Raypak 85, 120 manual General Safety, Before Installation, Water Time to Produce Serious, Burn

2 - GENERAL SAFETY

To meet domestic hot water use needs, the high limit safety control on this boiler is adjustable up to 140°F (60°C).Water temperatures over 125°F (50°C) can cause instant severe burns or death from scalds.

When supplying general purpose hot water, the recommended initial setting for the temperature control is 125°F (50°C). Safety and energy conservation are factors to be considered when setting the water temperature on the thermostat. The most energy-efficient operation will result when the temperature setting is the lowest that satisfies the needs of the application.

Water temperature over 125°F (50°C) can cause instant severe burns or death from scalds. Children, disabled and elderly are at highest risk of being scalded.

•Feel water before bathing or showering.

•Temperature limiting valves are available.

NOTE: When this boiler is supplying general purpose hot water for use by individuals, a thermostatically controlled mixing valve for reducing point of use water temperature is recommended to reduce the risk of scald injury. Contact a licensed plumber or the local plumbing authority for further information.

Maximum water temperatures occur just after the boiler’s burner has shut off. To determine the water temperature being delivered, turn on a hot water faucet and place a thermometer in the hot water stream and read the thermometer.

WARNING: This boiler cannot supply hot water for use by individuals directly. A heat exchanger must be used in conjunction with this boiler to meet DHW needs.

T I M E / T E M P E R A T U R E RELATIONSHIPS IN SCALDS

Temperature	Burn
120°F	More than 5 minutes
125°F	1-1/2 to 2 minutes
130°F	About 30 seconds
135°F	About 10 seconds
140°F	Less than 5 seconds
145°F	Less than 3 seconds
150°F	About 1-1/2 seconds
155°F	About 1 second

The temperature of the water in the boiler can be regulated by using the Raypak Remote Control REC08. To comply with safety regulations, the control is set when shipped from the factory.

CAUTION: Hotter water increases the risk of scalding! There is a hot water scald potential if the thermostat is set too high.
