SEDIMENT TRAPS

 

FILLING THE WATER HEATER

A sediment trap shall be installed as close to the inlet of the water heater as practical at the time of water heater installation. The sediment trap shall be either a tee fitting with a capped nipple in the bottom outlet or other device recognized as an ef- fective sediment trap. If a tee fitting is used, it shall be installed in conformance with one of the methods of installation shown in Figures 8 and 9.

Contaminants in the gas lines may cause improper operation of the gas control valve that may result in fire or explosion. Before attaching the gas line be sure that all gas pipe is clean on the in- side. To trap any dirt or foreign material in the gas supply line, a drip leg (sometimes called a sediment trap) must be incorporat- ed in the piping. The drip leg must be readily accessible. Install in accordance with the “Gas Piping” section. Refer to the current edition of the National Fuel Gas Code ANSI Z223.1/NFPA 54.

Never use this water heater unless it is completely full of water. To prevent damage to the tank, the tank must be filled with water. Water must flow from the hot water faucet before turning “ON” gas to the water heater.

To fill the water heater with water:

1.Close the water heater drain valve by turning the handle to the right (clockwise). The drain valve is on the lower front of the water heater.

2.Open the cold water supply valve to the water heater. NOTE: The cold water supply valve must be left open when the water heater is in use.

3.To insure complete filling of the tank, allow air to exit by open- ing the nearest hot water faucet. Allow water to run until a constant flow is obtained. This will let air out of the water heater and the piping.

4.Check all water piping and connections for leaks. Repair as needed.

VENTING

NEVER OPERATE THE HEATER UNLESS IT IS VENTED TO THE OUTDOORS AND HAS ADEQUATE AIR SUPPLY TO AVOID RISKS OF IMPROPER OPERATION, FIRE, EXPLOSION OR ASPHYXIATION.

DO NOT OBSTRUCT THE FLOW OF COMBUSTION AND VENTILATING AIR. ADEQUATE AIR FOR COMBUSTION AND VENTILATION MUST BE PROVIDED FOR SAFE OPERATION.

HIGH ALTITUDE INSTALLATIONS

Installations above 7,700 ft. (2347 m) require replacement of the burner orifice in accordance with the National Fuel Gas Code ANSI Z223.1/NFPA 54. Failure to replace the orifice could result in improper and inefficient operation of the appliance, producing carbon monoxide gas in excess of safe limits, which could result in serious personal injury or death. Contact your gas supplier for any specific changes which may be required in your area.

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.
