*If the horizontal distance is less than 30 in. (760mm), the restricter plate must be installed (see Figure 22).

The vent tube and terminal are assembled by the manufacturer as shown in Figure 18. There are springs fastened inside the corrugated tube. When the vent tubes are pulled to a required length, the distances between the springs will still be equally spaced.

Insert the 6 in. (52mm) tube through the clearance hole from exterior wall then secure the vent terminal to the exterior wall with 4 screw anchors (not included) appropriate for the type of wall construction. Caulk the junction of the vent terminal base plate and the exterior wall with exterior type sealant (not included).

1.Pull the 3-1/8 in. (80mm) corrugated tube towards the water heater and leave some length over the water heater’s center for bending.

2.Pull the 6 in. (152mm) corrugated tube toward the water heater and leave it 1 in. (25mm) shorter than 3-1/8 in. (80mm) tube.

3.Make sure there are two springs evenly spaced at the bend in the tube.

4.Use metal hangers to keep venting level or with a slope upward from the heater to terminal.

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.
