LOCATING THE NEW WATER HEATER FACTS TO CONSIDER ABOUT THE LOCATION • Carefully choose an indoor location for the new water heater, because the placement is a very important consideration for the safety of the occupants in the building and for the most economical use of the appliance. This water heater is not for use in manufactured (mobile) homes or outdoor installation. Sensors mounted in the drain pan that turn off the water supply to the entire home when water is detected in the drain pan.
Confined Space is a space whose volume is less than 50 cubic feet per 1,000 Btu per hour (4.8 cm per kW) of the aggregate input rating of all appliances installed in that space. VENT TERMINATION Before installing water heater determine placement of vent termination. Make certain to observe vent location limitation, see Figures 3, 4 & 12. INSULATION BLANKETS Minimum clearances between the water heater and combustible and noncombustible construction are: 0 in. (0mm) from sides, 0 in. (0mm) from back, 4 in.
INSTALLING THE NEW WATER HEATER REQUIRED ABILITY INSTALLATION OR SERVICE OF THIS WATER HEATER REQUIRES ABILITY EQUIVALENT TO THAT OF A LICENSED TRADESMAN IN THE FIELD INVOLVED. PLUMBING, AIR SUPPLY, VENTING AND GAS SUPPLY ARE REQUIRED. INSPECT SHIPMENT This water heater shall not be connected to any heating systems or component(s) used with a non-potable water heating appliance. There may be hidden damage caused in transit. Check to be certain all parts of the venting system, as listed below, are present.
FIGURE 6 HOT WATER OUTLET COLD WATER INTLET Fit pipe insulation over the incoming cold water line and the hot water line. Make sure that the insulation is against the top cover of the heater. Fit T & P valve insulation over valve. Make sure that the insulation does not interfere with the lever of the T & P valve.

distance below the structural floor. Be certain that no contact is made with any live electrical part. The discharge opening must not be blocked or reduced in size under any circumstances. Excessive length, over 30 ft. (9.14m), or use of more than four elbows can cause restriction and reduce the discharge capacity of the valve, see Figures 5 or 10. 4.
minimum inlet gas pressure shown on the rating plate is that which will permit firing at rated input. All gas piping must comply with local codes and ordinances or with the National Fuel Gas Code ANSI Z223.1/NFPA 54 whichever applies. Copper and brass tubing and fittings (except tin lined copper tubing) shall not be used. If the gas control valve is subjected to pressures exceeding 1/2 psi (3.5 kPa), the damage to the gas control valve could result in a fire or explosion from leaking gas.
FILLING THE WATER HEATER SEDIMENT TRAPS Never use this water heater unless it is completely full of water. To prevent damage to the tank, the tank must be filled with water. Water must flow from the hot water faucet before turning “ON” gas to the water heater. A sediment trap shall be installed as close to the inlet of the water heater as practical at the time of water heater installation.
COMBUSTION AIR AND VENTILATION When determining the installation location for a direct vent water heater, snow accumulation and drifting should be considered in areas where applicable. VENT TERMINAL CLEARANCES The vent system must terminate so that proper clearances are maintained as cited in local codes or the current edition of the National Fuel Gas Code ANSI Z223.
LOCATING CLEARANCE HOLE FOR VENT Cut a clearance hole, approximately 7 in. (178mm) in diameter, through the exterior wall for the vent assembly. The recommended height is 68 in. (1.72m) for 40 gal. models and 76 in. (1.93m) for 50 gal., 50 gal. Hi-Input and 75 gal. models, as measured from the hole center to bottom of water heater. The maximum height recommended is 80 in. (2.03m) or in compliance with Figure 16. Where the wall is combustible and the wall thickness is over 14 in. (356mm), 1 in.

TEMPERATURE REGULATION TEMPERATURE REGULATION Time to Produce 2nd & 3rd Degree Burns on Adult Skin Temperature Setting HOT WATER CAN SCALD: Water heaters are intended to produce hot water. Water heated to a temperature that will satisfy space heating, clothes washing, dish washing, and other sanitizing needs can scald and permanently injure you upon contact. Some people are more likely to be permanently injured by hot water than others.
FOR YOUR INFORMATION EXTERNAL DAMAGE THERMAL EXPANSION Do not operate the water heater until it has been fully checked out by a qualified technician, if the water heater: • • • Has been exposed to fire or damage. Displays evidence of sooting. Produces steam or unusually hot water. If the water heater has been flooded it must be replaced.
lines. Contact the local water heater supplier or service agency for further information concerning an Anode Replacement Kit and this chlorination treatment. If the smelly water persists after the anode replacement and chlorination treatment, we can only suggest that chlorination or aeration of the water supply be considered to eliminate the water problem. Do not remove the anode leaving the tank unprotected. By doing so, all warranty on the water heater tank is voided.
MAINTENANCE FOR YOUR SAFETY AND SATISFACTORY OPERATION, IT IS RECOMMENDED THAT THIS HEATER BE CHECKED ONCE A YEAR BY A COMPETENT SERVICE PERSON. a flooded water heater. Do not attempt to repair the unit! It must be replaced! At least once a year a visual inspection should be made of the main burner and the pilot assembly for proper flame characteristics. This can be done by removing the Outer Door and viewing the main burner operation through the Viewport on the Inner Door, see Figure 1.
DRAINING If the heater is to be shut off and exposed to freezing temperatures, it must be drained. Water, if left in the tank and allowed to freeze, will damage the heater. • Turn off the gas and cold water inlet valve to the heater, Figure 1. • Open a nearby hot water faucet and the heater drain valve. • BE CAREFUL TO GRASP THE DRAIN VALVE HANDLE SO THAT THE HAND IS NOT EXPOSED TO HOT WATER. IF DESIRED, A HOSE MAY BE CONNECTED TO THE DRAIN VALVE TO CARRY THE WATER AWAY. The water CAN BE HOT.
Before removing the anode: 1) the tank water should be cool, 2) the cold water shut off valve must be closed, and 3) water pressure must be relieved by opening a nearby faucet. DRAIN VALVE WASHER REPLACEMENT (See Figure 29) 1. Turn “OFF” gas supply to water heater. 2. Follow “Draining” instructions. 3. Turning counterclockwise ( ), remove the hex cap below the screw handle. 4. Remove the washer and put the new one in place. 5.
LEAKAGE CHECKPOINTS SERVICE If a condition persists or you are uncertain about the operation of the water heater contact a service agency. Use this guide to check a “Leaking” water heater. Many suspected “Leakers” are not leaking tanks. Often the source of the water can be found and corrected. If you are not thoroughly familiar with gas codes, your water heater, and safety practices, contact your gas supplier or qualified installer to check the water heater. Read this manual first.
