DO NOT set inlet pressure higher than maximum indicated on rating plate of gas valve (13˝ W.C.). Isolate unit from gas supply line by closing its individual manual shutoff valve during any pressure testing ≤ 1/2 psig. WARNING EXPLOSION OR FIRE store or use gasoline or other flammable vapors and liquids in the vicinity of this or any other appliance. • Should overheating occur, or gas supply fail to shut off, turn OFF manual gas control valve to appliance, or turn gas OFF at the LP tank. On ELECTRONIC IGNITION MODEL turn operating switch to OFF position and remove red wire from left hand terminal of ECO switch or turn gas OFF at the LP tank. • Use with LP gas only. • Shut off gas appliances and pilot lights when refueling. • On PILOT RELIGHT MODELS, turn off the ignition module when refueling gasoline tanks or LP tanks. • Turn gas OFF at the LP tank when vehicle is in motion. This disables all gas appliances and pilot lights. Gas appliances must never be operated while vehicle is in motion. Unpredictable wind currents may be created which could cause flame reversal in the burner tube, which could result in fire damage. The thermal cut off fuse could also be unnecessarily activated resulting in a complete shutdown of the water heater requiring replacement of the thermal cut off. See maintenance of electronic ignition water heaters for further explanation of the thermal cut off. • LP tanks must be filled by a qualified gas supplier only. • DO NOT WARNING FIRE AND/OR EXPLOSION • DO NOT use matches, candles or other sources of ignition when checking for gas leaks. 11. Turn on gas and check water heater and all connections for gas leaks with leak detecting solution. 12. Fill water heater tank, check all connections for water leaks. PRESSURE-TEMPERATURE RELIEF VALVE WARNING HOW TO OPERATE YOUR WATER HEATER EXPLOSION • • • • CAUTION Valve is not serviceable, it must be replaced. Tampering with valve will result in scalding injury. Tampering with valve will void warranty. DO NOT place a valve, plug or reducing coupling on outlet part of relief valve. FIRE • Do not smoke or have any flame near an open faucet. If water heater has not been used for more than two weeks, hydrogen gas may form in water line. Under these conditions to reduce the risk of injury, open hot water faucet for several minutes at kitchen sink before you use any electrical appliance connected to hot water system. THIS VALVE IS A SAFETY COMPONENT AND MUST NOT BE REMOVED FOR ANY REASON OTHER THAN REPLACEMENT. This water heater is equipped with a tempera- ture and pressure relief valve (FIG 3-G) that complies with standard for Relief Valves and Automatic Gas Shutoff Devices for Hot Water Systems, ANSI Z21.22. If hydrogen gas is present, you will probably hear sounds like air escaping through the pipe as water begins to flow. WARNING If you use a discharge line, do not use a reducing coupling or other restriction smaller than outlet of relief valve. Allow complete drainage of both valve and line. SCALDING INJURY • Do not tamper with pilot orifice. FOR REPLACEMENT PARTS: • DO NOT install anything less than a combination temperature-pressure relief valve certified by a nationally recognized testing laboratory that maintains periodic inspection of product of listed equipment or materials, as meeting requirements for Relief Valves and Automatic Gas Shutoff Devices for Hot Water Supply Systems, ANSI Z21.22. Valve must have a maximum set pressure not to exceed 150 psi. • Install valve into opening provided and marked for this purpose on water heater. • Installation must conform with local codes or in the absence of local codes, American National Standard for Recreational Vehicles, ANSI A119.2/NFPA 50IC. • For an external electrical source, ground this unit in accordance with National Electrical Code ANSI/NFPA70.

