units unless the vent system meets this
requirement. Brute Elite units are never permitted
to share a vent with Category I appliances.
A condensate drain trap is built into Brute Elite.
Connect a 3/4" PVC pipe between the drain
connection and a floor drain (or condensate pump if a
floor drain is not accessible).
The condensate drain must be installed so as to
prevent accumulation of condensate. When a con-
densate pump is not used, the tubing must continuously
slope downward toward the drain with no spiraling.
Consult local codes for disposal method.
Caution
Condensate is mildly acidic (pH
5), and may harm
some floor 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.
3.2.1 Venting Requirements Unique to
Canada
Brute Elite 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
certified stainless steel or other ULC S636 certified BH
vent (eg. plastics) must be installed per the vent
manufacturer's certified installation instructions.
As a result, two items listed in the Unpacking
section (Figure 8) are
not included with Brute Elite
units for Canada (underlined):
A. exhaust vent terminal (not included)
B. air intake terminal
C. temperature/pressure gauge kit
D. circulator pump/wire harness (units with pump)
E. CPVC exhaust pipe section (80-500) (not incl.)
F. outdoor/system sensor kit
G. flow switch kit (399-850)
H. alternate size vent/terminal screens
J. exhaust vent adapter CPVC/ST ST (750-850)
It is the responsibility of the appropriately licensed
technician installing this Brute Elite unit to use ULC
S636 certified vent material consistent with the
requirements as described in the Venting and
Combustion Air section.
IMPORTANT! It is also the responsibility of the
installer to ensure that a flue gas sampling port is
installed in the vent system. This flue gas sampling port
must be installed near the flue connection of the Brute
Elite unit: within 2 feet of the flue connection. There is
no flue gas sampling port internal to the Brute Elite, so
one must be installed in the vent system external to the
Brute Elite unit. A flue gas sampling port available as a
component of the ULC S636 certified vent system is
preferred. However, if one is not available with the
certified vent system, Bradford White suggests using a
tee with the branch connection sized to allow for
insertion of a flue gas analyzer probe. The branch
connection must be resealable with a cap or other by
other means to ensure the vent system remains sealed
(Figure 11).
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 Elite 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 Elite
and shown in the Unpacking section of the Brute Elite
Installation & Operating Instructions, be installed. Be
sure to install and terminate both vent and combustion
air pipes per the Venting and Combustion Air section of
the Brute Elite instructions.
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:
