjustable switch with a remote bulb-type sensor.

Switches for water heaters and low temperature boiler

models are set at 200°F. Switches for standard boilers
are set at 240°F.

The control is located behind the front door, on a

panel in front of the blower. The probe is in the outlet
side of the header.

To reset the switch, unscrew the black cover that

is over the reset button, and push the button. Replace
the cover after the switch is reset.

To replace, shut o power to the appliance.
Remove the cover that is over the button, and remove
the nut that is around the button. Pull the control
through the panel, and remove the spade terminals.
Replace in reverse order.

7.B.5 Ignition Control

The ignition control controls the hot surface

ignitor and proves that the ame signal is appropriate
for powering the gas valves. It also controls the
blower’s pre-purge and post-purge.

To replace a control, shut o the 120-volt power
to the appliance. Remove the cover from the control
panel. Remove the electrical connectors from the
ignition control. Take out the controller’s mounting
screws, and pull the controller out. Replace in reverse
order.

7.B.2 Filter

The lter used in the Brute Deluxe is washable
and has an 80% arrestance rating. Since the lter is
washable, it will only need replacement occasionally.
If lter replacement is needed, it should only be
replaced with a factory part. Inspect the air lter
monthly, or more often in dirty environments. If there
is debris on the air lter, remove it from the lter
frame, and wash it with mild soap and water. Ensure
that the lter is completely dry before reinstalling.

To remove a valve, shut o 120-volt power
and the manual gas shuto valve. Remove the front
panels from the unit. Disconnect the wires to the valve.
Disengage the union and remove the valve. Pull the

pipe nipples from the inlet and outlet of the valve, and

clean the threads on the pipe nipples for reuse. Apply

new tape or pipe dope to the pipe nipples (threaded

7.B.6 Ignitor

The ignitor used is a 120v “Hot Surface” type.

It is energized whenever there is a call for heat and

switched o when ignition is established and the ame
has been sensed. To replace the ignitor, shut o the

120-volt power to the appliance, remove the ignitor/
burner access panel, disconnect the Molex connector,

remove the two mounting screws on the ignitor ange,
and pull the ignitor out. Install in reverse order, always

using a new ignitor gasket with the replacement

ignitor.

Caution

Ignitor gets hot. To avoid injury, handle the ignitor
with caution.

7.B.7 Transformer

The Brute Deluxe’s transformer is not capable
of supplying control voltage for external devices such
as zone valves, which must have their own separate

power supply. Should a transformer need replacing,
shut o the 120-volt power. Unplug the transformer

wires, remove the mounting screws and remove the
transformer. Replace transformer in the reverse order.

7.B.8 Flow Switch

The Brute Deluxe uses a paddle-type ow switch
to ensure that the unit has water ow before ignition is
allowed. To replace the ow switch, turn o the 120­volt power to the appliance. Isolate the boiler or water
heater from the system by closing the isolation valves.

Caution

Water may be hot enough to scald. Allow water to
cool before proceeding.

Attention

screws that attach the top to the side panels.
Remove the side panels.

7. Remove the heat exchanger from the unit.
NOTE: Heat exchangers are heavy and may

require two people to remove to avoid personal

injury.

8. Clean the heat exchanger: A light accumulation

of soot or corrosion on the outside of the heat

exchanger can be easily removed. Use a wire

brush to remove loose soot and scale from the

heat exchanger.

9. NOTE: While the heat exchanger is out of the
unit, inspect the rewall refractory insulation.
Replace if necessary.

10. Inspect the inside of the copper tubes for scale
buildup. Scale can build up on the inner surface

of the heat exchanger tubes, which can restrict

water ow. If the tubes show signs of scaling,
clean the internal surface.

11. Reassemble in the reverse order, and check
appliance operation after start-up.

NOTE: The warranty does not cover damage
caused by lack of required maintenance, lack of
water flow, or improper operating practices.

Release pressure in the system by actuating
the pressure relief valves or eld supplied boiler
drain valve. Remove cover from the ow switch
and disconnect the wires. Unthread the ow switch
from piping. Ensure the new ow switch paddles are

trimmed to the same size as the original paddles, and

reinstall in the reverse order. For boiler and other static

pressure systems, restore the system pressure to the

original setting, (or 10 psi minimum).

7.B.9 Heat Exchanger Coil

The Brute Deluxe has a premixed burner system.
These systems provide the burners with sucient air

for complete combustion, and black carbon sooting is

seldom experienced. If sooting is suspected, view ports

for inspection of the heat exchanger are provided on

the side of the boiler. In the unlikely event that there is

a buildup of black carbon soot or other debris on the
heat exchanger, clean per the following:

1. Disconnect the electrical supply to the unit.

2. Turn o the gas supply by closing the manual gas

valve on the heater.

3. Disconnect and remove the wires, conduit and

sensors from all components that are attached to

the inlet/outlet header.

