Time/Temperature Relation-

ships in Scalds

The chart shown above may be used as a guide in de-

termining the proper water temperature for your home.

Maximum water temperatures occur just after the boiler

has shut off. To find the water temperature being deliv-

ered, turn on a hot water faucet, place a thermometer

in the water stream and read the temperature.

CAUTION:

The  recommended  water  temperature

setting for normal residential use is 120°F (49°C).

When ordering parts, you must specify the model and

serial number of the water heater. When ordering under

warranty conditions, you must also specify the date of

installation.

Purchased parts are subject to replacement only under

the manufacturer’s warranty. Debits for defective re-

placement parts will not be accepted. Parts will be re-

placed in kind only per Raypak’s standard warranties.

Scalding

Water Temperature Setting

DANGER: 

Safety  and  energy  conservation  are

factors to be considered when selecting the water

temperature setting of a water heater’s temperature

control. Water temperatures above 125°F can cause

severe burns or death from scalding. Be sure to read

and  follow  the  warnings  outlined  on  the  label

pictured  below.  This  label  is  also  located  on  the

water heater.

DANGER: 

Households  with  small  children,

disabled, or elderly persons may require a 120°F or

lower control (thermostat) setting to prevent contact

with HOT water.

DANGER: 

Hotter water increases the potential for

Hot Water SCALDS.

NOTICE: 

Mixing valves are available for reducing

point-of-use  water  temperature  by  mixing  hot  and

cold water in branch water lines. Contact a licensed

plumber  or  the  local  plumbing  authority  for  further

information.

Water temperature over 125°F can

cause instant severe burns or death

from scalds.

Children, disabled, and elderly are

at highest risk of being scalded.

See instruction manual before set-

ting temperature at water heater.

Feel water before bathing or show-

ering.

Temperature  limiting  valves  are

available, see manual.
