Section 2 – Systems & Controls
Room Thermostat:
The room thermostat automatically controls the on/off 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 thermostat 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 in conjunction with
the flame sensor (sometimes referred to as a cad cell). The flame sensor is
mounted inside the burner cover, and faces the flame. The flame sensor
monitors the light level inside the combustion chamber to ensure a flame is
present. If there is a loss of flame 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 flame is established, the burner
will continue to function. If on start-up no flame 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 a set point
(usually 90º F), the fan/limit control will turn the fan off. If the
temperature exceeds a fixed set point, (usually 200º F), it switches the
burner (Oil Primary Control) off 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 firing the
unit is normally what causes this condition).
The fan/limit control also features an external switch to turn the axial fan
on manually, bypassing 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 preset chimney draft.
It is located in the chimney connector or flue.
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-off valve, (it’s open during operation, and closed when the
burner is off ). The electric air -solenoid valve is located inside the
burner’s electrical box.
Air Operated Fuel Valve
The air-operated fuel valve controls fuel flow out of the nozzle. When the
electric airsolenoid valve opens and air pressure pushes on the fuel valve
diaphragm, the plunger moves off 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 predetermined 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 preheater
assembly with two resistance type cartridge-heating elements. The snap disc is
mounted on the oil preheater inside the burner.
Nozzle
The nozzle uses air pressure to help deliver fuel through its small orifice,
and to atomize the fuel for proper combustion. The nozzle is located on the
end of the air preheater 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.

Section 4 – Chimney/Vent System
! Failure to provide proper venting of the heater exhaust gases could result
in death, serious injury, and/or property damage. FOLLOW CHIMNEY MANUFACTURERS
INSTRUCTIONS.
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 and paint booths may cause draft problems.
2. Never vent this heater into another heating appliance’s 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.
4. A U.L. listed barometric damper MUST be installed in the chimney or the
WARRANTY WILL BE VOID. Do not reduce or enlarge the vent pipe.
5. Minimize or eliminate horizontal runs and angle/elbow connections, where
possible. Consider chimney cleanout access when installing. If your
installation fails to achieve proper draft, consider lengthening the vertical
chimney.
Contact Lanair for Assistance with special installation circumstances.
6. To prevent the drawing of exhaust gases into the building, keep the
barometric draft control at least 2 to 3 feet from any fan, blower, etc..
7. The position of the draft control Barometric Damper gate hinge 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. Clearance for the chimney connector and any single-wall flue to any
combustible material is 18″. The “Class A” chimney clearance to any
combustible is 2″. Follow the chimney manufacturer’s instructions.

General Requirements (cont.)
Section 4 – Chimney/Vent System
10. Do not install heat re-claimers, manual draft controls, or any other type
of restrictive control(s) 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 or 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-turbine chimney cap. In areas of high wind, a
swivelling wind-guard cap may be appropriate. 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 -0.02 W.C. draft when
cold and -0.05 W.C. draft when hot
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.
NOTE: Do not install chimney in front of the heater (in air stream of fan)
Chimney Draft Requirements
The Lanair heater should have a (negative) -0.02 draft reading when cold, and
a (negative) -0.05 when hot. Check the heater after it has been running for 45
minutes. If the reading is not what it should be, adjust the barometric damper
to achieve proper draft. The draft reading should be measured with the
manometer included with the heater, or a comparable alternative. Consult your
heating contractor when needed.

Section 4 – Chimney/Vent System
Alternate Chimney Configurations
Some installation configurations may require orienting the chimney flue through
the exterior wall, rather than the roof, or utilizing the top exhaust port of the heater,
1
rather than the side port. Please consult with Lanair for guidance in these cases.
It is always preferable to install the chimney flue through the roof in order to ensure proper draft and minimize horizontal connectors that can collect debris and moisture. If installing the chimney through an exterior wall, be sure to adhere to height, clearance, and material requirements.
2 In most structures, using the side exhaust port of the heater makes it
easier to install the heater and maintain height and clearance require-
ments. If utilizing the top exhaust port, be sure to adhere to height,
3
clearance, and material requirements. If using the top port, the installed
cap must be removed and placed on the side port using the screws pro-
vided.
Vertical chimney must be a minimum of 10 feet in length to establish proper draft
Horizontal chimney-connector length should be minimized

