GENERAL INFORMATION

This water heater must be installed in accordance with The Federal

Manufactured Home Construction And Safety Standard (H.U.D. Title 24, Part

3280.707d2) or CAN/CSA Z240 MH series, mobile home. In the absence of such a standard, the water heater should be installed in accordance with the

Standard For Mobile Homes (ANSI/NFPA NO. 501-B1977).

The warranty for this water heater is in effect only when the water heater is installed, adjusted, and operated in accordance with these Installation and

Operating Instructions. The manufacturer will not be liable for any damage resulting from alteration and/or failure to comply with these instructions.

This water heater is of the closed combustion type (direct venting) where all the combustion air is supplied from the outdoors through the air intake and all combusted gas products are vented directly to the outside by means of the roof jack. No draft diverter (vent hood) is required for this water heater.

INTERTEK has tested a representative sample of this water heater design for its safety of operation. The ETL listing of this water heater includes the field installation of the following components: roof jack, air intake tube, and heater tie down materials. These components for field installation may have been shipped with this heater and must be installed according to these instructions

(see figure 1). No other components are approved for use with this water heater.

This water heater has been designed and certified for the purpose of heating potable water. The installation and use of this water heater for any purpose other than the heating of potable water may cause damage to the water heater, create a hazardous condition, and nullify the warranty.

CAUTION

Incorrect operation of this appliance may create a hazard to life and property and will nullify the warranty.

WARNING

Prior to connecting the gas supply line to a gas fired water heater, ensure that the gas supply line does not have moisture/water or dirt/scale inside the gas line. Commonly this check is done at the lowest point in the gas distribution system prior to gas burning

appliances.

Do not use this appliance if any external part to the tank has been submerged in water. You should contact a qualified service technician to inspect the appliance and to replace any part of the control system including the combination gas control which has been submerged in water. See the Gas

Connections section of this manual before servicing or replacing a water heater that has had any external part to the tank submerged in water.

This water heater has been manufactured for operation at altitudes from sea level to 2000 feet (610m) (unless otherwise specified on the water heater).

For use of this appliance at an elevation greater than 2000 feet (610m), contact the dealer or manufacturer listed on the rating plate for information on any necessary modification. Uncorrected operation of this appliance may create a hazard to life and property.

DANGER

Do not store or use gasoline or other flammable, combustible, or corrosive vapors and liquids in the vicinity of this or any other

appliance.

Make sure to check the rating plate and combination gas control on the water heater to be certain that the type of gas being supplied corresponds with the marking on the rating plate and combination gas control.

A sacrificial anode is used to extend tank life. The removal of this anode, for any reason, 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 the impurities in the water. If this should happen, an alternative anode may be purchased from the supplier that installed this water heater. This will minimize the odor while protecting the tank. Additionally, the water heater should be flushed with appropriate dissolvers to eliminate any bacteria.

INSTALLATION

Locating the Water Heater

This water heater MUST NOT be installed in any location where gasoline or flammable vapors are likely to be present, unless the installation is such to eliminate the probable ignition of gasoline or flammable vapors.

The location of this water heater is of the utmost importance. Before installing this water heater, read the Installation section of these instructions. DO NOT

locate the water heater where water lines could be subjected to freezing

temperatures. Make sure the cold water pipes are not located directly

above the gas control so that condensate during humid weather does not

drip on the controls.

WARNING

DO NOT ATTEMPT TO LIGHT ANY GAS APPLIANCE IF YOU ARE

NOT CERTAIN OF THE FOLLOWING:

• Liquefied petroleum gases/propane gas and natural gas have an odorant added by the gas supplier that aids in detection of the gas.

• Most people recognize this odor as a “sulfur” or “rotten egg” smell.

• Other conditions, such as “odorant fade” can cause the odorant to diminish in intensity, or “fade”, and not be as readily detectable.

• If you have a diminished sense of smell, or are in any way unsure of the presence of gas, immediately contact your gas supplier from a neighbor’s telephone.

• Gas detectors are available. Contact your gas supplier or plumbing professional for more information.

6

Installation (Locating The Water Heater) continued-

WARNING

Liquefied petroleum gases/propane gases are heavier than air and will remain at floor level if there is a leak. Basements, crawl spaces, closets and areas below ground level will serve as pockets for accumulation of leaking gas. Before lighting, smell all around the appliance area for gas.

Be sure to smell next to the floor.

IF YOU SMELL GAS:

• Do not try to light any appliance.

• Do not touch any electric switch; do not use any telephone in your

building.

• Immediately call your gas supplier from a neighbor’s telephone.

Follow the gas supplier’s instructions.

• If you cannot reach your gas supplier, call the fire department.

