PART 1 – GENERAL SAFETY INFORMATION A. PRECAUTIONS This boiler is for indoor installations only. Clearance to combustible materials: 6” top, bottom, and sides, 0” back. Left side has all boiler mechanical connections. Front must have room for service, 24” recommended. (A combustible door or removable panel is acceptable front clearance.) This boiler has been approved for closet installation. Do not install this boiler directly on carpeting. For installation on combustible flooring.
Do not use “homemade cures” or “boiler patent medicines”. Substantial property damage, damage to boiler, and/or serious personal injury may result. Continual fresh make-up water will reduce boiler life. Mineral buildup in the heat exchanger reduces heat transfer, overheats the stainless steel heat exchanger, and causes failure. Addition of oxygen from make-up water can cause internal corrosion in system components. Leaks in the boiler or piping must be repaired at once. F.
PART 2 – BEFORE YOU START A.
Condensation Collection System – This boiler is a high efficiency boiler, and will produce condensate. The collection system has a float switch which monitors the condensation level and prevents condensation from backing up into the combustion system. Inside the collection system there is a built in trap which seals the combustion system from the connected drain. This condensate should be neutralized to avoid damage to the drainage system or piping.
Never close existing ventilation openings The service life of the boiler’s exposed metallic surfaces, such as the casing, as well as internal surfaces, such as the heat exchanger, are directly influenced by proximity to damp and salty marine environments. In such areas, higher concentration levels of chlorides from sea spray coupled with relative humidity can lead to degradation of the heat exchanger and other boiler components.
Figure 1 – Required Clearances Space must be provided with combustion/ventilation air openings correctly sized for all other boilers located in the same space as the boiler. The boiler cover must be securely fastened to prevent it from drawing air from the mechanical room. This is particularly important if the boiler is in a room with other boilers. Failure to comply with the above warnings could result in substantial property damage, severe personal injury, or death.
SPECIFICATIONS AND DIMENSIONS Figure 2 – LP-387-K
D. RESIDENTIAL GARAGE, CLOSET, AND ALCOVE INSTALLATIONS Check with your local Authority Having Jurisdiction for requirements when installing boiler in a garage, closet, or alcove. Please read the entire manual before attempting installation. Failure to properly take factors such as boiler venting, piping, condensate removal, and wiring into account before installation could result in wasted time, money, and possible property damage and personal injury.
You must ensure that intake air will not contain any of the contaminants listed in Table 2. For example, do not pipe intake vent near a swimming pool. Avoid areas subject to exhaust fumes from laundry facilities. These areas always contain contaminants. Contaminated air will damage the boiler, resulting in possible substantial property damage, severe personal injury, or death. NOTE: DAMAGE TO THE BOILER CAUSED BY EXPOSURE TO CORROSIVE VAPORS IS NOT COVERED BY WARRANTY.
Figure 4 – Pallet with Mounting Bracket Affixed Figure 5 –Boiler Mounted to Bracket B. WALL MOUNTING CONSIDERATIONS These boilers are wall mounted. Use only the wall mounting instructions included in this manual. Ensure the wall that the boiler is intended to be mounted on is comprised of cement, brick, block, or wooden studs spaced 16” apart from center.
b. The provided mounting bracket must be mounted directly to the center of at least 2 studs using standard steel or stainless steel ¼” x 2 ½” lag bolts for all models. Be sure the bracket is level and mark the hole location of the bracket height and horizontal stud location. Ensure the marked holes are located in the center of the building frame (studs). c. For all EFT models, 2 ½” is the minimum lag bolt length if the bracket is directly on stud.
Never use dielectric unions or galvanized steel fittings when connecting to a stainless steel storage tank or boiler. Failure to follow this instruction can lead to premature failure of the boiler system. Such failures ARE NOT covered by warranty. Plumbing of this product should only be done by a qualified, licensed plumber in accordance with all local plumbing codes. The boiler may be connected to a storage tank to supply domestic hot water.
D. SYSTEM WATER PIPING METHODS EXPANSION TANK AND MAKE-UP WATER 1. Ensure that the expansion tank is designed and sized to correctly handle system water volume and temperature. For sizing information, refer to expansion tank manufacturer’s sizing guidelines or the latest ASHRAE expansion tank sizing standards. Expansion tanks must be sized according to total system volume. This includes all length of pipe, all fixtures, boilers, etc.
additional requirements. If the boiler supplies hot water to heating coils in air handler units, flow control valves or other devices must be installed to prevent gravity circulation of boiler water in the coils during the cooling cycle. Chilled water medium must be piped in parallel with, and isolated from, the boiler. Freeze protection for new or existing systems must use glycol that is specifically formulated for this purpose.

