FEATURES
This water heater contains the following features:
HEAT EXCHANGER --
female fittings.
These water heaters with stainless steel single-wall heat
exchangers meet the Uniform Plumbing Code for installation in
all potable water systems provided that:
The boiler water (including additives) is practically non-
toxic, having toxicity rating of class of 1 as listed in
Clinical Toxicology of Commercial Products.
The boiler water pressure is limited to maximum 30 psig
by approved relief valve.
The heat transfer medium is potable water or contains only
substances that are recognized as safe by the U.S. Food
and Drug Administration (FDA).
The pressure of the heat transfer medium is maintained
less than the normal minimum operating pressure of the
potable water system.
ADJUSTABLE THERMOSTAT – The temperature may be
adjusted from approximately 80°F (27°C) to approximately
160°F(72°C). The aquastat (thermostat) is factory set at
120°F(49°C). It is recommended that lower temperatures be used
to avoid the risk of scalding. Refer to the Section VII of this
manual. It is further recommended, in all cases, that the water
temperature be set for the lowest temperature that satisfies your
hot water needs. This will also provide the most energy efficient
operation of the water heater and minimizes scale formation.
Setting the water heater temperature at 120°F(49°C) will reduce
the risk of scalds. Some locations require settings to specific
lower temperatures.
