Internet Version for Reference Only GENERAL INFORMATION This gas-fired water heater’s design is certified by CSA International under the American National Standard Z21.10.1 - (as indicated on the rating plate) and CSA 4.1-M - (as indicated on the rating plate). This water heater must be installed in accordance with local codes or, in the absence of local codes, the National Fuel Gas Code, ANSI Z223.1-Latest Edition) and/or in Canada CAN/CGA B149 Installation Codes (Latest Editions).
Internet Version for Reference Only General Information continued- A sacrificial anode is used to extend tank life. The removal of this anode, for any reason, will nullify the warranty. In areas where water is unusually active, an odor may occur at the hot water faucet due to a reaction between the sacrificial anode and the impurities in the water. If this should happen, an alternative anode may be purchased from the supplier that installed this water heater.

Internet Version for Reference Only THERMOSTAT ADJUSTMENT 160°F Control 180°F Control Figure 17 The thermostat dial is set to its lowest temperature setting when shipped from the factory. Remember that lower temperature settings are more energy efficient. Adjust the temperature by turning the thermostat dial. It is suggested that the starting point setting not be greater than the ” “ or “ “mark on the thermostat dial (approximately 120°F [48.9°C]) as indicated below.
Internet Version for Reference Only 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.
