IMPORTANT STEPS AND DECISIONS REQUIRED BEFORE INSTALLATION

M THIS PRODUCT MUST BE INSTALLED AND

MAINTAINED BY A LICENSED PROFESSIONAL. IN ADDITION TO THE INSTRUCTIONS IN THIS MANUAL, FOLLOW ALL APPLICABLE LOCAL AND STATE CODES OR IN THE ABSENCE OF SUCH CODES, THE CURRENT EDITIONS OF THE NATIONAL PLUMBING CODE AND THE NATIONAL ELECTRIC CODE.

M DRIP PAN AND DRAIN: This appliance should not

be installed in an area where leakage of the tank or connections can result in damage to the area adjacent to the appliance or to lower floors of the structure. When such locations cannot be avoided, a suitable drain pan, adequately drained and kept clear, must be installed under the appliance.

M CAUTION: Determine whether your water is corrosive

or acidic, and that there are no suspended solids, toxic or other substances or abnormally high chlorine levels in the water that could damage or affect the BOILERMATE

MODELS. Glycol is a hazardous substance. To avoid seepage or leakage of glycol to surfaces where humans or animals can ingest it, use glycol only in double-walled units, so that any leaks will most likely be released to the atmosphere. However, a leak to a surface area may still occur, so any use of glycol must be monitored closely and humans and animals should be protected from contact with the unit.

or other space heating units or elements. Any contaminants in the baseboard units will contaminate the potable water in the BOILERMATE® and also adversely affect its performance.

M Wiring Options. Select either a Non-Priority or Priority

System:

Two options are available when wiring the controls of the BOILERMATE distribution elements).

1. Non-Priority System - The controls of the BOILERMATE zone with a standard zone valve or a separate circulator dedicated to the BOILERMATE

NOTICE: In this non-priority option, the BOILERMATE will be supplied just as another zone. This means that if all space heating zones call for hot boiler water at the same

or the rest of your plumbing system.

USE GLYCOL ONLY WITH DOUBLE-WALLED HEAT EXCHANGER

Do not connect the BOILERMATE® domestic supply with baseboard

in the space heating system (boiler and

must be wired as a separate heating

“zone”.

time, the BOILERMATE

may not be supplied with enough

hot boiler water to “recover” adequately. The delivery of domestic hot water will be diminished. In many, but not all cases, this is not a problem because the routine oversizing of boiler output is adequate for both loads.

2. Priority System - Under this wiring option the BOILERMATE

will be supplied before space heating.

In limited circumstances, space

heating can be lost in the home in this priority mode. Any demand for space heating is postponed until the BOILERMATE

has reached its set temperature. This delay in supplying the space heating zones is usually not noticed by the inhabitants of the living spaces. However, in the event of certain malfunctions such as circulator or thermostat failure, space heating could be delayed indefinitely. If undetected and uncorrected, freezing damage to piping could result.

M Select Circulator versus Zone Valve

The flow of hot boiler water to the BOILERMATE

can

be controlled with either a motorized zone valve or a circulator.

1. Separate circulator. The recommended way to provide adequate flow through the BOILERMATE

heat exchanger is to use a separate dedicated circulator with a minimum flow rate of 5 gpm. This option may be used even though the heating system utilizes zone valves.

2. Zone valve (system flow of 4-8 gpm). If a zone valve is to be used, a minimum flow rate of 5 gpm with all zones in use is required. A full-port zone valve should be used.

M All installations require a low-water cut-off or automatic fill

valve on your boiler system to reduce the risk of boiler water

loss.

M Steam boiler installations require a low-water cut-off which

is also required by most codes.

M Installation of a vacuum breaker is required to prevent

damage to the BOILERMATE

when drained. There must be no valves installed between the vacuum breaker and BOILEMATE®.

DOMESTIC WATER PIPING

1. Thread the included 3/4” brass tee onto the pipe marked COLD WATER.

2. Screw the

tee.

