GENERAL INFORMATION
FEATURES
This water heater contains the following features:
HEAT EXCHANGER -- The heat exchanger (coil) has 1” NPT
female fittings.
These water heaters with single-wall heat exchangers meets 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.
• The equipment is permanently labeled to indicate that only
additives recognized as safe by the FDA shall be used in the
heat transfer medium.
ADJUSTABLE AQUASTAT – The temperature may be adjusted
from 80°F to 160°F. The aquastat (thermostat) was adjusted to
120°F before the heater was shipped from the factory. It is
recommended that lower temperatures be used to avoid the risk of
scalding. Refer to the “Warnings” and the section on SCALDING in
“Section VII – Operating Instructions.” 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.
