Fit pipe insulation over the incoming cold water line and the hot water line. Make sure that the insulation is against the top cover of the heater.

Fit T & P valve insulation over valve. Make sure that the insula- tion does not interfere with the lever of the T & P valve.

Secure all insulation using tape.

TEMPERATURE-PRESSURE RELIEF VALVE

Figure 5 shows the typical attachment of the water piping to the water heater. The water heater is equipped with 3/4“ NPT water connections.

NOTE: If using copper tubing, solder tubing to an adapter before attaching the adapter to the cold water inlet connection. Do not solder the cold water supply line directly to the cold water inlet. It will harm the dip tube and damage the tank.

T & P VALVE AND PIPE INSULATION (IF SUPPLIED)

Remove insulation for T & P valve and pipe connections from carton.

This heater is provided with a properly certified combination temperature - pressure relief valve by the manufacturer.

The valve is certified by a nationally recognized testing labora- tory that maintains periodic inspection of production of listed equipment of materials as meeting the requirements for Relief Valves for Hot Water Supply Systems, ANSI Z21.22 • CSA 4.4, and the code requirements of ASME.

If replaced, the valve must meet the requirements of local codes, but not less than a combination temperature and pressure relief valve certified as indicated in the above paragraph.

The valve must be marked with a maximum set pressure not to ex- ceed the marked hydrostatic working pressure of the water heater (150 psi = 1,035 kPa) and a discharge capacity not less than the water heater input rate as shown on the model rating plate.

For safe operation of the water heater, the relief valve must not be removed from its designated opening nor plugged.

The temperature-pressure relief valve must be installed directly into the fitting of the water heater designed for the relief valve. Position the valve downward and provide tubing so that any discharge will exit only within 6 in. (152mm) above, or at any

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.
