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.
Adjustable Locking Louvers
The MX Series heaters feature spring
loaded locking louvers.To adjust:
s Slowly push the louver to the left
until the locking pin disengages.
NOTE: Do not allow the pivot pin
to come out of the hole.
s Tilt the louver forward/backward
until desired position is obtained.
s Release louver so locking seats

Figure 2 - Typical Chimney Installation
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

Section 3 - Chimney/Vent System
General Requirements (cont.)
4. Install a U.L. listed barometric damper in the chim-
ney. Do not reduce or enlarge the vent pipe.
5. Do not use more than one 90° elbow. Each 90°
elbow equals a 10’ run of chimney.The maximum
run for the chimney connector is 30’.
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 (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
instructions.
Barometric Damper Position

NOTE: Barometric Damper may
be mounted horizontally or

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.
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 manufactu
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 4 Draft Instructions. Refer to Section 3.10 for
typical Chimney Installation.
NOTE: Do not install chimney in front of the heater (in air stream of fan)
rer’s instruction.

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

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 .
