Do not start the burner unless all cleanout panels are secure in place.

KEEP THE FUEL VALVE NEAREST THE SUPPLY TANK SHUT OFF WHEN THE BURNER IS SHUT OFF FOR EXTENDED PERIODS.

Turn off power to the burner when the burner is off for extended periods.

The boiler is designed to be installed in a manner that restricts its access.

USED OILS CONTAIN HEAVY METALLIC COMPOUNDS AND FOREIGN MATERIALS. WHEN BURNED, THESE COMPOUNDS ARE EMITTED FROM OR DEPOSITED WITHIN THIS HEATING APPLIANCE AND THEREFORE CARE SHOULD BE TAKEN WHEN USING, CLEANING AND MAINTAINING THIS EQUIPMENT.

EnergyLogic recommends that the building, domestic hot water system or process have a secondary heat source during times the boiler is down for maintenance or service. Used oil boilers require maintenance. Also, used oil may sometimes be unavailable or burn poorly due to contaminants (such as water) in the oil.

1.3 Safety Hazards

There are potential hazards associated with operation of this or any other boiler. In addition to the codes and regulations listed in the following section, general safety rules and precautions should be followed at all times to prevent accidents that could lead to personal injury, death or property damage. Only those qualified should perform the tasks. Specific safety hazards include:

Electricity: The EnergyLogic boiler operates on 115V/60Hz electrical power. Turn power off at the circuit breaker and lock it out prior to performing any work on the boiler system or any of the components. Make sure covers are in place during normal use. Use only copper conductors.

Liquid Fuels: Used oils must be handled properly to prevent spills. Uncontained oil leaks may contaminate the local water supply. Ensure that all national and local codes are

Call 1-615-471-5290 for Technical Support

followed in regards to the requirements for spill containment and SPCC paperwork. Oil leaks pose slip/fall hazards, and pose a risk for fires. DO NOT USE GASOLINE OR ANY OIL CONTAINING GASOLINE. Do not add any cleaning fluids or oil additives to the used oil burned in this appliance. The use of unauthorized fuels will void the warranty and U.L. listing. See section 1.5.1 for a list of allowable fuels. The end user of the boiler is responsible for ensuring that all correct precautions are taken in managing their used oil.

Combustion Exhaust Gases: The exhaust products from the combustion are dangerous to breathe. The boiler must be attached to a flue which properly vents the exhaust out of the building to the atmosphere at all times, to assure safe and proper operation of the burner. If proper draft cannot be established, changes to the building construction or a draft inducer will be required in order to provide adequate make-up air.

Safe Maintenance: Used oil contains mineral additives and deposits called “ash” that will not burn. Ash collects in the boiler and flue with regular use over time. Ash must be cleaned out of the combustion chamber/heat exchanger and flue pipe on a scheduled basis. Follow the minimum maintenance instructed in section 8. Wear proper protective clothing; including gloves, safety glasses, and a dust mask or respirator whenever any cleaning is performed, including the cleaning of the heat exchanger, flue piping and exhaust stack.

Vapor/Dust Ignition: Do not store or use gasoline or other flammable liquids or vapors near this boiler, as they may be ignited by the burner. Do not operate the boiler in dusty or otherwise dangerous environments.

Flammable liquids: Do not create a fire or explosion hazard by using or placing flammable liquids such as gasoline or solvents near the boiler. A flammable liquid is any liquid that has a closed-cup flash point below 100°F (37.8°C), as determined by the test procedures and apparatus set forth in 1.7.4 of NFPA 30.

Minimum Clearance – Safe clearance to combustibles (Section 1.6) shall be adhered to.

Height, Weight, Guarding and General Safe Practices: The boilers are installed with flue systems at heights which pose a risk for injuries due to a fall. Many of the components are heavy, and pose the risk of injury with improper lifting and handling. Always follow safe practices and use proper equipment. Never climb on the equipment. Do not take risks when installing or servicing the equipment. All cover plates, enclosures, and guards must be maintained in place at all times, except during maintenance and servicing. Failure to observe general safety rules and to follow safety rules specific to the tools and equipment used or being worked on may result in product/property damage, personal injury or death.