Section 4 – Chimney/Vent System
Barometric Damper
The barometric damper balances the draft through the combustion chamber and
allows for adjustments. It can be installed in various chimney orientations,
but ensure that the barometric damper is installed with the pivot hinge
parallel to the ground with the attached weight closing the door when no draft
is present. Adjusting the weight clockwise (bringing the weight closer to the
damper door) will allow the door to open more when a draft is present,
increasing the draft through the damper and decreasing the draft through the
combustion chamber (lowering the manometer reading). Adjusting the weight
counter-clockwise (taking the weight farther from the damper door) will cause
the door to open less when a draft is present, decreasing the draft through
the damper and increasing the draft through the combustion chamber (raising
the manometer reading). NOTE: Keep the damper free of dust and debris and
check for proper draft daily

Section 6 – Fuel Supply Pump/Piping
General Requirements
1. Mount the fuel supply pump in a horizontal position (shaft horizontal)
near the fuel supply tank.
2. The standard oil pump has a maximum suction lift of 14 feet (6 feet for a
metering pump). Suction lift is the length of pipe run from the bottom of the
pick-up strainer to the fuel supply pump. Tall tanks and/or cold fuel may
require additional fuel-delivery equipment to properly supply the heating
system.
3. The fuel pump/motor are intended for indoor use only. 4. Clean all lines,
fittings, and parts internally before assembly. A small burr or piece of
rust could plug the nozzle. See Section 5 for an illustration of a typical
pump and piping installation.
5. The fuel pump contains an internal strainer that periodically needs to be
cleaned. This internal strainer is mounted behind the pump cover. Before
removing the pump cover make sure you have a new gasket on hand. Contact the
Lanair Customer Service Department for the proper gasket for your model of
pump, at 1-888-370-6531.
6. Use 1/2″ interior diameter (.493) steel pipe, or 1/2″ outside diameter
copper throughout the suction supply line and pick up tube. The use of smaller
line, rubber, plastic or hydraulic line is unsafe and will void your warranty.
7. Use thread sealing compound on all pipe thread connections. Do Not Use
Teflon Tape. 8. Install the suction line strainer in the suction line. Make
sure the suction line strainer is 6″ off
the bottom of the tank. The suction line strainer may be mounted horizontally
or vertically. Consider accessibility. 9. Install the check valve (arrow
facing towards the pump) on the bottom of the pick up tube. 10. Install a
vacuum gauge on the primary strainer assembly. This gauge will indicate when
service is needed on the strainer, pump or connections. 11. When using a
bypass regulator, install a 1/2″ inside diameter (.493) steel pipe, or 1/2”
outside diameter copper from the fuel bypass regulator (port marked “T”) to
the fuel supply tank. Do not allow this line to protrude into the tank more
than 1″. The use of smaller line, rubber, plastic, or hydraulic line is unsafe
and will void your warranty. When using the optional Metering Pump install a
3/8″ copper line from the tee on the metering pump assembly to the fuel supply
tank. Do not allow this line to submerge below the level of the oil. The use
of smaller line, rubber, plastic, or hydraulic line is unsafe and will void
your warranty.

Section 6 – Fuel Supply Pump/Piping
12. Do not allow the fuel level in the tank to cover the outlet of the return
line.
13. When using a bypass regulator install the fuel supply line from the fuel
bypass regulator (port B) to the inlet port on the left side of the burner
using 1/2″ inside diameter (.493) steel pipe, or 1/2″ outside diameter copper
tubing. The maximum distance of this line is 25 feet. The fuel supply line
must be run below the burner at all times. If the fuel supply line runs above
the burner it will create head pressure. This head pressure will over-fire the
burner voiding the warranty.
When using the optional metering pump install the fuel supply line from the
pump assembly to the burner.
14. Keep the fuel supply lines a minimum of 1″ from any exterior walls of the
building.
15. The fuel supply line must gradually rise to the burner. It should not be
higher than the burner. Avoid creating any high points in the line that will
trap air bubbles.

