GENERAL INFORMATION This electric water heater’s design is certified by Underwriters Laboratories (UL) and listed in accordance with UL 174. cUL listed in accordance with Canadian National Standard C22.2, No. 110. Water heaters with a capacity of 19 gallons through 119 gallons are evaluated by UL in accordance with Part 280.707(d) (1) of HUD Mobile Home Construction and Safety Standards for Energy Efficiency.
General Information continuedA sacrificial anode(s) is used to extend tank life. Removal of any anode, except for inspection and/or replacement, will nullify the warranty. In areas where water is unusually active, an odor may occur at the hot water faucet due to a reaction between the sacrificial anode and impurities in the water. If this should happen, an alternative anode(s) may be purchased from the supplier that installed this water heater. This will minimize the odor while protecting the tank.
Locating the Water Heater continued- Some models are not equipped with a drain valve. For those models, install a drain tee in the cold-water inlet as close as practical to the water heater. Water heater corrosion and component failure can be caused by the heating and breakdown of airborne chemical vapors.
Locating the Water Heater continued- Note: Per Section 507.2 Seismic Provisions of the 2021 Uniform Plumbing Code (UPC). Water heaters shall be anchored or strapped to resist horizontal displacement due to earthquake motion. Strapping shall be at points within the upper one-third and lower one-third of its vertical dimensions. At the lower point, a distance of not less than 4 inches shall be maintained from the controls with the strapping.
Water Connections continuedAfter installation of the water lines, open the main water supply valve and fill the water heater. While the water heater is filling, open several hot water faucets to allow air to escape from the water system. When a steady stream of water flows through the faucets, close them and check all water connections for possible leaks. NEVER OPERATE THE WATER HEATER WITHOUT FIRST BEING CERTAIN IT IS FILLED WITH WATER.
Water Connections continued- WARNING Hydrogen gas can be produced in a hot water system served by this water heater that has not been used for a long period of time (generally two weeks or more). Hydrogen gas is extremely flammable. To reduce the risk of injury under these conditions, it is recommended that the hot water faucet be opened for several minutes at the kitchen sink before using any electrical appliance connected to the hot water system.
Water Connections continued- Upright Models (See Figures 1A & 1B) The hot and cold-water connections are identified on the top of the water heater (See figure 1A). For bottom inlet models, the cold-water inlet is located on the side of the drain valve (see figure 1B). Connect the hot and cold-water lines to the installed nipples using unions. Install a listed temperature-pressure relief valve in the opening on the side of the water heater.
Water Connections continued- INSTALLATION INSTRUCTIONS FOR INLET/OUTLET PIPE INSULATION & TEMPERATURE/PRESSURE RELIEF VALVE INSULATION 1. If included, install 2 ft. pipe insulation over both cold and hot outlet pipes. 2. If included, install temperature & pressure relief valve insulation over temperature & pressure relief valve. Note: The water heater may only have one T&P location.
Water Connections continued- Lowboy Models (See Figures 2A & 2B) The hot and cold-water connections are identified on the top of the water heater (See figure 2A). For bottom inlet models, the cold-water inlet is located on the side of the drain valve (see figure 2B). Connect the hot and cold-water lines to the installed nipples using unions. Install a listed temperature-pressure relief valve in the opening on the side of the water heater.
Water Connections continued- Utility Models (See Figure 3) All utility models are supplied with inlet and outlet nipples located in a plastic bag attached to the water heater. The hot and cold-water locations are identified on the side of the water heater. Apply appropriate amount of thread sealant to the provided nipples and install nipples into the side of the tank. For 20 gallon utility models, install the supplied anode/nipple combination at the HOT outlet location.
Electrical Connections Before any electrical connections are made, be sure that the water heater is full of water and that the manual shut-off valve in the coldwater supply line is open. Check the rating plate and wiring diagram before proceeding. This electric water heater was built and wired in accordance with the UL testing approvals requirements.
GENERAL OPERATION Before closing the switch to allow electric current to flow to the water heater, make certain that the water heater is full of water and that the cold-water inlet valve is open. Complete failure of the heating element(s) will result if they are not totally immersed in water at all times. Failure of the element(s) due to dry-firing is not covered by warranty. When the switch is closed, the operation of this electric water heater is automatic.
Thermostat Adjustment CAUTION Before adjusting thermostat(s), turn off power supply to the water heater. The temperature of the water can be changed by adjusting the thermostat(s). Before any work is done on the water heater, disconnect all power to the water heater by opening the switch at the main electrical circuit breaker or fuse box. Remove the access panels or front panel on tabletops, fold the insulation outward away from the controls.
MAINTENANCE IMPORTANT The water heater should be inspected at a minimum of annually by a qualified service technician for damaged components. DO NOT operate this water heater if any part is found damaged. Shut off the electric power whenever the water supply to the water heater is off. Shut off the electric power and water supply, drain the water heater completely to prevent freezing whenever the building is left unoccupied during the cold weather months.
Maintenance continued- 3. At least once a year, check the combination temperature and pressure relief valve to ensure that the valve has not become encrusted with lime. Lift the lever at the top of the temperaturepressure relief valve several times until the valve seats properly without leaking and operates freely. WARNING When lifting lever of temperature-pressure relief valve, hot water will be released under pressure.
Maintenance continued- Contact your local plumbing supplier or plumbing professional for replacement parts or contact the company at the address displayed on the rating plate of the water heater. For faster and better service, please provide the part name, model, and serial number(s) of the water heater(s) when ordering parts. READ THE WARRANTY FOR A FULL EXPLANATION OF THE LENGTH OF TIME THAT PARTS AND THE WATER HEATER ARE WARRANTED.
