Locating the Appliance

Bradford White Corp.

2.1 Locating the Appliance

Brute Elite is for indoor, wall-mounted

installations only.

The appliance should be located to provide
clearances on all sides for maintenance and inspection.
It should not be located in an area where leakage of any
connections will result in damage to the area adjacent to

the appliance or to lower oors of the structure.

When such a location is not available, it is
recommended that a suitable drain pan, adequately
drained, be installed under the appliance.

The appliance is design certied by CSA-

International for wall-mounted installation in
basements; in closets, utility rooms or alcoves. The
location for the appliance should be chosen with regard
to the vent pipe lengths and external plumbing and
on a plumb (vertical) wall. The unit shall be installed
such that the gas ignition system components are
protected from water (dripping, spraying, rain, etc.)
during operation and service (circulator replacement,
control replacement, etc.). When vented vertically, the
Brute Elite must be located as close as practical to the
vertical section of the vent. If the vent terminal and/or
combustion air terminal terminate through a wall, and
there is potential for snow accumulation in the local
area, both terminals should be installed at an appropriate
level above grade or the maximum expected snow line.

The dimensions and requirements that are shown
in Table 1 should be met when choosing the locations
for the appliance.

2.2 Locating Appliance for Correct Vent

Distance from Outside Wall or

Roof Termination

The forced draft combustion air blower in the

appliance has sufcient power to vent properly when the

guidelines in Table 2 are followed.

NOTE: When located on the same wall, the Brute Elite
combustion air intake terminal must be installed a
minimum of 12" below the exhaust terminal.

SECTION 3.

Venting and Combustion Air

Bradford White Brute Elite includes a

standard CPVC vent/combustion air
adapter. If eld connections require
use of PVC/CPVC vent materials, the
installer must use proper adhesive to
join CPVC and/or PVC pipe and ttings.

3.1 Combustion Air

Brute Elite boilers and water heaters must
have provisions for combustion and ventilation air
in accordance with the applicable requirements for
Combustion Air Supply and Ventilation in the National
Fuel Gas Code, ANSI Z223 1; or in Canada, the Natural
Gas and Propane Installation Code, CSA B149.1. All
applicable provisions of local building codes must also

must not be less than the sum of the areas of all vent

connectors in the conned space.

Other methods of introducing combustion and
ventilation air are acceptable, providing they conform to
the requirements in the applicable codes listed above.

In Canada, consult local building and safety codes
or, in absence of such requirements, follow CAN/CGA
B149.

3.1.2 Ducted Combustion Air

The combustion air can be taken through the wall,
or through the roof. When taken from the wall, it must
be taken from out-of-doors by means of the Bradford
White horizontal wall terminal, shown in Table 3. See

Table 2 to select the appropriate diameter air pipe. When

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

elbow arrangement must be used to prevent entry of rain
water (see Figure 7).

Use ABS, PVC, CPVC or galvanized pipe for the
combustion air intake (see Table 4), sized per Table 2.
Route the intake to the boiler as directly as possible.
Seal all joints. Provide adequate hangers. The unit must
not support the weight of the combustion air intake pipe.
Maximum linear pipe length allowed is shown in Table

2. Subtract 5 allowable linear ft. (1.5m) for every elbow

used.

The connection for the intake air pipe is at the top
of the unit (see Figure 2).

3.2 Venting (Exhaust)

WARNING

Failure to use the appropriate vent material, installation
techniques, glues/sealants could lead to vent failure
causing property damage, personal injury or death.

WARNING

All venting must be installed according to this manual
and any other applicable local codes, including but

not limited to, ANSI Z223.1/NFPA 54, CSA B149.1,
CSAB149.2 and ULC-S636. Failure to follow this manual

and applicable codes may lead to property damage,

severe injury, or death.

The ue temperature of the Brute Elite changes

dramatically with changes in operating water
temperature. Therefore, it is necessary to assess the
application of the boiler to determine the required

certied vent class. If the Brute Elite is installed in

an application where the ambient temperature is
elevated, and/or installed in a closet/alcove, CPVC

or stainless steel material is required. If the system

temperatures are unknown at the time of installation,
stainless or CPVC material is recommended.

The Brute Elite is a Category IV appliance and
may be installed with PVC and CPVC that complies
with ANSI/ASTM D1785 F441, or a stainless steel
venting system that complies with UL 1738 Standard
(see Table 5).

IN CANADA all venting used must meet the

following requirements:

1. ULC-S636 certied and marked

2. The rst 3 feet of venting must be accessible for

visual inspection.

3. All components used in the vent system must be
from a certied manufacturer.

4 . Vent system components must not be mixed

with alternate manufacturers certied

components and/or unlisted components.

5 . The venting must be installed according to the

vent manufacturers installation instructions.

The unit’s vent can terminate through the roof, or

through an outside wall.

See Table 2 to select the appropriate vent pipe

diameter. Vent pipe must pitch upward, toward the vent
terminal, not less than 1/4" per foot, so that condensate
will run back to the Brute Elite to drain. Route vent
pipe to the heater as directly as possible. Seal all
joints and provide adequate hangers as required in the
venting system manufacturer’s Installation Instructions.
Horizontal portions of the venting system must be
supported to prevent sagging and may not have any low
sections that could trap condensate. The unit must not
support the weight of the vent pipe. Please see Table 2
for proper diameter vs. length allowed.

INSTALLATIONS IN CANADA require the use

of venting material certied to ULCS636. All Gas

vents connected to the Brute Elite, plastic, stainless

steel or otherwise must be certied to this ULC

standard. Appropriate selection of vent material is
very important for proper performance and safe
operation of the Brute Elite.

The ue temperature of the Brute Elite changes

dramatically with changes in operating water
temperature. Therefore, it is necessary to assess the
application of the boiler to determine the required

certied vent class. If the Brute Elite is installed in

an application where the outlet water temperature

exceeds 145°F, and/or installed in a closet, class IIB
or higher vent material is required. If the system

temperatures are unknown at the time of installation,

class IIB or higher venting material is recommended.