H. PIPING INSTALLATION This boiler should not be operated as a potable hot water heater. It should not be used as a direct hot water heating device. Basic steps are listed below that will guide you through the installation of the boiler. 1. Connect the system return marked “Boiler Return”. 2. Connect the system supply marked “Boiler Supply”. 3. Install a purge and balance valve or shut off valve and drain on the system return to purge air out of each zone. 4.
The chart below represents the various system design temperature rise through the boiler along with their respective flows and friction loss, which will aid in circulator selection. Table 5 – Boiler Flow Rates In addition, the heat exchanger has a minimum total water volume that must be taken into account when sizing the circulator. These minimum water volumes are listed in Table 6 below.
ACIDITY CONDUCTIVITY CHLORIDE IRON COPPER SODIUM HARDNESS 6 to 8 pH Less than 400 uS/cm at 25oC Less than 100 ppm Less than 0.5 mg/L Less than 0.1 mg/L Less than 20 mg/L Less than 7 Grains Table 8 – Water Quality Requirements Clean system to remove sediment* 1. You must thoroughly flush the system (without boiler connected) to remove sediment. The high-efficiency heat exchanger can be damaged by buildup or corrosion due to sediment. 2.
For installations that incorporate standing iron radiation and systems with manual vents at the high points, follow the previous section and, starting with the nearest manual air vent, open the vent until water flows out. Then close the vent. Repeat the procedure, working your way toward the furthest air vent. It may be necessary to install a basket strainer in an older system where larger amounts of sediment may be present. Annual cleaning of the strainer may be necessary.
PART 6 – VENTING, COMBUSTION AIR, AND CONDENSATE REMOVAL The boiler must be vented as detailed in this Venting Section. Ensure exhaust vent and intake piping complies with these instructions regarding vent system. Inspect finished exhaust vent and intake piping thoroughly to ensure all joints are well secured, airtight, and comply with all applicable code requirements, as well as with the instructions provided in this manual.
B. APPROVED MATERIALS FOR EXHAUST VENT AND INTAKE PIPE Item Exhaust vent or Intake pipe and fittings Pipe cement/primer APPROVED EXHAUST VENT AND INTAKE PIPE MATERIAL Standards for Installation in: Material United States Canada PVC schedule 40/80 ANSI/ASTM D1785 PP, CPVC, and PVC venting must be ULC-S636 Certified. PVC-DWV* ANSI/ASTM D2665* IPEX is an approved CPVC schedule 40/80 ANSI/ASTM F441 manufacturer in Canada, supplying vent material listed to Polypropylene ULCS636 ULC-S636.
You must not use “B” vent in an exhaust application. “B” vent is for intake applications ONLY. Using “B” vent in an exhaust application will result in serious injury or death. Figure 14 - NOTE: Drawing is meant to demonstrate system venting ONLY. D. EXHAUST VENT AND INTAKE PIPE LOCATION NOTE: SEE ADDITIONAL REQUIREMENTS FOR MASSACHUSETTS IN THE BACK OF THIS MANUAL. 1. Determine exhaust vent location: Total length of vent may not exceed the limits specified in Part 6.
The building owner is responsible for keeping the exhaust and intake terminations free of snow, ice, or other potential blockages, as well as scheduling routine maintenance. Failure to keep the vent piping terminations clear and properly maintain the boiler could result in property damage, severe personal injury, or death. For each floor containing bedroom(s), a carbon monoxide detector and alarm shall be placed in the living area outside the bedrooms, as well as in the room that houses the boiler.
1. Ensure all parts shown in Figure 15-1, Condensate Detail, are included with the condensate trap. If any parts are missing, DO NOT install the trap. Replace the entire condensate assembly. NOTE: Before installation, clean out the condensate collector with water to remove any foreign matter that may block the condensate line. Do not install the condensate assembly if a component is lost or missing. Replace the entire assembly.
Figure 16 - Condensate Piping Suggestions NOTES: 1. Condensate line must be pitched at least 1/4" per foot to properly drain. If this cannot be done, or a very long length of condensate hose is used, you must increase the condensate line to a minimum of 1” ID and place a tee in the line after the condensate neutralizer to properly reduce vacuum lock in the drain line. 2. Plastic pipe should be the only material used for the condensate line.
Figure 17 – Piping Exhaust around Obstructions – Suggested Condensate Removal E. EXHAUST VENT AND INTAKE PIPE SIZING 1. The exhaust vent and intake pipes are 3” for EFT-55/80/110/155/199/285 models, and 4” for the EFT-399. 2. The total equivalent length of exhaust vent and intake pipe should not exceed 200 feet for all models EXCEPT the EFT-285. Total equivalent length for the EFT-285 should not exceed 150 feet. a.
o b. For example: If the 3” exhaust vent has two short 90 elbows and 10 feet of PVC pipe we will calculate: Exhaust Vent Equivalent Length = (2x5) + 10 = 20 feet. o o Further, if the 3” intake pipe has two short 90 elbows, one 45 elbow, and 10 feet of PVC pipe, the following calculation applies: Intake Pipe Equivalent Length = (2x5) + 3 + 10 = 23 feet. The Exhaust Vent Equivalent Length + the Intake Pipe Equivalent Length equal the Total Equivalent Length.
