GENERAL INFORMATION This gas-fired water heater is design certified by CSA International under the applicable American National Standard, Z21.10.1 or CSA 4.1-(as indicated on the rating plate), available from CSA International, 8501 East Pleasant Valley Road, Cleveland, OH U.S.A. 44131-5575. This water heater must be installed in accordance with local codes. In the absence of local codes, it must be installed in compliance with the National Fuel Gas Code (ANSI Z223.
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. This water heater has been manufactured for operation at altitudes from sea level to 2000 feet (610 m) (unless otherwise specified on the water heater rating plate).
INSTALLATION LOCATING THE WATER HEATER WARNING Water heaters are heat producing appliances. To avoid damage or injury there shall be no materials stored against the water heater or vent-air intake system and proper care shall be taken to avoid unnecessary contact (especially by children) with the water heater and vent-air intake components.
Installation (Locating the Water Heater) continued- Note: For California installation, this water heater must be braced, anchored, or strapped to avoid falling or moving during an earthquake. See instructions for correct installation procedures. Instructions may be obtained from DSA Headquarters Office, 1102 Q Street, Suite 5100, Sacramento, CA 95811. Water heater corrosion and component failure can be caused by the heating and breakdown of airborne chemical vapors.
Installation (Locating The Water Heater) continued- WARNING 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 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.
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. CAUTION Do not solder plumbing joints directly above the flue. Solder may fall down the flue and cause damage to combustion components. This installation shall allow access to the front of the water heater and adequate clearance shall be provided for servicing and operating this water heater.
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.
Venting continued- This water heater must be connected to a lined masonry chimney or venting system approved by local codes or ordinances. The vent connector used to attach the draft diverter outlet to the chimney or approved vent must be of the same diameter as the draft diverter outlet or larger. For proper venting in certain installations, a larger vent connector may be needed. Consult venting tables in ANSI standard (Z223.1-or latest edition), National Fuel Gas Code and CAN/CGA (B149.1 or B149.
Combustion Air Supply continued- Confined Spaces Confined spaces are spaces defined as having less than 50 feet³ (1.41 m³) of space per 1,000 BTU (.29kw) per hour of input. Unconfined Spaces In unconfined spaces in buildings, infiltration may be adequate to provide air for combustion, ventilation and dilution of flue gases. However, in buildings of tight construction (for example, weather stripping, heavily insulated, caulked, vapor barrier, etc.
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. 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.
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 Su
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.
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 1 inch (0.25 kPa) water column above the operating manifold pressure. See the rating plate and gas valve for the manifold pressure and gas type.
GENERAL OPERATION Water heaters are heat producing appliances. To avoid damage or injury there shall be no materials stored against the water heater or vent-air intake system, and proper care shall be taken to avoid unnecessary contact (especially by children) with the water heater and vent-air intake system.

THERMOSTAT ADJUSTMENT - White Rodgers gas control. 160°F Control 180°F Control Figure 2 Figure 3 The thermostat dial is set to its lowest temperature setting when shipped from the factory. Remember that lower temperature settings are more energy efficient. Adjust the temperature by turning the thermostat dial. It is suggested that the starting point setting not be greater than the “ ” or “ ” mark on the thermostat dial (approximately 120°F [48.9°C]) as indicated above.

Remember that lower temperature settings are more energy efficient. Adjust the temperature by turning the thermostat dial. It is suggested that the starting point setting not be greater than the “HOT” mark on the thermostat dial (approximately 120°F [48.
Burner flame check continued- These models are equipped with self-adjusting air mixture and do not have an adjustable air shutter. At periodic intervals, a visual check of the main burner and pilot flames should be made to determine if they are burning properly. The main burner flame should light smoothly from the pilot. The burner flame should be soft and undefined. After five minutes of burner operation the burner face should be glowing orange and emitting an orange flame.
Maintenance continuedThe following maintenance should be performed by a qualified service technician at the minimum periodic intervals suggested below. In some installations, the maintenance interval may be more frequent depending on the amount of use and the operating conditions of the water heater. Regular inspection and maintenance of the water heater and vent-air intake system will help to insure safe and reliable operation. 1. Annually check the operation of the thermostat. 2.
Maintenance continued- WARNING THIS WATER MAY BE HOT. 7. Monthly drain off a gallon of water to remove silt and sediment. 8. If the combination temperature and pressure relief valve on the appliance discharges periodically, this may be due to thermal expansion in a closed water supply system. Contact the water supplier or local plumbing inspector on how to correct this situation. Do not plug the combination temperature and pressure relief valve outlet. 9.