3. Connect the cold water supply to the remaining port on the brass tee.

4. Temporarily attach the top tee fitting (with o-ring face seal) to the union nut on top of the tank. Test fit the piping near the tee before soldering. Remove the tee before soldering connections to avoid damage to the top o-ring seal or plastic liner.

Note: Do not solder piping within 24 inches of the top tee fitting while attached to the tank.

5. Make an 8-inch “heat trap” as shown in the diagram. This will reduce standby losses from heat migrating up the piping. Continue this line to the domestic hot water system.

6. Install the included T&P relief valve on the top port of the top tee connection. Plumb a blowdown tube to within 6 inches of a floor drain or as directed by plumbing code.

7. When all domestic water piping is complete, open the cold water supply and allow some water to enter the tank. Look and listen for signs of leaks and repair as necessary before continuing.

The Smart Control™ incorporates all the switching and temperature control functions necessary to control the BoilerMate™. The diagram below shows internal wiring and the associated functions.

After wiring is complete, insert the white thermistor (sensor) plug into the receptacle at the base of the Smart Control™. Select the plug marked CIRCULATOR or ZONE VALVE based on the application. Zone valves can be slow actuating. Therefore, the zone valve sensor contains a built-in temperature offset to account for the time it takes the zone valve to fully close. This results in potable water temperature that is representative of the Smart Control™ temperature set point. This is why it is important to install the correct sensor into the Smart Control™. See Page 2 for information regarding the selection of a circulator or zone valve.

WATER SENSOR INSTALLATION (IF EQUIPPED)

The Smart Control™ features an error code designed to alert the user to the presence of water on the oor. This is useful to warn of a leaking boiler, water heater, etc., or to alert the owner to a leak in the basement. If equipped with the optional water sensor, follow the installation instructions below:

1. If the sensor will be used to detect a water heater leak, the proper placement is in a drip pan as required in the warning section of this manual. This will both protect the surrounding surfaces from water damage and provide sufficient water depth to activate the alarm. The sensor will function with either side placed toward the floor.

2. If the sensor will be used to detect another potential leak source, such as basement flooding, the sensor must be placed on a flat section of floor in an area where water will first collect. If the level cannot reach 1/32”, the alarm feature may not function. Do not place in a high-traffic area where the sensor could be stepped on or moved. The sensor will function with either side placed toward the floor.

3. After placing the sensor in the appropriate location, plug the water sensor connector into the Smart Control™.

4. Upon wiring the Smart Control™, test the sensor by either immersing it in water or inserting a coin between the two electrodes. The Smart Control should display Er4 and sound an alarm. The error and alarm should disappear when the sensor is dried or the coin is removed. Perform this test during the annual inspection of the BoilerMate in an area known to flood.

5. This sensor should not be the primary means of leak detection.

11. STARTUP PROCEDURE FOR ALL MODELS

1. PURGE HEAT EXCHANGER: The heat exchanger should be free of large air pockets to allow the circulator to operate properly. Using the diagram below as a guide, isolate the boiler return line and flush the loop until large air pockets are purged. After this, the air elimination equipment will collect smaller air bubbles to maximize efficiency.

2. FILL TANK: Open the hot water fixture furthest from the heater. Open the cold water supply and allow the water to run until air stops emerging. Until all air is purged from the hot water system, air pockets may appear at any hot water fixture. This is considered normal and will clear as hot water is used.

3. START HEATER: Turn power on to the unit. Smart Control™ models come pre-set at 120°F for safety. Dial units should have the knob rotated to the 120°F mark. The circulator and boiler should start momentarily.

If not, check wiring and consult the troubleshooting section in this manual.

4. CHECK OPERATION: The BoilerMate heat. Depending upon the size of the BoilerMate, output of the boiler and the space heating load, the unit should typically reach set temperature within 15 to 60 minutes. If heating does not occur, consult the troubleshooting section in this manual. Note: Large heaters coupled with small boilers may exceed this time period upon initial startup.

