Use and Care Manual

PLUMBING AND WIRING

(Optional to save additional energy dollars) In the bottom of the tee (branch) vertically down,

install an NPT tube adapter. Then install two sweat street 90° elbows. This acts as a thermal

loop to prevent thermal siphon action of hot water

EXPANSION TANK

A thermal expansion tank may be required in the system designed for potable water use, to

offset the expansion of stored water as the temperature is elevated (only in systems where

there is no return valve, a back flow preventer, a water meter, or anywhere pressure can

build up as the water is heated). See typical expansion tank on following page.

CONTROL

Install control element into well and tighten in place with screws on control body. Thermal

conductive paste is recommended. Once the control is operational, it is very important to

make sure the control is maintaining the desired operating temperature.

WIRING

All wiring is to be done in accordance with all applicable local and state codes. Turn off all

power related to the boiler starting and wiring procedures. It is recommended that a dis-

connect switch be installed between the boiler control and water heater.

CAUTION

RE-INSPECTION OF T&P RELIEF VALVES: Temperature and Pressure Relief Valves

should be inspected AT LEAST ONCE EVERY THREE YEARS, and replaced, if

necessary, by a licensed plumbing contractor or qualified service technician, to ensure

that the product has not been affected by corrosive water conditions and to ensure that

the valve and discharge line have not been altered or tampered with illegally. Certain

naturally occurring conditions may corrode the valve and its components over time,

rendering the valve inoperative. Such conditions can only be detected if the valve and

its components are physically removed and inspected. Do not attempt to conduct an

inspection on your own. Contact your plumbing contractor for a re-inspection to assure

continuing safety.

DANGER

WARNING: FAILURE TO RE-INSPECT THIS VALVE AS DIRECTED COULD RESULT IN

UNSAFE TEMPERATURE OR PRESSURE BUILDUP WHICH CAN RESULT IN SERIOUS

INJURY OR DEATH AND/OR SEVERE PROPERTY DAMAGE.
