Page 4: Installation
General Information continued- IMPORTANT Before proceeding, please inspect the water heater and components for possible damage. DO NOT install any damaged components. If damage is evident then please contact the supplier where the water heater was purchased, or the manufacturer listed on the rating plate for replacement parts. - Page 5 Installation (Locating the Water Heater) continued- This water heater MUST be installed indoors out of the wind and weather. This water heater MUST NOT be installed in any location where gasoline or flammable vapors are likely to be present, unless the installation is such to eliminate the probable ignition of gasoline or flammable vapors.
- Page 6 Installation (Locating the Water Heater) continued- WARNING Liquefied petroleum gases/propane gases are heavier than air and will remain at floor level if there is a leak. Basements, crawl spaces, closets and areas below ground level will serve as pockets for accumulation of leaking gas.
- Page 7 Installation (Locating the Water Heater) continued- It is recommended that a minimum clearance of four (4) inches (10.2 cm) be provided on the side of the water heater for servicing and maintenance of the combination temperature and pressure relief valve. To comply with NSF requirements this water heater is to be: a) Sealed to the floor with sealant, in a smooth and easily cleanable way, or...

Page 8: Minimum Clearances
Minimum Clearances WARNING Failure to adhere to these installation and operating instructions may create a hazard to life and property and will nullify the warranty. This installation must allow access to the front of the water heater and adequate clearance must be provided for servicing and operating this water heater. -
Page 9: Venting
Venting WARNING The venting system must be installed properly following all local codes or in the absence of local codes, the latest edition of the National Fuel Gas Code (ANSI Z223.1- latest edition), or in Canada, The Natural Gas and Propane Installation Code (B149.1-00 latest edition). Failure to properly install the venting system could result in property damage, personal injury, or death. -

Page 12: Water Connections
Water Connections Note: BEFORE PROCEEDING WITH THE INSTALLATION, CLOSE THE MAIN WATER SUPPLY VALVE. After shutting off the main water supply, open a faucet to relieve the water line pressure to prevent any water from leaking out of the pipes while making the water connections to the water heater. - Page 13 Installation (Water Connections) continued- WARNING For protection against excessive temperatures and pressure, install temperature and pressure protective equipment required by local codes, but not less than a combination temperature and pressure relief valve certified by a nationally recognized testing laboratory that maintains periodic inspection of production of listed equipment or materials as meeting the requirements of the Standard for Relief Valves and Automatic Gas Shutoff Devices for Hot Water Supply...
- Page 14 Installation (Water Connections) continued- WARNING Hydrogen gas can be produced in an operating water heater that has not had water drawn from the tank for a long period of time (generally two weeks or more). Hydrogen gas is extremely flammable. To prevent the possibility of injury under these conditions, we recommend the hot water faucet to be open for several minutes at the kitchen sink before you use any electrical appliance, which is connected to the hot water system.

Page 15: Gas Connections
Gas Connections The gas supply lines must meet all requirements of the National Fuel Gas Code (ANSI Z223.1-Latest Edition), or in Canada CAN/CGA B149.1 Natural Gas Installation Code (Latest Edition) or CAN/CGA B149.2 Propane Installation Code (Latest Edition). The minimum permissible gas supply pressure for the purpose of input adjustment is one (1.0) inch (0.25 kPa) water column above the operating manifold pressure. - Page 16 Installation (Water Connections) continued- 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).

General Operation continued- DANGER Hotter water increases the risk of scald injury. Scalding may occur within five (5) ° seconds at a temperature setting of 140°F (60 C). To protect against hot water injury, install an ASSE approved mixing valve in the water system. This valve will reduce point of discharge temperature by mixing cold and hot water in branch water lines. -

Questions and answers
How do we lower or adjust water temperature on model #RG275H6N
To adjust the water temperature on the Bradford White model RG275H6N:
1. Locate the thermostat control on the gas control valve.
2. Turn the set point knob to the desired temperature setting.
Note: Be cautious when setting temperatures above 120°F (49°C), as water hotter than 140°F (60°C) can cause scalding within five seconds. To help prevent scald injuries, consider installing an ASSE-approved mixing valve.