5. SET TEMPERATURE: The BoilerMate be set to the minimum temperature consistent with the user’s needs. This maximizes efficiency and reduces scald potential.

12. SETTING THE SMART CONTROL™

The Smart Control™ incorporates multiple features that increase hot water performance and efficiency. All settings are accessed via the MODE button. To change any setting, simply hold the MODE button then tap to cycle through the settings as outlined below.

GREEN LIGHT - CIRCULATOR INDICATOR

READOUT

DISPLAY

MODE SWITCH

• When power is applied to the unit, the display will show the setpoint temperature (default 120°F).

• Pressing and holding the MODE pushbutton once for 6 seconds will display

then 120°F. This is the water temperature setpoint. To raise or lower this temperature setpoint, press the s or t pushbutton. The temperature can be set between 90°F and 150°F. To shut the unit down, scroll below 90°F until 0°F is displayed. Shutting the unit down is benecial if the water heater will not be used for an extended period of time.

WARNING: Temperature settings above 120°F can create a scald hazard.

• Pressing the MODE pushbutton a second time will cause

to be displayed, and releasing the MODE pushbutton will cause 10°F to be displayed. This is the differential setpoint, a setpoint that determines how many degrees the water temperature is allowed to drop before the water heater activates. To change between the available 10°F and 5°F settings, press and release the s or t pushbutton.

• Pressing the MODE pushbutton a third time will cause

to be displayed, and releasing the MODE pushbutton will cause 0°F to be displayed. This is the post purge setpoint, a setpoint that allows the boiler to be shut off when the actual water temperature is a certain number of degrees below the setpoint temperature. Since the circulator continues to run, the post purge feature will remove excess heat from the boiler after the boiler shuts off. To change the post purge setpoint, press and release the s or t pushbutton to select 0°F, 4°F, or 8°F below setpoint temperature. NOTE: If the differential is set to 5°F, then the post purge setting will not be available and will automatically be set to 0°F. NOTE: When using the BoilerMate

on a zone valve application, the post

purge feature will not function.

• Pressing the MODE pushbutton a fourth time will cause Pri to be displayed, and releasing the MODE pushbutton will cause ‘y’ to be displayed. This is called the priority setting, a setting that allows the domestic hot water to reach the setpoint temperature before spatial heating is allowed to resume. To disable the ‘priority’ feature, press and release the s or t pushbutton until ‘n’ is displayed.

• Pressing the MODE pushbutton a fth time will cause

to be displayed, and releasing the MODE pushbutton will cause ‘41’ to be displayed. This is the tank volume in gallons. To change this volume, press and release the s or t pushbutton to select the proper tank size (26, 41, 60, 80, or 120 gallons).

• Pressing the MODE pushbutton a sixth time will cause

to be displayed, and releasing the MODE pushbutton will cause a

number to be displayed. This is a BTU heat transfer rate estimate in MBH. This is a diagnostic readout and cannot be changed.

• NOTE: Any changes made to the above settings will take effect after 10 seconds. This will be acknowledged by a display of . Thereafter, these changes will be the new control settings even in the event of a power outage.

• An approximation of the actual domestic water temperature in the tank can be displayed in °F by pressing the s pushbutton.

• One or more error messages will be displayed if abnormal operation occurs, and an audible alarm will sound for most error

messages. The audible alarm can be silenced by pressing the t pushbutton. An damaged thermistor (temperature sensor). Check and replace as necessary. An

message indicates an unplugged or

message appears when the stored water temperature exceeds 155°F. Contact your service person to correct the problem. An Er3 message indicates that the actual domestic water temperature did not reach the setpoint temperature after one hour of attempted heating. Contact your service person to correct the problem. For models equipped with a water sensor, an Er4 message indicates that a water puddle has been detected. Contact your service person to correct the problem.

Note: Smart Control

™

is to be used for indoor applications only. Do not operate the Smart Control™ unit outside

of the following ranges:

• Ambient temperature from 38°F to 125°F.

