The forced draft combustion air blower in the
appliance has suf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
Brute Deluxe must be located as close as practical to
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.
The dimensions and requirements that are shown
in Table 2 should be met when choosing the locations
for the appliance.

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.
2.1 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.
2.1.1 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 3 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.

2.1.2 Intake 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 (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 2).
Use single-wall galvanized pipe, per Table
4, 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 4. 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.
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.
2.2.2 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.
2.2.3 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.
2.2 Venting
2.2.1 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
Category I vent system, and includes rules and tables
to size these vent systems. If the Brute Deluxe ’s

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.
AVERTISSEMENT
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 effective 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.
2.2.4 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 5.
Term Description
Pipe Must comply with UL Standard 1738 such
as Type AL29-4C Stainless Steel (either insulated or non-insulated).

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 3).
2.3.3 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 2).
2.3.4 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 2). 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.
2.4 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
Page 14
Bradford White Corp.
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 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.
2.4 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
2.5 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

SECTION 3. Gas Supply and Piping
3.1 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 off, 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 7, size supply.
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 0.5 psig (3.45 kpa).
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 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 4A. Water Connections — Brute Deluxe Boiler
4A.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 shutoff valves where required by code.
Suggested piping diagrams are shown in Figures
4, 5, 6, 7 and 8. These diagrams are meant only as a
guide. Components required by local codes must be properly installed.
4A.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 off 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 cutoff device either as a part
of the boiler or at the time of boiler installation.
4A.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.
4A.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
Brute Deluxe (200, 300, 400)
Page 17
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

SECTION 4B. Water Connections — Brute Deluxe Water Heater
4B.1 Water System Piping — Water Heater
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.
The Brute Deluxe can be used with several
different types of readily available storage tanks. A
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.
Suggested piping diagrams are shown in Figures
9, 10, 11 and 12. These diagrams are meant only as a
guide. Components required by local codes must be properly installed.
Note the recommended location of the temperature sensor on the diagrams. The Brute Deluxe
is shipped with an additional sensor that can be used
for more full-featured domestic water heating control.
To get these features, you must provide a location for
the additional sensor. It can be strapped to a pipe from 1" to 4" diameter, or inserted into a tank immersion well.
The minimum inlet water temperature for the
Brute Deluxe is 120°F (49°C) to avoid condensing on the copper coils.
4B.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.
4B.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 9 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.
4B.4 Combined Water Heating (potable)
and Space Heating — Water Heater
NOTE: These systems are not allowed in the
Commonwealth of Massachusetts.
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
Brute Deluxe (200, 300, 400)
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.
4B.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.

Operating Instructions
6.1 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 off.
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 shutoff device must be tested. First, shut off 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 off
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.
AVERTISSEMENT
N’utilisez pas cet appareil si l’une de ses pièces est passée sous l’eau. Appelez tout de suite un technicien en entretien et en réparation pour inspection de l’appareil et remplacement des pièces du système de commande, et des pièces de commande du circuit gaz, qui sont passées sous l’eau.

4. WWSD – On = Outdoor Reset AND WWSD Active AND control in WWSD; Flashes for outdoor sensor error, operation continues with xed boiler target of 140°F.
When a call for HEAT and/or DHW is present the pump contact (5A max) will be energized. Post purge can be selected via dip switch #5, Pump Post Purge Inactive (Off) /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 Off
there is no post purge of the pump, the pump turns off
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 off.
Pump Exercising The control exercises the
boiler pump every 3 days of inactivity. While the control is exercising the pump all LEDs will turn off 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 (Off) / 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 off when the water
outlet temperature reaches the Maximum setting that is elected via dip switch #4, Boiler Maximum
210°F (Off) / 190°F (On). Commercial boilers have dip switch #2 set for ‘Off’ 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)

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,
Boiler Minimum target is set to Boiler Minimum +

differential/2.
2. Target Max - The boiler target maximum is
the point at which the stages will start to turn off to
maintain a maximum water temperature. The Boiler
Maximum water temperature is set by setting dip
switch #4: Boiler Maximum 210°F (Off) / 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 off by the Boiler Maximum water temperature, Boiler Maximum target
is set to Boiler Maximum - differential/2.
Auto Differential The control automatically adjusts differential to prevent short cycling and
maximize the lifetime of components.
WWSD Operation Warm Weather Shutdown ­WWSD feature is selected via dip switch #3, WWSD Inactive (Off) / Active 70°F (On). WWSD point is xed at 70 deg 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 off. 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).
6.3 External Boiler Operations
Use the eld interlock ( T-T terminals ) that are inside control box.
6.4 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/off) main valve.
After a 7-second trial for ignition, the ignitor switches to ame sense mode. If a ame is not
detected, the gas valve will close and the ignition module will attempt ignition again (up to two more
times, for a total of three attempts.) If all three attempts fail, the ignition control will lock out.
If ame is sensed, the burner will continue to re as long as there is a call for heat, and none of the safety circuit is interrupted.
If there is a call for stage 2 on a 2-stage unit, that
valve will be energized.
If there is a loss of ame signal during a successful ring sequence, the ignition control will
remove power from the gas valves, and then attempt
to light up to two more times. If successful, the Brute Deluxe will re normally. If unsuccessful, the ignition control will lock out.
When the call for heat is satised, the gas valve(s) closes, and the blower starts a 45 second
post-purge, and the pump starts the post-purge (where
applicable).
6.5 Ignition Control Reaction to Air Flow /
Blocked Vent Pressure Switch
Air ow and blocked vent status are continuously
monitored by the Brute Deluxe ignition control, at the
control’s PSW terminal.
At the start of an ignition sequence, if the ignition
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 off. 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.
If the PSW signal is lost while the Brute Deluxe 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 off.

