MAKING WATER CONNECTIONS

WARNING! A tempering valve or other similar device must be installed between the outlet of the hot water service and any faucet.

Connect water lines to rear of unit. Suitable fittings must be used in rear of hot and cold water connections. DO NOT glue metal fittings. This will void warranty.
NOTE: Inside each fitting is a suitable fill tube installed by manufacturer. Its purpose is to enhance water circulation. DO NOT REMOVE THE PLASTIC FILL TUBES. Fill tank with water. Always open both the cold and hot water taps when filling vehicle water tank to allow air pockets to be forced out of the water heater. When tank is filled, turn  off taps and check for leaks at connections. After leak testing, drain water from tank.

MAKING GAS CONNECTIONS

Connect 3/8” flare fitting gas supply to gas connection located in the control housing. When making the gas connection, hold the gas fitting on the valve with a wrench when tightening the flare nut. Failure to hold fitting secure could result in a gas leak due to fitting being damaged. NOTE: It will be necessary to remove the grommet from the control housing, make the gas connection at the valve, then reinstall grommet. Refer to AS5601 for gas pipe size

WARNING! It is imperative that grommet and gas line through grommet be caulked air tight. If not tightly sealed, moisture and potential harmful flue products could vent through opening and into living area of trailer. (See Figure 4.)

Before leaving: check all connections for gas leaks with soap and water. Do not use a naked flame for detecting leaks. Ignite burner to ensure correct operation of gas valve, burner and ignition. Observe stability of the flame. When satisfied with the heater, please instruct the user on the correct method of operation. In case the appliance fails to operate correctly after all checks have been carried out, refer to the authorised service provider in your area.

WARNING! Before the circuit breaker for the electric element is turned to the “ON” position, the water heater tank must be filled with water. See “SAFETY WARNINGS”

MAINTENANCE

WARNING! If the user of this appliance fails to maintain it in the condition in which it was shipped from the factory or if the appliance is not used solely for its intended purpose or if appliance is not maintained in accordance with the instructions in this manual, then the risk of a fire and/or the production of carbon monoxide exists which can cause personal injury, property damage or loss of life.
WARNING! For your safety, all repairs should be performed by an authorised service person.

A. If the burner flame burns yellow, check for an obstruction in the burner or flue box. Also, check to be sure there is no flame present at burner orifice or burner whenever main gas valve is closed. This can be checked by turning the circuit breaker switch to the “OFF” position. A stiff brush is recommended for the removal of soot deposits.
B. Frequent checks should be made of the grommet on the gas inlet to assure tight seal. (See “Making Gas Connections”).
C. Periodically check wiring and wire connection to be sure wiring is not damaged/frayed and that all terminals and connections are tight and in compliance with codes (See “Making Electrical Connections”).

1. Mains Water Connection- For correct performance and warranty of the unit, when connected to mains water supply, pressure must be limited to approximately 350 kPa (50 PSI) by the use of a suitable pressure regulator. Failure to do so will void warranty.
2. A suitable 1/2” BSPT fitting must be used for coupling HWS to water supply.
3. Water supply is an overall factor.
4. Tanks should be drained and flushed regularly – how often depends on soluble/silt content in water. Outback areas will be more of a problem than major city supplies.
5. Do not use bore water. This will void your warranty as the salt contents of bore water are extremely high.
6. The life of the anodes, which are a low valve replacement part, varies with water quality. Anodes must be inspected periodically. Use only genuine Suburban anode rods. Use of other anodes may void the waranty. Please see Anode Protection Section.
7. Your water system should be operated periodically even though the van is not being used, at least twice per week.
8. Anodes must be checked every 6 (six) months. Please see Anode Protection Section.