G. DIAGRAMS FOR SIDEWALL VENTING Figure 19 – Sidewall Venting with Tee (Intake) and Coupling (Exhaust) (Standard Equipment) and with Optional Kit NOTE: Vent piping should be 12” over anticipated maximum snow level. NOTE: Drawing is meant to demonstrate system venting ONLY.

When placing support brackets on vent piping, the first bracket must be within 1 foot of the boiler and the balance at 4 foot intervals on the vent pipe.
K. VENTING THROUGH AN EXISTING SYSTEM This boiler may be vented through an existing unused vent system. The inner diameter of the existing vent system is utilized for the combustion air source. Two methods have been approved for such venting: Concentric Venting and Venting as a Chase. Do not install the boiler into a common existing vent with any other boiler. This will cause flue gas spillage or boiler malfunction, resulting in substantial property damage, severe personal injury, or death.
VENT / AIR INLET SIZE 3” 4” Table 13 – Minimum Vent / Chase Sizing MINIMUM EXISTING VENT / CHASE SIZE 5” 7” 2. VENTING AS A CHASE When venting as a chase, follow all instructions included in Part 6 – Venting, of this manual, as well as the previous Concentric Venting section. See Figure 25 for chase venting demonstration. Figure 25 – Existing Venting as Chase NOTE: Drawing is meant to demonstrate system venting ONLY.
L. INDOOR COMBUSTION AIR INSTALLATION IN CONFINED OR UNCONFINED SPACE NOTE: This installation is intended for commercial applications. For residential applications, it is recommended to pipe intake combustion air from the outdoors. This boiler requires fresh, uncontaminated air for safe operation and must be installed in a mechanical room where there is adequate combustion and ventilating air. NOTE: To prevent combustion air contamination, see Table 3.
Figure 27 – 1, 27 - 2 NOTE: These drawings are meant to demonstrate system venting only. The installer is responsible for all equipment and detailing required by local codes.
PART 7 – GAS PIPING FAILURE TO FOLLOW ALL PRECAUTIONS IN THIS SECTION COULD RESULT IN FIRE, EXPLOSION, OR DEATH! A. GAS CONNECTION The gas supply shall have a maximum inlet pressure of less than 14" w.c. (3.5 kPa), and a minimum of 3.5" w.c. (.87 kPa). The entire piping system, gas meter and regulator must be sized properly to prevent pressure drop greater than 0.5" (.12 kPa) as stated in the National Fuel Gas Code. This information is listed on the rating label.
4. It is important to support gas piping as the boiler is not designed to structurally support a large amount of weight. 5. Purge all gas lines thoroughly to avoid start up issues with air in the lines. 6. Sealing compound (pipe dope) must be used and approved for gas connections. Apply sparingly, and only to the male threads. Care must be taken when applying compound to prevent blockage or obstruction of gas flow which may affect the operation of the boiler.
DO NOT adjust or attempt to measure gas valve outlet pressure. The gas valve is factory-set for the correct outlet pressure and requires no field adjustment. Attempts by the installer to adjust or measure the gas valve outlet pressure could result in damage to the valve and cause substantial property damage, severe personal injury, or death. D.
PART 8 – FIELD WIRING To avoid electrical shock, turn off all power to the boiler prior to opening an electrical box within the unit. Ensure the power remains off while any wiring connections are being made. Failure to follow these instructions could result in component or product failure, serious injury, or death. Such product failure IS NOT covered by warranty. ELECTRICAL SHOCK HAZARD - Turn off electrical power supply at service entrance panel before making any electrical connections.
3. Connect the boiler pump as shown in Figure 31 to the terminals marked 1 – (HOT), 2 – (NEUT), and 3 – (GND). The connections shown are suitable for a maximum continuous pump draw of 3 amps at 120 volts. If the pump requires more current or voltage than the 120 volts supplied, an external motor starter or contactor will be required. E. ALARM CONNECTIONS The control includes a dry contact alarm output. This is an SPDT circuit, rated at 5 amps at 120 volts.
NOTE: For correct mounting procedures, follow instructions provided with the sensor. NOTE: If sensor wires are located in an area with sources of potential electromagnetic interference (EMI), the sensor wires should be shielded, or the wires routed in a grounded metal conduit. If using shielded cable, the shielding should be connected to the common ground of the boiler. I. INDIRECT SENSOR There is no connection required if an indirect water heater is not used in the installation. 1.