AFTERMARKET WATER HEATING ELEMENT DEVICES WARNING EXPLOSION / BURN INJURY • DO NOT alter water heater, it will void warranty. • DO NOT USE Aftermarket heating elements, they can lack critical safety 5. To Adjust Main Burner (FIG 4): 1. Loosen air shutter screw (4-A). 2. Slide air shutter (4-B) to right until some yellow appears in main burner flame. 3. Move air shutter (4-B) to left until yellow disappears. 4. Retighten air shutter screw (4-A). controls. • Use of Aftermarket heating elements can lead to an out of control heating of water tank and a catastrophic wet side explosion. The use of any aftermarket heating element devices may also result in damage to components or water heater. Atwood’s written warranty states - “failure or damage resulting from any alteration to our water heater is the owner’s responsibility”. Any alteration, like the addition of an aftermarket heating element device, will void the warranty. Read MAINTENANCE AND CARE INSTRUCTIONS ELECTRONIC IGNITION OPERATION 1. Refer to WIRING DIAGRAM FIG 12. Place remote switch in ON position. 2. If remote switch light stays on longer than 15 seconds, place remote switch in OFF position and wait 5 minutes. 3. Repeat step one. 4. For complete shut-down and before servicing: a. Place remote switch in OFF position. b. Remove red wire from left hand terminal of ECO switch (ECO to valve). 5. If heater fails to operate due to high water temperature, a lockout condition occurs (indicator light on). After water cools, reset switch in OFF position for at least 30 seconds, then turn to ON position. 6. If a lockout condition persists contact an Atwood Service Center. Read MAINTENANCE AND CARE INSTRUCTIONS & ELECTRONIC IGNITION MAINTENANCE GENERAL INFORMATION PILOT RELIGHT OPERATION ELECTRONIC IGNITION MAINTENANCE • LP and Water system must be turned on. • Have gas pressure tested periodically. Should be set at 11 inches of water column with three appliances running. • Drain water heater at regular intervals (at least one time during the year). • Drain water heater before storing RV for the winter or when the possibility of freezing exists. • Keep vent and combustion air grill clear of any obstructions. • Periodically, compare flame of main and pilot burners with FIG 5 and main burner adjustments in HOW TO OPERATE YOUR WATER HEATER. • When water heater is not in use set temperature control lever (White Rogers) or dial (Robertshaw) to lowest possible position. This will reduce the effects of low outdoor temperatures on calibration of temperature control mechanism. 1. Turn the switch located on the spark module to the ON position. 2. Read PILOT OPERATION instructions. 3. For complete shut down, turn lighting control knob on thermostat and spark module switch to the OFF position. Read MAINTENANCE AND CARE INSTRUCTIONS • The water heater comes factory-equipped with a fused circuit board, which will protect the circuit board from wiring shorts. If the fuse should activate, the water heater will not operate. Before replacing the fuse, check for a short external to the board. Once the short is corrected, replace the 2 amp fuse with a mini ATO style fuse. Do not install a fuse larger than 3 amps. • If the fuse is good and the unit is inoperative, check for excessively high voltage to the unit (more than 14 volts). • If the previous two steps did not solve the problem, check the thermal cut-off (FIG 3-I). The thermal cutoff is a device installed in the power supply line. This device will shut off electrical power and stop heater operation when activated. For example, if an obstruction within the flue tube should occur, as described in the Preventative Maintenance section, the burner flame/heat may contact the cutoff, resulting in a melting of the fuse element incorporated in the thermal cutoff. In order to restore power and proper operation of the water heater, the obstruction must be removed and the thermal cutoff must be replaced. GAS/ELECTRIC COMBINATION FUNCTION GAS OPERATION. When the gas switch is turned on, the unit will make three attempts to light. If for any reason there is no ignition, the unit will lockout and the red lockout lamp will illuminate. If the thermostat fails, the ECO will also lockout the unit, requiring resetting. Determine the reason for no ignition, correct it, and reset the gas ignition sequence by turning the switch off, then on. ELECTRIC OPERATION. When the electric switch is turned on, the relay at the rear of the unit will close and pass 110vac to the element. If the thermostat were to fail, the ECO will open and lockout the system. To correct, check the thermostat to assure good contact with the tank and reset the control by turning the electric switch off, then on. 4 A Pressure Temperature Relief Valve, dripping while the water heater is running, DOES NOT mean it is defective. During normal expansion of water, as it is heated in the closed water system of a recreation vehicle, the Pressure Temperature Relief Valve will sometimes drip. The Atwood water heater tank is designed with an internal air gap at the top of the tank to reduce the possibility of dripping. In time, the expanding water will absorb this air and it must be restored. Due to variations in water quality, the Pressure Temperture Relief Valve may have a shorter life and may need replacement within the water heater warranty period. If corrosion is detected, it will not be covered under warranty. PREVENTATIVE MAINTENANCE Spiders, mud wasps, and other insects can build nests in the burner tube. This will cause poor combustion, delayed ignition or ignition outside combustion tube. Listen for a change in burner sounds or in flame appearance from a hard blue flame to a soft lazy flame or one that is very yellow. These are indications of an obstruction in burner tube (FIG 4-C). Inspect and clean on a regular basis. a. Remove air shutter screw (FIG 4-A) and slide air shutter (FIG 4-B) down burner tube. b. Run a flexible wire brush down burner tube (FIG 4-D) until it is visible at end of burner tube. c. Vacuum burner where it enters combustion tube. d. Return air shutter to original position and replace screw. e. The orifice, burner tube and shutter must be aligned so that the shutter is not binding on the air tube. WARNING SCALDING INJURY • Turn off water heater before opening pressure-temperature relief HOW TO CLEAN PILOT MODELS - FIG 6 valve to establish air space. Storage water must be cool. 1. Check main burner orifice and pilot assembly for contamination (dirt, spider webs, etc.). 