CAUTION indicates a potentially hazardous situation which, if not avoided, may result in minor or moderate injury. CAUTION used without the safety alert symbol indicates a potentially hazardous situation which, if not avoided, could result in property damage. Important Instructions Do not use this appliance if any part has been under water. Immediately call a qualified service technician. Water heaters subjected to flood conditions or any time the gas controls, main burner or pilot have been submerged in water require replacement of the entire water heater. Hydrogen gas can be produced in a hot water system that has not been used for a long period of time (generally two weeks or more). Hydrogen gas is extremely flammable and can ignite when exposed to a spark or flame. To prevent the possibility of injury under these conditions, we recommend the hot water faucet be opened for several minutes at the kitchen sink before using any electrical appliance which is connected to the hot water system. If hydrogen is present, there will probably be an unusual sound such as air escaping through the faucet as water begins to flow. Do not smoke or have any open flame near the faucet at the time it is open. The California Safe Drinking Water and Toxic Enforcement Act requires the Governor of California to publish a list of substances known to the State of California to cause cancer, birth defects, or other reproductive harm, and requires businesses to warn of potential exposure to such substances. : This product contains a chemical known to the State of California to cause cancer, birth defects, or other reproductive harm. This appliance can cause low-level exposure to some of the substances included in the Act.

Storage of or use of gasoline or other flammable vapors or liquids in the vicinity of this or any other appliance can result in serious injury or death. Read and follow water heater warnings and instructions. Location Requirements Carbon Monoxide Poisoning Hazard Do not install in a mobile home. Doing so can result in death or carbon monoxide poisoning. Do not use or store flammable products such as gasoline, solvents, or adhesives in the same room or area near the water heater. If such flammables must be used, all gas burning appliances in the vicinity must be shut off and their pilot lights extinguished. Open the doors and windows for ventilation while flammable substances are in use. If flammable liquids or vapors have spilled or leaked in the area of the water heater, leave the area immediately and call the fire department from a neighbor s home. Do not attempt to clean the spill until all ignition sources have been extinguished. Fire or Explosion Hazard Read instruction manual before installing, using or servicing water heater. Improper use may result in fire or explosion. Maintain required clearances to combustibles. Keep combustibles such as boxes, magazines, clothes, etc. away from the water heater area. Site Location Select a location near the center of the water piping system. The water heater must be installed indoors and in a vertical position on a level surface. Consider the exhaust vent system piping and combustion air supply requirements when selecting the water heater location. The venting system must be able to run from the water heater to the termination with a minimal length and number of elbows. The venting system must comply with the requirements set forth in the venting section of this manual. Locate the water heater near the existing gas piping. If installing a new gas line, locate the water heater to minimize the pipe length and elbows. NOTE: This water heater must be installed according to all local and state codes or, in the absence of local and state codes, the National Fuel Gas Code, ANSI Z223.1(NFPA 54)-current edition. 4 CAUTION - PROPERTY DAMAGE HAZARD The water heater should be located in an area where leakage of the tank or connections will not result in damage to the area adjacent to the water heater or to lower floors of the structure. Due to the normal corrosive action of the water, the tank will eventually leak after an extended period of time. Also any external plumbing leak, including those from improper installation, may cause early failure of the tank due to corrosion if not repaired. If the owner/ operator is uncomfortable with making the repair a qualified person should be contacted. A suitable metal drain pan should be installed under the water heater as shown below, to help protect the property from damage which may occur from condensate formation or leaks in the piping connections or tank. The pan must limit the water level to a maximum depth of 1-3/4 and be two inches wider than the heater and piped to an adequate drain. NOTE: The pan must not restrict combustion air flow. Locate the water heater near a suitable indoor drain. Outside drains are subject to freezing temperatures which can obstruct the drain line. The piping should be at least 3/4 ID and pitched for proper drainage. 