IMPORTANT NOTE ABOUT COMMON VENTING: A

single vent that is shared by multiple Brute Elite units
MUST be engineered by a competent venting specialist,

and involves the selection of draft inducing equipment,

hardware and controls to properly balance ue gas
pressures. Do not common vent Brute Elite units

unless the vent system meets this requirement.
Brute Elite units are never permitted to share a vent
with Category I appliances.

3.3 Locating Vent & Combustion Air

Terminals

3.3.1 Side Wall Vent Terminal

The appropriate Bradford White side wall vent
terminal must be used. The terminal must be located in
accordance with ANSI Z223.1/NFPA 54 and applicable
local codes. In Canada, the installation must be in
accordance with CSA B149.1 or .2 and local applicable
codes. Consider the following when installing the terminal:

1. Figure 9 shows the requirements for mechanical

vent terminal clearances for the U.S. and Canada.

2. Vent terminals for condensing appliances or

appliances with condensing vents are not permitted

to terminate above a public walkway, or over an

area where condensate or vapor could create a

nuisance or hazard.

3. Locate the vent terminal so that vent gases cannot

be drawn into air conditioning system inlets.

4. Locate the vent terminal so that vent gases cannot

enter the building through doors, windows, gravity

inlets or other openings. Whenever possible, avoid

locations under windows or near doors.

5. Locate the vent terminal so that it cannot be

blocked by snow. The installer may determine

that a vent terminal must be higher than the

minimum shown in codes, depending upon local

conditions.

6. Locate the terminal so the vent exhaust does not

settle on building surfaces or other nearby objects.

Vent products may damage surfaces or objects.

7. If the boiler or water heater uses ducted

combustion air from an intake terminal located on

the same wall, see Figure 9 for proper spacing and

orientation.

If the vent termination is located in an area
exposed to high winds, an optional PVC tee (the same
diameter as the vent pipe) may be used. The tee'd vent
termination offers greater protection from wind related
operating issues.

of corrosive chemical fumes (e.g., cleaning uid,

chlorine compounds, etc.)

2. Locate the terminal so that it will not be subject
to damage by accident or vandalism. It must be at
least 7 feet (2.1m) above a public walkway.

3. Locate the combustion air terminal so that it cannot
be blocked by snow. The National Fuel Gas Code
requires that it be at least 12 inches (30cm) above
grade, but the installer may determine it should be
higher, depending upon local conditions.

4. For concentric vent, follow instructions

included with vent kit.

5. Multiple vent kits should be installed such that the
horizontal distance between outlet group and inlet
group is 36" (90cm) minimum.

6. Vent outlet must be no lower than the center of
the air inlet, and must be at least 12" (30cm) away
from the air inlet (see Figure 8).

3.3.3 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 7).

3.3.4 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 7). 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.

3.3.2 Side Wall Combustion Air Terminal

The Bradford White side wall combustion air
terminal, or concentric terminal (see Table 3), must
be used when the heater takes air from a side wall.

3.4 Common Vent Test

NOTE: This section does not describe a method for

common venting Brute Elite units. It describes what
must be done when a unit is removed from a common
vent system. Brute Elite units require special vent
systems and fans for common vent. Contact the factory
if you have questions about common venting Brute Elite
units.

When an existing boiler is removed from a
common venting system, the common venting system is
likely to be too large for proper venting of the appliances
remaining connected to it.

At the time of removal of an existing boiler, the
following steps shall be followed with each appliance
remaining connected to the common venting system
placed in operation, while the other appliances
remaining connected to the common venting system are
not in operation.

1. Seal any unused openings in the common venting

system.

2. Visually inspect the venting system for proper

size and horizontal pitch and determine there is no
blockage or restriction, leakage, corrosion and other

deciencies which could cause an unsafe condition.

3. Insofar as it is practical, close all building doors and

windows and all doors between the space in which
the appliances remaining connected to the common
venting system are located and other spaces of the
building. Turn on clothes dryers and any appliance
not connected to the common venting system.
Turn on any exhaust fans, such as range hoods and
bathroom exhausts, so they will operate at maximum
speed. Do not operate a summer exhaust fan. Close

The Brute Elite 125

replace dampers.

4. Place in operation the appliance being inspected.
Follow the lighting instructions. Adjust thermostat
so the appliance will operate continuously.

5. Test for spillage at the draft hood relief opening
after 5 minutes of main burner operation. Use

the ame of a match or candle, or smoke from a

cigarette, cigar or pipe.

6. After it has been determined that each appliance
remaining connected to the common venting system
properly vents when tested as outlined above, return

doors, windows, exhaust fans, replace dampers and

any other gas burning appliance to their previous
conditions of use.

7. Any improper operation of the common venting
system should be corrected so that the installation
conforms to the National Fuel Gas Code, ANSI
Z223.1/NFPA 54 and/or CSA B149.1, Installation
Codes. When resizing any portion of the common
venting system, the common venting system
should be resized to approach the minimum size
as determined using the appropriate tables and
guidelines in the National Fuel Gas Code, ANSI
Z223.1 NFPA 54 and/or CSA B149.1, Installation
Codes.

SECTION 4.

Gas Supply and Piping

4.1 Gas Supply and Piping

Gas piping should be supported by suitable

hangers or oor stands, not the appliance.

Review the following instructions before

proceeding with the installation.

1. Verify that the appliance is tted for the proper type

of gas by checking the rating plate. Brute Elite will
function properly without the use of high altitude

modication at elevations up to 10,000 feet (3050

m).

2. The maximum inlet gas pressure must not exceed
13" W.C. (3.2kPa). The minimum inlet gas
pressure is 4" W.C. (1.0kPa).

3. Refer to Tables 6A, 6B, 6C and 6D to size piping.

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

5. Locate and install manual shutoff valves in
accordance with state and local requirements.

6. A sediment trap must be provided upstream of the
gas controls.

7. All threaded joints should be coated with

piping compound resistant to action of liqueed

petroleum gas.