2. Clean main burner tube with small brush. 3. Main burner adjustment - open air shutter 1/4 way. 4. Low pilot flame. Check for contamination - if clean have the pilot orifice replaced. TO REPLACE THE AIR GAP FOLLOW THESE STEPS: 1. Turn off main water supply (the pump or water hook up source). 2. Let water cool or let run until cool. 3. Open the hot water faucet closest to the water heater. 4. Pull handle of pressure temperature relief valve straight out and allow water to flow until it stops. 5. Allow pressure temperature relief valve to snap shut; close faucet; turn on water supply. 6. Turn on water heater and test. • At least once a year manually operate pressure-temperature relief valve (FIG 10). When pressure-temperature relief valve discharges again, repeat above procedure. For a permanent solution, we recommend one of the following: • Install a pressure relief valve in cold water inlet line to water heater and attach a drain line from valve to outside of coach. Set to relieve at 100-125 PSI. • Install a diaphragm-type expansion tank in cold water inlet line. Tank should be sized to allow for expansion of approximately 15 oz. of water and pre-charged to a pressure equal to water supply pressure. These devices can be obtained from a plumbing contractor or service center. HOW TO CLEAN ELECTRONIC IGNITION MODEL 1. 2. 3. 4. 5. Check main burner orifice. Clean and adjust main burner. Main burner and valve manifold must align with each other Check electrode for cracked porcelain (FIG 4-E). Check electrode for proper gap - 1/8” between electrode and ground. 6. If module board functions intermittently, remove board and clean terminal block with pencil eraser (FIG 3-H). WATER HEATER TANK CARE WARNING SCALDING INJURY • Turn off water heater and allow time for water to cool before remov- ing drain plug to flush tank. WINTERIZING (FLUSHING) INSTRUCTIONS FLUSHING TO REMOVE UNPLEASANT ODOR To insure the best performance of your water heater and add to the life of the tank, periodically drain and flush the water heater tank. Before long term storage or freezing weather drain and flush the tank. 1. Turn off main water supply (the pump or water supply (the pump or water hook up source). 2. Drain Water Heater Tank by removing the drain plug. If the water flows sporadically or trickles instead of a steady stream of water, we recommend the following action; first open the Pressure Temperature Relief Valve to allow air into the tank and secondly, take a small gauge wire or coat hanger and poke through the drain opening to eliminate any obstructions. 3. After draining the tank, because of the placement of the Drain Plug, approximately two quarts of water will remain in the tank. This water contains most of the harmful corrosive particles. To remove these harmful corrosive particles flush the tank with either air or water. Whether using air or water pressure, it may be applied through the inlet or outlet on the rear of the tank or the Pressure Temperature Relief Valve. (If using the Pressure Temperature Relief Valve the Support Flange must be removed). The pressure will force out the remaining water and the corrosive particles. If you use water pressure, pump fresh water into the tank with the assistance of the on-board pump or use external water for 90 seconds to allow the fresh water to agitate the stagnant water on the bottom of the tank and force deposits through the drain opening. Continue repeating adding water and draining until the particles have been cleared from the water remaining in the tank. 4. Replace the Drain Plug and close the Pressure Temperature Relieve Valve. the approximately two quarts of water remining in the tank after draining will not cause damage to the tank should freezing occur. A rotten egg odor (hydrogen sulfide) may be produced when the electro galvanic action of the cladding material releases hydrogen from the water. if sulfur is present in the water supply the two will combine and produce an unpleasant smell. 1. Turn off main water supply. Drain the water heater tank and reinstall drain plug. Remove the pressure-temperature relief valve. Mix solution of 4 parts white vinegar to two parts water. With a funnel, carefully pour solution into tank. 2. Cycle water heater with the above solution, letting it run under normal operation 4-5 times. 3. Remove the drain plug and thoroughly drain all water from the tank. Flush the water heater to remove any sediment. You may flush the tank with air pressure or fresh water. pressure may be applied through either the inlet or outlet valves on the rear of the tank or through the pressure-temperature relief valve coupling located on the front of the unit. TO FLUSH TANK WITH AIR PRESSURE: Insert your air pressure through the pressure-temperature relief valve coupling. With the drain valve open, the air pressure will force the remaining water out of the unit. To flush tank with water pressure: Fresh water should be pumped into the tank with either the onboard pump or external water pressure. Continue this flushing process for approximately 5 minutes, allowing the fresh water to agitate the stagnant water on the bottom of the tank and forcing the deposits through the drain opening. 4. Replace drain plug and pressure-temperature relief valve. 5. Refill tank with fresh water that contains no sulphur. The Atwood water heater is designed for use in a recreation vehicle. If you use your vehicle frequently or for long periods of time, flushing the water heater several times a year will prolong the life of the storage tank.
