Section 1 - General Specications & Safety
!
•
The Lanair Heater provides the owner with a dependable, versatile, and simple means of
burning No. 2 fuel oil, used crankcase oils (5W through 50W), and used ATF. Maintained
correctly, the heater will give you years of service. Please carefully read this owner’s man-
ual. If in any case you have a problem with your heater, or its installation, you should con-
tact the Lanair Customer Service Department at 1-888-370-6531.
•
Only select models are designed for attachment or use with ductwork. Please con-
rm that you have puchased the correct model for your application.
•
Do not attempt to start the burner when excess oil, oil vapor, or fumes have accu-
mulated! 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 ammable liquid and/or vapors near this heater.
•
Fuel storage must be located a minimum of 5 feet from the heater.
•
This heater is not designed for use in hazardous atmospheres such as: Paint Shops, Feed-
Mills and installations where explosive or ammable conditions are present or could
occur.

WARNING!
Lanair heaters rely on natural draft. Downdrafts (
reverse flow
)
in the
heater’s chimney will occur in buildings where negative pressures are created
by
exhaust fans, (car exhaust, paint booths, etc.). A power vent may not be sucient to
overcome a downdraft. An adequate make-up air system isrequired when exhaust
fans are used (consult your heating contractor).

Section 2 - Systems & Controls
Room Thermostat:
The room thermostat automatically controls the on/o operation of the heater according
to the setting of the desired room temperature. The thermostat works in conjunction with
the oil primary safety control.
Oil Primary Safety Control/Flame Sensor:
The oil primary control is mounted on top of the burner’s electrical box. When the thermo-
stat calls for heat the oil primary control starts the burner by switching on the air solenoid
valve, ignition transformer, combustion air blower, and the fuel pump.The oil primary control
works
with
the
ame
sensor (sometimes
referred
to
as a
cad
cell). The
ame sensor is
mounted inside the burner cover, and faces the ame. The ame sensor monitors
the light
level inside the combustion chamber to ensure a ame is present. If there is a loss
of ame
the primary control will go into its recycle mode. After a period of time, the primary control
will attempt to restart the burner. When this happens, if a ame is established, the
burner
will
continue
to
function.
If
on
start-up
no
ame
is
established
in
30
seconds
the primary
control will lock out, requiring the reset button to be pressed manually.
CAUTION:
Do
not
press
the
reset
button
more
than
twice.
If
the
burner
fails
to
function
properly, refer to
Section 13 - Trouble Shooting.
Fan/Limit Control
The
fan/limit
control
monitors
the
temperature
of
the
air
inside
the
cabinet. When
the
air
reaches a set point (usually 120º F) it will switch on the heater fan. When the temperature in
the cabinet drops below set point usually 90º F the fan/limit control will turn the fan o. If
the temperature exceeds a xed set point, (usually 200º F), it switches the burner (Oil Primary
Control) o until the temperature drops to a safe level. The burner will then restart.
CAUTION:
If the heater shuts down due to “High Limit” temperature conditions, the cause
must be determined and corrected before further use (over ring the unit is normally what
causes this condition).
The fan/limit control also features an external switch to turn the axial fan on manually, by-
passing its automatic function. The Fan/Limit Control is located on the top of the cabinet,
towards the front of the unit.
Barometric Draft Control
The Barometric Draft Control automatically maintains a pre-set chimney draft. It is located in
the chimney connector or ue.
Air Filter/Regulator
The Air Filter/Regulator performs two functions: It removes condensation and dirt from the
air
while
controlling
the amount
of
air
pressure
reaching
the
nozzle
and
air
operated
fuel
valve. The Air/Filter Regulator is mounted on the cabinet near the burner.

Section 2 - Systems & Controls
Electric Air-Solenoid Valve
The electric air-solenoid valve is controlled by the oil primary control. It acts as a shut-o
valve, (it’s open during operation, and closed when the burner is o
). The electric air
-solenoid valve is located inside the burner’s electrical box.
Air Operated Fuel Valve
The air-operated fuel valve controls fuel ow out of the nozzle. When the electric air-
solenoid valve opens and air pressure pushes on the fuel valve diaphragm, the plunger
moves o the nozzle seat allowing fuel to enter the nozzle. The air-operated fuel valve is
located on the back of the air preheater.
Air/Oil Preheater
The air/oil preheater is an assembly that preheats the atomizing air and fuel to a prede-
termined temperature to properly combust used oil. The air/oil preheater is located in the
burner.
Snap Disc
The snap disc accurately controls the temperature of the air/oil pre-heater assembly with
two resistance type cartridge-heating elements. The snap disc is mounted on the oil pre-
heater inside the burner.
Nozzle
The nozzle uses air pressure to help deliver fuel through its small orice, and to atomize the
fuel for proper combustion. The nozzle is located on the end of the air pre-heater opposite
the fuel valve. Replace the nozzle annually, as they are prone to wear by contaminants in
waste oil.
Fuel Bypass Regulator (This is not used with the Optional metering pump)
The fuel bypass regulator controls the pressure of the fuel to the nozzle. The fuel bypass
regulator is located in the line between the outlet side of the pump and the burner.
Fuel Supply Pump
The fuel-supply pump delivers fuel from your oil storage tank to the burner. The fuel supply
pump should be located as close to the fuel supply tank as possible. The fuel supply pump
must be mounted with the motor shaft oriented horizontally.
Optional Metering Pump Assembly
The metering pump delivers fuel from your oil storage tank to the burner. It also controls
the volume of fuel, and no regulator is required. The metering pump should be mounted
with the motor shaft oriented horizontally.

General Requirements
1.
Do not install the heater on a combustible surface of any kind. For minimum clearance to
combustible material (see Page 1).
2.
Install the heater in a location to utilize total heat throw (blown hot air).
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 4 Chimney Installation.
4.
Install the heater in a location to permit the fuel supply to be as close as possible.
5.
If the heater is not installed on a tank stand supplied by Lanair, a metering pump may be
desired in order to eliminate the need to adjust oil ow from a distance.
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”, 16 TPI, steel threaded rod and locking nuts to suspend the heater from a capable
load carrying ceiling structure when not mounting to a 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 XT Series heaters feature spring
loaded locking louvers. To adjust:
•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.
•Tilt the louver forward/backward
until desired position is obtained.
•Release louver so locking pin
seats into the hole.
