Important Information

CONGRATULATIONS!

You have just purchased one of the finest water heater accessories on the market today!

This Installation and Operation Manual will explain in detail how to install and operate your new Setback Control. We strongly recommend you contact a plumbing professional for the installation of this new control.

We require that you carefully read this manual and the manual supplied with the water heater when questions arise. If you have any specific questions concerning your warranty, please consult the plumbing professional from whom your Setback Control was purchased. For your records, we recommend that you write the installation date for this control in the back of this manual.

This manual should be kept with the Setback Control.

Water Heater Setback Control:

This Setback Control works with the water heater gas control. It has the capability to adjust the setpoint of the water heater during periods where little or no hot water is required for use. The Setback Control adjusts the setpoint of a water heater similarly to the way a programmable thermostat does for a furnace.

Setback Control Features:

7 day / 4 period programming

Conserves energy

Hot water capacity indicator (provides an estimate of available hot water)

Battery back-upstores programming during a power outage

Can be programmed to comply with Sabbath requirements

Similar interface to furnace / air conditioning thermostats

Precision control of water temperature

Important Information

READ CAREFULLY

The following terms are used throughout this manual to bring attention to the presence of hazards at various risk levels, or to important information concerning product life.

DANGER

Indicates an imminently hazardous situation, which, if not avoided, will result in death, serious injury or substantial property damage.

CAUTION

Indicates potentially hazardous situation, which, if not avoided, may result in moderate or minor injury or property damage.

WARNING

Indicates a potentially hazardous situation, which, if not avoided, could result in death, serious injury or substantial property damage.

NOTICE

Indicates special instructions on installation, operation or maintenance, which are important but not related to personal injury hazards.

NOTICE

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

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.

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.

NOTICE

The lower the temperature setting, the greater the energy efficiency, both to heat the water and to maintain the storage temperature during standby periods. Lower water temperatures also extend tank life. Remember, no water heating system will provide exact temperatures at all times. Allow a few days of operation at this setting to determine the correct temperature setting consistent with the requirements for the installation.

-3-

Important Information

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.

CAUTION

This water heater, when set at a lower temperature setting, is not capable of producing hot water of sufficient temperature for sanitizing purposes.

WARNING

Do not operate the water heater or Setback Control without the Setback Control Junction Box Assembly cover in place.

Do not operate water heater and Setback Control with jumpered or absent controls or safety devices.

Turn off or disconnect the electrical power supply to the water heater and Setback Control before servicing. Label all wires prior to disconnection when servicing controls. Wiring errors can cause improper and dangerous operation. Verify proper operation after servicing.

All electrical wiring must be installed and grounded in accordance with local codes, or in the absence of local codes, the National Electrical Code, ANSI/NFPA 70 and/or CSA C22. Electrical Code.

For energy efficient operation of your water heater, the suggested initial water temperature setting is 120˚F (49˚C). During the winter season, or any cold period, you may desire a higher water temperature setting to adjust for the colder incoming water. This adjustment, however, may cause additional condensation to form on the cooler tank surface. This does not mean the tank is leaking. During summer months, the warmer incoming water temperatures will benefit the performance of your water heater and reduce the amount of condensation developed.

Condensation does not mean your tank is leaking. Over 40% of reported tank leaks on installation are proven to be condensation. To avoid unnecessary expense and inconvenience, make sure the tank is leaking before calling a service technician.

As was stated previously, the recommended water temperature during periods when hot water is required is 120˚F (49˚C). During setback periods, the recommended water temperature is 85°F (29°C). If it is possible that hot water will be needed during the Leave and/or Sleep periods, set the Setback to 105°F (41°C). This control may be used for the Sabbath. Please consult your local rabbi for recommended water temperatures and appropriate times for the Sabbath.

Initially, the Setback Control will default all water temperatures to the setpoint on the water heater gas control.