• Relative humidity ranging from 20% to 90% (non-condensing).

• Boiler load rating up to 15A resistive, 1/4hp inductive @120VAC.

• Circulator load rating up to 15A resistive, 1/4hp inductive @120VAC.

• Space heating load rating up to 8A @ 120VAC.

Note: For models equipped with a water sensor, the water sensor should be placed at on the oor in a low-trafc area. On a regular

basis, verify that the water sensor is functioning properly by placing the orange puck in a water puddle or inserting a coin between the two electrodes and listening for an audible alarm. This water sensor should not be the primary means of leak

detection. See water sensor installation page for more details.

Note: If setpoints were being adjusted when a power outage occurred, then recheck all set points after power has been restored.

15. CLEANING THE BOILERMATE HEAT EXCHANGER COIL

A diminished temperature difference between the boiler water entering and leaving the heat exchanger coil may indicate heat exchanger scale buildup. Water treatment equipment and proper maintenance will help to avoid this problem. To clean a scaled heat exchanger coil proceed as follows:

1. Shut off the cold water supply to the BoilerMate®.

2. Make a note of the temperature control setting on the BoilerMate®, then turn the unit off.

3. Relieve the water pressure in the tank by opening a hot water faucet. This will reduce the risk of scalding injury.

4. Remove the relief valve from the top of the BoilerMate®, taking care to avoid contact with the hot water, which may drain out of the plumbing.

5. Drain the BoilerMate® until the water within the tank is even with the top of the heat exchanger

- approximately 15 gallons for 41-gallons units and 5 gallons for 26-gallon units.

Do not over-drain the tank.

Improper thermostatic control could result during Step 6 and lead to damage to the BoilerMate®.

7. Set the temperature control to its highest setting and operate the unit until the control is satisfied. Note: Boiler may cycle on its high limit several times during this period. If the tank temperature setting has not been satisfied after 45 minutes of boiler operation, turn the BoilerMate® control off to stop boiler operation.

8. Allow heated solution to set in tank for 30 minutes, then drain tank completely using fitting and hose, as required.

9. Fill water tank with fresh, cold, conditioned water and drained completely at least two times or until drained water runs clear.

10. Reinstall the safety relief valve.

11. Open the cold water supply and fill the tank with water. Purge plumbing by operating all hot and cold water fixtures in the building.

12. Return the control to the setting noted in Step 2 and verify that the unit is functioning properly.

As an alternative to the above, the teat exchange may

be removed from the BoilerMate® and cleaned. A new gasket must be installed whenever the heat exchanger is removed.

6. Using a funnel, pour one gallon of nontoxic commercial phosphoric acid solution (commercial icemaking cleaning solution) into the water tank through the top opening. Be sure that the manufacturer’s directions and warnings are followed.

15. GENERAL SAFETY INFORMATION

SCALDING HAZARD. If the water

temperature is over 120°F, household members can suffer serious or fatal scalding and painful and permanent injury. • The Consumer Products Safety Commission recommends an initial setting of 120°F, but notes a slower response time of infants, aged, disabled and other persons increases the scalding hazard and may require lower settings. • Always check the water temperature before use, including washing, bathing or showering. • Temperature limiting valves are available from your plumbing supplier. A check valve must be installed in the boiler return line to prevent gravity flow through the heat exchanger. This can cause overheating and result in serious or fatal scalding.

SCALDING HAZARD. If the thermostat

is not working properly or if this product is not installed in accordance with the manual, water temperature can reach excessive levels that may cause serious or fatal scalding. After installation and any servicing of the unit, verify that the thermostat is working and firmly inserted in the thermostat well by following the thermostat testing instructions in the manual.

Failure to use the correct replacement parts may make your product unsafe.

