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.