2. Use standard CAT3 or CAT5 computer network patch cables to connect the communication bus between each of the boilers. These cables are readily available at any office supply, computer, electronic, department or discount home supply store in varying lengths. If you possess the skills you can also construct custom length cables. 3. It is recommended to use the shortest length cable that will reach between the boilers and create a neat installation.
4. Connect the boiler pump to the terminals marked 1 (HOT), 2 (NEUT) and 3 (GND). 5. Connect the system pipe sensor to the terminals marked 10 and 11. NOTE: See Figure 32 for Cascade Master and Follower Wiring detail. N. CASCADE FOLLOWER PUMP AND SENSOR WIRING 1. Connect the boiler pump to the terminals labeled 1 (HOT), 2 (NEUT), and 3 (GND). 2. An alarm bell or light can be connected to the alarm contacts of the follower boiler.

PART 9 – START-UP PREPARATION Thoroughly clean and flush any system that has used glycol before installing the boiler. Provide the customer with a material safety data sheet (MSDS) on the fluid used. A. CHECK / CONTROL WATER CHEMISTRY Chemical imbalance of your water can cause severe damage to your boiler and associated equipment, and may also affect efficiency. You may have to have your water quality professionally analyzed to determine whether you need to install a water softener.
Test/replace freeze protection fluid 1. For systems using freeze protection fluids, follow fluid manufacturer’s instructions to verify inhibitor level and that other fluid characteristics are satisfactory. 2. Freeze protection fluid must be replaced periodically due to degradation of inhibitors over time. Follow all fluid manufacturer instructions. NOTE: BOILER FAILURE DUE TO IMPROPER WATER CHEMISTRY IS NOT COVERED BY WARRANTY. B.
5. The system may have residual substances that could affect water chemistry. After the system has been filled and leak tested, verify that water pH and chlorine concentrations are acceptable by sample testing. It is important to purge the system of air to avoid damage to the boiler. E. PURGE AIR FROM WATER SYSTEM IMPORTANT! While commissioning the system, the air vent on top of the boiler must remain fully open to allow the boiler to properly fill.
5. Once the external thermostat circuit wiring is checked and corrected if necessary, reconnect the external thermostat circuit wires to the boiler low voltage terminal strip. Allow the boiler to cycle. G. CONDENSATE REMOVAL 1. The boiler is a high efficiency condensing boiler. Therefore, the boiler has a condensate drain. Condensate fluid is nothing more than water derived from combustion products, similar to that produced by an automobile when it is initially started.
d. Set the Cascade Address parameter 15 to 1 for the first follower, 2 for the second follower, etc., depending on which boiler you are programming. e. Change “CASCADE MODE” parameter to “926 BOILER”. This makes the boiler a follower and enables all data to be transferred between boilers as needed for the system to function to full capability. f. Exit the system menu. NOTE: For the system to operate properly, the temperature set point of the follower must match that of the master boiler. J.

This error only occurs if a technician is programming the control and the programming function fails. The only way to recover from this error is to reprogram the control.
Table 29 PART 14 – MAINTENANCE A. MAINTENANCE PROCEDURES Periodic maintenance should be performed once a year by a qualified service technician to assure that all the equipment is operating safely and efficiently. The owner should make necessary arrangements with a qualified heating contractor for periodic maintenance of the boiler. The installer must also inform the owner that a lack of proper care and maintenance of the boiler may result in a hazardous condition.
The combustion chamber insulation in this product contains ceramic fiber material. Ceramic fibers can be converted to cristobalite in very high temperature applications. The International Agency for Research on Cancer (IARC) has concluded, “Crystalline silica inhaled in the form of quartz or cristobalite from occupational sources is carcinogenic to humans (Group 1).” Avoid breathing dust and contact with skin and eyes. Use NIOSH certified dust respirator (N95).
2. Close isolation valves on the return and supply connections to the boilers as shown in the piping diagrams within this manual. Slowly open the ball valves and release pressure into a bucket. Once pressure is released, connect a hose to the water line to flush the boiler. Scale removing solution may be used, but must be approved for use with stainless steel and FDA approved for use in a potable water system. 3. Thoroughly flush the heat exchanger before commissioning the boiler back in service. D.
Do not install the condensate assembly if a component is lost or missing. Replace the entire assembly. Failure to follow this warning could result in property damage, serious personal injury, or death. 6. Fill the condensate trap with fresh water prior to reassembly on the boiler. 7. Slide the condensate trap adapter onto the drain tube until the holes line up with the groove. 8. Insert stainless steel hitch pin to lock condensate adapter to the drain tube. 9.