Waste Oil Burner Start-Up
Section 10 – Burner Startup Procedure
1. Make sure the main electrical service for the heater is turned off, and locked out.
2. Check for proper draft in the chimney. Confirm that there is no positive- draft pressure (air coming DOWN the chimney, usually caused by roof-vent exhaust fans).
3. Make sure there is air pressure at the heater’s air filter/regulator, set at 20 PSI (idle pressure, 15 PSI while heater is running). Set the primary regulator on the air supply line to 30 PSI.
4. Ensure that the fan/limit control switch is set to automatic.
5. Set the room thermostat below room temperature (OFF).
6. Turn the main electrical service ON.
7. If using waste 5W-50W used oil, flip the pre-heater rocker switch on, light ON, and wait 5-7 minutes for the pre-heater assembly to reach operating temperature. Leave the preheater switch OFF if using No. 2 fuel oil.
8. Set the air-baffle position according to your unit:
XT-150 XT(D)-200, XT-250 XT(D)-300
1/4 open (burner air-intake grill 25% exposed) 1/2 open (burner air-intake grill 50% exposed) 3/4 open (burner air-intake grill 75% exposed)
These are preliminary positions for the air baffle and may be adjusted during a later step.
9. Turn the room thermostat up above the room temperature. The burner will
now fire. Check the sight glass on the rear of the burner. Also inspect the
flame through the inspection port. (See Section 11 – Flame Adjustment).
10. Adjust the burner air filter/regulator to 15 PSI (running pressure), and
the primary air regulator to 30 PSI.
NOTE:15 PSI on the air filter/regulator is the starting point, you may need to
adjust from there when VISUALLY SETTING THE FLAME (See Section 11, flame

the walls, filling the chamber with a smokey flame. Correct immediately or
chamber may be damaged.
Flame is over-fired Problem: Too large of a flame, dark yellow in color. Ash
inside the chamber is dark brown to sooty-black in color
· Too much fuel pressure: decrease fuel pressure at bypass regulator (not
applicable for metering pump)
· Not enough combustion air: increase opening of burner air baffle · Not
enough atomizing air pressure: increase atomizing-air pressure (adjust in 1
psi
increments; too much atomizing air can also cause “pulsing” of flame) · Oil
too cold: check to see if preheater block is hot
DO NOT OVER FIRE YOUR HEATER. IMMEDIATELY ADJUST THE BURNER TO THE PROPER
FLAME LENGTH TO PREVENT DAMAGE TO YOUR HEATER.
CHECK FLAME DAILY (see page 37). ADJUST ACCORDINGLY

Cleaning Combustion Chamber/ Heat Exchanger 1. Turn thermostat to the lowest
setting; the heater must be completely cool to the touch
before attempting to clean the heater (place the fan/limit on the manual
position to start the fan and shorten the cooling time if the unit is hot).
2. Turn off all power to the heater (120 VAC) at the main disconnect.
3. Disconnect the burner cord connecting the burner to the heater.
4. Remove the burner and flame view port from the heater.
5. Remove the galvanized panel covering the cleanout door (remove five (5)
10 screws from the top and four (4) #10 screws from the bottom of the panel).
6. Spray all of the screws with penetrating oil to prevent
breakage before removing any of the nuts that secure
the combustion chamber access door. Let set for five
minutes to allow the oil to penetrate.
Do not remove (4)
7. Open the clean out door from the heater by removing (8) 1/2 hex head nuts & washers.
8. Clean the heat exchanger chamber and tubes by using an industrial type canister vacuum cleaner with a high efficiency filter, or suitable tool. Remove ash and debris by vacuuming, shoveling, or slowly brushing the ash from the combustion chamber, from the front or rear access. Inspect the combustion chamber and target brick. Use care when cleaning the combustion chamber area so the target brick is not disturbed.
Insufficient or irregular cleaning intervals will cause inefficiency, random shutdowns, and extreme damage to the combustion chamber.

Section 13 – Troubleshooting
Initial Diagnosis: When an operating problem occurs, a determination must be
made whether or not the fuel pump is pumping a sufficient amount of oil that
contains no air or water. Take these steps: · Turn the thermostat off or to a
temperature below room temperature · Disconnect the fuel supply line from the
burner. · Insert the fuel line into the bottom of a large jar. · Toggle the
priming switch from the “RUN” position to the “PRIME” position · Attempt to
fill the container, keeping the fuel line above the tank’s fuel level. · A
steady stream of oil should flow from the fuel line · If the pump will not
pump fuel, attempt to prime the pump (Section 9). If the pump won’t
prime refer to troubleshooting chart symptom B.
When using the optional metering pump: Pump fuel into a graduated container.
The flow rate will vary by model.
XT-150 . . . . . . . . . . . . . . . . . . 1.1 gal/hr (69 ml/min) XT(D)-200 .

incorrect by more than +/- 10%, contact Lanair Service at
888-370-6531. After repairs are made,
toggle the priming switch from the “PRIME” position to the “RUN” position,
reconnect the fuel-supply line to the burner, and reset the thermostat.
