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
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 furnace 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 furnace 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 furnace 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 and face 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 furnace, as they may be ignited by the burner. Do not operate the furnace 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 furnace. 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 furnaces are
installed 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 furnaces 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.
2.1 Technical Guidelines
1. All components of your furnace are factory-tested to ensure proper operation. Do not
tamper with controls.
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 threaded connections only.
5. Do not use Teflon tape on any 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 furnace 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 (no loops)
to avoid air pockets.
10. Remember to remove the blower shipping strap prior to installation.
11. Maximize vertical run of flue, and minimize horizontal run. Allow access for clean-out.
12. Mount the wall thermostat to an interior wall. Do not allow it to hang by the wiring
harness. Do not mount it to the furnace cabinet.
13. 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 EnergyLogic low-
level cut off switch is recommended to prevent low fuel operation.
14. Never use compression fittings for tubing connections, as they will leak and cause the
burner to shut down.
15. Care should be taken not to over-tighten or cross thread brass fittings.
16. Applying a thin film of anti-seize compound to cabinet side of burner gasket may
reduce gasket sticking to cabinet when swinging burner open.
17. Another source of heat is recommended for periods when the furnace may be off-line
for maintenance or for any other reason.

2.3 Furnace Placement Guide
It is important to plan the furnace 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 furnace? Check your local building codes. The EnergyLogic furnace
requires 115 VAC/60 Hz power, supplied through a dedicated, hard wired, circuit breaker – 25
Amp 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 or flammable materials present at interior or exterior locations? Check your roof
warranty about penetration for 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°C) 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.
8
Call 1-615-471-5290 for Technical Support

Minimum Clearance – Safe clearances to combustibles (Section 1.6) shall be
adhered to.
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 furnace. 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 drip cap and
baffle, burner access, etc.). If desired, the furnace can be wall mounted or hung from the
ceiling at some distance from the oil tank.
Cabinet Orientation vs. Air Flow Direction – Consider the workspace to be heated.
Consider proximity to windows, doors, etc. The EnergyLogic used oil furnace is designed such
that the louver and cabinet panels may be swapped and the cabinet can be rotated 180º.
Consider whether or not this would be advantageous for your application. Contact
EnergyLogic if louvers are needed on both sides.
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

the fuel tank. If you are mounting the furnace to a structural ceiling or wall proceed to Section
3.4. Do not mount an EL-350H furnace to any EnergyLogic Tank smaller than 250
gallons.
3.3.1 Locate the EnergyLogic Used Oil Storage Tank
EnergyLogic supplied workbench tanks are U.L. listed and pressure tested at the factory.
However, new tanks must be leak tested by qualified installers prior to installation and use
(refer to local codes and regulations). The tank must be located inside. If you are mounting the
furnace to the tank, make sure that the tank is located beneath the desired location of the
furnace. The tank must be on level flooring that will adequately support the full weight when
loaded. Use a pallet jack or fork lift (on the bottom side of tank) to move the empty tank. Do not
push or drag the tank. Maintain clearance from the tank to any source of heat
(refer to local codes and regulations).
The furnace cabinet is heavy and will need to be lifted to a height of 8 feet
above the floor. Use appropriate lifting and safety equipment.
3.3.2 Tank Stands and Cabinet Installation (250 gallon tank shown)
1. Locate the two large “L-shaped” Support Stands, and slide the long end of each into
the square tubes on the rear of the tank. Slide the stands all the way to the bottom and
do not install any bolts at this time.
2. Inspect the furnace cabinet to make sure that the louvers for the heat output, the
burner end, and the flue end are oriented as desired. If not, switch the louver panel on
the front of the furnace with the blank panel that is on the rear of the furnace prior to
installing the cabinet.

3. HEAVY! Using a forklift
or other lifting device, lift the cabinet
onto the stands. Position the lift forks
close to the lower mounting bolts on the
bottom panel, but leave enough room
for tank stands. Continue to support the
cabinet with the lifting device until all
cabinet and support stand hardware
have been properly secured.
4. Remove the four (4) 3/8 inch x 3 inch
bolts and washers from the bottom of
the cabinet.
5. Align the holes in the stands with the
holes in the cabinet and secure the
cabinet to the stands using the same four (4) 3/8 inch x 3 inch bolts and flat washers.
6. Install the (2) plastic stand end caps by pressing them into the open tube ends.
7. HEAVY! Using the forklift or
other lifting device, raise the cabinet and
stands until the bolt holes are visible in the
square tubing on the rear of the tank.(EL-140H
and EL-200H only) Insert (4) 3/8 inch x 4 inch
bolts with flat washers through the box tubing
and stands (2 sets per side). Install flat
washers, lock-washers, and then nuts onto the
bolts and tighten (refer to figure).
8. (EL-350H only) Insert (2) of the 3/8 inch x 4
inch bolts with flat washers through the lower
holes only on the box tubing and stands (1 set
per side). Install flat washers, lock-washers,
and then nuts onto the bolts and tighten.
9. (EL-350H only) The 350 furnaces require two
additional angle braces for support. These
are shown in figure. Secure the braces using
the remaining (4) 3/8” X 4” bolts, washers
and nuts.
10. You have completed the Tank Bracket and
Cabinet Assembly for a Tank Mount System.
Proceed to Section 4 to install the furnace
components.

3.4 Furnace Cabinet Installation – Not Mounted on a Tank
3.4.1 Ceiling Mount with Threaded Rod
HEAVY! Use proper lift equipment. Combustible materials must
not be near the furnace. See required clearances in Section 1.6.
Ceiling Mount Steps (Refer to figure):
1. Determine the desired location of furnace. Determine the length of the 3/8” threaded rod
(3/8 – 16) that will be used to hang the furnace. Measure the hole pattern on the top of
the furnace (where existing 3/8” bolts are). This is your reference for rod spacing.
2. Hang 3/8” threaded rod (4 pieces) from a secure structure such as unistrut. Use flat
washers, lock washers and nuts to secure the rods to the structural member. Leave the
connection just hand-tight until the rod has been threaded into the furnace on the other
end. Next, you will work on the other end of the rods (furnace end).
3. Turn nuts onto the this end of each threaded rod, keep turning until the nuts are several
inches up the rod.
4. Using proper lift equipment, carefully lift the furnace cabinet to the desired location.
Remove the existing 3/8” bolts from the top of the cabinet. Place a lock washer and flat
washer on each rod, while you screw the threaded rod 1” (2.54 cm) into the threaded
holes in the top of the cabinet. After threading the rods 1” into the top of the cabinet,
tighten the nuts. Measure and note the level in both directions, and continue to the next
step.

steel across structural
ceiling joists or beams.
Make sure that the
resulting structure will