8. The appliance and its individual shutoff valve must
be disconnected from the gas supply piping during
any pressure testing of that system at test pressures
in excess of 1/2 PSIG (3.45kPa).

9. The unit must be isolated from the gas supply
system by closing its individual manual shutoff
valve during any pressure testing of the gas supply
piping system at test pressures equal to or less than
1/2 PSIG (3.45kPa).

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

11. Purge all air from gas lines.

when rigid hangers are installed. Maintain 1" (2.5cm)
clearance to combustibles for hot water pipes.

Pipe the discharge of the pressure relief valve (full
size) to a drain or in a manner to prevent injury in the
event of pressure relief. If system contains more than
24 gallons (91 liters), then an auxiliary expansion tank

is required. Minimum ll pressure must be 12psig

(82.7kPa). Install shutoff valves where required by code.

Suggested piping diagrams are shown in Figures

12 through 19. These diagrams are meant only as a

guide. Components required by local codes must be
properly installed.

Brute Elite's efciency is higher with lower

return water temperatures.

Brute Elite MUST be piped in a primary-secondary
fashion (using either piping or a hydraulic separator)
such that the pump that is mounted on the boiler ONLY
serves the boiler.

Brute Elite boiler must be located within 15 feet
(4.6m) of the supply and return header (or the hydraulic
separator). The pump is sized for a maximum of 30 feet
(9.1m) of piping and the headloss of the boiler only.

For custom congurations, the available pump

head is provided in Figure 11. The system designer
should take into account allowable boiler temperature
rise of 65°F (36°C).

6.1 Central Heat System Piping

NOTE: This appliance must be installed in a closed

pressure system with a minimum of 12 psi (82.7kPa)
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

6.2 Cold Water Make-Up

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.

which could result in leaking or ooding conditions.

Do not use automotive antifreeze or ethylene
glycol. To help prevent freezing, Bradford White
recommends the use of inhibited propylene glycol
concentrations between 20% and 35% glycol. Typically,
this concentration will serve as burst protection for
temperatures down to approximately -5°F (-20°C). If
temperatures are expected to be lower than -5°F (-20°C),
glycol concentrations up to 50% can be used. NOTE:

Bradford White supplied pumps are not all capable
of maintaining the reduced temperature rise required

6.3 Freeze Protection

Brute Elite units are certied for indoor use only,

and are not design-certied for placement outdoors.

Proper precautions for freeze protection are
recommended for boiler installations in areas where the
danger of freezing exists.

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

with glycol concentrations greater than 35%.

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
specications, or the glycol manufacturer, for information
about specic products, maintenance of solutions, and
set up according to your particular conditions.

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 which

may result in bursting of pipes, or damage to the boiler,

6.4 Suggested Piping Schematics

Figures 13 through 19 show suggested piping

congurations for Brute Elite boilers. These diagrams

6.6 Hot Water Piping

6.6.1 Domestic Hot Water Piping (BLMC)

Connect domestic hot and cold water piping to the
boiler at locations noted in Figure 13. Expected DHW
performance is indicated in Table 8.

Use of ow restrictor is optional to prevent colder
water at excessive ow rates. Contact Bradford White
for alternate congurations.

6.6.2 Indirect Water Heater Piping (BLMH)

The BLMH model can control an indirect water
heater zone. Pipe to the locations shown in Figure 13.
Zone valve and associated wiring are not required.
Setpoint is made via aquastat located on the indirect
water heater, or can be controlled at the boiler via a
remote sensor.

Page 17

6.7 Condensate Drain

A condensate drain trap is built into the Brute Elite.
Connect a 3/4” PVC pipe between the drain

connection and a oor drain (or a condensate pump if a
oor drain is not accessible).

The condensate drain must be installed so
as to prevent accumulation of condensate. When
a condensate pump is not used, the tubing must
continuously slope downward toward the drain with no
spiraling.

Consult local codes for the disposal method.

Caution

Condensate is mildly acidic (pH=5), and may harm
some oor drains and/or pipes, particularly those
that are metal. Ensure that the drain, drainpipe,
and anything that will come in contact with the
condensate can withstand the acidity, or neutralize
the condensate before disposal. Damage caused by

failure to install a neutralizer kit or to adequately
treat condensate will not be the manufacturer’s
responsibility.

SECTION 7.
Electrical Connections

WARNING

The appliance must be electrically grounded in

accordance with the requirements of the authority having
jurisdiction or, in the absence of such requirements, with
the latest edition of the National Electrical Code, ANSI/
NFPA 70, in the U.S. and with latest edition of CSA
C22.1 Canadian Electrical Code, Part 1, in Canada. Do
not rely on the gas or water piping to ground the metal
parts of the boiler. Plastic pipe or dielectric unions may
isolate the boiler electrically. Service and maintenance
personnel, who work on or around the boiler, may be
standing on wet oors and could be electrocuted by an
ungrounded boiler. Electrocution can result in severe
injury or death.

Single pole switches, including those of safety
controls and protective devices must not be wired in a
grounded line.

All electrical connections are made on the terminal
blocks that are located inside the control panel.

NOTE: All internal electrical components have been

prewired. No attempt should be made to connect
electrical wires to any other location except the terminal
blocks.

Wiring connections are shown in Figures 21-22.

Important Note: DO NOT MAKE/BREAK Brute Elite
LINE VOLTAGE TO SIGNAL CALL FOR HEAT. A “call
for heat / end call for heat” MUST be connected to the
eld interlock terminals. Some Brute Elite components

are designed to have constant voltage during normal

operation. If the Brute Elite's supply voltage is toggled

as a call for heat signal, premature failure of these

components may result.

