General Safety Precautions

Be sure to read and understand the entire Use & Care Manual before attempting to install or to operate this electric boiler. Pay particular attention to the following General Safety Precautions. Failure to follow these warnings could cause property damage, bodily injury or death. Should you have any problems understanding the instructions in this manual, STOP, and get help from a qualified installer or technician.

Section 2: Introduction

WARNING

The important safeguards and instructions appearing in this manual are not meant to cover all possible conditions and situations that may occur. It should be understood that common sense, caution and care are factors which cannot be built into every product. They are the responsibility of the person(s) caring for and operating the unit.

2.1 LOCAL INSTALLATION REGULATIONS

This electric boiler must be installed in accordance with these instructions and in conformity with local codes, or in the absence of local codes, with the National Plumbing Code and the National Electric Code current edition. In any case where instructions in this manual differ from local or national codes, the local or national codes take precedence.

2.2 CORROSIVE ATMOSPHERE

The electric boiler should not be located near an air vent containing a corrosive atmosphere or high humidity. The limited warranty is void when the failure of the electric boiler is due to a corrosive atmosphere.

2.3 INSPECT SHIPMENT

Inspect the electric boiler for possible shipping damage. The manufacturer’s responsibility ceases upon delivery of goods to the carrier in good condition. Consignee must file any claims for damage, shortage in shipments, or nondelivery immediately against carrier.

2.4 CHECK LIST

Please check the identification tag on the unit to make sure you have the right model.

List of components shipped with the unit :

• Pressure relief valve set at 30 PSI.

• Drain valve.

• Tridicator (temperature & pressure

gage).

CAUTION

The electric boiler should not be located in an area where leakage of the tank or water connections will result in damage to the adjacent area or to lower floors of the structure. When such areas cannot be avoided, a suitable drain pan or nonflammable catch pan, adequately drained, must be installed under the boiler. The pan must be connected to a drain. NOTE: Auxiliary catch pan MUST conform to local codes.

DTH Electric Boilers USE & CARE MANUAL (Revision November/05), Page 4.

Section 3: Installation

WARNING

The manufacturer’s warranty does not cover any damage or defect caused by installation, or attachment, or use of any special attachment other than those authorized by the manufacturer into, onto, or in conjunction with the boiler. The use of such unauthorized devices may shorten the life of the boiler may endanger life and property. The manufacturer disclaims any responsibility for such loss or injury resulting from the use of such unauthorized devices

3.1 SECURITY CONSIDERATIONS

Domestic and commercial installations have a maximum design operating pressure limited to 30 psi (207 kPa) by a safety relief valve.

Boiler maximum operating temperature is 190°F by design. This boiler is designed to be used

only in a hot water heating system.

The heat transfer medium must be water or other non-toxic fluid having a toxicity rating or class of 1, as listed in clinical Toxicology of Commercial products, 5

3.2 LOCATION

The electric boiler should be installed in a clean, dry location. Long hot water lines should be insulated to conserve water and energy. The electric boiler and water lines should be protected from exposure to freezing temperatures.

The electric boiler must be installed horizontally, directly on the wall. Use the wall mounting brackets to make the unit level. The wall mounting brackets are held by four 5/16’’ lag screws. The openings are located at 16’’ intervals (i.e. standard stud spacing). When the first bracket is installed you can hang the boiler on the wall (see figure 1). The lag screws must be suitably anchored to safely support the weight of the boiler including water content, piping and wiring.

CAUTION

edition

The electric boiler must be located or protected so as not to be subject to physical damage, for example, by moving vehicles, area flooding, etc. All models can be installed on combustible floors and in alcoves. Ambient temperature must not exceed 80°F or 27°C.

