COMBUSTION AIR & VENTILATION

WARNING

Carbon Monoxide Warning

Water heater must be vented to outdoors.

Vent must be installed by a qualified technician using the installation instructions.

Examples of a qualified technican include: gas technicians, authorized gas company personel, and authorized service persons.

Failure to so do can result in death or carbon monoxide poisoning.

IMPORTANT: Air for combustion and ventilation must not come from a corrosive atmosphere. Any failure due to corrosive elements in the atmosphere is excluded from warranty coverage.

The following types of installation (not limited to the following) will require outdoor air for combustion due to chemical exposure and may reduce but not eliminate the presence of corrosive chemicals in the air:

beauty shops

photo processing labs

buildings with indoor pools

water heaters installed in laundry, hobby, or craft rooms

water heaters installed near chemical storage areas

Combustion air must be free of acid-forming chemicals such as sulfur, fluorine, and chlorine. These elements are found in aerosol sprays, detergents, bleaches, cleaning solvents, air fresheners, paint, and varnish removers, refrigerants, and many other commercial and household products. When burned, vapors from these products form highly corrosive acid compounds. These products should not be stored or used near the water heater or air inlet.

Combustion and ventilation air requirements are determined by the location of the water heater. The water heater may be located in either an open (unconfined) area or in a confined area or small enclosure such as a closet or small room. Confined spaces are areas with less than 50 cubic feet for each 1,000 BTUH of the total input for all gas-using appliances.

Unconfined Space

A water heater in an unconfined space uses indoor air for combustion and requires at least 50 cubic feet for each 1,000 BTUH of the total input for all gas appliances. The table below shows a few examples of the minimum square footage (area) required for various BTUH inputs.

IMPORTANT:

The area must be open and be able to provide the proper air requirements to the water heater. Areas that are being used for storage or contain large objects may not be suitable for water heater installation.

Water heaters installed in open spaces in buildings with un- usually tight construction may still require outdoor air to func- tion properly. In this situation, outside air openings should be sized the same as for a confined space.

Modern home construction usually requires supplying out- side air into the water heater area.

Confined Space

For the correct and proper operation of this water heater, ample air must be supplied for the combustion, ventilation, and dilution of flue gases. Small enclosures and confined areas must have two permanent openings so that sufficient fresh air can be drawn from outside of the enclosure. One opening shall be within 12 inches of the top and one within 12 inches of the bottom of the enclosure as shown in Figure 13.

The size of each opening (free area) is determined by the total BTUH input of all gas utilization equipment (i.e., water heaters, furnaces, clothes dryers, etc.) and the method by which the air is provided. The BTUH input can be found on the water heater rating plate. Additional air can be provided by two methods:

1.All air from inside the building.

2.All air from outdoors.

Kenmore 153.33262 manual Combustion AIR & Ventilation, Unconfined Space, Confined Space, Square, Feet with With 8’ Ceiling

153.33262, 153.33264 specifications

The Kenmore 153.33262 and 153.33264 are highly versatile and efficient portable air conditioners designed to provide optimal cooling solutions for indoor spaces. These models stand out in their class due to their advanced features, technologies, and user-friendly characteristics, making them suitable for a variety of environments, from small apartments to large rooms.

One of the primary features of both the Kenmore 153.33262 and 153.33264 is their high cooling capacity. With powerful BTUs, they can effectively cool spaces up to a specified square footage. This capability ensures that users can maintain a comfortable indoor climate even during the hottest summer months. Their energy efficiency is another notable aspect, allowing homeowners to enjoy cooler air without incurring exorbitant energy bills.

The two models are equipped with various modes of operation, including cooling, fan, and dehumidifying modes. This multifunctionality allows users to customize their comfort based on prevailing weather conditions. For instance, the dehumidifying mode effectively reduces excess moisture in the air, creating a more comfortable environment, particularly in humid regions.

Both air conditioners come with a user-friendly digital interface that features an easy-to-read LED display. The interface allows for straightforward adjustments to the temperature, fan speed, and operating modes. Furthermore, remote control functionality enhances convenience, enabling users to change settings from across the room.

In terms of technology, these models incorporate a self-evaporating system that minimizes the need for manual water drainage. This feature is particularly advantageous for users who prefer low-maintenance options. Additionally, both units feature a washable air filter, designed to capture dust and allergens, improving air quality and ensuring that the units operate efficiently.

Portability is another significant characteristic of the Kenmore 153.33262 and 153.33264. Built-in caster wheels and side handles allow for easy movement from room to room, making them ideal for temporary cooling needs.
