SECTION III
GENERAL INFORMATION
FEATURES
This water heater contains the following features:
HEAT EXCHANGER -- The heat exchanger (coil) has 3/4" NPT
female fittings.
Water heaters with a double-wall heat exchanger meet the Uniform
Plumbing Code for installation in all potable water systems. The double-
wall construction provides protection in the event that either the potable
or hydronic heat exchanger barrier is penetrated. The fluid will move
along in integrated leak path within the heat exchanger, leaving the
exchanger through a weep hole located in the fittings. If a confirmed
leak occurs, contact the plumbing professional who installed the water
heater or the manufacturer, listed on the rating plate, for additional
guidance.
This indirect-fired water heater is appropriate for all potable heating
systems, even where a single-wall exchanger is not approved by the
authority having jurisdiction.
ADJUSTABLE THERMOSTAT – The temperature may be adjusted
from approximately 80°F to approximately160°F. The thermostat is
factory set at 120°F. 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.
Setting the water heater temperature at 120°F will reduce the risk of
scalds. Some states require settings to specific lower temperatures.