3.3 CLEARANCE

Minimum clearances for adequate inspection and servicing are listed in the following table:

Table 4: Boiler clearance

Left side 16 inches

Right side 6 inches

Top & Bottom of the boiler 6 inches

Front side of the boiler 24 inches

Back side of the boiler 0 inch

3.4 PIPING

The recommended piping arrangement is shown in figures 2, 3, 4 and 5, including the pump, expansion tank, drain valve, pressure relief valve, air vent, flow check valve and pressuretemperature gauge. Details about each item follow.

3.4.1 Boiler connections

This electric boiler may be connected individually or in parallel with other boilers. If two or more boilers are connected, the “reversereturn piping” method (whereby the boiler with the first return inlet also has the last supply outlet and so forth until the last return inlet corresponds to the first supply outlet) should be used to connect the boilers in parallel, to ensure an equal water flow rate through each boiler.

The BOILER WATER SUPPLY, located on the top side, and the BOILER WATER RETURN, located on the bottom side of the boiler are steel pipes (male NPT threaded connection) where supply and return line connections are to be made.

Installing a union is recommended on the boiler water supply and return lines to facilitate boiler disconnection for servicing.

Dielectric unions are required for protection of the boiler and piping if dissimilar pipe material such as galvanized steel and copper are present.

DTH Electric Boilers USE & CARE MANUAL (Revision November/05), Page 5.

Use only clean pipe for boiler water lines. Local codes or regulations shall govern the exact type of material to be used.

Insulate all pipes containing hot water, especially in unheated areas.

Install shutoff (ball) valves for servicing convenience. Thermometer(s) should be installed on the boiler water supply and return lines.

Cap or plug unused connections on the boiler. Do not cap the pressure relief valve on the boiler since it will damage and shorten the life of the boiler and may endanger life and property.

3.4.2 Flow check valve

If the heating system is pipe to use only a single pump, then to minimize flow by gravity & heat loss during non-draw periods, a flow check

must

be installed.

3.4.3 Pressure relief valve

An automatic pressure relief valve must be installed during boiler setup. The pressure rating of the relief valve must not exceed 30 psi. The safety relief valve must meet the requirements of the ASME Boiler and Pressure Vessel Code and limit the maximum operating boiler pressure. It is a safety device, not an operating control.

The BTU per hour rating of the relief valve must equal or exceed the BTU per hour input of the boiler(s) or heat source(s) as marked on the boiler(s) rating plate.

Connect the outlet of the relief valve to a discharge line with its lower tip at most 6” above a floor drain, well clear of any live electrical parts. The discharge line must pitch downward from the valve to allow complete draining by gravity of the relief valve and discharge line, and be of a diameter no smaller than that of the valve outlet. The tip of the discharge line should not be threaded or concealed and should be protected from freezing. No valve of any type, restriction or reducer coupling should be installed on the discharge line. Local codes shall govern the installation of relief valves.

3.4.4 Piping system pressurization: expansion tank

Pressure control devices within the system ensure that each component operates within minimum and maximum allowable pressures and maintain minimum pressure for all normal operating temperatures. They also allow air bleeding, prevent cavitation at the pump inlet and prevent water from boiling within the system; all this is accomplished with minimal addition of new water.

The increase in boiler water volume resulting from higher temperature is stored in the expansion tank during periods of high operating temperature and is returned to the system when the temperature decreases.

The expansion tank must be able to store the required volume of boiler water during maximum design operating temperature without exceeding the maximum allowable operating pressure, and to maintain the required minimum pressure when the system is cold. Contact your installing contractor, plumbing supply house, or local plumbing inspector for assistance. The point where the expansion tank is connected should be carefully selected to avoid the possibility that normal operation of automatic check or manual valves will isolate the tank from a hot boiler or any part of the system. Precharged diaphragm expansion tanks are preferable to air control (see section 3.4.6).

These tanks incorporate a balloon-like bladder or diaphragm. It is inflated, prior to filling the system, to a pressure equal to the setting of the water pressure makeup regulator.

The expansion tank should be located on the suction or intake side of the pump. The pump can be located either just upstream or just downstream from the boiler.

