GENERAL INFORMATION This gas-fired water heater’s design is certified by CSA International under the American National Standard Z21.10.1 - (as indicated on the rating plate) and CSA 4.1-M - (as indicated on the rating plate). EF ER EN C E O N LY This water heater must be installed in accordance with local codes or, in the absence of local codes, the National Fuel Gas Code, ANSI Z223.1-Latest Edition) and/or in Canada CAN/CGA B149 Installation Codes (Latest Editions).
General Information continued- N LY A sacrificial anode is used to extend tank life. The removal of this anode, for any reason, will nullify the warranty. In areas where water is unusually active, an odor may occur at the hot water faucet due to a reaction between the sacrificial anode and the impurities in the water. If this should happen, an alternative anode may be purchased from the supplier that installed this water heater. This will minimize the odor while protecting the tank.
O N LY Water heater corrosion and component failure can be caused by the heating and breakdown of airborne chemical vapors. Examples of some typical compounds that are potentially corrosive are: spray can propellants, cleaning solvents, refrigerator and air conditioning refrigerants, swimming pool chemicals, calcium and sodium chloride, waxes and process chemicals. These materials are corrosive at very low concentration levels with little or no odor to reveal their presence.
Installation (Locating The Water Heater) continued- WARNING EF ER EN C E O N LY DO NOT ATTEMPT TO LIGHT ANY GAS APPLIANCE IF YOU ARE NOT CERTAIN OF THE FOLLOWING: • Liquefied petroleum gases/propane gas and natural gas have an odorant added by the gas supplier that aids in the detection of the gas. • Most people recognize this odor as a “sulfur” or “rotten egg” smell. • Other conditions, such as “odorant fade” can cause the odorant to diminish in intensity, or ”fade”, and not be as readily detectable.
Installation (Minimum Clearances) continued- 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. IN TE R N ET VE R SI O N FO R R EF ER EN C E O N LY 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.
Venting N LY This venting section is divided into two parts. Part I will cover venting specifications for 48 Gal - 65,000 BTU (181.7 L - 19.1 kW/Hr), 65 Gal -65,000 BTU (246.1 L - 19.1 kW/Hr), and 75 Gal - 76,000 BTU (283.9 L - 22.3 kW/Hr) models. Part II will cover venting specifications for 40 Gal -40,000 BTU (151.4 L - 11.7 kW/Hr) and 48 gal - 40,000 BTU (181.7 L - 11.7 kW/Hr) models. Refer to the rating plate located on the water heater for correct model identification.
(E) The vent terminal must not terminate above a paved sidewalk or a paved driveway which is located on private adjacent property. Venting (Part I) continued- Venting System Condensation Condensate formation does not occur in all installations of power vented heaters, but should be protected against on installations where condensation can form in the venting system.
In order to prevent condensate from draining back into the blower (vertical or horizontal runs), a drain tee and condensate trap can be installed in the horizontal vent as close as practical to the blower vent connection (see Figure 1). The condensate disposal tube should be installed to drain any accumulated condensate away from the water heater and to a suitable drain. The drain tee and condensate hose are not available from Bradford White, but should be available through your local distributor.

Combustion Air Supply WARNING Liquefied petroleum gases/propane gas 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. Before lighting, smell all around the appliance area for gas. Be sure to smell next to the floor. EF ER EN C E O N LY IF YOU SMELL GAS: • Do not try to light any appliance.
Installation (Combustion Air Supply) continued- O N LY All Air From Inside the Building: The confined space must be provided with two permanent openings communicating directly with an additional room(s) of sufficient volume so that the combined volume of all spaces meets the criteria for an unconfined space. The total input of all gas utilization equipment installed in the combined space must be considered in making this determination.
N LY 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. After the pressure has been relieved, close the faucet. The COLD water inlet and HOT water outlet are identified on the top of the water heater.
WARNING EF ER EN C E O N LY 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 Systems, ANS Z21
Installation (Water Connections) continued- WARNING O N LY 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.
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).