DO NOT OPERATE APPLIANCE UNTIL LEAKAGE IS CORRECTED!

This water heater MUST be installed indoors out of the wind and weather.

This water heater must be located in an area where leakage of the tank, water line connections, or the combination temperature and pressure relief valve will not result in damage to the area adjacent to the water heater or to lower floors of the structure. When such locations cannot be avoided, a suitable drain pan must be installed under the water heater (Refer to drain pan installation section for more information.). The drain pan must have a minimum length and width of at least 4 in. (10.2 cm) greater than the diameter of the water heater and must not restrict proper combustion air flow to the water heater. The drain pan, as described above, can be purchased from your plumbing professional. The drain pan must be piped to an adequate drain. The piping must be at least 3/4 inch (1.9 cm) in diameter and pitched for proper drainage.

To comply with NSF requirements this water heater is to be: a) Sealed to the floor with sealant, in a smooth and easily cleanable way, or b) Installed with an optional leg kit that includes legs and/or extensions that provide a minimum clearance of 6” beneath the water heater.

Water Connections

NOTE: BEFORE PROCEEDING WITH THE INSTALLATION, CLOSE THE

MAIN WATER SUPPLY VALVE.

After shutting off the main water supply, open a faucet to relieve the water line pressure to prevent any water from leaking out of the pipes while making the water connections to the water heater. After the pressure has been relieved, close the faucet. The COLD water inlet and HOT water outlet are identified on the top of the water heater. The fittings at the cold water inlet and hot water outlet are dielectric waterway fittings with 3/4” NPT male thread. Make the proper plumbing connections between the water heater and the plumbing system to the house. Install a shut-off valve in the cold water supply line.

CAUTION

If sweat fittings are to be used, DO NOT apply heat to the nipples on top of the water heater. Sweat the tubing to the adapter before fitting the adapter to the water connections. It is imperative that heat is not applied to the nipples containing a plastic liner.

WARNING

FAILURE TO INSTALL AND MAINTAIN A NEW, LISTED 3/4” X 3/4”

TEMPERATURE AND PRESSURE RELIEF VALVE WILL RELEASE

THE MANUFACTURER FROM ANY CLAIM WHICH MIGHT RESULT

FROM EXCESSIVE TEMPERATURE AND PRESSURES.

12

Installation (Water connections) continued-

If this water heater is installed in a closed water supply system, such as the one having a back-flow preventer in the cold water supply, provisions must be made to control thermal expansion. DO NOT operate this water heater in a closed system without provisions for controlling thermal expansion. Your water supplier or local plumbing inspector should be contacted on how to control this situation.

After 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.

WARNING

For protection against excessive temperatures and pressure, install temperature and pressure protective equipment required by local codes, but not less than a combination temperature and pressure relief valve certified by a nationally recognized testing laboratory that maintains periodic inspection of production of listed equipment or materials as meeting the requirements of the Standard for

Relief Valves and Automatic Gas Shutoff Devices for Hot Water Supply

Systems, ANSI Z21.22 or the Standard CAN1-4.4. Temperature and Pressure and the Standard CAN1-4.4, Temperature, Pressure, Temperature and

Pressure Relief Valves and Vacuum Relief Valves. The combination temperature and pressure relief valve must be marked with a maximum set pressure not to exceed the maximum working pressure of the water heater. The combination temperature and pressure relief valve must also have an hourly rated temperature steam BTU discharge capacity not less than the hourly rating of the water heater.

Install the combination temperature and pressure relief valve into the opening provided and marked for this purpose on the water heater.

Note: Some models may already be equipped or supplied with a combination temperature and pressure relief valve. Verify that the combination temperature and pressure relief valve complies with local codes. If the combination temperature and pressure relief valve does not comply with local codes, replace it with one that does. Follow the installation instructions above on this page.

Install a discharge line so that water discharged from the combination temperature and pressure relief valve will exit within six (6) inches (15.2 cm) above, or any distance below the structural floor and cannot contact any live electrical part. The discharge line is to be installed to allow for complete drainage of both the combination temperature and pressure relief valve and the discharge line. The discharge opening must not be subjected to blockage or freezing. DO NOT thread, plug or cap the discharge line. It is recommended that a minimum clearance of four (4) inches (10.2 cm) be provided on the side of the water heater for servicing and maintenance of the combination temperature and pressure relief valve.

Do not place a valve between the combination temperature and pressure relief valve and the tank.

13

Installation (Water connections) continued-

WARNING

Hydrogen gas can be produced in an operating water heater that has not had water drawn from the tank for a long period of time (generally two weeks or more). Hydrogen gas is extremely flammable. To prevent the possibility of injury under these conditions, we recommend the hot water faucet to be open for several minutes at the kitchen sink before you use any electrical appliance, which is connected to the hot water system. If hydrogen is present, there will be an unusual sound such as air escaping through the pipes as hot water begins to flow. Do not smoke or have open flame near the faucet at the time it is open.

