TYPICAL INST ALLA TION INSTALLA ALLATION MIXING VALVE USAGE FIGURE 2. This appliance has been design certified as complying with ANSI Z21.10.3 latest edition for water heaters and is considered suitable for: HOTTER WATER CAN SCALD: Water heaters are intended to produce hot water. Water heated to a temperature which will satisfy space heating, clothes washing, dish washing, and other sanitizing needs can scald and permanently injure you upon contact.
LOCA TING THE NEW W ATER HEA TER OCATING WA 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.
Minimum clearances between the water heater and combustible construction are 0 inch at the sides and rear, 4” (102 mm) at the front, and 6” (153 mm) from the vent pipe. Clearance from the top of the jacket is 12” (305 mm) on most models. Note that a lesser dimension may be allowed on some models, refer to the label attached adjacent to the gas control valve on the water heater, see Figure 3. INSULATION BLANKETS FIGURE 3. FIGURE 3.
Btu per hour (5.5 cm2/kW) of total input rating of all equipment in the enclosure, see Figure 7. A. ALL AIR FROM INSIDE BUILDINGS: (See Figures 4 and 5) The confined space shall 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 shall be considered in making this determination.
INST ALLING THE NEW W ATER HEA TER INSTALLING WA HEATER As water is heated, it expands (thermal expansion) and closed systems do not allow for the expansion of heated water. WATER PIPING The water within the water heater tank expands as it is heated and increases the pressure of the water system. If the relieving point of the water heater’s temperature-pressure relief valve is reached, the valve will relieve the excess pressure.
Figure 9 shows the typical attachment of the water piping to the water heater. The water heater is equipped with 1” NPT threaded nipple (75 gallon models) or 1.25” NPT threaded nipple (100 gallon models) water connections. NOTE: If using copper tubing, solder tubing to an adapter before attaching the adapter to the cold water inlet connection. Do not solder the cold water supply line directly to the cold water inlet. It will harm the dip tube and damage the tank.
Vent dampers must bear evidence of certification as complying with the current edition of the American National Standard ANSI Z21.66 CGA 6.14 (covering electrically and mechanically actuated vent dampers). Before installation of any vent damper, consult the local gas utility for further information. FILLING THE WATER HEATER To insure proper venting of this gas-fired water heater, the correct vent pipe diameter must be utilized.
Make sure the gas supplied is the same type listed on the model rating plate. The inlet gas pressure must not exceed 14 inch water column (2.6 kPa) for natural and propane (L.P.) gas. The minimum inlet gas pressure shown on the rating plate is that which will permit firing at rated input. If the gas control valve is subjected to pressures exceeding 1/2 pound per square inch (3.5 kPa), the damage to the gas control valve could result in a fire or explosion from leaking gas. FIGURE 12.
FIGURE 14. GAS PIPING WITH ALL BLACK IRON PIPE TO GAS CONTROL. SEDIMENT TRAPS Use pipe joint compound or teflon tape marked as being resistant to the action of petroleum [Propane (L.P.)] gases. A sediment trap shall be installed as close to the inlet of the water heater as practical at the time of water heater installation. The sediment trap shall be either a tee fitting with a capped nipple in the bottom outlet or other device recognized as an effective sediment trap.
FOR YOUR SAFETY READ BEFORE LIGHTING WARNING: If you do not follow these instructions exactly, a fire or explosion may result causing property damage, personal injury or loss of life. BEFORE LIGHTING: ENTIRE SYSTEM MUST BE FILLED WITH WATER AND AIR PURGED AT FAUCETS. A. B. This appliance has a pilot which must be lighted by hand. When lighting the pilot, follow these instructions exactly. BEFORE LIGHTING: smell all around the appliance area for gas.

TEMPERA TURE REGULA TION TEMPERATURE REGULATION Never allow small children to use a hot water tap, or to draw their own bath water. Never leave a child or handicapped person unattended in a bathtub or shower. Short repeated heating cycles caused by small hot water uses can cause temperatures at the point of use to exceed the thermostat setting by up to 30°F (16.7°C). If you experience this type of use you should consider using lower temperature settings to reduce scald hazards.
Because of the suddenness and amount of water, condensation water may be diagnosed as a “tank leak”. After the water in the tank warms up (about 1-2 hours), the condition should disappear. OPERATIONAL CONDITIONS Do not assume the water heater is leaking until there has been enough time for the water in the tank to warm up. In each water heater there is installed at least one anode rod (see parts section) for corrosion protection of the tank.
PERIODIC MAINTENANCE You should check for sooting. Soot is not normal and will impair proper combustion. VENTING SYSTEM INSPECTION Soot build-up indicates a problem that requires correction before further use. Turn “OFF” gas to water heater and leave off until repairs are made, because failure to correct the cause of the sooting can result in a fire causing death, serious injury, or property damage. NATURAL PROPANE At least once a year a visual inspection should be made of the venting system.
INSTALLED IN SUITABLE AREA: To insure sufficient ventilation and combustion air supply, proper clearances from the water heater must be maintained. See “Locating the New Water Heater” section. Combustible materials such as clothing, cleaning materials, or flammable liquids, etc. must not be placed against or adjacent to the water heater which can cause a fire. If the temperature-pressure relief valve on the appliance weeps or discharges periodically, this may be due to thermal expansion.
SERVICE Use the ”Leakage Checkpoints” 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. Before calling for repair service, read the "Start Up Conditions" and "Operational Conditions" found in the "For Your Information" section of this manual. Read this manual first.