3.4.5 Water pressure makeup regulator

Make-up systems must be employed as required by codes. An automatic fill valve must be used with a backflow preventer as required, to maintain minimum system pressure by supplying water to make up for leakage.

3.4.6 Air bleeder

Oxygen should be excluded from the system to prevent corrosion. As hinted at in section 3.4.4,

DTH Electric Boilers USE & CARE MANUAL (Revision November/05), Page 6.

this precludes the use of air in direct contact with the boiler water as a pressurization means.

Installation of manual or automatic air vent devices prevents air from accumulating in the system. Air vents should be installed at all high points to remove trapped air during initial setup and to ensure that the system is tight. Regularly purge the air out of the system while taking care to avoid personal injuries or property damage caused by hot boiler water spray.

3.4.7 Circulator zoning recommendations

The preferred location of the circulator pump for each zone is on the boiler supply side, with the expansion tank between the boiler and the pump.

A flow check valve must be installed in each zone, preferably on the outlet side of each circulator pump, to prevent water flow to other zones where no heat is required.

3.4.8 Zone valve zoning recommandations

The preferred location of the circulator pump is on the boiler supply side, with the expansion tank between the boiler and the circulator. Use zone valves with low pressure drop.

3.4.9 Pump & pipe sizing

3.4.9.1 Boiler water temperature drop (BWTD) through the heating loop

A simplified design method based on a 20°F temperature drop (BWTD) between boiler outlet and inlet is commonly used. Although such a method is widely used and generates satisfactory system performance when applied properly, it does not determine the system operating point. The pipe size is often uneconomically large, and the actual system flow rate is likely to be much higher than intended. Such design methods seldom consider temperature drops higher than 20°F, which results in overdesign.

Another method by which the boiler water temperature drop (BWTD) could be calculated is to assume a constant supply boiler water temperature minus the return boiler water temperature. For example a boiler might have a return temperature of 140 °F. Assuming a constant supply boiler temperature of 180 °F, the BWTD would be 40 °F ( = 180 °F – 140 °F).

Second example: If the boiler water has a return temperature of 120 °F and the boiler supply is at 140 °F, then the temperature drop is 20 °F (=140 °F – 120 °F).

The following table suggests temperature drops (BWTD) to be used in calculating the pump flow rate.

3.4.9.2 Pump flow rate calculation

The boiler output rating must correspond to the calculated heating load or be within the sizing guide recommendations. Use the equation below to calculate the pump flow rate.

Pump flow rate = Boiler output ÷ BWTD ÷ 500

• Pump flow rate is express in U.S. gallons per minute or GPM.

• The Boiler output ( in net BTU per hour) is the maximum heat to be transferred through the heating loop to meet the heating load.

• BWTD is the boiler water temperature drop

For example, a 24KW electric boiler has a rated output of 81,888 BTU per hour. The system is designed for a temperature drop (BWTD) of 20°F.

Pump flow rate = 81,888 ÷ 20 ÷ 500 = 8,2 GPM.

3.4.9.3 Pipe sizing criteria

Proper selection of pipe size is important to efficient system operation. A large pipe size results in lower friction losses and may allow the selection of smaller, more economical pump. The increased pipe size, however, costs more initially and must be balanced against the cost savings realized be smaller pump. Likewise, small pipe costs less initially but must be balanced against the increased operating cost of pumping water through a system with high friction losses. An economical balance should be reached between pump size, operating costs, and pipe diameter.

The ASHRAE fundamentals handbook states the general range of pipe friction loss used for the design of hydraulic systems and upper limits of water velocity in piping.

A variety of upper limits of water velocity and/or pressure drop in piping and piping systems are used. One recommendation places a velocity limit of 4 feet per second for 2 inch pipe and smaller, and a pressure drop limit of 4 feet of water per hundred feet for piping over 2 inches. These limitations are imposed either to control the levels of pipe and valve noise, erosion and water hammer pressure or for economic reasons.