This water heater can deliver scalding temperature water at any faucet in the system. Be careful whenever using hot water to avoid scalding injury. Certain appliances such as dishwashers and automatic clothes washers may require increased temperature water. By setting the thermostat on this water heater to obtain the increased temperature water required by these appliances, the potential for scald injury increases. To protect against injury, you should install an ASSE approved mixing valve in the water system. This valve will reduce point of discharge temperature by mixing cold and hot water in branch supply lines. Such valves are available from the manufacturer of this water heater or a local plumbing supplier. Please consult with a plumbing professional.

Water temperature over 125°F can cause severe burns instantly or death from scalds.

Children, disabled and elderly are at highest risk of being scalded.

Review this instruction manual before setting temperature at water heater.

Feel water before bathing or showering.

Temperature limiting valves are available.

Gas Connections

The gas supply lines must meet all requirements of the National Fuel Gas Code

(ANSI Z223.1-Latest Edition), or in Canada CAN/CGA B149.1 Natural Gas

Installation Code (Latest Edition) or CAN/CGA B149.2 Propane Installation Code

(Latest Edition).

The minimum permissible gas supply pressure for the purpose of input adjustment is one (1.0) inch (0.25 kPa) water column above the operating manifold pressure.

See the rating plate and gas valve for the manifold pressure and gas type. The maximum permissible gas supply pressure is fourteen (14.0) inches (3.5 kPa) water column for natural gas and liquefied petroleum gases/propane gas.

1. Connect this water heater only to the type of gas (Natural or Propane gas) as shown on the rating plate. Use clean black iron pipe or equivalent material approved by local codes and ordinances. (Dirt and scale from the pipe can enter the gas valve and cause it to malfunction). The inlet gas line must have a minimum length of three (3) inches (7.6 cm) drip leg (sediment trap) installed as close to the water heater’s gas valve as possible. A ground joint union must be installed as close to the water heater as possible in the gas supply line feeding the water heater to permit servicing of the water heater. Compounds used on the threaded joints of the gas piping must be resistant to the action of liquefied petroleum gases/propane gas. DO NOT apply pipe dope to the gas valve inlet and make certain that no pipe dope has become lodged in the inlet screen of the gas valve. Extreme care must be taken to ensure no pipe dope enters the gas valve. Avoid excessive torque when tightening the gas supply line to the gas valve. Excessive torque may result in cracking of the gas valve housing and could create a gas leak. When tightening gas supply line to L.P. control, it is recommended to hold the inlet body of the control securely with an adequate wrench. The suggested maximum torque is 31.5 ft. lbs. (4.4 kg-m).

WARNING

The manufacturer of this water heater will not be liable for any damage or injury caused as a result of a cracked gas inlet as a result of excessive torque.

2. This water heater and its gas connection must be leak tested before placing the water heater in operation. Check for gas leaks with a soap and water solution and a brush or a commercial leak detector fluid. NEVER USE A MATCH OR

OPEN FLAME FOR TESTING!

CAUTION

The water heater and individual shutoff valve must be disconnected from the gas supply piping system during any pressure testing of the system at test pressures in excess of 1/2 psi (3.5 kPa). The water heater must be isolated from the gas supply piping system by closing its manual shutoff valve during any pressure testing of the gas supply system at test pressures equal to or less than

1/2 psi (3.5 kPa). The supply line must be capped when not connected to the water heater.

3. While checking for leaks care must be taken to prevent solution from contacting the electrical connections at the control. If electrical connections at the control become wet, they must be thoroughly dried before attempting to operate the water heater.

TO DRAIN THE WATER HEATER

Should it become necessary to completely drain the water heater, make sure you follow the steps below:

1. For the White Rogers control, rotate the thermostat dial clockwise to the lowest possible position, OR for the Robertshaw controls, rotate the thermostat dial counter-clockwise to the lowest possible position.

2. For the White Rogers control, partially depress and rotate the gas control knob clockwise to the “OFF” position, OR for the Robertshaw control, rotate the gas control knob clockwise to the “OFF” position.

3. Shut off the gas supply to the water heater.

4. Close the cold water supply shut-off valve.

5. Open the drain valve on the water heater by turning the knob counterclockwise . The drain valve has threads on the end that will allow the connection of a standard hose coupling.

6. Open a hot water faucet to allow air to enter the system.

To refill the water heater, refer to “To Fill the Water Heater.”

