Water heater temperature adjustment

General notes

•Household water usage patterns will affect water temperature at any faucet or shower.

•Occasionally check temperature at each point of use, then adjust thermostat accordingly.

•Always recheck temperature after adjusting thermostat.

•When hot water is used in repeated small quantities, a “stacking” effect can develop in hot water tank. The upper layer of water in tank can be much hotter than lower layers.

•Lowering the thermostat setting or installing automatic mixing valves as indicated in these instructions will reduce water tempera- ture levels. Consult your installer or service technician.

At no time should boiler limit control be set above 200°F. This can cause severe personal injury, death or substantial property damage if ignored.

Studies have indicated that dangerous bacteria, includ- ing legionella pneumophila, can form in the potable water distribution system if certain minimum water temperatures are not maintained. Contact your local health department for more information.

Setting the thermostat

1.The water heater thermostat is factory set to its lowest temperature. This may or may not be suitable for your needs.

2.Turn thermostat knob clockwise to increase water tempera- ture.

3.Turn thermostat knob counter-clockwise to reduce water tem- perature.

4.When decreasing temperature setting, the stored hot water must be drawn off before checking temperature at faucet.

5.Check water temperature at a hot water faucet immediately after first heating cycle. Further temperature adjustment may be neces- sary as water heating system is used. Recheck water temperature at faucet after adjustment.

6.When adjusting thermostat, be sure boiler limit control is set a minimum 20°F higher.

Hot Water Can Scald!

•Water heated to temperature for clothes washing, dish washing and other sanitizing needs can scald and cause permanent injury.

•Children, elderly, and infirm or physically handi- capped persons are more likely to be permanently injured by hot water. Never leave them unattended in bathtub or shower. Never allow small children to use a hot water tap or draw their own bath.

•If anyone using hot water in the building fits the above description, or if state laws or local codes require certain water temperatures at hot water taps, you must take special precau- tions:

•Use lowest possible temperature setting.

•Install some type of tempering device, such as an automatic mixing valve, at hot water tap or water heater.Automatic mixing valve must be selected and installed according to valve manufacturer’s recommendations and instructions.

•Water passing out of drain valves may be extremely hot. To avoid injury:

•Make sure all connections are tight.

•Direct water flow away from any person.

Protection must be taken against excessive tem- perature and pressure! — Installation of a tem- perature & pressure (T&P) relief valve (provided with water heater) and a thermostatic mixing valve (provided by installer) is required.
