TYPICAL INSTALLATION MIXING VALVE USAGE FIGURE 2. This appliance has been design certified as complying with American National Standard/CSA Standard for water heaters and is considered suitable for: 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. Some people are more likely to be permanently injured by hot water than others.
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. FIGURE 3.
and 12" (30.5 cm) from the top. (Standard clearance.) If clearances stated on the heater differ from standard clearances, install water heater according to clearances stated on the heater. chlorine based chemicals, refrigerants, etc.) in addition to being highly flammable in many cases, will also react to form corrosive hydrochloric acid when exposed to the combustion products of the water heater. The results can be hazardous, and also cause product failure.
Chemical vapor corrosion of the flue, blower assembly and vent system may occur if air for combustion contains certain chemical vapors. Spray can propellants, cleaning solvents, refrigerator and air conditioner refrigerants, swimming pool chemicals, calcium and sodium chloride, waxes, bleach and process chemicals are typical compounds which are potentially corrosive. A.
INSTALLING THE NEW WATER HEATER WATER PIPING THERMAL EXPANSION As water is heated, it expands (thermal expansion). In a closed system the volume of water will grow. As the volume of water grows there will be a corresponding increase in water pressure due to thermal expansion. Thermal expansion can cause premature tank failure (leakage). This type of failure is not covered under the limited warranty.
Figure 10 shows the typical attachment of the water piping to the water heater. The water heater is equipped with 3/4 inch NPT 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. T & P Valve and Pipe Insulation (if supplied) Remove insulation for T & P valve and pipe connections from carton.
When installed at elevations above 7,700 feet (2,347 meters), input rating should be reduced at the rate of 4 percent for each 1,000 feet (305 meters) above sea level which requires replacement of the burner orifice in accordance with National Fuel Gas Code ANSI Z223.1/ NFPA 54. Contact your local gas supplier for further information.
SEDIMENT TRAPS To fill the water heater with water: 1. Close the water heater drain valve by turning the handle to the right (clockwise). The drain valve is on the lower front of the water heater. 2. Open the cold water supply valve to the water heater. NOTE: The cold water supply valve must be left open when the water heater is in use. 3. To insure complete filling of the tank, allow air to exit by opening the nearest hot water faucet. Allow water to run until a constant flow is obtained.
VENT CONNECTIONS TO BLOWER ASSEMBLY VENTING AND INSTALLATION Figure 15 shows the optimal placement of the 2" to 3" or 3" to 4" reducer; however, the vent can be reduced at any point in the vent system as long as the maximum and minimum vent length requirements are met. Plan the layout of the vent system from the vent termination to the water heater considering all of the 90° and 45° elbows plus the number of feet of pipe that would be needed to install the total vent system.
The unit may be vented horizontally through a wall or vertically through the roof. Pipe runs must be adequately supported along both vertical and horizontal runs as follows: condensate in the vent piping. If this occurs, then adequate means of draining and disposing of the condensate needs to be made by the installer. • For Schedule 40, 2" PVC, ABS, Coex Cellular Core vent pipe: Every 3 feet (0.9 m).
For 4" Venting, the maximum equivalent feet of pipe allowed is 160 feet (48.8 m). This does not include the Vent Termination (supplied locally) for the water heater. For the 4" venting, one 90° elbow is approximately equal to 8 feet (2.4 m). One 45° elbow is approximately equal to 4 feet (1.2 m). It is recommended that at least 2 feet (0.6 m) of spacing be used in between all 45° elbows and all 90°elbows.
FIGURE 16. This unit can vent through 2", 3" or 4" nonmetallic pipe and fittings. VERTICAL VENT TERMINATION RESTRICTIONS The vent pipe installation can be started from either the blower discharge or the termination wall. Keep in mind the total vent system (pipe and elbows) when installing the vent system, see VENTING AND INSTALLATION, pages 15 - 17. 1. Minimum of twelve 12" (30.5 cm) above the roof or twelve 12" (30.5 cm) above the anticipated snow level.
VENT PIPE PREPARATION PRIMER It is recommended that Tetrahydrofuran (THF) be used to prepare the surfaces of pipe and fittings for solvent welding. Do not use water, rags, gasoline or any other substitutes for cleaning PVC or CPVC surfaces. A chemical cleaner such as MEK may be used. 1. INITIAL PREPARATION A. Make sure the solvent cement you are planning to use is designed for the specific application you are attempting. B.
B. Deburring Use a knife, plastic pipe deburring tool, or file to remove burrs from the end of small diameter pipe. Be sure to remove all burrs from around the inside as well as the outside of the pipe. A slight chamfer (bevel) of about 10°-15° should be added to the end to permit easier insertion of the pipe into the end of the fitting. Failure to chamfer the edge of the pipe may remove cement from the fitting socket, causing the joint to leak. STEP E F.
TEMPERATURE REGULATION Due to the nature of the typical gas water heater, the water temperature in certain situations may vary up to 30°F (16.7°C) higher or lower at the point of use such as, bathtubs, showers, sink, etc. control has a tamper resistant feature for changing the temperature setting. To change the temperature setting follow these instructions: 1.
FOR YOUR INFORMATION START UP CONDITIONS STRANGE SOUNDS Possible noises due to expansion and contraction of some metal parts during periods of heat-up and cool-down do not necessarily represent harmful or dangerous conditions. CONDENSATE Whenever the water heater is filled with cold water, some condensate will form while the burner is on. A water heater may appear to be leaking when in fact the water is condensate.
PERIODIC MAINTENANCE VENTING SYSTEM INSPECTION proper combustion. A visual inspection of the main burner and HSI igniter assembly should also be done at least once a year, see Figure 20. 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. FIGURE 20.
If after manually operating the valve, it fails to completely reset and continues to release water, immediately close the cold water inlet to the water heater, follow the draining instructions, and replace the temperature-pressure relief valve with a new one. 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.
SERVICE 8. Follow the lighting instructions in the “Lighting” section to restart the water heater. 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.
