GENERAL INFORMATION

FEATURES

This water heater contains the following features:

HEAT EXCHANGER -- The heat exchanger (coil) has 3/4” NPT

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.
