EGS-I&S-01

NOTICE

Typical steam boiler without connections available below the water line is not recommended due to insufficient water temperature, especially during warmer months when the space heating system is not operational. Boiler water temperature at the bottom of a steam boiler can be 50°F lower than the boiler’s water temperature limit setting during such periods.

FILL BOILER SYSTEM

1.On new boiler installations, do not purge the boiler or space heating system through the water heater. During any boiler or space heating system flushing, cleaning, or purging, the water heater should be isolated to avoid possible attack on the carbon steel coil by chemical additives.

2.Purge air from boiler/water heater piping.

3.Check system for leaks. Repair as necessary.

DANGER

Positively assure all electrical connections are unpowered before attempting installation or service of electrical components or connections of the water heater or building. Lock out all electrical boxes with padlock once power is turned off.

WARNING

When installed, the water heater must be electrically grounded in accordance with local codes or, in the absence of local codes, with the National Electrical Code, ANSI/NFPA 70, and /or the CSA C22.1 Electric Code.

Failure to properly wire electrical connections to the water heater may result in serious physical harm.

Electrical power may be from more than one source. Make sure all power is off before attempting any electrical work.

ELECTRICAL CONNECTIONS

Install electric wiring in accordance with National Electric Code or the Canadian Electrical Code and local regulations. See the boiler’s installation manual for wiring diagrams. The Single-wall Indirect is supplied with an aquastat temperature control. This aquastat must be installed in the aquastat well location of the water heater. Refer to Figure 4. Remove the cover and loosen the clamping screws. Insert

the aquastat capillary bulb to the well bottom as shown and screw the aquastat clamp securely in the well groove. The aquastat acts as a thermostat for zone control and should be wired accordingly. Refer to the boiler or zone control manufacturer’s instructions if any additional wiring is required. The control is factory set at 120°F and care should be made to not rotate this dial while wiring the control. Once electrical connections are complete, secure the aquastat cover back in place. AT NO TIME SHOULD WATER

HEATER OPERATION TAKE PLACE WITHOUT THE COVER ON THE CONTROL.

WARNING

Water heaters are heat-producing appliances. To avoid damage or injury there must be no materials stored against the water heater, and proper care must be taken to avoid unnecessary contact (especially by children) with the water heater. UNDER NO CIRCUMSTANCES SHALL FLAMMABLE MATERIALS, SUCH AS GASOLINE OR PAINT THINNER BE USED OR STORED IN THE VICINITY OF THE WATER HEATER OR IN ANY LOCATION FROM WHICH FUMES COULD REACH THE WATER HEATER.

Installation or service of this water heater requires ability equivalent to that of a licensed tradesman in the field involved. Plumbing and electrical work are required.

OPERATING INSTRUCTIONS

SYSTEM START-UP

Follow boiler installation instructions to place boiler in operation.

SEQUENCE OF OPERATIONS

1.Aquastat senses stored water temperature drops below desired setting.

a.Domestic hot water priority only: Normally closed contacts open to interrupt space heating.
