Gas Connections

The gas supply lines must meet all requirements of the National Fuel Gas Code ANSI Z223.1-(Latest Edition) and/or in Canada CAN/CGA B149 Installation Codes - (Latest Editions).

The minimum permissible gas supply pressure for the purpose of input adjustment is 1.5” water column (.37 kPa) above the operating manifold pressure for natural gas and 1.0” (.25 kPa) water column for L.P. gas. See the rating plate and combination gas control for the manifold pressure and gas type. The maximum permissible gas supply pressure is 14.0” water column (3.5 kPa) for natural gas and liquefied petroleum gases/propane gas.

1.Connect this water heater only to the type of gas (Natural or Propane gas) as shown on the rating plate. Use clean 1/2 inch (1.3 cm) black iron pipe. (Dirt and scale from the pipe can enter the combination control and cause it to malfunction). The inlet gas line must have a minimum length of 3” (7.6 cm) drip leg (sediment trap) installed as close to the water heater’s combination gas control as possible. A ground joint union must be installed in the gas supply line feeding the water heater to permit servicing of the water heater. Compounds used on the threaded joints of the gas piping must be resistant to the action of liquefied petroleum gases/propane gas.

2.This water heater and its gas connection must be leak tested before placing the water heater in operation. Check for gas leaks with a soap and water solution and a brush or a commercial leak detector fluid. NEVER USE A

MATCH OR OPEN FLAME FOR TESTING!

CAUTION

The water heater and individual shutoff valve must be disconnected from the gas supply piping system during any pressure testing of the system at test pressures in excess of 1/2 psi (3.5 kPa). The water heater must be isolated from the gas supply piping system by closing its manual shutoff valve during any pressure testing of the gas supply system at test pressures equal to or less than 1/2 psi (3.5 kPa). The supply line must be capped when not connected to the water heater.

3.While checking for leaks care must be taken to prevent solution from contacting the electrical connections at the control. If electrical connections at the control become wet, they must be thoroughly dried before attempting to operate the water heater.

Homeowners can now enjoy the benefits of a high-efficiency water heater without the constraints imposed by venting through walls or roofs.

Efficiency is at the forefront of the Powered Direct Vent Series, boasting an Energy Factor (EF) that meets or exceeds industry standards. These units utilize a combination of advanced insulation and heat exchange technology to reduce standby heat loss. This means that less energy is wasted, leading to lower utility bills and a reduced carbon footprint. The series also features options designed for a range of fuel types, including natural gas and propane, catering to the diverse needs of different households.

Durability is another key characteristic of the Bradford-White Powered Direct Vent Series. Each unit is constructed with high-quality materials, including a robust tank with a glass-lined interior to resist corrosion. This ensures longevity and reliable performance over the lifespan of the system. Additionally, the units are equipped with advanced safety features, such as a high-temperature limit switch and a flame arrestor, which provide peace of mind for homeowners.

The user-friendly controls and diagnostics on these models make them easy to monitor and maintain. With built-in LED indicators and self-diagnostics, homeowners and service technicians can quickly assess the unit's performance and troubleshoot any issues that may arise. This ensures that hot water is always available when needed, enhancing overall convenience.

In summary, the Bradford-White Powered Direct Vent Series combines advanced technology, high efficiency, and durable construction to deliver exceptional water heating solutions. With features tailored for safety and convenience, these units are an excellent choice for any home seeking a reliable and energy-efficient hot water solution.