Please note that in the smaller pipe sizes, this velocity limit permits the use of friction loss rates higher than 4 feet per 100 feet.

Fluid velocity should be above 1-1/2 to 2 feet per second in order to carry entrained air along to a high point in the system where it can be purged.

It is generally accepted that if proper air control is provided to eliminate air and turbulence in the system, the maximum flow rate can be established by a piping friction loss rate of 4 feet of water per 100 feet. This allows velocities greater than 4 feet per second in pipe sizes 2 inches and larger.

As piping ages, friction losses increase. It is recommended that for most commercial design purposes a safety factor of 10 to 15 % be added to the values in the tables.

What is a “foot of water”? A column of water at 60°F, 5 feet tall, creates a constant pressure of 5 feet of water at the bottom of the column. If the water column is 2.31 feet tall, the mass of water creates a constant pressure (head) of one (1) psi (pound per square inch). Pressure losses are expressed either in “feet of water” or in psi. Pump manufacturers usually prefer feet of water units.

3.4.9.4 Pump or circulator selection

Performance characteristics of centrifugal pumps are described by pump curves, which plot flow versus head or pressure together with other information such as efficiency and power. Consult the manufacturer’s pump curves to select the proper model or ask your pump dealer or your HVAC wholesaler for a recommendation.

3.5 ELECTRIC POWER SUPPLY

Wiring must conform to the National Electrical Code and to state or local code requirements.

The electric boiler must be electrically grounded in accordance with local codes, or, in the absence of local codes, with the National Electrical Code.

3.5.1 240Vac models

Wiring must be from a 120/240 Volt (single phase, 60 Hz) circuit protected by a properly sized breaker. Wire gage (3 wires, ground) must be properly sized. Consult the boiler rating plate to select the proper breaker and wire gage

DTH Electric Boilers USE & CARE MANUAL (Revision November/05), Page 8.

3.5.2 600Vac models

Line wiring must be from a 600 Volt ( 3 phase, 60 Hz) circuit protected by a properly sized breaker. Wire gage (3 wires, ground) must be properly sized. Consult the boiler rating plate to select the proper breaker and wire gage.

3.6 PUMP POWER SUPPLY

3.6.1 240Vac models

Connect only a 120 Vac, 9 amp. (maximum) pump to terminals C and C on the electric pannel. Do not use a 600 Vac pump or one drawing more than 9 amps. The logic circuit is designed to activate the circulator based only on demand by the thermostat after a time delay.

3.6.2 600Vac models

Use a relay (Honeywell #RA-889, RA-89A) or the secondary contact of a zone valve (if the heating system is zoned using 4-wire zone valves). When a thermostat calls for heat: the relay will power either the boiler pump or the zone valve (the zone valve will power the boiler pump upon opening fully). See figure 6 for more details.

If the heating system is designed to use only a single pump, then to minimize flow by gravity and heat loss during non-draw periods, a flow

check must

be installed.

3.7 CONNECTING THE THERMOSTAT

3.7.1 For 240Vac model

3.7.1.1 Single heating zone Connect a low voltage thermostat to terminals T and T on the electric panel (DO NOT apply any power to these terminals!).

3.7.1.2 Multiple heating zones Connect the zone valve end switch to terminals T and T on the electric pannel (DO NOT apply

any power to these terminals!). See figure 6.

3.7.2 For 600Vac model

3.7.2.1 Single heating zone Connect the low voltage thermostat to a relay (Honeywell #RA-889, RA-89A). See figure 6.

3.7.2.2 Multiple heating zones

Zone valve zoning Connect the low voltage thermostat to the zone valve. Components must be wired to ensure that only the zone valve corresponding to the zone calling for heat is actuated and that the circulator is powered on a demand from any zone.The transformer used to power the zone valves must be sized for the load represented by all zone valves in the heating system. See figure 6.

