remains sealed. (See Figure 20)
Consideration must be given to the placement and orientation
of the flue gas sampling port to ensure that condensate is free
to flow back into the Brute unit and not collect anywhere in
the vent system - including in the flue gas sampling port.
An exhaust vent terminal must be installed. If an exhaust
vent terminal is not available with the certified vent system,
Bradford White suggests the use of a coupler fitting from the
certified vent system into which the vent terminal screen,
included with the Brute and shown in the Unpacking section,
be installed. Be sure to install and terminate both vent and
combustion air pipes per the Venting and Combustion Air
section of the Brute instructions.
3.4 Locating Vent and Combustion Air
Terminals
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 points
listed on the following page when installing the terminal.
1.
Figure 22 shows the requirements for mechanical vent
terminal clearances for the U.S. and Canada.
The Outdoor Brute must be installed at least 10 ft
(the vent pipe) from any door or window that can
be opened. The exhaust vent shall bot be under any
overhang or roof. Use only the vent components
included with the boiler.
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.
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.
Side Wall Combustion Air Terminal
The Bradford White side wall combustion air terminal, or
concentric terminal must be used when the heater takes air
from a side wall. (See page 16 ) Contact Bradford White for
AL29-4C termination fittings. Consider the following when
installing the terminal. (See Figure 22 through Figure 21.)
1.
Do not locate the air inlet terminal near a source of
corrosive chemical fumes (e.g., cleaning fluid, 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 the outlet group and the
inlet group is 36” (90cm). (Figure 23.)
6.
The vent outlet for models 199-285 must be no lower
than the center of the air inlet, and must be at least 12”
(30cm) away from the air inlet. Vent outlets for models
399-850 must be at least 12” above the top of the air
inlet, and must be at least 36” (90cm) horizontally from
the air inlet. (page 22.)
