Please read this manual completely before proceeding
with the installation. If you have any questions
regarding this equipment, please consult the Bradford
White Corp. factory, or a local factory representative.
Many operating problems are caused by improper
installation.
1.2 Safety Notes
DANGER
• Water temperature over 125°F (52°C) can cause
severe burns instantly or death from scalds.
• Children, disabled and elderly are at highest risk of
being scalded.
• See instruction manual before
setting temperature at
heating appliance.
• Feel water before
bathing or showering.
• If this appliance is used
to produce water that
could scald if too hot,
such as domestic hot water
use, adjust the outlet
control (limit) or use temperature limiting valves
to obtain a maximum water temperature of 125°F
(52°C).
WARNING
Fire or Explosion Hazard
Improper conguration can cause fuel buildup and
explosion. Improper user operation may result in
property loss, severe physical injury, or death.
Any changes to safety-related conguration
parameters must only be done by experienced and/
or licensed burner/boiler operators and mechanics.
If any odor of gas is detected, or if the gas burner
does not appear to be functioning in a normal
manner, close the main gas shuto valve. Do not
shut o the power switch. Contact your heating
contractor, gas company, or factory representative.
e MagnaTech Appliance is protected against over-
pressurization. A pressure relief valve is included
with each MagnaTech.
e inlet gas pressure to the appliance must not
exceed 13” W.C. (3.2 kPa).
All installations must be made in accordance with
1) American National Standard Z223.1/NFPA54-
Latest Edition “National Fuel Gas Code” or 2) CSA
B149.1 “Natural Gas and Propane Installation Code”
and with the requirement of the local utility or other
authorities having jurisdiction. Such applicable
requirements take precedence over the general
instructions contained herein.
WARNING
Carbon Monoxide Hazard
Improper adjustment of the burners may lead to
poor combustion quality, increasing the amount
of carbon monoxide produced. Excessive carbon
monoxide levels may lead to personal injury or
death.

MagnaTech BOILERS AND VOLUME WATER HEATERS
Section 2
LOCATING THE APPLIANCE
2.1 Locating the Appliance
The MagnaTech may be installed indoors or
outdoors. If installing outdoors in a location
that may experience freezing temperatures,
precautions must be taken to prevent water in
the heat exchanger and condensate inside and
outside of the boiler from freezing. Damage due
to freezing water or condensate is not covered by
the warranty.
Choose a location for the unit which allows
clearances on all sides for maintenance and
inspection. See Table 1. Always install the unit on
a rm, level surface.
The unit 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 this type of location is not available,
install a suitable drain pan, adequately drained,
under the appliance.
The appliance is design-certied by CSA-
International for installation on combustible
ooring; in basements; in utility rooms or
alcoves. MagnaTech boilers must never be
installed on carpeting. The location for the
appliance should be chosen with regard to the
vent pipe lengths and external plumbing.
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 MagnaTech 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 Correct Vent Distance from
Outside Wall or Roof Termination
1.7 Unpacking
The MagnaTech is shipped in a single crate.
Remove all packing and tie-down materials.
Note - When located on the same wall, the
MagnaTech combustion air intake terminal must be
installed a minimum of 12” (30cm) below the exhaust
terminal. There must also be a minimum horizontal
distance from intake to the exhaust terminal
of 84” (213cm) See Figure 4

In Canada, consult local building and safety
codes or, in absence of such requirements,
follow CAN/CSA B149.
3.1.2 Ducted Combustion Air
The combustion air can be taken through the
wall, or through the roof. Bradford White offers
accessories to use with ducted air systems, as
shown in Table 3.
See Table 4 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 6).
Use ABS, PVC, CPVC, polypropylene, stainless
steel, or galvanized pipe for the combustion
air intake. (See Table 4) The intake must be
sized per Table 2. Route the intake to the boiler
as directly as possible. Seal all joints. Provide
adequate hangers. The unit must not support
the weight of the combustion air intake pipe.
The maximum equivalent pipe length allowed is
100 feet (30 m).
Each elbow is considered to be 5 feet (1.5m)
When using polypropylene or stainless steel
materials in horizontal duct congurations, a
single elbow must be installed on the end of the
air inlet to act as an outdoor terminal. In vertical
duct applications, two elbows must be installed
on the end of the inlet to act as a vent terminal.
When elbows are use as terminals, appropriate
screens must be installed to prevent blockage.
The elbow(s) required for termination are not
included in the kits sown in Table 3
The connection for the intake air pipe is on the
back panel.
In addition to air needed for combustion, air
shall also be supplied for ventilation, including
air required for comfort and proper working
conditions for personnel. Refer to the applicable
codes.
3.2 Venting
WARNING
Selection of improper vent materials for
installations that are installed in closets, or will be
operated in high ambient temperature levels, may
lead to property damage, personal injury, or death.
WARNING
Failure to use the appropriate vent material,
installation techniques, or glues and sealants
could lead to vent failure causing property
damage, personal injury or death.

