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.

A.exhaust vent terminal (not included) 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.

3.3Locating 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:
