INSULATION BLANKETS

Insulation blankets available to the general public for external use on gas water heaters are not necessary with this product. The purpose of an insulation blanket is to reduce the standby heat loss encountered with storage tank water heaters. Your Water heater meets or exceeds the National Appliance Energy Conser- vation Act standards with respect to insulation and standby loss requirements, making an insulation blanket unnecessary.

Should you choose to apply an insulation blanket to this heater, you should follow these instructions (See Figure 1 for identifica- tion of components mentioned below). Failure to follow these instructions can restrict the air flow required for proper combus- tion, resulting in fire, asphyxiation, serious personal injury or death.

•Do not cover the outer door, thermostat or temperature & pressure relief valve.

•Do not cover the instruction manual. Keep it on the side of the water heater or nearby for future reference.

•Do obtain new warning and instruction labels from the manu- facturer for placement on the blanket directly over the exist- ing labels.

VENTILATION FOR APPLIANCES LOCATED IN CONFINED SPACES

FIGURE 3

Confined Space is a space whose volume is less than 50 cubic feet per 1,000 Btu per hour (4.8 cm per kW) of the aggregate input rating of all appliances installed in that space.

VENT TERMINATION

Before installing water heater determine placement of vent ter- mination.

Make certain to observe vent location limitation, see Figures 3, 4 & 11.

Minimum clearances between the water heater and combustible and noncombustible construction are: 0 in. (0mm) from sides, 0 in. (0mm) from back, 4 in. (102mm) from front of jacket to closet door and 20 in. (508mm) from top of jacket to combustible and noncombustible material. Minimum vent clearance: 1 in. (25mm)*. Provide 3 ft. (915mm) front clear- ance for servicing and adequate clearance between the jacket top & ceiling for servicing the flue area, see Figure 4.

*Where the wall is combustible and the wall thickness is over 14 in. (356mm), 1 in. (25mm) clearance to combustible materials around the vent terminal is needed. The first 14 in. (356mm) is zero clearance.

Make certain the vent locations comply with the National Fuel Gas Code ANSI Z223.1/NFPA 54 and/or local codes. There is some important information shown in Figure 11.

For a second or more direct vent unit, the distance between vent terminals must be a minimum of 12 in. (305mm).

GDV, GDVT specifications

A.O. Smith is a well-known name in the water heating industry, and its GDVT and GDV series of water heaters exemplify the company's commitment to quality, efficiency, and innovation. These models are designed to provide reliable hot water solutions for both residential and commercial needs, seamlessly integrating advanced technology and user-friendly features.

One of the main features of the GDVT and GDV series is their high energy efficiency ratings. These water heaters utilize advanced insulation and energy-saving technologies, allowing them to achieve impressive efficiency levels. The GDVT series, for instance, can achieve an Energy Factor (EF) rating of up to 0.96, making it an environmentally friendly choice that can significantly reduce energy bills. This high level of efficiency is a result of thoughtful engineering, including a highly insulated tank that minimizes heat loss.

Another standout characteristic of the GDVT and GDV series is their compact design. These models are built to fit into tight spaces, making them ideal for homes or businesses with limited installation areas. Despite their compact size, they maintain a large storage capacity, ensuring that users have access to consistent hot water. The GDVT series is particularly known for its vertical design, which allows for easy installation in smaller utility rooms or closets.

The GDV models feature a robust digital display that provides real-time information about the water heater's operation. Users can easily monitor the unit’s performance and make adjustments as needed. Additionally, these models come equipped with advanced safety features, including a built-in safety shut-off system and over-temperature protection, ensuring safe and reliable operation.

Both the GDVT and GDV series utilize A.O. Smith's innovative HydroJet® technology, which minimizes sediment buildup within the tank. This technology involves the strategic placement of an internal dip tube that maximizes water circulation, helping to extend the life of the water heater and maintain optimal performance over the years.

In summary, the A.O. Smith GDVT and GDV series water heaters are an excellent choice for those seeking a balance of efficiency, compact design, advanced technology, and enhanced safety. With their impressive energy ratings, user-friendly features, and cutting-edge technologies, these units are tailored to meet the demands of modern residential and commercial water heating solutions, ensuring a consistent supply of hot water while minimizing environmental impact.
