CAUTION: Operation of this water heater in air contaminated by perchloroethylene, any chlorinated hydrocarbon or strong oxidizing agents, will result
in serious damage to brass orifices, internal steel parts and void the warranty.
IMPORTANT – BURNER MUST BE LEVEL. Models containing a cast iron burner are equipped with an adjustable air shutter. The air shutter on the front of the main burner must be adjusted when the water heater is installed. See installation instructions for proper air shutter adjustment procedures.
STATE OF CALIFORNIA NOTICE
WARNING: This water heater must be braced, anchored or strapped to avoid falling or moving during an earthquake. See instructions for correct installation
procedures.
WARNING: If not installed, operated and maintained in accordance with the manufacturer’s instructions this product could expose you to substances in the fuel
or form combustion which can cause death or serious illness including, cancer, birth defects or other reproductive harm.
SUITABLE FOR WATER (PORTABLE) HEATING AND SPACE HEATING
Toxic chemicals, such as used for boiler treatment, shall not be introduced into potable water heater used for space heating. This water heater may never be connected to any existing heating system or component(s) previously used with a nonpotable water heater appliance.
THERMOSTAT ADJUSTMENT
The thermostat dial is adjusted to its lowest temperature position when shipped from the factory. When adjusting the thermostat it should be remembered that lower temperature settings are more energy efficient. To adjust the thermostat, turn the dial clockwise until the minimum acceptable temperature is set. It is suggested that the starting point setting not exceed the “HOT” mark [approximately 120°F (49° C)] on the thermostat, as indicated in Figure 2.

DANGER
Hotter water increases the risk of scald injury. Scalding may occur within five (5) seconds at a temperature setting of 135°F (57°C). To protect against hot water injury, install an anti-scald tempering 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 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 3). 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.

MAINTENANCE
WARNING
Water heaters are heat producing appliances. To avoid damage or injury there shall be no materials stored against the water heater or vent-air intake system and proper care shall be taken to avoid unnecessary contact (especially by children) with the water heater and vent-air intake system. UNDER NO
CIRCUMSTANCES SHALL FLAMMABLE MATERIALS, SUCH AS GASOLINE OR PAINT THINNER BE USED OR STORED IN THE VICINITY OF THIS WATER HEATER, VENT-AIR INTAKE SYSTEM OR IN ANY LOCATION FROM WHICH FUMES COULD REACH THE WATER HEATER OR VENT-AIR INTAKE SYSTEM.
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. Regular inspection and maintenance of the water heater and vent-air intake system will help to ensure 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 resctrictions.
WARNING! The ventilation air system may be HOT.
3.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 on page 7.
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.
