2.B Venting
2.B.1 Vent Categories
'epending upon desired Copper Brute ll venting,
it may be considered a Category I or a Category III
applianceIn general, a vertical vent system will
be a Category I systemHowever, in rare instances,
a Copper Brute ll’s vertical vent system may be
considered Category IIIIn the 86, the 1ational )uel
*as Code (A16I =1-/atest (dition), or in Canada
the C6A B11 (latest edition), de¿nes a Category
I vent system, and includes rules and tables to size
these vent systemsIf the Copper Brute ll’s vertical
vent system does not satisfy the criteria for Category I
venting, it must be vented as a Category III system
All Copper Brute ll vent systems which discharge
horizontally (without the use of a power venter) are
considered Category III vent systems
2.B.2 Category I Vent
When vented as a category I appliance, the
vent system must conform to the 1ational )uel *as
Code (A16I =1-/atest (dition) in the 86, or
in Canada, to C6A B11 (latest edition)The vent
system must be sized and installed for a Category I
)an-Assisted Appliance
If chimney height is greater than feet, or
if multiple units are vented into the same vertical
vent, a barometric damper must be installed on each
appliance, such that the Àue draft does not e[ceed
(negative) 1wc
If using a power venter for any type of Category
I venting, the draft should be set between (negative)
1 and 1 wc

COPPER BRUTE II (500 - 2000) INSTALLATION AND OPERATING INSTRUCTIONS
2.B.3 Common Venting Systems
Copper Brute ll units are Category I fan-assisted
when vented vertically and adhering to all applicable
codesCopper Brute ll units are not allowed to be
vented into a common horizontal Cat III vent system
(horizontal discharge or other con¿guration for Cat
III), 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 engineerWhen
common venting Copper Brute ll fan-assisted unit
with other appliances through one shared vertical duct
called a ³common vent´, special care must be taken by
the installer to ensure safe operationIn 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.

It is for this reason that, in addition to
following proper vent sizing, construction and safety
requirements from the 1ational )uel *as Code,
A16I =1 or in Canada, from C6A B11 as
well as all applicable local codes, it is required that
installers provide some means to prevent operation
with a blocked common ventIt is suggested that a
blocked vent safety system be employed such that if
the switch from one appliance trips due to e[cessive
stack spill or backpressure indicating a blocked vent
condition, that all appliances attached to the vent be
locked out and prevented from operating1ote that
the Copper Brute ll is equipped with a blocked vent
safety (pressure) switch, as shippedHowever, this
safety switch has only been designed and tested to be
effective in installations where the Copper Brute ll
is vented separately and 12T common vented with
other appliancesAs an additional precaution, it is
recommended that a Carbon Mono[ide (C2) alarm be
installed in all enclosed spaces containing combustion
appliancesIf assistance is required in determining
how a blocked vent safety system should be connected
to a Bradford White product, please call Applications
(ngineering at the 5ochester phone number listed on
back cover of this manual
5efer to the installation and operating
instructions on all appliances to be common vented
for instructions, warnings, restrictions and safety
requirementsIf safe operation of all appliances
connected to a common vent cannot be assured,
including prevention of spillage of Àue gasses into
living spaces, common venting should not be applied,
and appliances should each be vented separately

Table 6. Vent Terminals for Outdoor Units.
2.E Vent Terminals for Outdoor Units
For outdoor applications, the vent and
combustion air openings must be covered with proper
terminals to prevent rain, snow and other objects from
falling into the Copper Brute ll.
If local codes allow, outdoor installations may
use 1' of appropriately sized galvanized single wall
or B-Vent and a rain cap for exhaust vent termination
in the default con¿guration (venting out of the top).
An appropriately sized galvanized 90° ell, positioned
with the opening facing down, may be used on the
combustion air inlet in the default con¿guration on
the back of the unit. Note that some local codes may
require a higher vertical vent height, extending above
any perimeter fencing, etc. In installations where
the appearance of the vent is objectionable, the low
pro¿le vent terminals in Table may be used.
3art numbers for the low pro¿le terminals
to cover the vent and combustion air openings are
shown in Table .

SECTION 3 Gas Supply and Piping
3.A Gas Supply and Piping
Gas piping should be supported by suitable
hangers or Àoor stands, not by the appliance.
The Copper Brute ll’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. Copper
Brute ll appliances are equipped to operate at
elevations up to 10,000 feet (00m). Copper
Brute ll appliances may be adjusted to operate
properly at altitudes above 00 feet (see
6(CTI2N 8 on page ) and the input will be
reduced if the heating value of the gas supply is
below sea level values.
. The maximum inlet gas pressure must not
exceed 1 w.c. (.kPa). The minimum inlet gas
pressure is w.c. (1.kPa).
. Refer to Table , size supply.
4. Run gas supply line in accordance with all
applicable codes.
. /ocate and install manual shutoff valves in
accordance with state and local requirements.
. A sediment trap must be provided upstream of
the gas controls.
. 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 P6IG (.4kpa).
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 P6IG (.4kpa).
10. The appliance and its gas connection must be
leak tested before placing it in operation.
11. Purge all air from gas lines.

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.

A hydronic heating (closed loop) application
re-circulates the same Àuid in the piping system. As a
result, no new minerals or oxygen is introduced into
the system. To ensure a proper operating temperature
leading to long boiler life, a Àow rate has been
established based on the Àuid 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 headloss through the heater, plus 0
feet (9.1m) of full-sized piping (same size as boiler
outlet) and a normal number of ¿ttings.
Table 8 speci¿es water Àow rates for boilers,
which will enable the user to size a pump. The
headloss shown is for the heater only, and the user
will need to add the headloss of the system piping to
properly size the pump.
The minimum inlet water temperature for the
Copper Brute ll is 10°F (49°C) to avoid condensing
on the copper coils.

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 1clearance
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
Àow check in the system supply loop. Minimum ¿ll
pressure must be 1psig (8.kPa). Install shutoff
valves where required by code.

Table 8 shows a relationship between water Àow
through the boiler and the temperature difference (rise)
between the inlet and outlet of the boiler. This table
will enable the user to test the boiler for proper water
Àow. 6ince the boiler has a mixing system that sends
a portion of the hot water from the boiler outlet to the
boiler inlet, the water Àow coming out of the mixing
system will vary, depending on the return water
temperature.

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 0and the anti freeze contains an
anti foamant. When a 00 mixture is used, increase
the water Àow requirements by 1, and increase the
headloss requirements by 0.
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, andor 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 Àooding conditions.