Circulator zoning Connect the low voltage thermostat to the relay (Honeywell #RA-889, RA-89A). Components must be wired to ensure that only the circulator corresponding to the zone calling for heat is actuated. See figure 6.

DTH Electric Boilers USE & CARE MANUAL (Revision November/05), Page 9.

3.8 CBE-EM DUAL ENERGY INSTALLATION

In order to obtain a special rate from your electric utility for residential use, your GTH boiler can be hooked-up to an existing oil heater. Contact your electric utility to find out if your property is eligible for such rates and how to register for them. For installations instructions, refer to figure 12, 13 and 14.

The CBE-EM dual-energy control (an available option, three-way, motorized valve (1’’ NPT F standard) included) is specially designed to electric utility standards. The CBE-EM control selects the least expensive energy source based on outside temperature, user choice or a signal from your utility.

The CBE-EM dual-energy control will start up the oil burner upon receiving the appropriate signal, even if the thermostat in the house is not calling for heat. It will shut off when the temperature in the boiler reaches its target on the Limit Control. It is for this reason that the piping requires an anti-gravity valve (flow check valve) or motorized zone valves.

A three-way, motorized valve (1’’ NPT F standard) will direct the water flow either to the oil-fired heater or to your DTH electric boiler, depending on the signal received. This way, your oil heater will cool down and eliminate any energy loss, either through the chimney or by way of conduction in the boiler room.

DTH Electric Boilers USE & CARE MANUAL (Revision November/05), Page 10.

Section 4: Operation

SAFETY PRECAUTIONS !

Before operating this boiler, be sure to read and follow these instructions, as well as the warnings printed in this manual. Failure to do so can result in unsafe operation of the boiler resulting in property damage, bodily injury, or death. Should you have any problems reading, following or difficulty in understanding the instructions in this manual, STOP, and get help from a qualified person.

Do not turn on the boiler unless it is filled with water. Do not turn on the boiler if the cold water supply shut-off valve is closed.

After the boiler has been plumbed and wired, it is now ready to be set for automatic operation.

4.1 FILLING THE BOILER

Open the shutoff valve (and on a zone valve system, manually open zone valve) on the supply piping from the boiler.

Open cold water supply valve (fill or makeup water valve) to boiler.

To let the air out of the boiler tank during the fill process open the relief valve on top of the boiler.

Leave all shutoff valves open. Return zone valves to automatic operation.

Check system for leaks and repair. Purge air from the remaining zones, if

necessary. Check boiler pressure gage reading. 15 to 20 psi is normal for most installations.

4.2 AQUASTAT ADJUSTMENT

After the system has been manually purged of air, and all components (valves, vents, controllers) have been set properly, the boiler can be started. Never operate this boiler until this has been done.

Safety and energy conservation are factors to be considered when setting the boiler water temperature using the aquastats. The most energy-efficient operation will result when the temperature setting of each aquastat is the

lowest that satisfies the heating needs.

refer to table 5 for more details.

Each aquastat controls one stage (in the 240V model each electric element has it own aquastat; in the 600V model there is one aquastat per 3 elements). Set the temperature on the aquastat using the knob graduated in degrees Celsius and Fahrenheit.

Set the temperature on the first aquastat to the highest supply temperature required by the heating system.

Please

Set the temperature on the second aquastat from 1°F to 20°F below the setpoint of the first aquastat. Usually 5°F below the setpoint of the first aquastat is adequate if the boiler water temperature drop is 20°F.

Proceed in a similar manner for the 3rd, 4th and any supplementary aquastats, lowering the set point by 5°F each time.The elements will thus be activated (and de-activated) in the number required by the set points and the drop (or rise) in boiler water temperature.

On initial start up (on the first day of the heating season) with a cold tank, a considerable amount of time may be required for the tank to reach desired temperature. Check the temperature on the boiler temperature gage.

Adjust the boiler aquastats as needed. Note that setting the aquastat to a lower setting will not have an immediate effect. The stored boiler water heat will first have to be consumed. Additional checks of the water temperature should follow completion of a cycle. Further adjustments may be necessary as you use your boiler and space heating system.

