ALVR42 Architectural Aluminum Louver

Facade

In many applications, architects and installers will choose to use facades over the front of Magic-Pak units. Often this is done to improve the appearance of a building. Properly constructed louver facades may also provide some degree of weather protection and sound deflection.

Louver facades can be designed by engineers and architects and inte- grated into the building construction by contractors in the field. However research and testing has shown that many designs may actually diminish the performance of the Magic-Pak units and in some cases even damage them.

For these reasons, Armstrong approved the ALVR42 architectural alumi- num louver facade kit. The instructions provided with the kit should serve as a general guide for installation of the kit. For guidelines on designing louver facades, refer to the Magic-Pak Application Manual (Armstrong P/N MPA-100).

The ALVR42 is designed to be integrated into the construction of the finish wall or secured directly to the finish wall. Therefore, actual installa- tion of the louvers will vary depending on the type of finish wall it is applied to.

The ALVR42 kit is available is many different colors to match finish walls. Color matching services are also available. For more information con- cerning color matching, please contact your supplier or Armstrong.

Assembly

The ALVR42 kit consists of two sections of louver fins. The top section is composed of fins angled approximately 30° upward while the bottom section consists of fins angled approximately 30° downward (see Figure 7-3). This design allows flue gases and condenser discharge air to be circulated away from the condenser inlet and burner compartment fresh air intake.

There is also a sealing gasket between the two louver sections to allow for separation of inlet and discharge air when the louver is secured directly to the front of the unit. When the louver is secured away from the unit, a separation bracket sealed to the unit and then to the louver kit must be field-fabricated and installed.

The ALVR42 louver is 45" tall to accommodate proper drainage of the unit and wall sleeve and proper discharge of condenser air and flue gases.

Installation

The ALVR42 is designed to be fastened to the finish wall, support wall or wall sleeve using field-supplied materials and techniques.

Whenever installing a louver facade of any type, special considerations must be made for proper drainage and air circulation. The drain holes of

the wall sleeve and the unit must never be obstructed.SRM -HW/HWC
