GENERAL INFORMATION This gas-fired water heater’s design is certified by CSA International under the American National Standard Z21.10.1 - (latest edition) and CSA 4.1-M (latest edition). 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- IMPORTANT Before proceeding, please inspect the water heater and its 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.
Installation (Locating The Water Heater) continuedThe location of this water heater is of the utmost importance. Before installing this water heater read the Installation section of these instructions. After reading these Installation and Operating Instructions, select a location for the water heater where the floor is level and is easily accessible to gas and water supply lines. DO NOT locate the water heater where water lines could be subjected to freezing temperatures.
Installation (Locating The Water Heater) continued- 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. IF YOU SMELL GAS: • Do not try to light any appliance.
Installation (Locating The Water Heater) continued- The water heater must be located close enough to the outside wall to keep the venting distance within the maximum distance described in the vent kit’s installation instructions. Note: The direct vent-air intake terminal must be installed on a vertical wall. Read the instructions from the vent kit that was purchased with the water heater before locating the water heater.
OPTIONAL DIRECT VENT-AIR INTAKE TERMINAL GUARD WARNING The direct vent-air intake terminal is HOT while the water heater is in operation. Do not touch. Keep children, combustibles, gasoline and other liquids having flammable vapors away. It is recommended that a vent-air intake terminal guard be installed when the vent-air intake terminal is located where it can be touched accidentally, or accessed by children. (See Figure 2).
Installation continued- Figure 2 Figure 3 10
VENTING WARNING The vent-air intake system must be properly installed. Failure to properly install the vent-air intake system could result in property damage, personal injury or death. DO NOT install any damaged vent-air intake system components. Contact the manufacturer of the water heater for replacement parts. This is a Direct Vent Gas Water Heater where all air for combustion is obtained from the outside atmosphere and all flue gases are discharged to the outside atmosphere.

Venting continued1 In accordance with the current CAN/CGA-B149 Installation Codes. In accordance with the current ANSI Z223.1-(Latest edition)/NFPA 54 National Fuel Gas Code. † A vent must not terminate directly above a sidewalk or paved driveway that is located between two singlefamily dwellings and serves both dwellings. ‡ Permitted only if a veranda, porch, deck or balcony is fully open on a minimum of two sides beneath the floor.
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.
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 Systems, A
Water Connections continued- WARNING FAILURE TO INSTALL AND MAINTAIN A NEW, LISTED 3/4” X 3/4” TEMPERATURE AND PRESSURE RELIEF VALVE WILL RELEASE THE MANUFACTURER FROM ANY CLAIM, WHICH MIGHT RESULT FROM EXCESSIVE TEMPERATURES AND PRESSURES. If this water heater is installed in a closed water supply system, such as the one having a back-flow preventer in the cold water supply, provisions must be made to control thermal expansion.
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. See the rating plate and gas valve for the manifold pressure and gas type.
GENERAL OPERATION WARNING Water heaters are heat producing appliances. To avoid damage or injury, do not store materials against the water heater or vent-air intake system. Use proper care to avoid unnecessary contact (especially by children) with the water heater and vent-air intake system.
Lighting & Shutdown Instructions – White Rodgers and Robertshaw gas control.
Lighting & Shutdown Instructions Continued - Honeywell gas control.
THERMOSTAT ADJUSTMENT - White Rodgers gas control. 160°F Control 180°F Control Figure 5 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.
Thermostat Adjusting continued – Honeywell control.
Thermostat Adjusting 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. A licensed plumbing professional or local plumbing authority should be consulted.
MAINTENANCE WARNING Water heaters are heat producing appliances. To avoid damage or injury, do not store materials against the water heater or vent-air intake system. Use proper care to avoid unnecessary contact (especially by children) with the water heater and vent-air intake system.
Maintenance continued- 6. Annually remove the inner door and main burner assembly to clean orifices and related parts of any dirt or other foreign material. Inspect the burner ports for obstructions or debris and clean with a wire brush as needed. Wire brush and/or vacuum clean the combustion chamber as needed to remove scale deposits and debris. Inspect the inner door gasket for wear and tear and replace if necessary.
Maintenance continued- CAUTION FOR YOUR SAFETY, DO NOT ATTEMPT REPAIR OF COMBINATION GAS CONTROL, BURNERS OR GAS PIPING. REFER REPAIRS TO A QUALIFIED SERVICE TECHNICIAN. Contact your supplier or plumbing professional for replacement parts or contact the company at the address given on the rating plate of the water heater. Provide the part name, model and serial numbers of the water heater when ordering parts.
