THIS HEATER IS DESIGNED TO BURN THE FOLLOWING APPROVED FUELS:
Used 5W through 50W Crankcase Oils
Used Automatic Transmission Fluid
No. 1 and No. 2 Fuel Oils
• The Lanair Heater provides the owner with a dependable, versatile and simple means of
burning No. 1 and No. 2 fuel oils, 5W through 50W used crankcase oils, and used automatic transmission fluids. Maintained correctly, the heater will give you years of service.
Please carefully read this owner’s manual. If in any case you have a problem with your
heater,or its installation, you should contact the Lanair Customer Service Department at
1-800-753-1601.
• Do not attempt to start the burner when excess oil, oil vapor, or fumes have accumulated! Never press the red button on the oil primary control more than twice! This could
cause excess vapor, or fuel to ignite causing damage to the heater and/or chimney.
• Do not store or use gasoline, or any other flammable liquid and/or vapors near this
heater.
• This heater is not designed for use in hazardous atmospheres such as: Paint Shops, Feed
Mills, installations where explosive or flammable conditions are present or could occur.
WARNING! Lanair heaters rely on natural draft. Down drafts (positive pressures)
in the heaters chimney will occur in buildings where negative pressures are created
by exhaust fans, (car exhaust, paint booths, etc). Do not try to use a power vent to
!
overcome a down draft (positive pressure). An adequate make-up air system is
required when exhaust fans are used (consult your heating contractor).

Section 2 - Heater Installation
General Requirements
1. Do not install the heater on a combustible surface of any kind. For minimum clearance to
combustible material (see Page 9)
2. Install the heater in a location to utilize total heat throw.
3. Install the heater in a location to permit a correct outdoor chimney exit to eliminate
down drafts, and provide easy chimney installation and maintenance. Class A chimney
MUST be used when passing through any wall or ceiling. See Section 3 Chimney
Installation
4. Install the heater in a location to permit the fuel supply to be as close as possible.
5. Do not install the heater more than 10 feet above the top of the fuel supply tank.
6. Before suspending the heater check the supporting structure and reinforce if necessary
to support the weight of the heater/system.
7. Use 3/8” steel threaded rod to suspend the heater from a capable load carrying ceiling
structure when not using the Lanair Waste Oil Storage Tank.
8. The heater must be suspended level for proper operation. A heater that is not level could
cause a hazardous situation in which personal injury or property damage may result.
CAUTION: DUCT WORK RUNS MUST BE DESIGNED AND INSTALLED BY A
LISCENSED HEATING CONTRACTOR

Section 3 - Chimney/Vent System
Figure 2 - Typical Chimney Installation
NOTE: Class "A" components require a 2" clearance from combustible
materials. All other
chimney components
require a minimum 18"
clearance from combustible materials
General Requirements
1. Safe operation of any gravity vented heating appliance requires a proper air make-up
system to prevent the heater exhaust gases from being drawn into the building.These
gases could cause death, serious injury, and/or property damage.Exhaust fans, paint
booths may cause draft problems.
2. Never vent this heater into another heating appliances chimney. Never vent into ‘Class B”
chimney.Gas heaters use “Class B” chimney, it is rated for a much lower temperature than
is required for your waste oil furnace.This heater must have its own separate “Class A”
chimney.
3. Inspect and maintain the chimney on an annual basis.
FAILURE TO PROVIDE PROPER VENTING OF THE HEATER EXHAUST
GASES COULD RESULT IN DEATH, SERIOUS INJURY, AND/OR PROPERTY
!
DAMAGE. FOLLOW CHIMNEY MANUFACTURERS INSTRUCTIONS.

