Water heated to a temperature which satisfies space
heating, clothes washing, dish washing, and other
sanitizing needs can scald and cause permanent injury
upon contact. Short repeated heating cycles caused by
small hot-water uses can cause a temperature increase of
the hot water by 30F° higher than the heater's temperature
settings. If you choose a higher temperature setting,
Thermostatic Mixing Valves (see Figure 6) located at
each point-of-use are particularly important to help avoid
scalding.
This appliance has been design certified as complying with
ANSI/CSA Standard for water heaters and are considered
suitable for combination Water (Potable) Heating and
Space Heating but not space heating only applications.
The water supply pressure should not exceed 80 psi. If this
occurs, a pressure reducing valve with a bypass should be
installed in the cold water inlet line. This should be placed
on the supply to the entire house in order to maintain equal
hot and cold water pressures.
Some people are more likely to be permanently injured
by hot water than others. These include the elderly,
children, the infirm and the physically/mentally disabled.
Table 1 (published by U.S. Government Memorandum,
1978) shows the approximate time-to-burn relationship
for normal adult skin. If anyone using hot water provided
by the water heater being installed fits into one of these
groups, special precautions must be taken.
