Installation & Service Manual

7Domestic water heaters

￿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).