CALIFORNIA PROPOSITION 65 WARNING! WARNING: This product

contains a chemical known by the State of California to cause cancer and birth defects or other reproductive harm. (California Installer/Contractor - California law requires that this notice be given to consumer/end user of this product.) For more information: www.amtrol.com/

prop65

In limited circumstances, space heating

can be lost in the home with unit utilizing priority mode. Any demand for space heating is postponed until the Boiler Mate® has reached its set temperature. This delay in supplying the space heating zones is usually not noticed by the inhabitants of the living spaces. However, in the event of certain malfunctions such as circulator or thermostat failure, space heating could be delayed indefinitely. If undetected and uncorrected, freezing damage to piping could result.

If a steel hydropneumatic tank is in

place, AMTROL® recommends replacing it with a properly sized EXTROL® expansion tank. Otherwise, significant heat transfer problems can occur by causing air to be trapped in the heat exchanger. If the boiler system has an EXTROL® or Radiant EXTROL® expansion tank and the boiler temperatures are being changed, resize the EXTROL® or Radiant EXTROL® expansion tank.

If installing on city water supply a

properly sized THERM-X-TROL® is required with the BoilerMate® and should be installed as set fo rth in the THERM-X-TROL® product installation manual. Contact your water supplier or local plumbing inspector for additional information.

Prevent pressure build-up in any existing

internal tankless coil. Do not plug incoming or outgoing tappings in the internal tankless coil plate. Leave the coil in the boiler and leave system connections open, to prevent pressure build-up.

Electrocution hazard. The BoilerMate®

must be electrically grounded. Electrical supply must come from the boiler side of boiler’s emergency shut-off switch in order to prevent unsafe boiler operation.

Note: Inspect for shipping damage and notify freight carrier or store where purchased immediately if damage present. To avoid risk of personal injury and property damage, if the product appears to be malfunctioning or shows signs of corrosion, call a qualified professional immediately. Current copies of the Product manual can be viewed at www.amtrol. com. Use proper safety equipment when installing.

EXPLOSION HAZARD. The pressure of

the heat transfer medium must be limited to a maximum of 30 psig by an approved safety or relief valve on your boiler. The BoilerMate 150 psig maximum by the installation of a temperature and pressure relief valve (included). The relief tube must be plumbed to a suitable drain per code. No reducing coupling or other restriction may be placed in this line.

This Product, like most Products under

pressure, may over time corrode, weaken and burst or explode, causing serious or fatal injury, leaking or flooding and/or property damage. To minimize risk, a licensed professional must install and periodically inspect and service the Product. A drip pan connected to an adequate drain must be installed if leaking or flooding could cause property damage. Do not locate in an area where leaking could cause property damage.

EXPLOSION OR RUPTURE HAZARD.

A relief valve must be installed to prevent pressure in excess of local code requirement or maximum working pressure designated in the Product Manual, whichever is less. Do not expose Product to freezing temperatures or temperatures in excess of the maximum rated operating temperature.

If not installed by the boiler manufacturer,

install a low water cut-off or pressure reducing valve on your boiler so that leaking will not result in a dry boiler which if the boiler continues to fire, will cause an explosion hazard.

This unit must be installed as a separate

heating zone. Do not connect this unit to an existing heating zone or feed boiler water directly through the coil as dangerous over-heating will result.

Do not drain this appliance before

shutting off the supply valve and opening the relief valve or another downstream fixture, as it will damage this unit. A vacuum breaker should be installed to avoid damaging the liner. Damage to the unit and leakage can occur if a vacuum breaker is not installed.

USE GLYCOL ONLY WITH

DO U B L E-WA L L ED HEA T EXCHANGER MODELS. Avoid risk of ingesting a toxic glycol

fluid. The heat transfer medium should be water. If glycol must be used, it should only be used with double-walled heat exchangers and closely moitored for leakage.

pressure must be limited to

Chlorine Aggressive Water: The water

quality can significantly influence the life of this Product. You should test for corrosive elements, acidity, total solids and other relevant contaminants, including chlorine and treat your water appropriately to insure satisfactory performance and prevent premature failure.