2. Installation Considerations

EnergyLogic boilers are designed to operate reliably over a wide range of conditions. However, it is important to read this section before installation to prevent unnecessary work or problems.

2.1Technical Guidelines

1.Most components of your boiler are factory-tested to ensure proper operation. Do not tamper with factory settings or fittings. The settings on the triple aquastat may be adjusted.

2.Pre-assembled fittings are sealed with thread-locker sealant and do not require additional tightening.

3.Always supply power through a dedicated, hard-wired (copper only), 115VAC/60Hz circuit with a 25 Amp maximum breaker. Check local codes.

4.Do not use the provided thread-locker sealant on flare fittings. Use the provided sealant on all NPT fuel line connections only.

5.Do not use Teflon tape on any fuel connections. Loose strands may block small orifices, affecting unit operation or may damage components.

6.Route all fuel lines inside building to prevent exposure to cold weather. If this is not practical, call EnergyLogic for application support.

7.Locate boiler and tank in a dry area above 50°F (10°C) at all times.

8.If not installing the pump to an EnergyLogic Tank, mount it according to guidelines in the EnergyLogic Top Suction Kit packaging instructions.

9.Do not kink copper tubing. Route tubing as straight and vertical as possible to avoid air pockets.

10.Maximize vertical run of flue, and minimize horizontal run. Allow access for clean-out.

11.Do not allow your tank to run out of fuel. If the tank runs out of fuel, air and contamination will be introduced into the fuel delivery system. An optional EnergyLogic low-level cut off switch is recommended to prevent low fuel operation.

12.Never use compression fittings for fuel tubing connections, as they will leak and cause the burner to shut down.

13.Care should be taken not to over tighten or cross thread brass fittings.

14.Applying a thin film of anti-seize compound to burner gasket may reduce gasket sticking to vessel when servicing.

15.Another source of heat is recommended for periods when the boiler may be off-line for maintenance or for any other reason.

2.2 Tools Required

Below is a recommended list of tools and equipment that may be used to aid in the installation of the EnergyLogic boiler. This is a minimum list for a simple system, excluding the hydronics and plumbing.

5/16” Combination Wrench	Pipe Wrench Set
3/8” Combination Wrench	Flat Blade Screwdriver
7/16” Combination Wrench (x2)	1/4” Hex Wrench or Driver
1/2” Combination Wrench	Wire Cutter (to remove tie straps)
5/8” Combination Wrench	Lift Device
11/16” Combination Wrench	Safety Ladder or Lift
3/4” Combination Wrench	(Tools Required for Flue Kit Installation)

2.3 Boiler Placement Guide

It is important to plan the boiler and tank placement, wiring, piping and flue prior to installation.

Electrical Wiring - Will the layout of your building allow safe routing and installation of electrical wiring to the boiler? Check your local building codes. The EnergyLogic boiler requires 115VAC/60Hz power, supplied through a dedicated, hard wired, circuit breaker - 25Amp maximum. Use copper conductors only. Electricity is very dangerous. Wiring must be installed by a qualified electrician. In the U.S., consult the National Electric Code (NEC) and local building codes for additional requirements. In Canada, consult the Canadian Electrical Code, Part I.

Flue Pipe - Is ceiling/roof or wall location suitable for a flue pipe to pass through? Are any obstacles present at interior or exterior locations? Check your roof warranty about penetration of the flue pipe. Check your local building and fire codes.

Combustion and Make Up Air Requirements – It is necessary to ensure that adequate air for safe combustion is provided for oil-burning appliances and equipment. Refer to NFPA 31, Chapter 5 for requirements based on the total input BTU rating of all appliances in the space. In Canada, reference CSA Standard B139/CGA B149.

Tanks - The oil tank is to be vented to the outside of the building. Oil temperature should be maintained at 50°F (10°) and above. Tank shall be at least 5 feet away from any source of heat and should not obstruct service meters, electrical panels, or shut off valves. Check building, environmental and fire codes for containment and other restrictions.

Minimum Clearance – Safe clearances to combustibles (Section 1.6) shall be adhered to. A non-combustible flooring structure is required for the boiler.