If using remote 4-20mA control, Brute Elite does not
recognize 4mA as a signal to shut off. If the call for heat
is not connected between the eld interlock terminals,
Brute Elite will remain in low re when it sees 4mA as a
modulating signal.

Caution

Brute Elite supply voltage must not be disengaged,
except for service or isolation, or unless otherwise
instructed by procedures outlined in this manual. To
signal a call for heat, use the 24V eld-interlock, as
shown in the wiring diagram(s).

7.1 Main Power

Plug power cord into a non-switched 115V
electrical outlet with 15A circuit protection. FLA is
2A. There is an internal 10A breaker to protect internal
system components.

7.2 Pump Connections

Brute Elite energizes the integral boiler pump (and

three-way valve if central heat) upon a call for heat.

Once the call for heat is satised the pump will remain
on for the dened pump overrun time.

NOTE: System pump contacts are dry contacts.
Appropriate voltage must be supplied to the System
pump for proper operation.

System pump connections are located in the
control panel (see Figure 20). The system pump contacts
are rated for 120Vac, 7.4 amps. To use the contacts,
power must be supplied on one terminal with the other
terminal wired to the pump or a relay controlling the
pump.

7.3 24Vac Transformer with Circuit Breaker

24Vac is supplied by a transformer mounted behind
the upper door. All 24Vac power is supplied

through a

2A circuit breaker located behind middle door.

7.4 Central Heat - Call for Heat

Connect the Call for Heat to terminals #1 and #2
(connections labeled "T-T or interlock").

7.5 Outdoor Air Temperature Sensor

Connect the outdoor air temperature sensor
to connections labeled "Outdoor temp sensor." The
outdoor air temperature sensor is used for warm weather
shutdown and outdoor reset.

7.6 Domestic Hot Water Connection

For BLMH and indirect water heater, connect
aquastat for remote sensor to terminals 7 & 8 (see

Figures 20 and 22).

7.7 System Sensor

(lead lag/cascading operation only)

Connect the system sensor to connections labeled
"system sensor."

7.8 External Control Connections

Connect 4-20mA signals from external controls
or building automation systems. When making the
connections, follow the polarity designations shown on
the label.

7.9 Lead Lag / Cascading Wiring

Connections

Connect each boiler in the cascade system together
by daisy chaining each control from Modbus port 1

(MB1) of the rst boiler to the second and so on. This

can be done using 22awg or thicker shielded twisted pair
wire with drain. Two twisted pairs or three conductors
are needed.
a. To daisy-chain the boilers connect a wire from

Modbus port 1 (MB1) terminal A of the rst boiler

to Modbus port 1 (MB1) terminal A of the second

boiler.

Page 24

b. If there are more boilers in the system connect a

wire from Modbus port 1 terminal A of boiler 2 to
Modbus port 1 terminal A of boiler 3.

c. Repeat these steps until all Modbus port 1 terminal

A connections are wired.

d. Repeat the above steps for Modbus port 1 terminal

B and C connections to complete the wiring.

e. Connect the drain wire from the twisted pair wire

to ground on one end of the wire only.

7.10 Wiring Diagrams (see Figures 21-22)

SECTION 8.

Control Setup and Operation

The Brute Elite control is an integrated electronic
control that replaces many of the individual components
found on older appliances. The control acts as the
ignition control, pump control, high limit and cascading/
lead lag control and is setup using the digital display on
the appliance.

8.1 Digital Display Navigation

Figure 23. The USER INTERFACE.

The Digital Display is centered in the middle of
the User Interface and has 3 seperate modes of control.
They are USER, SETUP and DIAGNOSTIC. The names
of these modes clearly labels the intent of the different
levels of control. A USER might be the homeowner or
a service technician. SETUP displays all the controls
needed when setting up or expanding the boiler. And
DIAGNOSTIC is intended for a trained Brute Elite
technician. The menu structure and variables in each are
shown in Table 9, Table 10, and Table 11.

USER Mode is the home screen shown on the
control. If the display is not in USER Mode wait for the
display timeout period to be reached or press the Done
button to return to the USER Mode.

SETUP Mode is accessed by holding the up and
down arrow keys simultaneously for 3 seconds.

DIAGNOSTIC Mode is accessed by holding the
NEXT button for 3 seconds

Once in a particular Mode, navigation consists of
pressing the next button to scroll from item to item and
then pressing the up and down arrows to change values.
Once the value is adjusted, the NEXT or DONE button
can be pressed.

8.2 Ignition Control- Sequence of Events

1. Call for heat

2. Safety chain check

3. Fan starts.

4. Prepurge timer is started.

5. Pre ignition time of 2 seconds to check the ame

sensor operation and status.

6. Trial for ignition period, 4 seconds. The direct
spark ignition switches to constant spark for three
seconds, during which time the gas valve is open.
For the last second of the ignition period direct

spark is de-energized and the ame sensor checks
for established ame. If ame is sensed the control
enters "Run" to satisfy the demand. If ame is

not established the control enters a retry, starting

from step 2. If ame has not been established in

the appropriate number of retries the control will
lockout with a 109 error code.

7. Call for heat complete

8. Gas valve off

9. Fan and pump over run times active to purge the
system

The sequence is the same for DHW or Central

Heat modes. Upon a call for Central Heat, the 3-way
valve will shift position, allowing boiler water to enter
the building's heating loop.

8.3 Modulation Control

The control uses a PID algorithm to adjust

the ring rate of the boiler as the control point is

approached. The goal of the control is to operate

at a minimum ring rate to match the load on the

appliance. The burner modulates to achieve the setpoint
temperature, away from the actual off point.

8.4 Pump Control

The boiler pump is active anytime there is a call

for heat applied to the control. When there is a central
heat call supplied the system pump relay is active. If
there is a DHW call supplied while the central heat
call is active the system pump turns off. This happens
because of domestic hot water priority, which forces the
control to satisfy the domestic water demand prior to the

hydronic demand. When the last heat demand is satised

the boiler pump enters an overrun time.