4. Isolate the heat exchanger from the water supply.

5. Disconnect the header anges from the inlet and

outlet.

6. Allow the heat exchanger to drain. Remove the

venting and remove the top, by removing the

WARNING

Black carbon soot buildup on a dirty heat
exchanger can be ignited by a random spark or
flame thereby creating a risk of fire or explosion.
To prevent this from happening, dampen the soot
deposits with a wet brush or fine water spray
before servicing the heat exchanger.

AVERTISSEMENT

L’accumulation de suie sur un échangeur
thermique sale peut s’enflammer au contact
d’une étincelle ou d’une flamme et présenter un
risque d’incendie ou d’explosion. Afin d’empêcher
que cela se produise, humidifier les dépôts
de suie à l’aide d’une brosse mouillée ou par
une pulvérisation fine d’eau avant d’effectuer
l’entretien de l’échangeur thermique.

SECTION 8 Trouble Shooting

8.A Resolving Lockouts

There are many causes of lockouts. The three

most common causes are: (1) inadequate gas supply,

(2) poor combustion, (3) ignitor failure.

1. Inadequate gas supply: Before proceeding, ensure
that the gas supply has not been shuto or the LP
tank (LP boilers) is not empty. Then, restart the
boiler and observe the operational cycle. After
a 15-second fan pre-purge, the ignitor will heat
up for 40 seconds, and then the unit will light.

If it does not, check the gas supply pressure to
the appliance, after resetting the appliance and

attempting another start-up. The Natural gas
pressure to the appliance must be above 4 in. w.c.
(1.0 kPa) throughout the entire start-up cycle. See
Table 11. If it is not, correct the supply problem
(check gas valves or supply piping). If the supply

pressure is adequate, consult the factory for

assistance.

2. Poor Combustion: Poor combustion should be
suspected if there is a strong ue gas odor. The

odor may result from an improper gas/air ratio
(high or low O2 or CO2). Brute Deluxe appliances

operate best with 45% excess air (8% CO2 on
natural gas, 9.2% CO2 on LP). Check the CO2 of
the appliance and adjust if necessary.

3. Ignitor failure: If the boiler goes through a

normal start cycle but combustion does not

occur, ignitor failure should be suspected. Check

the ignitor by unplugging the ignitor plug and

measuring the ignitor resistance. It should be
50-80 ohms. If the resistance is not 50-80 ohms,
replace the ignitor. If the resistance is correct,
reset the boiler and check for 120 VAC at the
ignitor plug during the start cycle. If there is no

voltage, replace the faulty ignitor wire harness or

the ignition control.

8.B Delayed Ignition — Possible Causes

A defective burner can cause a delayed ignition.

If the gas supply pressure is proper and the gas
valves are functioning properly, then burners should

be inspected. There should be no distortion or

perforations in the burners outside of the active burner

port area. Replace if indicated.

8.C Short Cycling — Boiler

Boiler short cycling is caused when the load

on the boiler system swings rapidly causing frequent

cycling between call for heat and satised conditions.

This condition is greatly reduced on two stage

units. If short cycling is a problem, it may be due

to an oversized boiler, incorrect set points or a load

distribution problem. If desired temperature response

is not achievable without short cycling it may be

necessary to install a buer tank in the system. Contact

your Bradford White representative to discuss possible

remedies.

8.D Short Cycling — Water Heater

Short cycling will generally occur only in
combination space heating and water heating
applications when the water heater is operating in the

space-heating mode. If the heating load drops below

the minimum input of the water heater for an extended
period, the water heater will have a tendency to short

cycle. If short cycling is frequently experienced,

regardless of the control’s attempt to limit it, the

heating load should be redistributed to control it.

If short cycling occurs in a water heater
application, it is probably caused by undersized
piping between the water heater and the storage tank
or by some other factor that restricts proper water

ow through the water heater. The cause should be
determined and corrected.

8.E High Gas Consumption

Appliances operating with an improper air/fuel

ratio are very inecient and consequently, have very
high gas consumption. Because eciency is high when

the CO2 is high (or O2 is low), appliances operating
with low CO2 or high O2 (especially LP appliances)

consume more gas. Adjust the CO2 or O2 for optimum
eciency. If no combustion analyzing equipment (CO2

or O2) is available then a proper adjustment of the air/
fuel ratio (CO2 or O2) cannot be accomplished. The
CO2 should be 8% at high re for natural gas and 9.2%

at high re for LP. To check the CO2, rst verify that
the supply gas pressure is within 4.0 to 13 in. w.c. (1.0
to 3.2 kPa). See Table 11

With the Brute Deluxe running with all stages

ring, set the air box pressure to 1.8 in. w.c. (0.42 kPa)

(as a starting point), by adjusting the air shutter(s) at

the intake of the fan(s). Check the CO2, and adjust the

air shutters if further adjustment to the CO2 is needed.
