IMPORTANT SAFETY INFORMATION READ ALL INSTRUCTIONS BEFORE USING. DANGER! WATER TEMPERATURE SETTING Safety and energy conservation are factors to be considered when selecting the water temperature setting of a water heater’s remote control. Water temperatures above 125°F (52°C) can cause severe burns or death from scalding. Be sure to read and follow the warnings outlined on the label pictured below.
DANGER! NATURAL GAS AND LIQUEFIED PETROLEUM MODELS Both LP and natural gas have an odorant added to aid in detecting a gas leak. Some people may not physically be able to smell or recognize this odorant. If you are unsure or unfamiliar with the smell of LP or natural gas, ask the gas supplier. Other conditions, such as “odorant fade”, which causes the odorant to diminish in intensity, can also hide or camouflage a gas leak.