8.5 High Limit

The control uses a dual thermistor sensor to

monitor the Brute Elite's maximum temperature. The
high limit sensor is installed in the outlet water. A dual
thermistor sensor is used, so that the two temperatures

can be monitored and compared to conrm accuracy.
The control will automatically reduce the ring of the

Brute Elite to prevent the high limit from tripping. The
high limit setpoint is not adjustable.

8.6 Stack Temperature

The stack temperature is a dual thermistor sensor
and is limit rated. The control compares each of the
temperature readings to determine accuracy. The stack
sensor is used as a limiting feature to avoid excessive
temperatures in the venting.

8.7 Domestic Hot Water Temperature

The domestic hot water temperature sensor is used
to control DHW temperature. The DHW setpoint can be
adjusted through the USER menu structure.

DHW setpoint is displayed during DHW mode.
For BLMH model, an aquastat will be used in lieu of a
sensor to control temperature of an indirect tank.

8.8 Lead Lag / Cascading

Lead Lag/Cascading allows multiple boilers to be
connected together and controlled from one common
sensor input. Up to 8 boilers can be connected together
in a single system. To setup Lead/Lag or cascading
operation there are several settings in the "setup"

menu structure that must be adjusted for the specic

installation, each is covered in the following sections.

8.8.1 Lead Lag Setpoint

The lead lag setpoint is set from the "user"
menu using the "LL" variable. This is the temperature
the boiler is attempting to maintain at the system
sensor. This setting doesn't control the boiler outlet
temperature, so the water temperature at the boiler
outlet may be much hotter than the system temperature
setpoint. Adjust the LL setpoint to the desired operating
temperature of the system.

8.8.2 Lead Lag Master/Slave Selection

In the SETUP menu structure, the "LL" menu
allows the lead lag system to be turned on and the boiler

to be congured as a master or slave control. In each

lead lag system there can only be one master control, so
proper selection is important to avoid operating issues.
To set the boiler to lead lag "master" operation the LL
menu should be set to "LDR". To set the boiler to slave,
"SLA" should be selected.

8.8.3 Lead Lag Address

The Lead Lag address must be set for each boiler
connected to the lead lag system. Each boiler must
have a unique address selected for the system to work
properly. Typically, the lead or master boiler should be
set to address one and the remaining boilers should be
set to values 2–8 depending upon how many boilers are
installed in the system.

8.8.4 Lead Lag Hysteresis

The lead lag system uses a hysteresis value set
in the setup menu, called, "HS". The hysteresis and
setpoint values control the on and off points of the
boiler. If the lead lag setpoint is adjusted to 120°F with
a hysteresis value of 5°F the boiler will turn off when
the water temperature reaches 125°F and will turn back

Page 28

Bradford White Corp.

on when the water temperature reaches 115°F. Set the
hysteresis values to match the boiler to the system
operating characteristics. Setting this value correctly
will help reduce the chance of short cycling.

8.8.5 Lead Lag Base Load Setting

The lead lag system uses a base load setting that is

set through the "setup" menu called "bL". The base load

setting identies the ring rate that the operating boiler

must achieve before the next boiler in the system is
allowed to operate. The default setting is 50% to avoid
short cycling and operating the boilers at higher, less

efcient, ring rates.

Table 12. Default Control Settings.

SECTION 9.

Modes of Operation

The Brute Elite control allows the boiler to operate
in many different modes of operation. The mode
must be selected based upon the requirements of the
installation. The following sections describe the basic
operation of the Brute Elite in each of the different
modes. Familiarize yourself with each mode and how
the operation of the boiler varies, depending upon the
installation and inputs the control is monitoring.

9.1 Hydronic Heating Demand

When using the Brute Elite for hydronic heating a
call for heat must be supplied to the "T-T or Interlock"
terminal. Once the call is supplied the control starts the
boiler and system pumps, shifts the 3-way valve position
and begins the ignition process. The ignition process
consists of a prepurge, trial for ignition, and run period.
The prepurge period starts on a call for heat once the fan
RPM reaches a preset level. The trial for ignition period
follows once the start-up RPM of the fan is reached. The
trial for ignition period lasts 4 seconds during which the
direct spark ignition system and gas valve are energized.

At the end of the trial for ignition period the ame signal
is compared with the preset ame threshold value. If
the ame signal is higher than the ame threshold the
Brute Elite enters "run". If the ame signal is below

the threshold the Brute Elite returns to prepurge and
starts the ignition process over. In "run" the Brute Elite

monitors the ame signal, call for heat, safeties, and

water temperatures and modulates as needed between
100% and 20% of rate to satisfy the call for heat.

9.2 Hydronic Heating with Outdoor Reset

Outdoor reset varies the control point setpoint
based on the actual outdoor temperature. The reset
function works as shown in Figure 24. When the
outdoor air temperature reaches the "high outdoor
temperature setpoint (HOD), the control point setting is
adjusted to the low boiler temperature setpoint (LBT).
When the outdoor air temperature reaches the low
outdoor temperature setpoint (LOD), the control setpoint
is adjusted to the CH/Outlet water setpoint temperature.
HOD, LOD and LBT can be adjusted by accessing
SETUP mode. CH setpoint is adjustable from the USER
menu structure.

9.3 Hydronic Heating Using External

Modulation Control

When using the Brute Elite for hydronic heating
with external modulation control a call for heat must
be supplied to the "T-T" terminal. Once the call is
supplied the control starts the boiler and system pumps
and begins the ignition process. In "run" the Brute Elite

monitors the ame signal, call for heat, safeties, and

The Brute Elite 125

Page 29

water temperatures. The boiler setpoint is used to limit
the maximum water temperature leaving the boiler only.
The modulation rate is controlled by a 4-20mA (0­10Vdc using converter) signal supplied by an external
control. When setting up a system using an external
control care must be taken to set the external control
algorithms to prevent the boiler from short cycling or
"hunting " to prevent premature component failure.