Thermostat Adjustment

Figure 9

The thermostat dial is set to its lowest temperature setting when shipped from the factory. Remember that lower temperature settings are more energy

efficient. Adjust the temperature by turning the thermostat dial. It is suggested that the starting point setting not be greater than the ” “ mark on the thermostat dial (approximately 120°F [48.9°C]) as pictured above. Rotate the thermostat dial clockwise to decrease the temperature setting.

Rotate the thermostat dial counter-clockwise to increase the temperature setting. Adjust the dial until the minimum acceptable temperature is achieved (See Figure 9 above for approximate temperature settings).

General Operation continued-

DANGER

Hotter water increases the risk of scald injury. Scalding may occur within five (5) seconds at a temperature setting of 140°F (60°C). To protect against hot water injury, install an ASSE approved mixing valve in the water system. This valve will reduce point of discharge temperature by mixing cold and hot water in branch water lines. A licensed plumbing professional or local plumbing authority should be consulted.

Note: This water heater is equipped with an energy cut out device to prevent overheating. Should overheating occur or the gas supply fail to shut off, turn off the manual gas control valve to the appliance and call a qualified service technician.

Note: Whenever the water heater is filled with cold water, condensate will form on the cool tank surface and drops of water will fall on the hot burner and combustion chamber surfaces producing a “sizzling” noise.

Condensation is normal and does not indicate a leak. It will disappear when the tank becomes heated.

Burner Flame Check

Steel Burner: These models are equipped with self-adjusting air mixture and do not have an adjustable air shutter (See Figure 12). At periodic intervals, a visual check of the main burner and pilot flames should be made to determine if they are burning properly. The main burner flame should light smoothly from the pilot.

WARNING

Do not run out of propane gas. Damage to the water heater may occur.

MAINTENANCE

IMPORTANT

The water heater should be inspected at a minimum annually by a qualified service technician for damaged components and/or joints not sealed. DO NOT operate this water heater if any part is found damaged or if any joint is found not sealed.

The following maintenance should be performed by a qualified service technician at the minimum periodic intervals suggested below. In some installations, the maintenance interval may be more frequent depending on the amount of use and the operating conditions of the water heater.

24

Maintenance Continued-

Regular inspection and maintenance of the water heater and vent-air intake system will help to insure safe and reliable operation.

1. Annually check the operation of the thermostat.

2. The flow of combustion and ventilation air MUST NOT be restricted. Clear the combustion air openings of any dirt, dust, or other restrictions.

WARNING

3.

The ventilation air system may be HOT.

At all times keep the water heater area clear and free from combustible materials, gasoline and other flammable vapors and liquids.

4. Bi-annually conduct a visual check of the main and pilot burner flames to determine that they are burning properly. See Burner Flame Check section.

5. Annually remove the inner door and main burner assembly to clean orifices and related parts of any dirt or other foreign material. Inspect the burner ports for obstructions or debris and clean with a wire brush as needed.

Wire brush and/or vacuum clean the combustion chamber as needed to remove scale deposits and debris. NOTE: It is imperative for proper operation of the water heater that the inner door be replaced in the original location.

WARNING

Do not run out of propane gas. Damage to the water heater may occur.

WARNING

When lifting the lever of the combination temperature and pressure relief valve, hot water will be released under pressure.

Be careful that any released water does not result in bodily injury

or property damage.

6.

7.

At least once a year, check the combination temperature and pressure relief valve to insure that the valve has not become encrusted with lime. Lift the lever at the lever at the top of the valve several times until the valve seats properly without leaking and operates freely.

Monthly drain off a gallon of water to remove silt and sediment.

WARNING

THIS WATER MAY BE HOT .

8.

If the combination temperature and pressure relief valve on the appliance discharges periodically, this may be due to thermal expansion in a closed water supply system. Contact the water supplier or local plumbing inspector on how to correct this situation. Do not plug the combination temperature and pressure relief valve outlet.

9. A combination sacrificial anode rod/hot water outlet nipple has been installed to extend tank life. The anode rod should be inspected periodically and replaced when necessary to prolong tank life. Water conditions in your area will influence the time interval for inspection and replacement of the anode rod .

25

Maintenance Continued-

Contact the plumbing professional that installed the water heater or the manufacturer listed on the rating plate for anode replacement information.

The use of a water softener may increase the speed of consumption. More frequent inspection of the anode is needed when using softened (or phosphate treated) water.

The vent system must be inspected at least once a year to ensure against leakage of exhaust products.

CAUTION

FOR YOUR SAFETY, DO NOT ATTEMPT REPAIR OF COMBINATION

GAS CONTROL, BURNERS OR GAS PIPING. REFER REPAIRS TO A

QUALIFIED SERVICE TECHNICIAN.

Contact your supplier or plumbing professional for replacement parts or contact the company at the address given on the rating plate of the water heater.