1-3/4 max. At least 2 greater than the water heater and the inlet air pipe.. Pipe to an adequate drain The water heater should be located in an area not subject to freezing temperatures. Water heaters located in unconditioned spaces (i.e., attics, basements, etc.) may require insulation of the water piping and drain piping to protect against freezing. The drain and controls must be easily accessible for operation and service. Maintain proper clearances as specified on the data plate. Do not locate the water heater near an air-moving device. The operation of air-moving devices such as exhaust fans, ventilation systems, clothes dryers, fireplaces, etc., can affect the proper operation of the water heater. Special attention must be given to conditions these devices may create. Flow reversal of flue gases may cause an increase of carbon monoxide inside of the dwelling. Clearances and Accessibility FIGURE 1 Minimum Clearance Locations Back Top View Top to ceiling Sides Sides Front 24 min. for service Vent NOTE: Minimum clearances from combustible materials are stated on the data plate adjacent to the gas control valve/thermostat of the water heater. The water heater is certified for installation on a combustible floor. IMPORTANT: If installing over carpeting, the carpeting must be protected by a metal or wood panel beneath the water heater. The protective panel must extend beyond the full width and depth of the water heater by at least 3 inches (76.2mm) in any direction or if in a alcove or closet installation, the entire floor must be covered by the panel. Fire Hazard For continued protection against the risk of fire: Do not install water heater on carpeted floor. Do not operate water heater if flood damaged. Figure 1 may be used as a reference guide to locate the specific clearance locations. A minimum of 24 inches of front clearance and 4 inches on each side should be provided for inspection and service. State of California NOTE: The water heater must be braced, anchored, or strapped to avoid moving during an earthquake. Contact local utilities for code requirements in your area or call and request instructions. 5 Gas Supply Figure 2 Gas Piping Manual gas shut-off valve Gas Requirements Read the data plate to be sure the water heater is made for the type of gas you will be using in your home. This information will be found on the data plate located near the gas control valve/thermostat. If the information does not agree with the type of gas available, do not install or light. Call your dealer. NOTE: An odorant is added by the gas supplier to the gas used by this water heater. This odorant may fade over an extended period of time. Do not depend upon this odorant as an indication of leaking gas. Gas Piping The gas piping must be installed according to all local and state codes or, in the absence of local and state codes, the National Fuel Gas Code, ANSI Z223.1(NFPA 54)-current edition. Tables 1 and 2 on the following page provide a sizing reference for commonly used gas pipe materials. Consult the National Fuel Gas Code for the recommended gas pipe size of other materials. Refer to Figure 2 NOTE: When installing gas piping, apply approved pipe joint compound. 1. Install a readily accessible manual shut-off valve in the gas supply line as recommended by the local utility. Know the location of this valve and how to turn off the gas to this unit. 2. Install a drip leg (if not already incorporated as part of the water heater) as shown. The drip leg must be no less than three inches long for the accumulation of dirt, foreign material, and water droplets. 3. Install a ground joint union between the gas control valve/thermostat and the manual shut-off valve. This is to allow easy removal of the gas control valve/thermostat. 4. Turn the gas supply on and check for leaks. Test all connections by brushing on an approved noncorrosive leak-detection solution. Bubbles will show a leak. Correct any leak found. 6 Explosion Hazard Use a new CSA approved gas supply line. Install a shut-off valve. Do not connect a natural gas water heater to an L.P. gas supply. Do not connect an L.P. gas water heater to a natural gas supply. Failure to follow these instructions can result in death, explosion, or carbon monoxide poisoning. Install a readily accessible manual shut-off valve in the gas supply line as recommended by the local utility. Gas Pressure IMPORTANT: The gas supply pressure must not exceed the maximum supply pressure as stated on the water heater s data plate. The minimum supply pressure is for the purpose of input adjustment. Gas Pressure Testing IMPORTANT: This water heater and its gas connection must be leak tested before placing the appliance in operation. If the code requires the gas lines to be tested at a pressure exceeding 14 W.C., the water heater and its manual shut-off valve must be disconnected from the gas supply piping system and the line capped. If the gas lines are to be tested at a pressure less than 14 W.C., the water heater must be isolated from the gas supply piping system by closing its manual shut-off valve. U.L. recognized fuel gas and carbon monoxide (CO) detectors are recommended in all applications and should be installed using the manufacturer s instructions and local codes, rules, or regulations. NOTE: Air may be present in the gas lines and could prevent the burner from lighting on initial start-up. The gas lines should be purged of air by a qualified person after installation of the gas piping system. L.P. Gas Only Explosion Hazard Have a qualified person make sure L.P. gas pressure does not exceed 13 water column. Examples of a qualified person include: licensed plumbers, authorized gas company personnel, and authorized service personnel. Failure to do so can result in death, explosion, or fire. Combustion Air Supply and Ventilation Carbon Monoxide Warning Follow all the local and state codes or, in the absence of local and state codes, the National Fuel Gas Code, ANSI Z223.1 (NFPA 54)- latest edition to properly install vent system. Failure to do so can result in death, explosion, or carbon monoxide poisoning. Combustion Air Supply This water heater takes its combustion air either from the installation area or from air ducted to the unit from the outside and all combustion products are discharged to the outdoors. IMPORTANT: Air for combustion and ventilation must not come from a corrosive atmosphere. Any failure due to corrosive elements in the atmosphere is excluded from warranty coverage. The following types of installation (not limited to the following) will require outdoor air for combustion due to chemical exposure and may reduce but not eliminate the presence of corrosive chemicals in the air: beauty shops photo processing labs buildings with indoor pools water heaters installed in laundry, hobby, or craft rooms water heaters installed near chemical storage areas Combustion air must be free of acid-forming chemicals such as sulfur, fluorine, and chlorine. These elements are found in aerosol sprays, detergents, bleaches, cleaning solvents, air fresheners, paint, and varnish removers, refrigerants, and many other commercial and household products. When burned, vapors from these products form highly corrosive acid compounds. These products should not be stored or used near the water heater or air inlet. Combustion and ventilation air requirements are determined by the location of the water heater. The water heater may be located in either an open (unconfined) area or in a confined area or small enclosure such as a closet or small room. Confined spaces are areas with less than 50 cubic feet for each 1,000 BTUH of the total input for all gas-using appliances. 7 Fire and Explosion Hazard Combustion air is drawn through the bi-directional air vent above the water heater. Do not store gasoline or other flammable substances above this water heater. Storage of gasoline or other flammable substances above this water heater can result in serious injury or death. Unconfined Space A water heater in an unconfined space uses indoor air for combustion and requires at least 50 cubic feet for each 1,000 BTUH of the total input for all gas appliances. The table below shows a few examples of the minimum square footage (area) required for various BTUH inputs. Table 3 BTUH Input Min. Sq. Feet with 8 Ceiling Typical Room with 8 Ceiling 30, x 21 45, x 20 60, x 25 75, x 31 90, x , x , x , x 30 IMPORTANT: The area must be open and be able to provide the proper air requirements to the water heater. Areas that are being used for storage or contain large objects may not be suitable for water heater installation. Water heaters installed in open spaces in buildings with unusually tight construction may still require outdoor air to function properly. In this situation, outside air openings should be sized the same as for a confined space. Modern home construction usually requires supplying outside air into the water heater area. Confined Space For the correct and proper operation of this water heater, ample air must be supplied for the combustion, ventilation, and dilution of flue gases. Small enclosures and confined areas must have two permanent openings so that sufficient fresh air can be drawn from outside of the enclosure. One opening shall be within 12 inches of the top and one within 12 inches of the bottom of the enclosure as shown in Figure 3. The size of each opening (free area) is determined by the total BTUH input of all gas utilization equipment (i.e., water 8 heaters, furnaces, clothes dryers, etc.) and the method by which the air is provided. The BTUH input can be found on the water heater data plate. Additional air can be provided by two methods: 1. All air from inside the building. 2. All air from outdoors. Figure 3 Opening Locations Confined Spaces Permanent openings to the outside or additional rooms within the building 12 Max. All Air from Inside the Building When additional air is to be provided to the confined area from additional room(s) within the building, the total volume of the room(s) must be of sufficient size to properly provide the necessary amount of fresh air to the water heater and other gas utilization equipment in the area.