NOTE: A call for DHW will override external control.

9.4 Hydronic Heating Using Local Lead-

Lag/Cascading Feature

When using single or multiple Brute Elite's in lead-

lag conguration, the system sensor is used to monitor

the demand and modulation rates of the operating
system (see Section 7 for wiring instructions).

Let’s consider the following example:

Three Brute Elite boilers (let’s call them “Lead”,
“Slave1” and “Slave2”) tied together via Modbus
1 connection, with appropriate RMT Address (1, 2,

3). System sensor input is used to indicate common
secondary loop temperature.

System setpoint = 150°F

HS (hysteresis) = 10°F (default)

BL (base load) = 50% (default)

Anti-short-cycle = 5 minutes

Run sequence is initiated when system temperature
falls to 140°F (setpoint less hysteresis value). Lead

boiler will start. All ring rates will depend on several
application characteristics, including ow rate, system

load, water volume, etc. Boilers will start at a rate of
35%. If the load is such that Lead’s rate increases to
50%, “Slave1” will go through its startup sequence and

begin ring at 35%. At this point, both boilers (Lead and

Slave1) will continue to respond simultaneously to the
load/system characteristics, by modulating up or down
together, in relation to the relative system setpoint and
load characteristics.
Scenario 1: If the system loop temperature rises quickly,

and moves above setpoint, then the boilers will

simultaneously drop their ring rate. If when

reaching the point where both boilers drop toward

their minimum ring rate (20%), then the rst

slave will drop out. Slave1 will remain unavailable
until its ASC timer has expired (5 minutes). If
the load were to increase such to drive all active

boilers to 50% ring rate or more, during the ASC

time, Slave2 will begin its startup sequence and

begin to re at 35%, etc.

Scenario 2: If the system loop temperature continues

to drop (load increases), then the two boilers will

increase ring rate together. At 50%, Slave2 will
begin its ring sequence and be added to the group.

All three boilers will continue to re simultaneously at

equal input rates or…

1. Modulation rate approaches minimum ring rate
(20%), in which case Slave2 will rst drop out, and

then Slave1, accordingly.

2. System temperature reaches 10°F (HS- hysteresis
value) above setpoint (e.g. 160°F), in which case
remaining boiler will shut off.

3. Any of the boilers approach its high limit
temperature the individual boiler will modulate
back.

9.5 Warm Weather Shutdown

Warm weather shutdown overrides a central

heat call for heat when the outdoor air temperature is
greater than the warm weather shutdown setpoint. Warm
weather shutdown is always active whenever there
is an outdoor sensor attached to the control. To avoid
warm weather shutdown the warm weather shutdown
temperature should be increased as necessary. The warm
weather shutdown setpoint can be adjusted in SETUP
mode, using the SD menu.

9.6 Domestic Hot Water Demand

For Combi (BLMC), DHW demand is triggered

by a ow switch located near the DHW cold water
inlet. When water begins to ow (open faucet, shower,
etc.), the boiler will re, based on the water temperature

requirements. It may cycle on and off under very low

ow rates. Minimum ow is 0.5 gpm.

For BLMH, an optional indirect water heater can

be piped-in using Brute Elite's integral 3-way valve as
a zone valve. An aquastat in the indirect water heater

connected in place of the ow switch will signal demand

for DHW. The service person should note the minor
wiring differences on Figure 22.

SECTION 10.

Set Up Instructions

10.1 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. Move manual lever on 3-way valve actuator to
"open" position, allowing air to purge from boiler
loop. Valve is normally in DHW position until
there is a call for Central Heat via "T-T" contacts.
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.

Note that there is an air bleed located on the left

side of Brute Elite, on top of the jacket.

5. Cycle the boiler pump on and off 10 times, 10
seconds on and 10 seconds off to remove all air
from the heat exchanger. Then run system and
appliance pump for a minimum of 30 minutes with
the gas shut off.

6. Using manual lever located on left side of 3-way
valve actuator, move from "open" position back to
closed position repeatedly. This process forces air
out of the internal DHW loop.

WARNING

Failure to remove all air from the heat exchanger could
lead to property damage, severe injury or death.

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

8. 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.

9. Shut down the entire system and vent all radiation
units and high points in the system piping, as
described in Step 4.

10. 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.

11. 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.

12. 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.

13. 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. Main gas terminals will be energized,
attempting to light, for four (4) seconds, and then
will de-energize. The unit will go into lockout after
the required number of trial for ignition periods.

Second, turn the power off, press the manual reset

button on the boiler control, or the user display,
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.

14. Within three (3) days of start-up, recheck all air
bleeders and the expansion tank as described in
Steps 4 and 8 above.

Important Note: 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 qualied 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.

10.2 Starting the Burner after Set Up

Initial 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 boiler resulting from
improper setup is not covered by the limited warranty.

10.2.1 Burner Operation

REQUIRED TOOLS: differential pressure

gauge capable of reading negative 0.01 inches W.C.
(0.002kPa), screw drivers, and combustion analyzer.

1. Using this manual, make sure the installation
is complete and in full compliance with the
instructions and all local codes.

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 (Start Up / Shut Down
Instruction ) Decal, located on the back

of the Top Front Cover, and turn on gas
and electrical power to appliance.

The Brute Elite 125

Page 31

4. Brute Elite will enter the start sequence. Blower
and pump will energize for pre-purge, then the
ignition sequence starts. After all safety devices

are veried, the gas valve opens. If ignition doesn’t

occur, turn off the Brute Elite, check that there is
proper gas supply. Wait 5 minutes and start the unit
again.

5. Turn Brute Elite on.

6. After placing the appliance in operation, the
Burner Safety Shutoff Device must be tested:

(a) Close gas shutoff valve with burner

operating.

