NOTE:

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

(2)Higher stored water temperature increases the ability of the water heater to supply desired quantities of hot water, however remember-

Incorrect piping of the cold water supply to the system may result in excessive low temperature operation causing condensate formation on the primary heat exchanger and operational problems. The cold water supply piping must be installed in the discharge piping from the heater to the storage tank. This allows the cold water to be tempered in the storage tank before entering the heater. See typical installation drawings provided with the unit for correct piping. Higher water temperatures reduce the volume of condensate formed.

HIGH WATER TEMPERATURE

LIMIT CONTROL

A Manual Reset High Limit control is located on the left front of the left front side of the control panel, beside the Command Display. Additional switches, alarm indicating lights and optional low water cut-off control switches are also located on this panel. The setting of this control knob limits maximum discharge water temperature. The water heater or hot water supply boiler temperature limit control is adjustable up to a fixed maximum setting of 200°F (93°C). A red reset button, located beside the knob, must be pushed whenever water temperature has exceeded the set point of the manual reset limit. The temperature of the water in the heat exchanger must drop a minimum of 15°F (8.3°C) below the setting of the manual reset high limit control before the reset function can be activated. A red indicating light is illuminated when the water temperature exceeds the setting of the high limit control. A status point alarm of Over Temp will be displayed in the Command Display when water temperature exceeds the Setpoint Temperature programmed into the Excel 10 control.

CAUTION￿

 

OPTIONAL RELIEF VALVE

 

 

 

Hotter water increases the risk of scald injury. Setting the temperature selector to higher settings provides hotter water, which increases the risk of scald injury.

The manufacturer recommends the use of a properly sized thermostatic mixing valve to supply domestic hot water at temperatures less than 110°F (43.3°C). Storing the water at a higher temperature and thermostatically mixing the water will decrease the size of the storage tank and increase the available quantity of mixed hot water. Storing water at higher temperatures can help to control the level of condensate formed and help prevent the growth of water born bacteria. Caution! Adequate care MUST be taken to prevent potential scald injury when storing water at 140°F (60°C) and hotter.

WARNING￿

Should overheating occur or the gas supply fail to shut off, do not turn off or disconnect the electrical supply to the pump. Instead, shut off the gas supply at a location external to the appliance.

This water heater or hot water supply boiler is normally supplied with a temperature and pressure relief valve sized in accordance with applicable codes. Units may be supplied with an optional pressure only relief valve. When a water heater or hot water supply boiler equipped with this optional relief valve is piped to a separate storage vessel, the storage vessel must have a properly installed temperature and pressure relief valve which complies with local codes.

THERMAL EXPANSION

A relief valve that discharges periodically may be due to thermal expansion in a closed system. A water heater or hot water supply boiler installed in a closed system, such as one with a backflow preventer or check valve installed in the cold water supply, shall be provided with means to control expansion. Contact the water supplier or local plumbing inspector on how to correct this situation. Do not plug or cap the relief valve discharge!

CATHODIC PROTECTION

Hydrogen gas can be produced in a hot water system that has not been used for a long period of time (generally two weeks or more). Hydrogen gas is extremely flammable. To prevent the possibility of injury under these conditions, we recommend the hot water faucet be open for several minutes at the kitchen sink before you use any electrical appliance which is connected to the hot water system. If hydrogen is present, there will be an unusual sound such as air escaping through the pipe as the hot water begins to flow. There should be no smoking or open flames near the faucet at the time it is open.
