Installation and Operation Instructions Manual
WARNING: If the information in these instructions is not followed exactly, a
fire or explosion may result causing property damage, personal injury or death.
– Do not store or use gasoline or other flammable
vapors and liquids in the vicinity of this or any
other appliance.
– WHAT TO DO IF YOU SMELL GAS
• Do not try to light any appliance.
• Do not touch any electrical switch; do not
use any phone in your building.
WARNING
Improper installation, adjustment, alteration,
service or maintenance can cause serious injury
or property damage. Refer to this manual. For
assistance or additional information, consult a
qualified installer or service agency.
WARNING
Install in accordance with all local codes. In the
absence of local codes, refer to NFPA 54
CAUTION
The recommended temperature for normal
residential use is 120°F. The dial on the aquastat
does not always reflect the out-coming water
temperature and it could occasionally exceed
120°F. Variation in out-coming temperature could
be based on factors including but not limited to
usage patterns and type of installation. Test water
at the tap nearest to the water heater. See page 37
for measuring the out- coming water temperature.
WARNING
Hotter water increases the risk of scald injury.
Before adjusting the water temperature setting,
read this instruction manual. Temperatures at
which injury occurs vary with the person's age
and the length of exposure. The slower reaction
time of children, elderly or physically or mentally
challenged persons increases the scalding hazard
to them. It is recommended that lower water
temperatures be used where these exposure hazards
exist. Households with small children or invalids
may require a temperature setting less than 120°F
to prevent accidental contact with hot water.
To produce less than 120°F, use point-of-use
temperature limiting devices.

    SECTION II: GENERAL INFORMATION WHEN YOU RECEIVE YOUR NEW WATER HEATER Check the new equipment to see if all components are in good condition. If damage is observed or parts appear to be missing, contact your wholesaler. WATER TREATMENT/FILTRATION In areas where poor water conditions are suspected (i.e. lime, iron, and other minerals), it is essential that the water be tested and appropriate action taken to prevent damage to the water heater and ensure the quality of the water.
  • Page 6 SECTION II: GENERAL INFORMATION ANODE RODS The water heater is supplied with a factory installed powered anode system to prevent corrosion of internal tank components. Specifically, the type of anode system that is used is an impressed-cur- rent anode system. This system uses a power supply that regulates the protective current output based on actual conditions inside the tank.
  • Page 7 SECTION II: GENERAL INFORMATION BACKFLOW PREVENTER (CLOSED SYSTEM) Some local municipal codes and ordinances require the use of these devices on potable (domestic) water lines. Where backflow preventers, check valves, or pressure regulating valves are required, it will be necessary to install a thermal expansion tank (designed for use with potable water) in order to prevent pressure build up in the water heater and associated piping, which could cause the T&P valve to discharge.
  • Page 8 (standoffs) are located between the wall and the water heater. The standoffs may be field supplied or a kit may be purchased from Bock Water Heaters, Inc. One kit per water heater is required. Figure 3 shows the seismic strapping secured to an outside wall.

Wind around the water heater allows combustion exhaust to be carried away and contamination of combustion air and lead to nuisance lockouts and increase maintenance on parts. provides fresh combustion air.
  • Page 11 SECTION III: PRE-INSTALLATION LOCATION CAUTION Do not install this water heater under an overhang less than 3 ft (91.4 cm) from its top. The top of the water heater is defined as the highest point of the exhaust vent termination. The area under the overhang must be open on 3 sides.
  • Page 12 SECTION III: PRE-INSTALLATION GAS SUPPLY LINE Prior to installation, contact your local gas utility to confirm that sufficient gas service is available for the water heater. The gas meter must have adequate capacity to supply the rated maximum gas input of the water heater in addition to other gas fired equipment connected to the meter. Minimum Gas Supply Pressure The gas supply must be capable of maintaining a minimum pressure at the inlet of the gas control during water heater operation at maximum input.

Allow the water heater to warm up to the factory adjusted setpoint and wait until the main operating control has shut off gas to the burner. Wait 30 seconds following shut-off of gas, then adjust the setpoint to a higher temperature.
  • Page 24 SECTION V: OPERATION Following adjustment of the setpoint to a higher temperature (see Figure 17), the main burner should relight. Next, adjust the setpoint to a lower temperature (i.e. back to 120° F) and the gas valve will close, extinguishing the burner flame. The thermostat should be adjusted to the minimum setting that will meet the hot water needs of the application.