(b) Flame will go out and blower will continue

to run for the post purge cycle. One or three
additional attempts to light will follow

including pre-purge, ignitor on, valve/ame

on and post purge. Ignition will not occur
as the gas is off. The ignition control will
lockout.

(c) Open gas shutoff valve. Reset the boiler

control by pressing the RESET button on
the control or on the display. Restart the
appliance. The ignition sequence will start
again and the burner will start. The appliance
will return to its previous mode of operation.

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. Contact your heating contractor, gas
company, or factory representative.

10.2.2 Boiler Setup and Adjustment

1. Measure the CO2 in the ue products at high re.

The Brute Elite can be forced to high re to allow

for easier setup. Refer to Section 8.1, Table 11
for instructions on how to access the forced rate
menu. The CO2 readings should be between the
range shown in Table 13. If the CO2 is not within
the range shown, adjustments may be made.

To adjust the high re CO2, locate the high re
adjuster screw according to the appropriate gure.

Slowly make adjustments in 1/16 of a revolution
increments until the CO2 is within the range

identied.

2. Measure the CO2 in the ue products at low re.

Brute Elite can be forced to low re to allow for

easier setup. Refer to Section 8.1, Table 11 for
instructions on how to access the forced rate menu.
CO2 readings should be between the range shown
in Table 13. If the CO2 is not within the range
shown, adjustments may be made. To adjust the

low re CO2, locate the low re adjuster screw
according to the appropriate gure. Slowly make

adjustments in 1/16 of a revolution increments
until the CO2 is within the range identied

(see Figure 25).

3. Repeat steps 1 and 2 to conrm that the CO2

ranges are within the required ranges. High and
Low Fire CO2 settings should be approximately
equal. Adjust if necessary.

If any your CO2 readings cannot be adjusted

to the specied ranges (see Table 13), please

consult the factory for further information.

10.2.3 Manifold Pressure Check

1. Remove the cap that covers the manifold pressure
screw (See Figure 25). Loosen the manifold pressure
screw one revolution, and attach manometer.

2. Check Manifold pressure at high re using

manometer (see Table 13 for pressure range).

3. When nished, remove manometer, tighten screw,

and replace the cap.

If your pressure reading is not within the

specied range (see Table 13), please consult the

factory for further information.

WARNING

Improper adjustment may lead to poor combustion

quality, increasing the amount of carbon monoxide

produced. Excessive carbon monoxide levels may
lead to personal injury or death.

10.3 Shutting Down Brute Elite

1. Turn off the main electrical disconnect switch.

2. Close all manual gas valves.

3. If freezing is anticipated, drain Brute Elite and be
sure to also protect building piping from freezing.
All water must be removed from heat exchanger
and condensate trap or else damage from freezing
may occur.

This step to be performed by a qualied service person.

10.4 To Restart Brute Elite

If drained, follow Section 10.1 in this manual

for proper lling and purging.

1. Turn off the main electrical disconnect switch.

2. Close all manual gas valves.

3. WAIT FIVE (5) MINUTES.

4. Set the aquastat or thermostat to its lowest setting.

5. Open all manual gas valves.

6. Reset all safety switches (pressure switch, manual
reset high limit, etc.).

7. Set the temperature controller to the desired
temperature setting and switch on electrical power.

8. Burner will go through a prepurge period and
ignitor warm-up period, followed by ignition.

WARNING

Disconnect all power to the appliance before
attempting any service to the appliance. Contact with
electricity can result in severe injury or death.

11.1 System Maintenance

(yearly, unless otherwise noted)

1. If a strainer is employed in a pressure reducing
valve or the piping, clean it every six months.

2. Inspect the venting system for obstruction or
leakage at least once a year. Periodically clean the
screens in the vent terminal and combustion air
terminal (when used).

3. Keep the appliance area clear and free from
combustible materials, gasoline, and other

ammable vapors and liquids.

4. 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.

5. Low water cutoffs, if installed, should be checked
every year. Float type low water cutoffs should be

ushed periodically.

6. Inspect and clean the condensate collection system
yearly.

7. When a means is provided to neutralize
condensate, ensure that the condensate is being
neutralized properly.

8. Removal of burner door and inspection of

combustion coil and ue passages is required

at least once a year. Clean with a soft bristle
brush / vacuum or wash with water if necessary.
Sooting and buildup on the coils is an indication of
improper set up and poor combustion. Determine
the cause and make corrections.

9. Inspect the vent system and air intake system, and
ensure that all joints are sealed properly. If joints
need to be resealed, completely remove existing
sealing material, and clean with alcohol. Apply
new sealing material, and reassemble.

d. Blower i. Heat exchanger
e. Pump

11.2.1 Burner

Check the burner for debris. Remove the blower
arm assembly to access the burner. Remove the 4 bolts
connecting the blower to the arm (see Figure 32).
Remove the 5 bolts, which hold the burner arm in place.
Pull burner up and out. Clean burner, if necessary, by
blowing compressed air from the outside of the burner
into the center of the burner, and wipe the inside of the
burner clean with glass cleaner. A dirty burner may be an
indication of improper combustion or dirty combustion
air. Determine the cause, and correct. If damaged,
replace the burner gasket when replacing the burner.

NOTE: When installing the burner, make sure the ange
is aligned with the mating surface, as each is keyed to
control t.

11.2.2 Appliance Control

Brute Elite has an integrated control that
incorporates manual reset high limit control, operating
temperature control, modulating control, ignition
control, outdoor reset control, pump control and many
other features. If any of these features are thought
to be defective, please consult the factory for proper
trouble shooting practices prior to replacing the control.
If control replacement is required, turn off all power
to the appliance and shut off all manual gas valves to
the appliance. Remove the front door to the appliance
and the control panel plastic bezel. Remove all wire
connections from the control board. The control board
connections are keyed to only allow connection in the
proper location, but proper handling techniques should
be used to avoid damage to the wiring or connectors. To
remove the control push in on the two tabs on the left
side of the board to unlatch the clips from the control
panel. Rotate the control around the fastening points
on the right side of the control to remove the hooks
from the control panel. To replace the control repeat the
steps above in the reverse order making sure to connect
all wires in the proper location. Place the appliance in
operation following the steps outlined in Section 10.

