• Water supply shut-off devices that activate based on the water pressure differential between the cold water and hot water pipes connected to the water heater. • Devices that will turn off the gas supply to a gas water heater while at the same time shutting off its water supply. WARNING... -
Page 6: Hard Water
HARD WATER Where hard water conditions exist, water softening or the threshold type of water treatment is recommended. This will protect the dishwashers, coffee urns, water heaters, water piping and other equipment. See MAINTENANCE section for details of tank cleanout procedure. AIR REQUIREMENTS KEEP APPLIANCE AREA CLEAR AND FREE OF COMBUSTIBLE MATERIALS, GASOLINE AND OTHER FLAMMABLE VAPORS AND LIQUIDS. -

INSTALLATION OF VENT SYSTEM WARNING THE OPTIONAL INTAKE VENTING ARRANGEMENT AND THE EXHAUST VENTING ARRANGEMENT MUST BE INSTALLED TO RUN DIRECTLY TO THE OUTDOORS AND NOT IN ANY WAY BE CONNECTED TO ANOTHER VENTING SYSTEM (I.E. FURNACE, DRYERS OR SPACE HEATERS). IT IS CRUCIAL THAT THE VENTING ARRANGEMENT BE KEPT SEPARATE FROM OTHER VENTING SYSTEMS. -
Page 12: Control And Switches
The ON/OFF Switch is a single-pole, single-throw rocker switch. This switch provides 120V from the line source to the heater. CAUTION THE WATER HEATER IS POLARITY SENSITIVE. BEFORE APPLYING ELECTRICITY TO THIS HEATER BE CERTAIN THAT SUPPLY NEUTRAL WIRE TO GROUND CHECK INDICATES ZERO VOLTAGE. -
Page 13: Connection Of Gas Pipe
WARNING THE HEATER IS NOT INTENDED FOR OPERATION AT HIGHER THAN 10.5" (2.59 KPa) WATER COLUMN SUPPLY GAS PRESSURE. HIGHER GAS SUPPLY PRESSURES REQUIRE SUPPLEMENTAL REDUCING SERVICE REGULATION. EXPOSURE TO HIGHER GAS SUPPLY PRESSURE MAY CAUSE DAMAGE TO THE GAS CONTROLS WHICH COULD RESULT IN FIRE OR EXPLOSION. -

3. This unit may never be connected to any existing heating system or component(s) previously used with non-potable water heating appliance. 4. When the system requires water for space heating at temperatures higher than required for domestic water purposes, a tempering valve must be installed. -
Page 16: Using The Electronic Controller
The first temperature on this screen is the temperature of the water inside the tank. The second temperature on this screen is the Operating Set Point. The Operating Set Point is the temperature at which the water heater will maintain the water inside the tank. The third line on the screen is a text description of the Operational State of the water heater (please see Operating States for more details). -
Page 17: Operating States
In the main desktop screen, there are some specific Operating States that are indicated on the status line. These are summarized below: 3. Adjusting the Operating Set Point The Operating Set Point of this water heater determines the regulated temperature for the water in the tank. This parameter is adjusted in the Temperature menu. -

5. Fault and Alert Conditions This water heater is equipped with electronic controls that have the ability to monitor almost all aspects of the water heater operation. In the case that there is an undesirable or unsafe condition that occurs, the water heater controls will detect this condition and determine the appropriate action. -
Page 19: Viewing The Fault History
PRIOR TO START UP REQUIRED ABILITY Be certain that the water heater is full of water, that air is purged from all lines, there are no leaks (gas and water), and all inlet water lines are open. The following test equipment should be on hand (all test equipment must be acclimated to ambient temperature before calibration and use.) -
Page 20: Operating Instructions
ADJUSTMENT PROCEDURE INITIAL START-UP Main line gas pressure to the water heater for natural gas should be between a maximum of 10.5" (2.59Kpa for natural gas) W.C. (14.0"/3.45Kpa for propane) and a minimum as shown in Table 4: that is, for Natural Gas 4"... -

Page 30: Manifold Kits
MANIFOLD KITS Precision cut type “L” all copper State manifold kits assure water flow balance of all units. Without this balance, the full water heating and storage potential of the system cannot be achieved. Plus, the units with the higher water flow may have a shortened life. Dimensions shown are for minimum space occupied by the water heaters assemblies. -
Page 31: Checklist And Service Information
• Contacts click or snap as the heater starts and stops. • Transformers often hum. WATER LEAKAGE IS SUSPECTED 1. Check to see if the water heater drain valve is tightly closed. Also check the cleanout opening for leakage. 2. The apparent leakage may be condensation which forms on cool surfaces of the heater and piping. -
Page 32: Replacement Parts
MOTOR WILL NOT RUN 1. Confirm 120V AC to the controller. Also, to verify correct polarity, check for 120 V AC between hot supply and ground. If there is no voltage, check for a loose connection where it connects to the controller. - Page 33 NOTES:...