SAFETY WARNINGS

WARNING! It is imperative that the water heater tank be filled with water before operating the water heater. Operation of the water heater without water in the tank may result in damage to the tank and/or controls. This type of damage is not covered by the limited warranty.
WARNING! Hydrogen gas may result if you have not used this heater for two weeks or more. HYDROGEN GAS IS EXTREMELY FLAMMABLE. To reduce the risk of injury under these conditions, open the hot water faucet for several minutes at the kitchen sink before you use any electrical appliance connected to the hot water system. If hydrogen is present, you probably will hear an unusual sound such as air escaping through the pipe as the water begins to flow. Hydrogen gas may be present even after water has been drained from the tank. Open faucet at sink and allow system to vent for several minutes (5-10 minutes). Do not smoke or have any open flame near the open faucet. Do not attempt to light pilot or main burner. On DSI models, be sure the switch is “OFF”. Should overheating occur, or the gas supply fail to shut off, shut off the manual gas valve to the appliance before shutting off the electrical supply.Do not use this appliance if any part has been submerged under water. Immediately call an authorised service technician to inspect the appliance and to replace any part of the control system and any gas control that has been submerged under water Do not alter the operation of your water heater nor change the design/construction of your water heater. Accessories are being marketed for RV products which we do not recommend. For your safety, only factory authorized parts are to be used on your water  heater.Periodically inspect the vent for obstructions or presence of soot. Soot is formed whenever combustion is incomplete. This is your visual warning that the water heater is operating in an unsafe manner. If soot is present, immediately shut the water heater down and contact your dealer or an authorised service person. When considering add-on rooms, porch or patio, attention must be given to the venting of your water heater. For your safety, do not terminate the vent on your water heater inside add-on rooms, screen porch or onto patios. Doing so will result in products of  combustionbeing vented into the rooms or occupied areas. Never operate the heater if you smell gas. Do not assume that the smell of gas in your RV is normal. Any time you detect the odor of gas, it is to be considered life threatening and corrected immediately. Extinguish any open flames including cigarettes and evacuate all persons from the vehicle. Shut off gas supply at LP gas bottle. (See Safety notice on front cover of this manual.) Pressure relief valve to be operated at least once every 6 months to remove lime deposits and verify it is not blocked. Failure to do so may result in heater exploding. Continuous leakage from valve may indicate a problem with unit.
NOTE: Always open both the cold and hot water faucets when filling vehicle water tank to allow air pockets to be forced out of the water heater. When water flows from the heater faucets, close both faucets.
WARNING! Do not store or use combustible materials or liquids near or adjacent to this heater. The appliance shall not be installed in any location where flammable liquids or vapors are likely to be present. Be sure the power is “OFF” to the water heater ignition system during any type of refueling and while vehicle is in motion or being towed.
WARNING! The thermostat on your water heater is not adjustable. It is a temperature sensing limit designed to maintain a temperature above 60°C to comply with AS/NZS 3500 Part 4.2. Water temperatures over 60°C can cause severe burns instantly or death from scalds; therefore, be careful when using hot water. Children, disabled and elderly are at highest risk of being scalded. Always feel water before bathing or showering. Children or infirm persons must not adjust, light, or operate any electrical or gas controls on this unit.

THERMOSTAT AND MANUAL RESET

For all Models

The model water heaters listed above are equipped with a high temperature limit as a cut-off device. Temperature above 82°C will cause manual reset button to trip shutting down main burner. To activate burner, the water temperature must be below 37°C. Push reset button to re-activate burner.

For Models SW4DERA, SW4DEFA, SW6DERA, and SW6DEFA

DANGER! The operation of a thermal cut-out indicates a possibly dangerous situation. Do not reset the thermal cut-out until the water heater has been serviced by a qualified person.

The model water heaters listed above are equipped with a high temperature limit as a cut-off device. Temperature above 82°C will cause manual reset button to trip shutting down the electric element. To activate element, the water temperature must be below 37°C. Push reset button to re-activate the electric element.

ANODE PROTECTION

The temperature and pressure relief valve is designed to open if the temperature of the water within the heater reaches 98.9 degrees Celsius, or if the water pressure in the heater reaches 700 kPa. Recreational vehicle water systems are closed systems and during the water heating cycle the pressure build-up in the water system will reach 700 kPa. When this pressure is reached, the pressure relief valve will open and water will drip from the valve. This dripping will continue until the pressure is reduced to below 700 kPa. Once the pressure has dropped below 700 kPa, the valve will close. This condition is normal and does not indicate a defective relief valve. The water may drip from the discharge pipe of the pressure relief device, this pipe must be left open to the atmosphere.

WARNING! Do not plug, cap or reduce the outlet pressure and temperature valve.
The pressure-relief device is to be operated regularly to remove lime deposits and to verify that it is not blocked.
DANGER! Failure to operate the relief valve easing gear at least once every six months may result in the water heater exploding. Continuous leakage of water from the valve may indicate a problem with the water heater.

WATER WEEPING OR DRIPPING FROM PRESSURE RELIEF VALVE

You may experience water weeping or dripping from your water heater’s Pressure and Temperature (P & T) Relief Valve when your water heater is operating. Water weeping or dripping from the P & T Valve does not always mean the P & T Valve is defective. As water is heated, it expands. The water system in a recreational vehicle is a closed system and does not allow for the expansion of heated water. When the pressure of the water system exceeds the relieving point of the P & T Valve, the valve will relieve the excess pressure. Suburban recommends that a check valve not be installed directly at the inlet to the water heater tank. This  willin crease weeping of the pressure relief valve.