Barometric Damper Position
ORIZONTAL
H
General Requirements (cont.)
4. Install a U.L. listed barometric damper in the chim-
ney. Do not reduce or enlarge the vent pipe.
5. Each 90° elbow equals a 10’ run of chimney.The
maximum run for the chimney connector is 30’ (See
illustrations on pp. 12 & 14).
6. To prevent the drawing of exhaust gases into the
building, keep the barometric draft control at least
24” from the heater,exhaust fan etc..
7. Position the draft control as shown. Barometric
Damper gate pins must be horizontal (Level or
parallel to the floor) for proper operation.
8. Secure all connections in the chimney connector with 3 screws per joint.
9. The chimney connector clearance to any combustible material is 18”. The “Class A”
chimney clearance to any combustible is 2”. Follow the chimney manufacturer’s instructions.
10. Do not install heat re-claimers, manual draft controls, or any other type of restrictive
control in the chimney.
11. Install clean out tee with a cap, at the transition of the chimney. FOLLOW CHIMNEY
MANUFACTURERS INSTRUCTIONS.
NOTE: Barometric Damper may
be mounted horizontally or
vertically. Angle gate pins
must be horizontal (level or
parallel to floor) for proper
operation.
VERTICAL
12. Use “Class A” insulated chimney pipe to vent exhaust gases through wall, ceilings, attics,
roofs, combustibles, etc. Class A chimney must be used for the entire run once passing
through a wall of ceiling.
13. Vent chimney at least 3 feet above the roof and at least 3 feet higher than any portion
of the building, roof, or obstruction within 10 feet of the chimney.
14. The chimney cap should be at least 3’ above the chimney exit through the roof.
15. Do not use a rotating chimney cap. Use a non-restrictive “Class A”cap made for the type
“Class A”chimney you are using. Follow chimney manufacturer’s instruction.
16. The chimney must be capable of producing a negative -.02 W.C. draft when cold and -
.06 W.C. draft when hot. Refer to Section 5 Draft Instructions.Refer to Section 3.10 for
typical Chimney Installation.
Visit our website at: www.lanair.com

Section 3 - Chimney/Vent System
17. If you are unable to attain the proper draft,check for exhaust fans in the building.To test
if there is a problem, open an overhead door and see if you now have the proper draft.
You may have to add one or more sections of “Class A” chimney to the roof to get the
proper draft.
18. The heater and chimney must be installed in accordance with all state and local
codes.The heater must be installed in accordance with the specifications listed in
this manual.The chimney must be installed per the chimney manufacturer’s
instruction. Use “Class A”chimney only.
QUESTIONS?... Contact Customer Service at 1-800-753-1601 M-F 8:00 am- 4:15 pm CST

Section 4 - Draft
The Lanair heater should have a (negative) -.02 draft reading when cold, and a (negative) -.06
when hot. Check the heater when it is running after 45 minutes. If the reading is not what it
should be, adjust the barometric damper according to the instructions provided with the
damper.The draft reading should be taken with a manometer. Consult your heating contractor, or a manometer can be purchased from the Lanair Customer Service Department .

Section 5 - Fuel Supply Tank Installation
If using a Lanair supply tank follow instructions included with the tank.
!
General Requirements
1. The fuel supply tank and supply lines must be installed in accordance with the National
Fire Protection Association requirements, as well as State and Local ordinances.
2. Regulations require oil storage tanks located inside not too exceed 275 gallons individu-
ally, and are not to exceed a total capacity of 550 gallons in one building. Check State
and Local codes.
3. Locate the fuel supply tank inside the building as close to the heater as possible. It
should be no further than 25 feet from the heater to avoid oil flow problems.
4. The fuel supply tank must be mounted below the level of the burner and the by-pass
regulator.Mounting the fuel supply tank above the burner will create head pressure and
over-fire the burner voiding the warranty.
5. Pitch the fuel supply 2º with the drain valve at the lowest end to drain off water and
sludge. Sludge may have to manually be removed.
6. Some ordinances may require the fuel supply tank to be vented to outside, and above
the roofline. Check State and Local codes. Keep the vent clear.
7. Install the fuel tank fill pipe at the end of the tank and above the drain.
8. Label the fuel tank for the recommended fuels.
9. Strain all fuel with a 50 X 50 mesh strainer before putting fuel into the tank.
10. When filling the fuel tank with a motorized pump, never leave unattended to prevent
over filling and/or spillage.
11. Keep cap on the fuel tank when not filling.
For optimum performance, the waste oil pump manufacturer recommends that multi-weight oils such as 5W-30W be maintained at 32˚ F
!
minimum and straight weight oils such as 40W and 50W be maintained
at 50˚ F minimum.
