WATER HEATER SAFETY Your safety and the safety of others are very important. We have provided many important safety messages in this manual and on your appliance. Always read and obey all safety messages. This is the safety alert symbol. This symbol alerts you to potential hazards that can kill or hurt you and others. All safety messages will follow the safety alert symbol and either the word “DANGER” or “WARNING.
INSTALLING YOUR GAS WATER HEATER Important Information About This Water Heater installed in accordance with Massachusetts Plumbing and Fuel Gas Code 248 CMR Section 2.00 and 5.00. A data plate identifying your water heater can be found next to the gas control valve/thermostat. When referring to your water heater, always have the information listed on the data plate readily available.
Do not use or store flammable products such as gasoline, solvents, or adhesives in the same room or area near the water heater. If such flammables must be used, all gas burning appliances in the vicinity must be shut off and their pilot lights extinguished. Open the doors and windows for ventilation while flammable substances are in use.
IMPORTANT: The water heater should be located in an area where leakage of the tank or connections will not result in damage to the area adjacent to the water heater or to lower floors of the structure. Due to the normal corrosive action of the water, the tank will eventually leak after an extended period of time. Also any external plumbing leak, including those from improper installation, may cause early failure of the tank due to corrosion if not repaired.

Chimney Connection Listed Lined Chimney IMPORTANT: Before connecting a vent to a chimney, make sure the chimney passageway is clear and free of obstructions. The chimney must be cleaned if previously used for venting solid fuel appliances or fireplaces. Also consult local and state codes for proper chimney sizing and application or, in the absence of local and state codes, the “National Fuel Gas Code”, ANSI Z223.1(NFPA 54)-latest edition. • 3 ft.
Water System Piping 7. Piping Installation Piping, fittings, and valves should be installed according to the installation drawing (Figure 13). If the indoor installation area is subject to freezing temperatures, the water piping must be protected by insulation. Water supply pressure should not exceed 80% of the working pressure of the water heater. The working pressure is stated on the water heater’s data plate.
Closed System/Thermal Expansion Please note the following: • The system should be installed only with piping that is suitable for potable (drinkable) water such as copper, CPVC, or polybutylene. This water heater must not be installed using iron piping or PVC water piping. • Use only pumps, valves, or fittings that are compatible with potable water. • Use only full flow ball or gate valves. The use of valves that may cause excessive restriction to water flow is not recommended.
Temperature and Pressure Relief Valve IMPORTANT: Only a new temperature and pressure relief valve should be used with your water heater. Do not use an old or existing valve as it may be damaged or not adequate for the working pressure of the new water heater. Do not place any valve between the relief valve and the tank. WARNING The Temperature & Pressure Relief Valve: • Must not be in contact with any electrical part. • Must be connected to an adequate discharge line.
5. Locate the slit running the length of a section of pipe insulation. Some jurisdictions may require a backflow preventer in the incoming cold water line. This may cause the temperature and pressure relief valve on the water heater to discharge or weep due to expansion of the heated water. A diaphragm-type expansion tank suitable for potable water will normally eliminate this weeping condition. Please read and follow the manufacturer’s instructions for the installation of such tanks. 6.
Electrical Connections WARNING Before plugging in the water heater, always make sure: • The Voltage and frequency correspond to that specified on the water heater. • The electrical outlet has the proper overload fuse or breaker protection. • Water heater to be located within 6 feet of 120VAC outlet. • Unit is to connect to a 120VAC electrical supply outlet (extension cord is not allowed). • The water heater and the outlet are properly grounded.
Important Information About This Water Heater This gas water heater was manufactured to voluntary safety standards to reduce the likelihood of a flammable vapor ignition incident. The new technology used in meeting these standards makes this product more sensitive to installation errors. Please review the following checklist and make any required installation upgrades or changes. Questions? Call 1-877-817-6750.
OPERATING YOUR WATER HEATER Operating Instructions WARNING Read and understand these directions thoroughly before Explosion Hazard attempting to operate the water heater. Make sure the view port is not missing or damaged (See Figure 25). Make sure the tank is completely filled with water before operating the water heater. The gas control valve/thermostat has a “On/ Off Switch” and needs to be turned on before water heater is operational.
Checking The Draft Water Heater Operation Figure 17 below shows the water heater’s sequence of operation when a call for heat is initiated. The ignition control module will attempt to light the burner three times. If the ignition control does not detect ignition it will enter lockout mode, indicated by display flashing status code (see status code 3 page 28 and/or status code 9 page 29). WARNING Burn Hazard Do not touch vent. Doing so can result in burns.
Burner Flames or if there is a local code or state law requiring a certain temperature water at the hot water tap, then you must take special precautions. In addition to using the lowest possible temperature setting that satisfies your hot water needs, a means such as a mixing valve, should be used at the hot water taps used by these people or at the water heater. Mixing valves are available at plumbing supply or hardware stores, see Figure 14.
B. To increase the temperature press and release the “HOTTER” button until the desired setting is reached. NOTE: Should overheating occur or the gas supply fail to shut off, turn off the manual gas control valve to the appliance. An undersized water heater will cause more condensation. The water heater must be sized properly to meet the family’s demands for hot water including dishwashers, washing machines and shower heads.
Powered Anode Operation Draining and Flushing To protect the glass-lined water tank from corrosion through electrolysis, this water heater is equipped with a non sacrificial powered anode rod. The powered anode rod is non sacrificial and should not need to be replaced unless damaged. It is recommended that the tank be drained and flushed every 6 months to remove sediment which may build up during operation. The water heater should be drained if being shut down during freezing temperatures.
Temperature and Pressure Relief Valve WARNING Manually operate the temperature and pressure relief valve at least once a year to make sure it is working properly. To prevent water damage, the valve must be properly connected to a discharge line which terminates at an adequate drain. Standing clear of the outlet (discharged water may be hot), slowly lift and release the lever handle on the temperature and pressure relief valve to allow the valve to operate freely and return to its closed position.