11.2.3 Ignitor Assembly

The ignitor assembly is a two rod system that
consists of a ground rod and a sense rod. To remove the
ignitor assembly, shut off the 120 Volt power supply to
the appliance. Turn off all manual gas valves connecting
the appliance to the main gas supply line. Remove the
front door of the boiler to gain access to the ignitor
assembly. Remove the two wires connected to the
assembly. Then remove the two bolts connecting the
ignitor assembly to the burner door. Remove and replace
the old ignitor assembly gasket. Reinstall a new ignitor
assembly in the reverse order if the old assembly is
determined defective. Replace gasket if necessary.

11.2.4 Flame Sensor

The ame sensor is a single rod system. To replace

the ame sensor electrode, shut off the 120 Volt power

supply to the boiler. Turn off all manual gas valves
connecting the boiler to the main gas supply line.
Remove the front door of the boiler to gain access to the

ame sensor electrode. Remove the ame sensor wire

from the electrode. Remove the two bolts fastening the
electrode to the burner doors. Remove and replace the

old ame sensor gasket. Reinstall a new ame sensor

electrode in the reverse order if the old electrode is
determined defective.

Caution

Igniters and sensors get hot and

can cause burns or injury.

11.2.5 Blower

The combustion air blower is a high-pressure
centrifugal blower with a variable speed motor. Speed
of the motor is determined by the control logic. 120
Volts remain on to the blower at all times. If a blower
change is required, turn off the 120 Volt power and gas
supply to the unit. Take the front panel off. Disconnect
the 120 Volt and control signal connections from the
blower. Disconnect the bolts connecting the venturi to
the blower housing. Disconnect the fan outlet bolts from
the burner door blower arm. If the fan is determined
to be defective replace the existing fan with a new one
reversing the steps above. Make sure to install all of the
required O-rings and gaskets between the blower arm

and the blower and blower face and venturi ange.

11.2.6 Heat Exchanger Coils

Black carbon soot buildup on the external surfaces
of the heat exchanger is caused by one or more of the
following; incomplete combustion, combustion air
problems, venting problems and heater short cycling.
Soot buildup or other debris on the heat exchanger may

restrict the ue passages.

If black carbon soot buildup on the heat exchanger
is suspected, disconnect electrical supply to the unit,
and turn off the gas supply by closing the manual gas
valve on the unit. Access the heat exchanger through
the burner door at the front of the boiler, and inspect the

tubing using a ashlight. If there is a buildup of black

carbon soot or other debris on the heat exchanger, clean
per the following:

Caution

Black carbon soot buildup on a dirty heat exchanger
can be ignited by a random spark or ame. To prevent
this from happening, dampen the soot deposits with
a wet brush or ne water spray before servicing the
heat exchanger.

1. Shut off the 120 Volt power supply to the boiler

2. Turn off all manual gas valves connecting the

boiler to the main gas supply line.

3. Remove the four bolts connecting the blower

ange to the burner door arm.

4. Remove the nuts located on the outside diameter of
the burner door to the heat exchanger.

5. Remove the burner door/burner assembly from the
heat exchanger.

6. Disconnect the condensate drain line.

7. Attach a longer hose to drain and run to a bucket.

8. Clean the heat exchanger by brushing light
accumulations of soot and debris. Use a brush
with soft bristle (non metal) to avoid damaging the
surface of the heat exchanger tubes.

9. Once the tubes have been brushed clean rinse
the tubes and combustion chamber with a small
amount of water to rinse all of the debris out of

the bottom of the ue collector and into the longer

condensate trap line, which is being diverted into a
separate container.

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

WARNING

Failure to rinse the debris from the heat exchanger

and temporary drain line may lead to clogged

condensate lines, traps and neutralizers. Condensate
pumps (if used) may also be damaged from the
debris left behind, possibly causing property damage.

11. Install all components removed in
the reverse order to place the appliance back in
operation. Make sure all gaskets are in place as
components are installed. Replace any damaged
gaskets. Do NOT reuse damaged gaskets.

12. Place the appliance in operation according to

Section 10 checking all gas connections for leaks.

Conrm all fasteners are tight.

SECTION 12.

Trouble Shooting

12.1 Sequence of Operation

Brute Elite is a cold start appliance that should
start only on a call for heat from a tank aquastat, room
thermostat, zone valve end switch or other space

temperature control device (ow switch for DHW).

1. Upon a call for heat: (a) the internal pump and

system pump will start; (b) the blower will begin a

short pre-purge.

2. Following the prepurge cycle the direct spark

ignition will spark and will begin a 4 second

trial for ignition. The unit is allowed one or three

ignition retries.

3. The gas valve will then be energized and a reduced

rate ignition will occur. The unit will remain in a

reduced rate start-up period for several seconds.

4. After the reduced rate start time is over, the

unit will be in normal operation. Firing rate

will modulate based on the heating load via the

temperature controller settings and readings.

5. When the call for heat is complete, or the unit

reaches its setpoint temperature, the gas valve will

close, and the fan will continue to run for its post-

purge. If a pump delay time is used, the pump will

continue to run for the specied amount of time

(adjustable from 0.1 to 10 minutes).

12.2 Short Cycling

Because the Brute Elite is a modulating boiler,
and its input will decrease when there is a reduction
in heating load, short cycling is greatly reduced. If
the heating load drops below the minimum input of
the boiler for an extended period, the boiler will have
a tendency to short cycle. This can be a symptom of
improper control or piping layout. When in DHW mode
under low load conditions, the boiler will normally cycle
more often, but should not cycle frequently during call
for central heating.