6.6 Operating the Burner and Set-Up
6.6.1 Set-Up for 0 to 2500 Feet Altitude
The setup must be checked before the unit is put
in operation. Problems such as failure to start, rough ignition, strong exhaust odors, etc. can be due to improper setup. Damage to the Brute Deluxe resulting
from improper setup is not covered by the limited
warranty.
1. Using this manual, make sure the installation
is complete and fully in compliance with the
instructions.
2. Determine that the appliance and system are lled with water and all air has been bled from both. Open all valves.
3. Observe all warnings on the Operating
Instructions 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 off 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 13 in. w.c. (3.2 kPa). The minimum inlet gas pressure is 5 in. w.c. (1.2 kPa) and 8 in. w.c. (2 kPa) for LP.
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.
8. Complete the setup by checking the CO outlet of the unit. The CO
should be 8% for
2
natural gas, or 9.2% for LP.
9. After placing the appliance in operation, the Burner Safety Shutoff Device must be tested.
To test:
(a) Close gas shutoff 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
at the
2
Page 29
will not occur as the gas is off. The ignition
control will lockout, and will have to be reset by cycling the power before the unit
will operate.
(c) Open gas shutoff 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.
10. 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.
6.6.2 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 CO
or O2 analyzer is required to
2
make these adjustments.
Start the adjustment process by checking the CO
in the “as installed” condition. Adjust the air shutter(s)
so that the CO
is about 8% or the O2 is about 6.8%
2
for appliances operating on natural gas. For appliances operating on LP Gas adjust the air shutter(s) so that the
is about 9.2% or the O2 is about 6.8%.
CO
2
If the appropriate CO
/ O2 levels cannot be
2
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.
Attention
Si vous sentez une odeur de gaz ou si le brûleur à gaz ne parait pas fonctionner de manière normale, fermez la vanne d’isolement, ne fermez aucun interrupteur, et appelez votre entreprise de chauffage, la compagnie de gaz ou un représentant du fabricant.

air terminal (when used).
4. Keep the appliance area clear and free from
combustible materials, gasoline, and other
ammable vapors and liquids.
5. If the appliance is not going to be used for
extended periods in locations where freezing normally occurs, it should be isolated from the
system and completely drained of all water. All
systems connected to it should also be drained or
protected from freezing.
6. Low water cutoffs, if installed, should be checked every 6 months. Float type low water cutoff should be ushed periodically.
7. Inspect ue passages, and clean with brushes/ vacuums, if necessary. Sooting in ue passages indicates improper combustion. Determine the cause and correct.
8. Inspect the vent system and air intake system,
and if the vent system is Category III, ensure
that all joints are sealed properly. If joints need
to be resealed, follow venting manufacturer's
instructions to clean and reseal vent system.
7.2 Appliance Maintenance and Component Description
Only genuine Bradford White replacement parts should be used.

7.2.1 Burners
Close main manual gas valve before proceeding.
Checking the burners for debris - Remove the ignitor/
burner access panel and ignitor, and inspect the
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
air. Determine the cause, and correct. Replace the burners in the reverse order.
7.2.2 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.
7.2.3 Gas Valves
The gas valves are designed to operate with
supply pressures of 4-13 in. w.c. (1.0 to 3.2 kPa).
To remove a valve, shut off 120-volt power
and the manual gas shutoff valve. Remove the front panels from the unit. Disconnect the wires to the valve.
Disengage the unions before and after the valve, 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 joints should be coated
with piping compound resistant to action of liqueed petroleum gas), and reinstall in reverse order. Turn
on manual gas shutoff valve and 120 volt power and check appliance operation and tightness of gas valve
connections.
7.2.4 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 off 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.
7.2.5 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 off 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.
7.2.6 Ignitor
The ignitor used is a 120v “Hot Surface” type.
It is energized whenever there is a call for heat and
switched off when ignition is established and the ame has been sensed. To replace the ignitor, shut off 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.
Attention
Le dispositif d’allumage devient très chaud. Manipulez le dispositif d’allumage avec précaution.
7.2.7 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 off the 120-volt power. Unplug the transformer
wires, remove the mounting screws and remove the
transformer. Replace transformer in the reverse order.
7.2.8 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 off 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
L’eau peut être chaude au point de vous brûler. Laissez refroidir l’eau avant d’intervenir.
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).
7.2.9 Heat Exchanger Coil
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.
2. Turn off 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
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.
The Brute Deluxe has a premixed burner system.
These systems provide the burners with suf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.

SECTION 8. Trouble Shooting
8.1 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 shutoff 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 gas pressure to the appliance must be above 5 in. w.c. (1.2 kPa) throughout the entire start-up cycle. 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 O
operate best with 45% excess air (8% CO natural gas, 9.2% CO 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.
8.2 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.

distribution problem. If desired temperature response
is not achievable without short cycling it may be
necessary to install a buffer tank in the system. Contact
your Bradford White representative to discuss possible
remedies.
8.4 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.
8.5 High Gas Consumption
Appliances operating with an improper air/
fuel ratio are very inefcient and consequently, have very high gas consumption. Because efciency is
high when the CO operating with low CO

8.3 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