8

Call 1-615-471-5290 for Technical Support

Distance from Flammable Liquids – Do not create a fire or explosion hazard by using or placing flammable liquids such as gasoline or solvents near the boiler. A flammable liquid is any liquid that has a closed-cup flash point below 100°F (37.8°C), as determined by the test procedures and apparatus set forth in 1.7.4 of NFPA 30.

Access - Position the used oil storage tank to provide adequate access to filling ports, filter, drain valve and pump. Leave an unobstructed path for shop vehicles and equipment. Consider access needed for service (heat exchanger cleaning, flue cleaning, removal of breech panels, burner access, etc.). Installation of system piping should not hinder required access for service.

Vessel Placement in Motor Fuel Dispensing Facilities and Repair Garages – Heat producing appliances shall not be allowed unless installed with provisions outlined in NFPA 30A, section 7.6.

Structural requirements (Canada) – In Canada, the structure in which the used oil burning appliance is housed shall be no less than 4.6m (15ft) high at the point where the appliance is situated and have a minimum length and width of 6m (20ft) and a minimum floor area of 37m2 (400ft2). In addition, the installation including flue stack height requirements and distance from property line shall be in accordance with the authorities having jurisdiction concerning environmental quality as well as fuel, fire, and electrical safety and Table 7 in CSA B140.0-03 (clause 22.3.2).

Other Considerations for EnergyLogic Boilers:

They are constructed with ASME certified pressure vessels (30 psi maximum pressure).

The ASME stamp is located on boiler plate on the vessel under a removable panel. They have Canadian Registration. The CRN number is located on the boiler plate. They are UL Listed in the US and Canada. The UL mark and specification label are on a boiler panel.

They are fire-tube boilers. This means that hot combustion gases flow through tubes, transferring heat to water that surrounds the tubes.

They are carbon steel boilers. With a ¼” steel shell, they are of a durable construction, and much lighter than cast iron models. Since they are carbon steel however, there are some restrictions on the return water temperature to prevent corrosion (minimum return temperature of 140°F).

They are wet-based boilers. This means that the combustion chamber and tubes are surrounded by water that keeps the steel cool and prevents chamber deterioration. They are non-condensing boilers. This means that the flue gases are not allowed to cool enough to create condensation. Due to sulfur in the oil, condensation would create sulfuric acid which would quickly corrode the boiler tubes and chamber.

3.6 Metering Pump Installation – Non-EL Tank (skip if you have EL tank)

If you are metering fuel directly from a tank not supplied by EnergyLogic, the top suction method may be used. Verify regulations prior to installation. Contact your authorized EnergyLogic dealer to purchase an EnergyLogic Top Suction Kit if one was not included in your original purchase. The use of a genuine EnergyLogic Top Suction Kit (figure) will help to avoid common fuel delivery issues with this type of

installation.

Installation of the Top Suction System:

1.Install the vacuum and pressure gauges on the pump. Follow steps 1 & 2 in previous section.

2.If you purchased an EnergyLogic Top Suction Kit, follow the instructions included in the packaging. Refer to the following for general guidelines.

AirScape Accessory

(Optional)

EL Top Suction Kit Installed

Guidelines for Top Suction Method:

Purchase an EL Top Suction Kit (if your package did not include one).

Keep in mind that the main storage tank will need to have enough capacity to allow for separation of water from the used oil. Never meter oil directly from oil drums or totes.

EnergyLogic’s fuel pump is designed for interior use only (must be mounted inside a protective structure). The minimum recommended fuel temperature is 50oF.

The pump may be mounted to a nearby wall, within 6’ of the tank. The ideal placement of pump is with the inlet above the filter head assembly, which should be mounted above the tank fitting. Maximum vertical lift for the suction line should not exceed 6 feet (2m). This includes the portion of line inside of the tank.

The EL Filter Head Assembly is to be placed such that it filters the oil prior to pump. A shut off valve should be placed prior to the filter head in order to do a vacuum check.

The pump assembly and wiring connections must be at least 18 inches (46 cm) above the floor to meet National Fire Protection Association (NFPA) codes for repair garages.

