appliances. If assistance is required in determining how a blocked vent safety system should be connected to a Bradford White product, please call Applications Engineering at the Rochester phone number listed on back cover of this manual.

Refer to the installation and operating instructions on all appliances to be common vented for instructions, warnings, restrictions and safety requirements. If safe operation of all appliances connected to a common vent cannot be assured, including prevention of spillage of flue gasses into living spaces, common venting should not be applied, and appliances should each be vented separately.

2.2.4 Category III Vent

When the Copper Brute II is vented with horizontal discharge, it must be installed per this installation manual and the venting system manufacturer’s installation instructions. The vent system must be sealed stainless steel, per Table 5.

Route the vent pipe to the heater as directly as possible. Seal all joints and provide adequate hangers as required in the venting system manufacturer’s Installation Instructions. Horizontal portions of the venting system must be supported to prevent sagging and may not have any low sections that could trap condensate. The unit must not support the weight of the vent pipe. Horizontal runs must slope downwards not less than ¼ inch per foot (2 cm/m) from the unit to the vent terminal. Reference Table 2 for the size of the Category III vent system. Up to three elbows can be used with 50 linear feet (15.2m) of pipe. Subtract 10 allowable linear feet (3.0m) for every additional elbow used.

WARNING

The outdoor vent terminal gets hot. Unit must be installed in such a way as to reduce the risk of burns from contact with the vent terminal.

2.3.1 Side Wall Vent Terminal

The appropriate Bradford White side wall vent hood must be used, and is listed in the installation and operation manual. The terminal provides a means of installing the vent piping through the building wall,

and 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:

1.Figure 3 shows the requirements for mechanical vent terminal clearances for the U.S. and Canada.

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, locations under windows or near doors should be avoided.

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 such surfaces or objects.

7.If the boiler or water heater uses ducted combustion air from an intake terminal located on the same wall, locate the vent terminal at least

3 feet (0.9m) horizontally from the combustion air terminal, and locate the vent terminal at least

1 foot (0.3m) above the combustion air terminal.

2.3.2Side Wall Combustion Air Terminal

The Bradford White side wall combustion air

terminal (listed in Table 2) must be used when the unit takes its combustion air through a duct from a side wall. 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 fluid, chlorinated compounds, etc.)

2.Locate the terminal so that it will not be subject to damage by accident or vandalism.

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 (30 cm) above grade, but the installer may determine it should be higher, depending upon local conditions.

4.If the Copper Brute II is side-wall vented to the same wall, locate the vent terminal at least 3 feet (0.9m) horizontally from the combustion air terminal, and locate the vent terminal at least 1 foot (0.3m) above the combustion air terminal (see Figure 3).