Installation Standards
Material United States Canada
Stainless steel UL 1738 Venting must be ULC S636 certied for use as
venting material. The venting material class must
be chosen based upon the intended application
of the boiler, and must be installed according to
the maximum ue gas temperature and the vent
manufacturer’s instructions.

is considered to be 5 feet (1.5m). Bradford
White offers accessories to use with horizontal
and vertical exhaust vent systems, as shown in
Table 5
3.2.1 Common Venting
The MagnaTech can be common vented,
however, the common venting must be a
professionally designed and approved system.
MagnaTech units are never permitted to share a
vent with any Catagory 1 appliances.
3.2.3 Venting Requirements Unique to
Canada
MagnaTech boilers and water heaters are Vent
Category IV appliances. Per the requirements
of CAN/CSA-B149.1, only BH vent systems
can be connected to these units and such vent
systems, either ULC S636 certied stainless
steel or other ULC S636 certied BH vent
(eg. plastics) must be installed per the vent
manufacturer’s certied installation instructions.
It is the responsibility of the appropriately
licensed technician installing this MagnaTech to
use ULC S636 certied vent material consistent
with the requirements as described in the
Venting and Combustion Air section.
Class I venting systems are suitable for gas-red
appliances producing ue gas temperature of more
than 135°C, but not more than 245°C.
Class II venting systems are suitable for gas-red
appliances producing ue gas temperatures of 135°C
or less.
Class II venting systems are further classied into
four temperature ratings as follows:
A Up to and including 65°C / 149°F
B Up to and including 90°C / 194°F
C Up to and including 110°C / 230°F and
D Up to and including 135°C / 275°F
Flue Gas Sampling Port -
It is also the responsibility of the installer to
ensure that a ue gas sampling port is installed
in the vent system. This ue gas sampling port
must be installed near the ue connection of the
MagnaTech: within 2 feet of the ue connection.
There is no ue gas sampling port internal to
the MagnaTech, so one must be installed in the
vent system external to the MagnaTech. A ue
gas sampling port available as a component of
the ULC S636 certied vent system is preferred.
However, if one is not available with the certied
vent system, Bradford White suggests using a
tee with the branch connection sized to allow
for insertion of a ue gas analyzer probe. The
branch connection must be resealable with a
cap or other means to ensure the vent system
remains sealed. (See Figure 2)
Consideration must be given to the placement
and orientation of the ue gas sampling port to
ensure that condensate is free to ow back into
the MagnaTech and not collect anywhere in the
vent system - including in the ue gas sampling
port.
Exhaust Vent Terminal -
An exhaust vent terminal must be installed.
If an exhaust vent terminal is not available
with the certied vent system, Bradford White
suggests the use of a coupler tting from
the certied vent system into which the vent
terminal screen can be installed. Be sure to
install and terminate both vent and combustion
air pipes per the instructions in this section.

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 See Figure
5 and Figure 4 for proper spacing and
orientation.
3.3.2 Side Wall Combustion Air Terminal
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, 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 ( 2.1
m) 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
84”

12 inches (30 cm) above grade, but the
installer may determine it should be higher,
depending upon local conditions.
4. If the MagnaTech is side-wall vented to the
same wall, use Figure 4 to determine the
proper mounting locations.
5. Multiple vent kits should be installed such
that the horizontal distance between outlet
group and inlet group is 84” (213 cm).
(See Figure 5)
6. The vent outlet must be at least 12” above
the top of the air inlet, and must be at least
84” (213 cm) horizontally from the air inlet.
(See Figure 5).
3.3.3 Vertical Vent Terminal
When the unit is vented through the roof, the
vent must extend at least 3 feet (0.9 m) above
the point at which it penetrates the roof. It must
extend at least 2 feet (0.6 m) higher than any
portion of a building within a horizontal distance
of 10 feet (3.0 m), and high enough above the
roof line to prevent blockage from snow. The
vent terminal offered with the MagnaTech can be
used in both vertical and horizontal applications.
When the combustion air is taken from the roof,
the combustion air must terminate at least 12”
(30 cm) below the vent terminal.
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.
The opening on the end of the terminal must be
at least 12” (30 cm) 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” (30 cm) below
the vent terminal.
3.3.5 Installations in the Commonwealth
of Massachusetts
In Massachusetts the following items
are required if the side-wall exhaust vent
termination is less than seven (7) feet above
nished grade in the area of the venting,
including but not limited to decks and porches.

3.4 Common Vent Test
Note -This section does not describe a method
for common venting MagnaTech’s. It describes
what must be done when a unit is removed from
a common vent system. MagnaTech’s require
special vent systems and fans for common vent.
Contact the factory if you have questions about
common venting MagnaTech’s.
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 or other deciencies which could
cause an unsafe condition.
3. Insofar as is practical, close all building doors
and windows and all doors between the space
in which the appliances remaining connected
to the common venting system are located
and other spaces of the building. Turn on
any 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 ve 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 the 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 the
installation conforms with the National Fuel
Gas Code, ANSI Z223.1/NFPA 54 and/or
CAN/CSA B149.1, National Gas and Propane
Installation Code. When resizing any portion
of the common venting system, the common

WARNING
Do not use open ame to check for leaks. An
open ame could lead to explosion, which
could result in property damage, serious injury
or death.
Note - The MagnaTech appliance and all other
gas appliances sharing the gas supply line
must be ring at maximum capacity to properly
measure the inlet supply pressure. The pressure
can be measured at the supply pressure port
on the gas valve. Low gas pressure could be an
indication of an undersized gas meter, undersized
gas supply lines and/or an obstructed gas supply
line. MagnaTech units may be equipped with low
and high gas pressure switches that are integrally
vent limited. These types of devices do not
require venting to atmosphere.
Section 4
GAS SUPPLY AND PIPING
4.0 Gas Supply and Piping
Gas piping should be supported by suitable
hangers or oor stands, not the appliance.
Installers should refer to local building and
safety codes or, in the absence of such
requirements, follow the National Fuel Gas
Code, ANSI Z223.1 NFPA and/or CSA B149.1
installation codes.
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. MagnaTech appliances are normally
equipped to operate at elevations up to
2000 feet (610m).
However, the appliance 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. Table 8 and Table 9 offer some gas pipe
sizing information. Refer to the applicable
gas code for more detailed sizing
information.
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
