INSTALLING THE NEW WATER HEATER

REQUIRED ABILITY

INSTALLATION OR SERVICE OF THIS WATER HEATER REQUIRES ABILITY EQUIVALENT TO THAT OF A LICENSED TRADESMAN IN THE FIELD INVOLVED. PLUMBING, AIR SUPPLY, VENTING AND GAS SUPPLY ARE REQUIRED.

INSPECT SHIPMENT

There may be hidden damage caused in transit. Check to be certain all parts of the venting system, as listed below, are present. CAUTION!!! IF THERE ARE ANY DAMAGED

PARTS, DO NOT INSTALL THIS WATER HEATER. REPORT ANY SHORTAGE TO YOUR DISTRIBUTOR OR DAMAGE TO YOUR CARRIER.

GENERAL

The installation must conform to these instructions and the lo- cal code authority having jurisdiction. In the absence of local codes, the installation must comply with the current editions of the National Fuel Gas Code ANSI Z223.1/NFPA 54. The code is available from the Canadian Standards Association, 8501 East Pleasant Valley Road, Cleveland, OH 44131.

WATER PIPING

HOTTER WATER CAN SCALD:

Water heaters are intended to produce hot water. Water heated to a temperature which will satisfy space heating, clothes wash- ing, dish washing, cleaning and other sanitizing needs can scald and permanently injure you upon contact. Some people are more likely to be permanently injured by hot water than others. These include the elderly, children, the infirm, or physically/men- tally handicapped. If anyone using hot water in your home fits into one of these groups or if there is a local code or state law requiring a certain temperature water at the hot water tap, then you must take special precautions. In addition to using the low- est possible temperature setting that satisfies your hot water needs, a means such as a *mixing valve, should be used at the hot water taps used by these people or at the water heater, see Figure 2. Valves for reducing point of use temperature by mixing cold and hot water are also available:

Consult a Qualified Installer or Service Agency. Follow man- ufacturer’s instructions for installation of the valves. Before changing the factory setting on the thermostat, read the “Tem- perature Regulation” section in this manual.

This water heater shall not be connected to any heating systems or component(s) used with a non-potable water heating appli- ance.

All piping components connected to this unit for space heating applications shall be suitable for use with potable water.

Toxic chemicals, such as those used for boiler treatment shall not be introduced into this system.

When the system requires water for space heating at tem- peratures higher than required for domestic water purposes, a tempering valve must be installed. Please refer to Figure 2 for suggested piping arrangement.

Water supply systems may, because of such events as high line pressure, frequent cut-offs, the effects of water hammer among others, have installed devices such as pressure reducing valves, check valves, back flow preventers, etc. to control these types of problems. When these devices are not equipped with an internal by-pass, and no other measures are taken, the devices cause the water system to be closed. As water is heated, it expands (thermal expansion) and closed systems do not allow for the expansion of heated water.

The water within the water heater tank expands as it is heated and increases the pressure of the water system. If the relieving point of the water heater’s temperature-pressure relief valve is reached, the valve will relieve the excess pressure. The temperature-pressure relief valve is not intended for the constant relief of thermal expansion. This is an unacceptable condition and must be corrected.

It is recommended that any devices installed which could create a closed system have a by-pass and/or the system have an ex- pansion tank to relieve the pressure built by thermal expansion in the water system. Expansion tanks are available for ordering through a local plumbing contractor. Contact the local water supplier and/or a service agency for assistance in controlling these situations.

NOTE: To protect against untimely corrosion of hot and cold water fittings, it is strongly recommended that di-electric unions or couplings be installed on this water heater when connected to copper pipe.

All gas piping must comply with local codes and ordinances or with the National Fuel Gas Code ANSI Z223.1/NFPA 54 which- ever applies. Copper and brass tubing and fittings (except tin lined copper tubing) shall not be used.

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.
