your gas supplier for local requirements governing the temperature setting. Remember, no water heating system will provide exact temperature at all times. Allow a few days of operation at this setting to determine the correct temperature setting consistent with your needs.

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:

￿CAUTION

Hotter water increases the risk of scald

injury.

Incorrect piping of the cold water supply to the system may result in excessive low temperature operation causing condensate formation on the 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 condensate formation.

￿CAUTION

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 140°F. Storing the water at a higher temperature and thermostatically mixing the water will increase the available quantity of mixed hot water, greatly reduce the possibility of condensate formation on the heat exchanger and help prevent the growth of water born bacteria. Adequate care MUST be taken to prevent potential scald injury when storing water at 140°F and hotter.

• Water temperature over 125°F (52°C) can cause severe burns instantly or death from scalds.

• Children, disabled and elderly are at highest risk of being scalded.

• See instruction manual before setting temperature at heating appliance.

• Feel water before bathing or showering.

• If this appliance is used to produce water that could scald if too hot, such as domestic hot water use, adjust the outlet control (limit) or use temperature limiting valves to obtain a maximum water temperature of 125°F (52°C).

￿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.

AUTOMATIC VENT DAMPERS

Automatic vent dampers are not required or furnished on potable water heaters. All water heaters will have a plug installed in the damper terminal on the side of the control panel to allow operation without a vent damper. The damper plug MUST be in place if an optional vent damper is not used on a water heater. Water heaters with inputs of 360,000 Btu/hr and less may be ordered with the vent damper as an option. Remove the damper plug from the terminal to connect an optional vent damper wire harness. The optional damper must be properly installed and the wire harness plugged into the terminal on the side of the control panel to allow the unit to function. See the “Automatic Vent Damper” section in the basic portion of the manual.

￿CAUTION

Do not install an optional vent damper within 6"

(152mm) of combustible materials.

OPTIONAL RELIEF VALVE

This water heater/hot water supply boiler is normally supplied with a temperature and pressure relief valve(s) sized in accordance with applicable codes. Units may be supplied with an optional pressure only relief valve(s). When a water heater/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.