Note: The maximum setting for the boiler water supply to the heating system is 190°F.

DTH Electric Boilers USE & CARE MANUAL (Revision November/05), Page 11.

4.3 STARTUP PROCEDURE

1. Fill the boiler as described in section

4.1.

2. Set the boiler operating temperature as described in section 4.2.

3. Turn down all room thermostats under room temperature

4. Turn on the boiler power breakers and switch.

5. The main contactor should close and all elements should be in operation. Pilot lights should be on.

6. Temperature inside the boiler should increase. Elements and pilot lights should turn off one by one as they reach their set point.

7. When all elements are off, turn up all room thermostats above room temperature.

8. The circulator should start up after a time delay.

9. The elements should turn on in sequence as the boiler water temperature drops below the aquastat set points. This could take many minutes.

10. The circulator stays on for as long as there is a demand for heating. When the circulator turns off,

11. Temperature inside the boiler should increase. Elements and pilot lights should turn off one by one at they reach their aquastat set point.

In this way, the power drawn by the boiler depends on the actual heating load of the building. If you need only one stage to heat your home, only one will be turned on; if you need two stages, two will be turned on. Excessive cycling and wear and tear of electric components will be avoided, thus increasing their life reducing heating cost.

DTH Electric Boilers USE & CARE MANUAL (Revision November/05), Page 12.

Section 5: Maintenance

Properly maintained, your boiler will provide years of dependable, trouble free service. It is recommended that a regular routine maintenance program be established and followed by the user. Components are subject to eventual failure that requires service. Failure to use the correct procedures or parts in these circumstances may make the unit unsafe or reduce the life of the boiler.

The owner should have the following inspection and maintenance procedures performed:

5.1 BOILER WATER PIPING:

 Yearly visual inspection.

Check all piping for signs of leakage near joints, unions and shut-off valves. Repair as needed.

5.2 PRESSURE RELIEF VALVE ON TOP OF BOILER:

 Monthly inspection.

Must be manually operated to ensure safe and proper operation. By opening the pressure relief valve, the air trapped inside the heater tank is purged.

Make sure that the discharged water is directed to a suitable drain or other collection device, and will not spray onto anyone. Use the lever on the pressure relief valve to open. A steady discharge of hot water should occur. After releasing this lever the safety relief valve should close and fully shut off this flow. If the pressure relief valve does not function properly, it must be replaced with the same model or its equivalent. Do not plug the outlet of this valve if a dripping condition occurs.

5.3 BOILER PURGE

 Yearly.

It is recommended that the boiler be purged annually, in order to eliminate sediment and sludge which may have accumulated at the bottom of the boiler and covered the heating elements.

Procedure

1. Let the boiler cool down

2. Close the maintenance valves connected to the boiler inlet and outlet. N.B.: It is not recommended to drain the water from the whole heating system.

3. Hook-up a garden hose to the drain valve and place it close to a floor drain.

4. Open the purge valve until the water comes out clean and clear

5. Close the valve

It is recommended to perform a visual inspection of the boiler electrical compartment annually, during the heating season, to ensure it is watertight and that there are no signs of component or wiring overheating. Repair as soon as possible if necessary. Defective components should always be replaced with the Original Manufacturer’s parts.

The manufacturer’s warranties DO NOT cover tank failure due to improper installation or maintenance. If the pressure relief valve on the heater discharges periodically, this may be due to thermal expansion. Immediately call a qualified service technician to inspect and to remedy as needed.

NOTE: To prevent premature tank failure, the air trapped inside the tank must be purged periodically. Use the safety relief valve on top of the tank to perform this task.

Before manually operating the relief valve, make certain no one will be sprayed with the hot water released by its opening. The water may be hot enough to create a SCALD hazard. The water released should be directed to a suitable drain to prevent injury or damage.