The inlet to the suction line should be at least 8 inches (20 cm) off the bottom of the tank, to prevent water and sludge from entering the system.

Use minimum 3/8” OD x 1/32” wall thickness copper tubing. Never create loops.

Use 45 degree flares on the copper tubing. Loose fittings or cracked flares cause problems. Suction leaks cause air to get sucked into the fuel system. All suction leaks must be eliminated.

Used-oil contains water from condensation. A drain valve on the bottom of the tank should be used regularly to remove water and sludge that separates out of the oil and settles to the bottom of the tank. If your tank does not have a drain valve, you must have the tank pumped out completely (periodically) to remove the water and sludge.

4.2.2 Triple Aquastat Temperature Controller Installation.

1.Remove the cover from the triple aquastat control.

2.Fill the triple aquastat thermal well (refer to figures) with thermal conductive grease (provided), as follows: Fold the plastic bag of compound lengthwise and twist it gently. Then snip off end of bag and work the open end of the bag all the way into the well. Slowly pull out the bag while squeezing it firmly to distribute compound evenly in the well. Wipe excess compound from the outer end of the well.

Fill Triple Aquastat Well with Thermal Conductive Grease before inserting probe.

3.Loosen but do not remove the clamp screw on the case. Insert the aquastat probe into the thermal well until it bottoms out.

19

Call 1-615-471-5290 for Technical Support

4.Fit the case onto the well so that the clamp on the case slides over the well. Securely tighten the clamp screw. Note: Align the controller prior to tightening securely.

5.Set the control settings to the desired temperatures. Set HI to the temperature that you want the water to reach during a call for heat. Set Lo to the temperature that you want the water to maintain in the vessel when there is not a call for heat. Set DIFF to an amount that you want the Lo setting temperature to cycle between. Note: The Hi limit must be set at least 20°F above the Lo limit setting. Do not set the low limit below 140°F.

Remove jumper wire and install room thermostat here, if used.

Lo

DIFF

HI

6.If a room thermostat (or other device) is to be used to call for heat, the factory-installed jumper wire will need to be removed from the triple aquastat and replaced with wiring (24VDC) from the thermostat (refer to figure above) If the jumper is not removed, the control will always sense a call for heat. If this is the case, the burner will always cycle between the high temperature limit and its fixed differential of 10°F, and the water circulation pump will be powered (if this control is used for the circulation pump).

7.If using the circulation pump control on the aquastat, wire the pump control across terminals C1 and C2 using a 115V coil relay to provide separate power to the pump. The amperage rating of the controller is limited to a total load of 8 amps, which is mostly consumed by the burner itself. The relay is necessary to make sure that the controller is not overloaded by the addition of the pump. Make sure to connect according to NEC code, with approved metal conduit. Note: Many installations use separate controls for the pump. Regardless of the pump control method used, be aware of the requirement for a minimum of 140°F return water temperature. If this requirement is not met, the vessel warranty is void.

8.Install the cover to the control.

4.2.3 High-Limit Temperature Controller Installation.

1.Remove the cover from the high-limit temperature aquastat control.

2.Fill the high-limit temperature aquastat thermal well (locate well according to figures) with thermal conductive grease following the same procedure as in section 4.2.2.

4.6 Burner/Vessel Assembly

Now, the burner can be installed on the boiler vessel. This is done as follows:

The burner assembly is heavy. Handle with care.

1.Remove the four (4) nuts from the studs on the boiler door

2.Install the burner gasket onto the studs. NOTE: Gasket sealer should not be used on this gasket. Apply a thin film of anti-seize compound to the vessel side of the burner gasket to help reduce gasket sticking when servicing.

3.Inspect the retention head and electrodes for proper settings (refer to Section 8.5.6).

4.Mount the burner assembly onto the vessel by inserting the burner over the studs.

5.Reinstall and tighten the four (4) nuts.

6.Plug the burner harness into the vessel wiring box (refer to figure). The plug fits only one way. This completes this step for the EL-200B. If you are installing an EL-375B or EL-500B, continue to step 7 to connect the preheater to the burner.

Always unplug the burner before doing any service work on it. Attempting to swing the vessel door open while the burner is plugged in may damage the plug or cable.
