lation 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 1 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.

2.3Locating Vent & Combustion Air Terminals

2.3.1 Side Wall Vent Terminal

The appropriate 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 4 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. When possible, locations under windows or near doors should be avoided.

5.Locate the vent terminal so that it cannot be blocked by snow. The National Fuel gas code requires that it be at a minimum of 12" above grade. In a location that has the possibility of snow accumulation, it is critical the installer places the vent at least 12" higher than the maximum potential snow line. Seek local municipalities and their codes for appropriate installation techniques.

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.

2.3.2 Side Wall Combustion Air Terminal

The side wall combustion air terminal (see 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 a minimum of 12" above grade. Depending on local conditions, the installer should ensure that it remains at least 12" above the maximum potential snow line. Seek local municipalities and their codes for appropriate installation techniques.

WARNING: It is critical that the combustion air intake and the vent terminals remain at least 12" above the maximum potential snow line. If either the vent terminal or the air terminal is blocked by snow, there may be potential for the unit to produce excess carbon monoxide and or recirculate flue gasses into the building/dwelling. Personal injury or DEATH may occur. Natural snowfall, drifting, and banking should all be taken into account when locating the terminals in a potential snow environment.

4.If the Brute Deluxe 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 4).

2.3.3 Vertical Vent Terminal

When the unit is vented through the roof, the vent must extend at least 3 feet (0.9m) above the point at which it penetrates the roof. It must extend at least 2 feet (0.6m) higher than any portion of a building within a horizontal distance of 10 feet (3.0m), and high enough above the roof line to prevent blockage from snow. When the combustion air is taken from the roof, the combustion air must terminate at least 12" (30cm) below the vent terminal (see Figure 3). Seek local municipalities and their codes for appropriate installation techniques.