One way to reduce the frequency of this occurrence is to maintain an air pocket at the top of the water heater tank. This air pocket will form in the tank by design. However, it will be reduced over time by the everyday use of your water heater. To replenish this air pocket:

1. Turn off water heater.
2. Turn off cold water supply line.
3. Open a tap in the RV.
4. Pull out on the handle of the Pressure Relief (P & T) Valve and allow water to flow from the valve until it stops.
5. Release handle on P & T Valve – it should snap closed.
6. Close tap and turn on cold water supply; as the tank fills, the air pocket will develop.

Repeat this procedure as often as needed to reduce the frequency of the weeping of the P & T Valve. If the weeping persists after following this procedure, you may elect to install an expansion or accumulator tank in the cold water line to relieve
the pressure caused by thermal expansion. Suitable fittings are required to be installed in the pressure relief valve for piping the water away. The hole through which the piping passes must be sealed water tight.
The discharge pipe must not be reduced in size along its length. The length and number of bends should be kept to a minimum and should be supported in a manner to reduce the risk of crushing or blockage. A discharge pipe connected to the pressure relief device is to be installed in continuously downward direction and in a frost free environment. Please contact your local dealer for assistance.

DRAINING AND STORAGE INSTRUCTIONS

If unit is to be stored during the winter months, the heater must be drained to prevent damage in the case of freezing temperatures.

1. Turn off gas supply to the water heater.
2. Turn off pressure pump on the water system.
3. Open both hot and cold water taps.
4. pen the drain on the water heater. (Remove anode rod)
5. Follow RV manufacturer’s instructions for draining of the entire water system

NOTE: Be certain to refill water heater with water before re-lighting the appliance.

ODOR FROM HOT WATER SYSTEM

Odor from the hot water system is not a service problem and many water supplies contain sufficient amounts of sulphur to produce an odor. The odor is similar to rotten eggs and is often referred to as “sulphur water”. It is not harmful – only unpleasant to smell. Sulphur water can be caused by a chemical action or by bacteria. The solution to eliminate is chlorination of the water system. Add about 17.75 cL of chlorinated common household liquid bleach to each 38 Liters in the water tank. Then run the chlorinated water throughout the system, opening each faucet one at a time until you smell the chlorine. Let the RV sit for a few days and the chlorine should take care of the problem. Then you will need to take care of the chlorine. Remove the chlorine by flushing the system with fresh water. This may take several attempts. You may consider adding a filtering system that removes chlorine and prevents sulphur water. If the sulphur or rotten egg smell continues, flush the system once again as described above and replace anode rod as necessary

REMOVING WATER HEATER

1. Shut off gas supply and disconnect gas supply line from water heater.
2. Shut off water supply. Drain water from tank following instructions under “Draining and Storage”.
3. Disconnect hot and cold water lines from water heater.
4. Remove screws or nails securing control housing to framed opening.
5. Slide heater out. To reinstall, follow instructions in manual under “Installation Instructions”.

WINTERIZING

If your water heater plumbing system is equipped with a bypass kit, use it to close off the water heater, drain the water heater completely and leave the water heater closed off (out of the system) in the bypass position particularly if you are introducing antifreeze into the plumbing system. Antifreeze can be very corrosive to the anode rod creating premature failure and heavy sediment in the tank. If the plumbing system is not equipped with a bypass kit, and you intend to winterize by adding antifreeze to the system, remove the anode rod (storing it for the winter) and replace it with a 19mm drain plug

HIGH ALTITUDE DERATION

Suburban’s water heaters are certified by nationally recognized testing laboratories for operation without modifications at altitudes up to 4,500 feet. Operation above this elevation may require derating by 4 percent for every 1,000 feet above sea level. As an example, at 8,000 feet, the water heater should be derated approximately 32 percent. If the unit is not properly derated, lack of sufficient oxygen for combustion may produce improper burner operation. Pilot outage caused by burner lift-off or sooting from a yellow burner may occur indicating the possibility of carbon monoxide. You may also notice a lack of efficiency in heating the water because of incomplete combustion of the burner at these higher altitudes. Consult with the local gas company, your dealer, an RV service agency or Suburban Manufacturing Company for proper derating of the unit. Change-out of the orifice (derating) should be done by the dealer or an authorised service agency.
NOTE: It is important that once the unit has returned to lower elevation (below 4,500 feet) this high altitude deration and pilot adjustments (if equipped) be reversed for proper operation of the unit.
